Cisco 350-601 Dumps

Option C is the correct command to make an XML backup of Cisco UCS Manager. The command creates a backup file named “all-config9.bak” that contains all system and service profiles configuration. The command also specifies the protocol as SCP (Secure Copy Protocol), which transfers the backup file using an authenticated and encrypted tunnel. References:

Enabling the vPC peer gateway feature on the vPC devices allows them to act as the active gateway for packets that are addressed to the router MAC address of the vPC peer. This capability allows both vPC peers to forward traffic and eliminates traffic disruption when one of them goes down, ensuring high availability in network operations.

References: = For more detailed information, you can refer to the Cisco Nexus 9000 Series NX-OS High Availability and Redundancy Guide, which provides guidelines on configuring vPC peer gateway features for enhanced network stability and availability.

 In Cisco ACI, an interface policy group can be linked to multiple Attachable Access Entity Profiles (AAEPs) to support connectivity for various EPGs with L3Outs. This setup allows for the concurrent support of L3Out connectivity and multiple EPGs on a single access port. References: This concept is covered in the section on ACI access policies in the DCCOR course.

 Option B is the correct configuration set that meets the requirements for the SAN users’ role. This configuration allows users to have show access to the system, SNMP, module, and hardware information, run debug zone and exec fcping commands, and restricts access to the show feature environment command2.

 Static ingress replication is a method used in VXLAN environments where the replication of multicast, broadcast, and unknown unicast traffic is manually defined. In the context of Cisco Data Center Core Technologies, Option A implements static ingress replication by explicitly specifying peers for replication using the ingress-replication protocol static command followed by the peer-ip command to define the IP address of the replication peer. This configuration is necessary when multicast routing is not an option in the underlay network.

References := For further details, one would typically refer to Cisco’s official documentation on VXLAN configurations and the Implementing and Operating Cisco Data Center Core Technologies (DCCOR) study materials, which provide in-depth explanations on the setup and management of network overlays including static ingress replication.

The following example modifies an overridden policy by changing the number of FCNS database entries to

1500. It also generates both the configured and the default syslog messages of the default system policy

event manager applet fcns_policy override __fcns_entries_max_per_switch

event fcns entries max-per-switch 1500 action 1.0 syslog priority warnings msg FCNS DB entries have reached the EEM limit.

 The checkpoint named “system-fm-vrrp” was created by an admin, as indicated by the description “Created by Feature Manager.” This suggests that it was a deliberate action rather than an automatic response to a service restart or crash. Checkpoints in Cisco systems can be manually created for various reasons, such as before making significant changes to the configuration, which allows for a rollback to a known good state if necessary.

References := For more information on the creation and management of checkpoints in Cisco systems, one should refer to the Cisco Data Center Core Technologies documentation and study materials, which provide detailed procedures and best practices.

When connecting a Cisco UCS Fabric Interconnect (FI) directly to an external storage array using a Fibre Channel (FC) storage port, it is essential to configure the FI in FC switch mode. This mode allows the FI to manage FC traffic and zoning, which is necessary when bypassing an upstream SAN switch. Additionally, creating the required Virtual Storage Area Network (VSAN) within the SAN cloud is crucial for isolating and managing the traffic between the FI and the storage array. The VSAN provides a unique identifier that enables the direct connection and communication between these devices.

References: The configuration steps for direct attachment of a storage array to a Cisco UCS FI are detailed in Cisco’s official documentation and support forums1. Specifically, the process involves setting the FI in FC switch mode and creating the necessary VSAN for the connection1. These references provide guidance based on Cisco’s recommended practices for such configurations.

 Configuring an IP helper address on interface VLAN 10 of the management switch is the correct action to meet the requirements. This configuration allows the management switch to forward DHCP requests from the new switches in different VLANs to the DCNM server, which can then use the zero-touch POAP feature to facilitate fabric creation.

 In the provided configuration, the commands are used to configure a Fibre Channel interface on a Cisco Nexus 5000 Series switch. The “interface fc2/3” command is used to enter the interface configuration mode for the specified Fibre Channel interface. The “switchport mode sd” command configures the Fibre Channel interface for synchronization distribution (SD). SD is a feature that allows the distribution of clocking information through the network to synchronize different parts of a system.

References: The Implementing and Operating Cisco Data Center Core Technologies (DCCOR) course provides detailed information on configuring Fibre Channel interfaces, including synchronization distribution12. Additional resources can be found in Cisco’s data center certification materials3

 When configuring an Intersight virtual application and claiming targets, the information required in the comma-separated value (CSV) file for provisioning includes the target type, hostname or IP address, user name, and password. This set of information is necessary to uniquely identify and authenticate each target for the claim process.

References := The requirements for the CSV file format for claiming targets in Cisco Intersight can be found in the official Cisco documentation on the Intersight Virtual Appliance and Intersight Assist Getting Started Guide

Option C and Option D are correct because they configure the SPAN session to monitor the source interface ethernet 1/16 and send the traffic to the destination interface ethernet 1/3. These options also include the use of the type SPAN-on-DROP command, which ensures that only dropped packets are sent to the analyzer, thus conserving disk space.

 NX-API is a feature that enables the use of JSON and XML encoding when a Cisco Nexus 7000 series switch is deployed. NX-API is a RESTful API that allows external applications to communicate with the switch using HTTP/HTTPS requests and responses. NX-API supports JSON and XML as the data formats for encoding and decoding the requests and responses. By using NX-API, external applications can access and configure the switch features and functions without using the CLI or SNMP. NX-API also provides a sandbox mode that allows users to test and validate their API calls before applying them to the switch. References :=

• Implementing and Operating Cisco Data Center Core Technologies (DCCOR) v1.2, Module 3: Data Center LAN Network Connectivity, Lesson 3.4: Cisco Nexus 9000 Series Switches
• Cisco Nexus 7000 Series NX-OS Programmability Guide, Release 8.x, Chapter: Using NX-API

 Promiscuous mode (D) allows a virtual machine to observe all traffic on the virtual switch, which is necessary for the virtual machine to receive all frames. VLAN (E) is used to map the frames to a specific Layer 2 network. These settings ensure that the virtual machine receives all traffic for the specified VLAN, fulfilling the requirements stated in the question1.

References: The configuration details and the role of these settings can be found in the Cisco documentation related to VDS port group parameters managed by APIC

NFSv4 offers several advantages over Fibre Channel protocol, one of which is improved security. NFSv4 is designed to be more secure than its predecessors, providing strong security features that are not inherent in Fibre Channel. It includes mechanisms for authentication, integrity, and privacy, which are part of its standard protocol suite. NFSv4 also integrates well with security infrastructures like Kerberos, allowing for secure, authenticated access to file systems over a network.

 Changing the default host firmware policy in Cisco UCS Manager affects any service profile that uses the global-default host firmware policy. This is because the global-default host firmware policy serves as a template for service profiles that do not have a specific host firmware policy defined. When changes are made to the default policy, they propagate to all service profiles that reference it, potentially affecting the firmware version and settings across multiple servers.

References: 350-601 DCCOR exam topics2.

On Nexus switches, the equivalent command to save the configuration to NVRAM is ‘copy running-config startup-config’. The ‘write memory’ command is specific to Catalyst switches and is not used on Nexus switches.

To create a virtual Fiber Channel interface and associate it with an Ethernet physical interface, the correct configuration commands would be:

• Enter the interface configuration mode for the virtual Fiber Channel interface using the command interface vfc7.
• Bind the virtual Fiber Channel to the Ethernet interface using the command bind interface ethernet 1/7.

This configuration associates the virtual Fiber Channel interface with VSAN 7 and maps VLAN 700 to the VSAN, as required by the converged network adapter (CNA).

References := The explanation is based on standard practices for configuring virtual Fiber Channel interfaces in a Cisco environment, as detailed in Cisco’s data center configuration guides and technical documentation.

 Embedded Event Manager (EEM) is a powerful tool used in Cisco devices, including MDS switches, to automate tasks and create custom scripts that react to network events. For an administrator needing to configure an automated policy to shut down a link when a threshold is exceeded, EEM is the appropriate feature to use. It allows the creation of event-driven automation scripts that can be triggered when certain conditions are met, such as a link exceeding a specified threshold.

References: Cisco Data Center Core Technologies (DCCOR) training materials and Cisco’s official documentation on EEM.

 Option A is the correct configuration to use the DNS server with IP address 192.168.1.1 on a Cisco UCS Fabric Interconnect. The engineer needs to scope the system settings, create a DNS entry with the IP address, and commit the buffer. The other options have incorrect commands or syntax errors. For example, option B uses the wrong command to set the name of the fabric interconnect, option C uses the wrong command to create the DNS entry, and option D uses the wrong command to scope the system settings. References:

• [Cisco UCS Manager CLI Configuration Guide, Release 4.0 - Configuring System Settings [Cisco UCS Manager]], Configuring System Settings, Configuring DNS

The location where the engineer can look for the latest core dump file after a Cisco MDS 9000 series storage switch has reloaded unexpectedly is /mnt/core. A core dump file is a file that contains the memory state of the kernel at the time of a system failure. The core dump file can help the engineer or the Cisco technical support to analyze the cause of the problem and to fix it. The core dump file is stored in the /mnt/core directory on the switch, and it can be accessed using the CLI command ‘show cores’ or ‘utils core active list’. The other directories (/mnt/pss, /mnt/logs, and /mnt/recovery) do not contain the core dump file, but they may contain other useful information for troubleshooting, such as process state information, log files, and recovery files.

• Troubleshooting Core Dumps
• Cisco MDS 9000 Family Kernel Core Server Installation and Configuration Guide

Option C meets the security hardening requirements for Cisco UCS C-Series servers’ out-of-band management. It ensures that all traffic is encrypted, uses nondefault ports, and provides private administrative sessions, which align with the company’s security policy

PowerShell is a task automation and configuration management framework from Microsoft, consisting of a command-line shell and the associated scripting language. It is integrated with Cisco UCS Manager and provides cmdlets for automating the management of Cisco UCS domains, including Service Profiles. The UCS PowerTool is a set of PowerShell modules designed specifically for Cisco UCS, making it a suitable choice for a network engineer with scripting skills but limited programming knowledge. It supports configuration tasks for both B-Series Blade Servers and C-Series Rack Servers, aligning with the administrator’s future needs.

References: Cisco Community discussions on UCS PowerTool + Service Profiles1 and the Cisco UCS PowerTool Scripts Index

 To install an operating system on a LUN provided by the Fibre Channel storage array, the engineer needs to configure the boot policy to include a SAN Boot Target with a WWPN (World Wide Port Name). This ensures that the server can communicate with the specific LUN on the storage array during the boot process. Additionally, adding Local CD/DVD and SAN Boot in the boot policy provides flexibility for installation sources, ensuring that both local and networked storage options are available during boot. References := Cisco Data Center Core Technologies source documents or study guide

The Device Connector Access Mode should be configured as ‘Allow Control’ within the Cisco UCS Manager to enable full configuration capabilities. Claiming the device on Intersight as ‘UCSM Managed Mode’ ensures that the device can be managed through both the Cisco UCS Manager and the Intersight platform. This configuration aligns with the best practices for setting up Cisco UCS domains for integration with Intersight, allowing for seamless monitoring and management while maintaining security and control12.

References := For further details on the configuration process and best practices, you can refer to the Cisco Intersight Managed Mode Configuration Guide and other official Cisco documentation related to UCS domain profiles and Intersight integration

 In a vPC (Virtual Port Channel) environment, broadcast packets received on the vPC peer link are not forwarded out on the vPC member ports. This behavior is due to the vPC loop avoidance rule, which prevents traffic received on a vPC peer link from being sent back out of the vPC member ports. Therefore, the Agg-1 switch will prevent broadcast packets that arrive on the vPC peer link from exiting the switch on ports Eth2/4 and Eth2/5.

References: For more detailed information, you can refer to the Implementing and Operating Cisco Data Center Core Technologies (DCCOR) course, which covers the essentials of vPC operations and the loop avoidance mechanism

For traffic monitoring with fabric failover enabled, it’s important to ensure that traffic can still be analyzed even if one of the fabric interconnects fails. By creating two separate traffic monitoring sessions, each with a unique name and connected to an analyzer on each fabric interconnect, you can maintain continuous monitoring. This setup ensures that traffic is sent to the analyzer regardless of the state of either fabric interconnect.

References: For more detailed information, please refer to the official Cisco documentation on their website or the specific study materials for the Cisco Data Center Core Technologies certification.

• Setting the RADIUS source interface to be mgmt0 for group RAD1 and VLAN 22 for group RAD2 © ensures that login requests from the console and SSH are sourced from the correct interfaces and reach the appropriate RADIUS server.
• Configuring the authentication login to use group RAD1 for console and group RAD2 for remote access (D) directs the switch to use the specified RADIUS server groups for the respective login methods, aligning with the user’s requirements.

These configurations ensure that management access via console and SSH is authenticated through the designated RADIUS servers as intended. It’s important to apply these settings correctly in the switch’s configuration to achieve the desired access control.

The command in question is likely to temporarily suspend the Protocol Independent Multicast (PIM) join messages. This action does not delete the PIM database or flush the Multicast Routing Information Base (MRIB), nor does it suspend multicast traffic forwarding. Instead, it interrupts the PIM join messages, which are used to build and maintain the multicast distribution tree.

References := For an in-depth explanation, one should refer to the Cisco Data Center Core Technologies study materials, which cover the PIM protocol and its behaviors in detail.

When configuring a vHBA template in Cisco UCS Manager, the engineer needs to specify the logical addresses used by the vHBA and the path through which the SAN traffic flows. The two resources that must be specified in the vHBA template are the WWN (World Wide Name) and the Fabric ID. The WWN is a unique identifier for the vHBA that is used for zoning and LUN masking in the SAN environment. The WWN can be assigned manually or automatically from a WWN pool. The Fabric ID is a parameter that determines which fabric interconnect (A or B) the vHBA is associated with. The Fabric ID can be set to a specific value or to ‘default’, which allows the system to choose the best available fabric interconnect based on the availability and load balancing policies. References :=

The command “ldap-server host 10.10.2.2 enable-ssl” is used to configure AAA authentication on an MDS 9000 switch with an LDAP server located at the IP 10.10.2.2. This command ensures that the data sent to the LDAP server is encrypted using SSL, which is a protocol for securing network communication.

References: For more information, refer to the Cisco Data Center Core Technologies (DCCOR) study guide or source documents, specifically the sections covering AAA authentication configuration and LDAP server integration with MDS 9000 switches.

 In the context of Cisco Data Center Core Technologies, SPAN (Switched Port Analyzer) is used to monitor network traffic. To configure a SPAN session on a Nexus 5000 series switch, an engineer would need to use specific commands. Option A, “Configure the switchport monitor under interface fc2/2,” is correct as it involves setting up the monitoring port under a specific interface. Option D, “Configure session type fc under monitor session 1,” is also correct as it specifies the type of session being configured for monitoring.

References := The explanation can be corroborated with detailed study from Cisco’s official documentation and resources available on their website or the Cisco Data Center Core Technologies source book.

 Before enabling a Cisco UCS Manager domain for Cisco Intersight connectivity, you must configure the DNS servers and the NTP servers for the domain. The DNS servers are required to resolve the hostname of the Cisco Intersight service (svc.intersight.com) and the NTP servers are required to synchronize the time between the Cisco UCS Manager and the Cisco Intersight service. These settings ensure that the Cisco UCS Manager can establish a secure and reliable connection with the Cisco Intersight service and register the domain with the Cisco Intersight account.

 To meet the requirements of using the secondary interface and then falling back to the primary interface when it becomes available again, the engineer should enable the Uplink failover option in the vNIC properties of the Cisco UCS Cisco Integrated Management Controller (CIMC) network adapter for a standalone Cisco C-Series server. The Uplink failover option allows the vNIC to switch to the secondary interface in case of a failure in the primary interface, and then switch back to the primary interface when it recovers. The Uplink failover option also allows the engineer to configure the Fallback Timeout value, which determines how long the vNIC waits before switching back to the primary interface. In this case, the Fallback Timeout value is set to 600 seconds, which means the vNIC will wait for 10 minutes before falling back to the primary interface. References :=

 Option C is the correct adjacency server configuration to make two OTV edge devices located in the same site bring up the dual-site adjacency. The adjacency server is a logical entity that maintains the control plane information for the OTV overlay network. The adjacency server can be configured in unicast-only mode, which means that the OTV edge devices use unicast packets to exchange control plane information. To enable dual-site adjacency, which means that the OTV edge devices can form adjacencies with devices in the same site as well as devices in different sites, the adjacency server must be configured with the same IP address on both devices in the same site. The other options have incorrect configurations or IP addresses. For example, option A uses different IP addresses for the adjacency server on the same site, option B uses the same IP address for the adjacency server on different sites, and option D uses an invalid IP address for the adjacency server. References:

The statement that is true about the behavior of multiple roles applied to a user on the Cisco MDS 9000 Series Switch is that access to a command takes priority over being denied access to a command. This means that if a user has multiple roles assigned and one of the roles grants access to a command while another role denies access to the same command, the user will be able to execute the command. The access permission overrides the deny permission in case of a conflict. The other statements are not true because:

• Any commands that have conflicting settings between roles are not denied. As explained above, the access permission prevails over the deny permission in case of a conflict.
• The first role assigned does not take precedence over subsequent roles. The order of role assignment does not affect the command authorization. All roles assigned to a user are evaluated together and the most permissive setting is applied.
• The last role assigned does not take precedence over previous roles. The order of role assignment does not affect the command authorization. All roles assigned to a user are evaluated together and the most permissive setting is applied. References: For more information on how to configure and manage roles on the Cisco MDS 9000 Series Switch, please refer to the following resources:
• Cisco MDS 9000 Family NX-OS Security Configuration Guide

Option C is the correct configuration that is expected to be saved by using a logical configuration backup. A logical configuration backup includes the service profiles, service profile templates, policies, pools, and logical LAN and SAN connectivity configuration. It does not include the systems, roles, or servers configuration, which are part of the full state or all configuration backups. References:

To meet the requirements of building a lab replica of a Cisco UCS production environment, the file must be exported in XML format using an encrypted method. Option B, Protocol SCP (Secure Copy Protocol), is used for securely transferring computer files between a local and a remote host or between two remote hosts. Option C, Type Full state, ensures that the complete configuration and state are included in the exported file. References:

 In a Cisco ACI fabric, when implementing a Virtual Machine Manager (VMM) domain, VLANs can be allocated dynamically or statically within a VLAN pool. To incorporate a static VLAN into a dynamic VLAN pool, the correct approach is to add a static VLAN allocation range to the VLAN pool. This allows for the specific VLAN to be reserved and used consistently for certain applications or services, while still maintaining the flexibility of dynamic allocation for other VLANs within the pool.

• Enable telemetry features on the Cisco Nexus 9000 Series Switch to collect and send real-time data.
• Configure a secure transport mechanism, such as gRPC with TLS encryption, to ensure that the monitoring data is transmitted securely.
• Set up a subscription-based monitoring service that can process the telemetry data and provide insights into the network health.

The ‘all configuration’ backup type in Cisco UCS Manager includes both system and logical configuration settings. This backup type is an XML file that encompasses all system and logical configurations, making it suitable for scenarios where a complete backup of all settings is required

 To meet the requirement of collecting show command data every 30 seconds and sending it to receivers, the command must specify the sample interval in milliseconds. Therefore, the correct command is Snsr-grp 200 sample-interval 30000, which sets the sample interval to 30,000 milliseconds (equivalent to 30 seconds).

References := The configuration details for streaming telemetry on a Cisco MDS 9000 series switch can be found in the Cisco MDS 9000 Series SAN Analytics and SAN Telemetry Streaming Configuration Guide1.

 Option D and C are the correct policies that must be configured to meet the requirements. A Maintenance Policy specifies how the changes are applied when a service profile is associated or disassociated with a server or when an updated service profile is applied to a server. A Power Control Policy allows users to select how Cisco UCS Manager should restore power to the servers in a chassis after the chassis loses power. References:

Cisco UCS Manager supports various types of authentication mechanisms for enhanced security. Option A (local) refers to the use of locally stored user credentials within the UCS Manager for authentication. Option B (LDAP) indicates that UCS Manager can integrate with LDAP (Lightweight Directory Access Protocol) directories for user authentication, allowing centralized management of user credentials. References: Cisco Data Center Core Technologies source documents or study guide

The correct command to configure the source IP address on switch1 for mirroring traffic to a packet sniffer located on switch2 is option B, “monitor erspan origin ip-address 209.165.200.225”. This command sets the origin IP address for the Encapsulated Remote SPAN (ERSPAN) session, which allows traffic from a source port on one switch to be monitored on a destination port on another switch across an IP network.

 The configuration set that meets the requirements for configuring port security on a Cisco MDS 9000 Series Switch is Option C. This option includes the command port-security activate vsan 4 force, which initiates the VSAN 4 port security database despite any conflicts. It omits the auto-learn command, indicating that new devices must be added manually. Additionally, the port-security distribute command ensures that configuration changes are applied throughout the fabric and any locks on the fabric are released, as required1.

NFS (Network File System) is a distributed file system protocol that allows users on client computers to access files over a network in a manner similar to how local storage is accessed. NFS uses a Kerberos-based security model to provide authentication, integrity, and confidentiality of data. It ensures that unauthorized users do not have access and protects the data from eavesdropping and tampering as it moves across the network. The other options are not features of NFS. Role-based access control is a method of restricting access to resources based on the roles of users. Block-based file access is a type of storage access that transfers data in fixed-sized blocks. Zone-based access control is a feature of Fibre Channel SANs that allows traffic isolation within a VSAN. References:

The question involves an engineer configuring a Cisco MDS 9000 Series Switch and noticing that the name server with IP 192.168.10.11 is missing from the configuration. The correct action to complete the configuration is option C, “Enter yes at step 21 to edit the configuration. Add the line dns-server 192.168.10.11.” This step allows the engineer to modify the initial setup process’s outcome by adding the missing DNS server information directly into the configuration before saving it.

The configuration shown in the exhibit indicates that FCIP (Fibre Channel over IP) is configured with ip-compression mode2 enabled on a Cisco MDS 9000 Series switch. This means compression is performed by using software (Option D), as mode2 refers to software-based compression in FCIP configurations. The other options are not correct based on the configuration. The switch does not attempt to make two TCP connections, as there is no tcp-connections command in the configuration. Compression is not performed by using hardware, as mode1 refers to hardware-based compression in FCIP configurations. Mode2 is not enabled by default, as the default mode for FCIP compression is none. References:

 In a vPC (Virtual Port Channel) data center interconnect, both vPC peer devices must have the same system MAC address to ensure that remote switches perceive them as a single logical switch. Since the system MAC value on SW1 is 00:23:04:ee:be:20, the same value must be configured on SW3 to maintain consistency in the vPC domain and ensure seamless communication between the two data center fabrics connected through this vPC interconnect.

References: = The explanation can be inferred from Cisco’s official documentation and resources related to configuring and managing vPCs, ensuring that both peer devices in a vPC domain are configured with identical parameters, including the system MAC address.

To achieve the most optimal on demand CPU performance while configuring the BIOS settings of a UCS C-series rack mount server, you should set the CPU Performance option to C0/C1 state. This option enables the CPU to operate in the highest performance state (C0) or the lowest power state (C1) depending on the workload demand. This allows the CPU to maximize its performance and efficiency without compromising its thermal and power limits. The other options (C6 Retention, C2 state, and C6 non-Retention) reduce the CPU performance by putting the CPU into deeper sleep states (C2 or C6) when idle, which can increase the latency and power consumption when resuming the CPU activity. References: For more details on how to configure the BIOS settings of a UCS C-series rack mount server, please refer to the following resources:

In a multihomed OTV network, it is essential to configure the remote OTV AEDs (Authoritative Edge Devices) to use both the primary and secondary adjacency servers for redundancy and resiliency. The correct configuration, Option D, includes the otv use-adjacency-server command with both IP addresses of the primary and secondary servers followed by unicast-only, which indicates that the AEDs should use unicast connections to the adjacency servers instead of multicast.

References := This configuration aligns with best practices for setting up OTV networks as described in Cisco’s Data Center Core Technologies documentation. For a more comprehensive understanding, refer to the study materials related to OTV configurations in the Cisco Data Center Core Technologies (DCCOR) course.

The vsan bind interface command is used to statically assign VSAN membership to a virtual Fibre Channel interface. This command overrides the VSAN membership that is derived from the physical interface or the default VSAN.

The In-Service Software Upgrade (ISSU) process is designed to upgrade the system software with minimal disruption to the network. Nonstop forwarding (NSF) and stateful switchover (SSO) are two features that work together to maintain packet forwarding and switch state information during the ISSU process. NSF allows the router to continue forwarding packets even when the route processor is failing over, while SSO synchronizes state information between redundant route processors to ensure a seamless transition during a failover1.

References := For a deeper understanding of the ISSU process and its associated features, you can refer to Cisco’s official documentation on In-Service Software Upgrade (ISSU), which provides detailed information on how NSF and SSO contribute to a nondisruptive upgrade

The Cisco UCS firmware Auto Sync Server policy includes several configuration settings that determine how and when firmware on servers is synchronized. The two available settings from the options provided are ‘User Acknowledge’ and ‘No Action’. ‘User Acknowledge’ requires an administrator to manually acknowledge firmware upgrades in the Pending Activities dialog box before they are applied. ‘No Action’ means no firmware upgrade is initiated on the server. These settings allow administrators to control the firmware synchronization process according to their operational policies and procedures.

To monitor all LAN traffic on Fabric A from a blade server, the source should be configured as all uplink Ethernet ports in the test-span monitor session. This configuration allows the engineer to capture all LAN traffic that traverses the uplink Ethernet ports, providing a comprehensive view of the network activity related to Fabric A. By monitoring these ports, the engineer can analyze traffic patterns, detect anomalies, and ensure the proper functioning of the network.

The virtual MAC address that is the default for HSRP version 2 group 10 is 0000.0C9F.F00A. HSRP (Hot Standby Router Protocol) is a protocol that provides redundancy and load balancing for IP networks by allowing multiple routers to share a virtual IP address and MAC address. HSRP version 2 supports up to 4096 groups, and uses a different MAC address format than HSRP version 1. The MAC address format for HSRP version 2 is 0000.0C9F.FXXX, where XXX is the hexadecimal value of the group number. For group 10, the hexadecimal value is 0A, so the MAC address is 0000.0C9F.F00A. References :=

The contract between EPG Client and EPG Web allows TCP communication initiated by the client toward the webserver with TCP destination port 80. This means that the host in EPG Client can establish a connection to the webserver in EPG Web on TCP port 80. However, the contract does not allow the webserver to initiate a connection back to the host on the same port, which is typically used for HTTP traffic.

References: The explanation is based on the understanding of Cisco Application Centric Infrastructure (ACI) contracts, which are used to define the communication between EPGs (Endpoint Groups). For more detailed information, refer to the Cisco Data Center Core Technologies source book and the ACI documentation available on Cisco’s official website.

 In Cisco ACI, TCAM resources can be optimized by configuring a single contract that is provided and consumed by all EPGs within a VRF. This approach ensures that all EPGs consume the same services, thus reducing the number of individual contracts and associated TCAM entries. By having a common contract, the ACI fabric can efficiently manage access control policies and service insertion without the need for multiple, redundant entries in the TCAM, which can lead to resource exhaustion. References: The information is based on the best practices for TCAM management in Cisco ACI fabrics, as detailed in the Cisco community discussions and Cisco’s official documentation on TCAM resource issues and workarounds12. Additionally, the concept of using a single contract for multiple EPGs is supported by the Cisco ACI Endpoint Security Group (ESG) Design Guide, which outlines the steps for implementing a single ESG for open communication between subnets (EPG selectors)

Cisco Data Center Network Manager (DCNM) is the monitoring solution that can fulfill the requirements of visualizing the SAN, supporting VXLAN overlays, and identifying storage slow drain issues for a Fibre Channel storage environment consisting of Cisco Nexus 9000 and MDS 9000 Series Switches3.

The issue with the implementation is that zones are local to the MDS switch, and name service must be used to activate the connection between E ports. In Cisco MDS switches, zoning is enforced at the switch level. Each switch in a fabric can have a different active zone set or none at all. The name server for each switch only contains information about devices that are logged into that specific switch.

The command ‘aaa authentication login default fallback error local’ is used to ensure that if RADIUS servers are unreachable, the system will fall back to using the local user database for SSH access to the Cisco MDS 9000 Series Switch.

 Option D is the correct choice. Configuring the vPC role priority and enabling the peer-gateway feature are recommended practices for enhancing vPC convergence times. The peer-gateway feature allows for local forwarding of packets without the need to cross the vPC peer link, which can significantly reduce convergence times during primary peer device failures and recoveries. This approach ensures that the vPC system can quickly adapt to changes and maintain traffic flow even in the event of a device failure123.

References: For more detailed information and best practices, you can refer to Cisco’s official documentation and community discussions on vPC convergence and failure scenarios

The requirement for the data center servers to reach services in the cloud and services behind redistributed routes, along with the condition that the exit point toward the internet should only be propagated when there is a dynamically learned default route, necessitates the use of the ‘default-information originate’ OSPF feature. This feature allows the advertisement of the default route in OSPF when it is present in the routing table, which is the case when it is dynamically learned from the upstream router.

References: The ‘default-information originate’ feature is part of OSPF configuration and is used to control the advertisement of default routes in an OSPF environment. This is further explained in the Cisco OSPF Configuration Guide, which details the use of this command to propagate default routes under certain conditions

Placing all EPGs in the preferred group within a VRF allows for communication between them without the need for additional contracts. This is because the preferred group feature in Cisco ACI allows EPGs within the same VRF to communicate with each other by default, bypassing the need to provide and consume contracts1. This simplifies the configuration process when new EPGs and bridge domains are added, as they inherit this communication capability by being part of the preferred group1.

References := For more information on the implementation of VRFs and the use of the preferred group feature in Cisco ACI, you can refer to the Cisco documentation on “Use vzAny to Automatically Apply Communication Rules to all EPGs in a VRF” and other related resources1. These documents provide detailed guidance on how to configure VRFs and EPGs to achieve seamless communication within the network infrastructure.

 To configure an application profile using REST API, the engineer needs to first authenticate with the APIC using the POST method to the aaaLogin URI. This will return a token that can be used for subsequent requests. The error message indicates that the token is missing or expired, so the engineer needs to perform the POST to aaaLogin method again before configuring the application profile. References := [Cisco APIC REST API Configuration Guide]

FC/FCoE oversubscription ratios refer to the relationship between the bandwidth provided and the bandwidth required. Common types of oversubscription ratios include port bandwidth to uplink bandwidth (B), which measures the bandwidth available at the access layer compared to the uplink, and host bandwidth to storage bandwidth (D), which relates to the bandwidth demand from servers compared to the available storage bandwidth.

 Option D is the correct statement about the Deployment Immediacy for VMM domains associated to EPGs when the APIC EPG Resolution Immediacy is set to “Immediate”. This means that the policy is pushed to the hardware as soon as the leaf switch is booted, regardless of whether there are any VMs in the EPG or not. This ensures that the policy is ready to be enforced as soon as a VM is created or moved into the EPG. References:

Cisco CloudCenter is the appropriate orchestration solution for the customer’s requirements. It supports the CI/CD model, which is essential for streamlining operations and optimizing costs. Cisco CloudCenter can integrate with Cisco ACI networking and Cisco UCS servers, providing a unified management platform. It also offers on-premises Kubernetes support and AppDynamics performance monitoring without the need to install local clients on managed products, aligning with the customer’s security requirements. References: Cisco CloudCenter documentation and Cisco Data Center Core Technologies study guide.

To complete the PowerOn Auto Provisioning (POAP) operation on a Cisco Nexus 9000 Series Switch, the script must include the necessary network information such as the interface IP address, gateway, and DNS server IP addresses. Option C likely contains this information, which is essential for the switch to locate a DHCP server, bootstrap itself, and download the configuration script for software image installation and configuration

The configuration in option C, which includes commands such as switchport port-security, switchport port-security violation restrict, and switchport port-security mac-address sticky, meets the security requirements specified. This configuration secures the end-user ports by limiting the number of MAC addresses allowed on the port, logs security breaches without shutting down the port (restrict mode), and retains the MAC address configuration even if the device restarts (sticky option).

The configuration set in Option C is designed to invoke a Python script when the router becomes unreachable. It uses an event scheduler to track the state of the router and, if it is not up, it triggers the Python script “routerdown.py” at specified intervals. This setup ensures that the operations team is alerted promptly when the router DC-RTR-1 becomes unreachable, allowing for quick response and troubleshooting.

Ansible meets the requirements as it uses SSH for transport, does not require agent software to be installed on managed systems, and uses YAML for its playbooks, which is a human-readable data serialization standard, making it easy to read and use for people with limited knowledge of scripting languages.

 to configure FCoE between the N9K-A switch and the FCF-A Nexus 9000 core switch with the given characteristics, the correct configuration would be the one that enables FCoE NPV mode, binds the interface to a port-channel, and allows only VSAN 20 on the trunk. Based on the provided CLI configurations, the correct answer would be Option D as it configures the switch in NPV mode and allows only VSAN 20

 The Cisco Integrated Management Controller (IMC) is a system management component built into Cisco UCS C-Series servers. When the IMC is upgraded, it disrupts the Keyboard, Video, Mouse (KVM) sessions that are used for remote server management. This is because the IMC upgrade process requires a reboot of the controller, which temporarily disconnects any active KVM sessions. However, it does not affect Cisco UCS Manager, SAN traffic, or data traffic, as these components operate independently of the IMC.

An advantage of NFS (Network File System) as compared to Fibre Channel is that NFS provides the dynamic allocation of storage capacity. This means that NFS allows the storage space to be allocated and released on demand, depending on the needs of the applications and users. NFS also enables the sharing of files and directories across different servers and clients, simplifying the management and access of data. Fibre Channel, on the other hand, is a protocol that provides high-speed and low-latency communication between storage devices and servers, but it requires fixed and pre-allocated storage capacity, which can lead to underutilization or overprovisioning of resources. Fibre Channel also requires dedicated hardware and cabling, which can increase the cost and complexity of the storage network.

The OPTIONS method is used in REST APIs to return the HTTP methods that the server supports for a specific URL. This can be useful for discovering what functionality a REST API endpoint supports.

The series of commands provided in the exhibit are part of the process to update and activate firmware on a Cisco UCS server adapter. The update firmware command is used to update the firmware, while the activate firmware command, combined with the set-startup-only option, schedules the activation of the firmware upon the next reboot of the adapter. This means that the new firmware will not be active immediately but will take effect after the adapter is rebooted, ensuring that the current operations are not disrupted.

References: For further details on firmware management commands and their effects in Cisco Data Center Core Technologies, you can refer to the Cisco UCS Manager Firmware Management Guide, which provides comprehensive instructions on updating and activating firmware on UCS components1. Additionally, the Cisco UCS Manager CLI Configuration Guide offers insights into the CLI commands used for managing firmware

 In a Cisco NX-OS environment, Ansible requires the NX-API to be enabled for HTTP/HTTPS protocol communication. NX-API is a REST-like API for NX-OS, providing a method for external applications to access the switch over HTTP/HTTPS, allowing for both CLI and simple object-based programming. This is necessary for Ansible to manage the device and execute automation tasks over these protocols.

Option C and E are the correct requirements when planning a Cisco HyperFlex All Flash standard cluster installation using three HX240c M5 servers. Option C states that if the Jumbo MTU option in the HyperFlex installer is enabled, then jumbo frames must also be enabled on the upstream switches, which is true for optimal performance and compatibility. Option E states that the servers must be discovered, unassociated, and connected to each fabric interconnect, which is also true for the cluster installation process. The other options are either false or not applicable for the scenario. References:

To deploy a Cisco UCS C-Series Server with a single VIC 1455 integrated into a Cisco UCS Manager cluster without fabric extenders, the system should be reset to factory default settings using Cisco IMC. After the reset, VIC ports 1 and 3 should be attached to the Fabric Interconnects. This process ensures that the server is recognized by the UCS Manager and can be managed accordingly. The VIC 1455 supports multiple Ethernet and Fiber Channel over Ethernet speeds, making it suitable for direct connection to Fabric Interconnects1.

Ansible is known for its agentless architecture, which means it does not require a software agent to be installed on the target nodes it manages. This contrasts with tools like Puppet and Chef, which typically require an agent to be installed on each node. Ansible uses SSH or WinRM to communicate with the nodes, making it simpler and more secure as it reduces the attack surface and the overhead of managing agents.

Cisco Data Center Network Manager (DCNM) is designed to help manage all NX-OS network deployments, which includes LAN fabrics, SAN fabrics, and IP Fabric for Media (IPFM) networking in the data center. DCNM provides prebuilt templates that can be used to customize fabric deployments, allowing for a more streamlined and efficient setup process. These templates include best-practice policy templates for Easy Fabric Mode and support for Python scripting for more complex policy templates, facilitating the customization and automation of fabric deployments.

The FCoE Initialization Protocol (FIP) uses a 24-bit FC-MAP and concatenates a 24-bit Fibre Channel ID to create a fabric-provided MAC address. This is part of the FIP’s role in establishing and maintaining the virtual links between an E-Node and the Fibre Channel Forwarder (FCF). The MAC address is essential for the E-Node to participate in FCoE communications within the fabric. The process ensures that each E-Node has a unique address on the Ethernet network, which encapsulates the Fibre Channel frames for transport. References := Cisco MDS 9000 Series FCoE Configuration Guide, Release 9.x

To migrate a Cisco UCS C-Series server from Cisco SingleConnect to direct integration mode with immediate discovery and auto-acknowledge policies, the steps in Option C are appropriate. These steps typically involve disconnecting the cables from the FEX, connecting them to the appliance ports on the fabric interconnect, and reacknowledging the server

To prevent loops from occurring accidentally on a switch interface designated for host connectivity, the best practice is to enable Spanning Tree Protocol (STP) protections. Option A, which includes the command spanning-tree guard loop, is the correct configuration to apply. This command enables Loop Guard, a feature that prevents alternate or root ports from becoming designated ports due to a failure that leads to a unidirectional link. If a port stops receiving Bridge Protocol Data Units (BPDUs), Loop Guard puts the port into an STP loop-inconsistent state, effectively preventing potential loops.

References := This information is aligned with the best practices for loop prevention as described in Cisco’s Data Center Core Technologies materials. For further details, refer to the study guide or source documents related to STP and its security features within the Cisco Data Center Core Technologies curriculum.

 NFS uses XDR (External Data Representation) as the communication method for requests between servers and clients. XDR is a standard format for encoding and decoding data that is exchanged between different systems. XDR allows NFS to handle data with different byte orders, word sizes, and data types. XDR is also used by ONC RPC, which is the underlying protocol for NFS. XDR ensures that the data is represented consistently and correctly across different platforms and architectures. References :=

 Option C is the correct attribute to use to assign the servers to different microsegments based on their VM names. By doing this, IT security can enforce policies that isolate production from development database servers existing in the same EPG and IP subnet. This can be achieved by using the microsegmentation feature of Cisco ACI, which allows granular control over the communication between endpoints within an EPG. References:

The network administrator role in Cisco UCS Manager is designed to allow configuration of network-related settings, which includes vHBAs, vNICs, and server port types. This role provides the necessary privileges to manage these components

 In an FCoE environment, the PAUSE mechanism is used to provide lossless behavior for Fibre Channel traffic over Ethernet. The PAUSE mechanism allows a receiver to send a PAUSE frame to a sender when its ingress buffer is full or close to full, instructing the sender to stop transmitting for a specified period of time. This prevents packet loss due to buffer overflow at the receiver. However, the PAUSE mechanism also introduces latency and jitter, which can affect the performance of FCoE applications. Therefore, the receiver must provision sufficient ingress buffer to accommodate the following two sets of data12:

• Frames that were processed and transmitted by the transmitter before the PAUSE frame left the sender. These frames are already on the wire and cannot be stopped by the PAUSE frame. They will arrive at the receiver and consume ingress buffer space.
• Frames that were sent on the link but not yet received. These frames are also on the wire and will arrive at the receiver after the PAUSE frame. They will also consume ingress buffer space.

The amount of ingress buffer required depends on the link speed, the link distance, and the PAUSE duration. The receiver must ensure that the ingress buffer can hold at least twice the link distance worth of data, plus some margin for safety3. For example, if the link speed is 10 Gbps, the link distance is 10 km, and the PAUSE duration is 100 microseconds, the receiver must have at least 25 MB of ingress buffer for each FCoE virtual lane4.

 For fabric redundancy in NPV mode on a Cisco MDS 9000 Series Switch, the engineer must connect the NPV devices to multiple upstream switches (A). This setup ensures that if one upstream switch fails, the NPV device can still reach the fabric through another upstream switch, maintaining fabric redundancy.

 To achieve fast reconvergence between directly connected switches in a data center using OSPFv2, two critical actions must be taken. First, setting low OSPF hello and DEAD timers can significantly reduce the time it takes for OSPF to detect a link failure and start the reconvergence process. This is because OSPF hello packets are used to maintain neighbor relationships, and the DEAD timer determines how long a router will wait without receiving a hello packet before declaring the neighbor down. By reducing these timers, OSPF can detect failures more quickly and initiate a faster reconvergence.

Second, enabling Bidirectional Forwarding Detection (BFD) for failure detection is essential. BFD is a network protocol that provides fast failure detection times for all media types, encapsulations, topologies, and routing protocols. By implementing BFD, OSPF can be notified of link failures almost immediately, allowing for a rapid response to changes in the network topology and ensuring minimal disruption to data flows2.

To meet the requirements of performing a backup and restore of the Cisco Nexus 5000 Series Switch configuration using UDP as the only protocol, the network engineer must follow these steps:

• Perform a startup-config backup to a TFTP server. The startup-config file contains the configuration that is applied when the switch boots up. To backup this file to a TFTP server, the engineer can use the copy startup-config tftp: command, and specify the IP address or hostname of the TFTP server and the destination filename. For example:

switch# copy startup-config tftp: Enter hostname for the tftp server: 10.10.10.10 Enter destination filename: backup-config

• Copy backup-config from the backup server to the running-config file. The running-config file contains the configuration that is currently active on the switch. To restore this file from the backup-config file on the TFTP server, the engineer can use the copy tftp: running-config command, and specify the IP address or hostname of the TFTP server and the source filename. For example:

switch# copy tftp: running-config Enter hostname for the tftp server: 10.10.10.10 Enter source filename: backup-config

These steps will allow the engineer to backup and restore the switch configuration using UDP as the only protocol, as TFTP is a UDP-based protocol. The backup-config file can be used when the current working configuration of the switch gets corrupted, as required by the goal. References :=

The configuration snippet in the exhibit shows that VSAN 100 is allowed on interface Ethernet1/12 with the command “switchport trunk allowed vsan 100”. This means option B, “Allow VSAN 100 on interface eth1/12”, is the correct answer. In Cisco Data Center Core Technologies, it’s essential to allow specific VSANs on an interface to enable traffic flow for those VSANs.References: Implementing and Operating Cisco Data Center Core Technologies (DCCOR) - Configuring FCoE

 The command rpm -Uhv is used to upgrade or install an RPM package on Linux-based systems. In the context of upgrading bash on a Cisco Nexus 9000 Series Switch, this command would be used to install the new bash package from the provided file path.

An advantage of streaming telemetry over SNMP is that it supports periodic push-based subscription messages. Streaming telemetry is a method of collecting and transporting network data from devices to a receiver, such as a collector or a dashboard. Streaming telemetry allows the devices to send data periodically or on-demand, based on a subscription model. The receiver can subscribe to specific data sets or events that it is interested in, and the device will push the data to the receiver as it becomes available. This reduces the overhead and latency of polling the device status using SNMP, and provides more granular and real-time visibility into the network state and performance. References :=

 ARP suppression is a feature used in VXLAN/EVPN environments to optimize ARP responses and reduce unnecessary ARP broadcasts across the fabric. When ARP suppression is enabled, the local VTEP (VXLAN Tunnel Endpoint) can respond to ARP requests for known IP-to-MAC address bindings, which are learned via the BGP EVPN control plane. This prevents the need for ARP broadcasts to be sent across the entire VXLAN fabric, thus optimizing the ARP response mechanism and reducing broadcast traffic1.

The configuration shown in the exhibit is related to the infrastructure firmware upgrade process in a Cisco UCS environment. When an infrastructure firmware upgrade is initiated, it typically includes updates to various components such as the adapters and the BIOS. The adapters require firmware updates to ensure compatibility with new features and fixes, while the BIOS update is crucial for system stability and to support new hardware and software enhancements. The infrastructure firmware package, also known as the ‘A bundle’, contains the necessary firmware images for these components1.

Port security on Cisco MDS 9000 series Switches is a feature that allows administrators to restrict access to the switch ports to specific devices. When port security is enabled, it does not automatically add currently logged-in devices to the device database; they must be added manually. This ensures that only authorized devices can access the network, enhancing the security of the SAN environment.

References: The Cisco MDS 9000 Series Security Configuration Guide provides detailed information on the configuration and behavior of port security, including the requirement for manual addition of devices to the database

The In-Service Software Upgrade (ISSU) feature on Cisco Nexus 9000 Series Switches supports nondisruptive upgrades via nonstop forwarding. This allows the switch to continue forwarding traffic while the system software is being upgraded, thereby minimizing downtime and maintaining continuous network service

 To configure a Fibre Channel device alias named TEST for a device attached to port fc1/9 on a Cisco Nexus Series Switch, the correct command set is found in Option A. The commands should be entered in configuration mode, starting with accessing the device-alias database, creating the device-alias named TEST with the specified pwwn, and committing the changes to the database123.

References := The process for configuring a Fibre Channel device alias on a Cisco Nexus Series Switch is detailed in the Cisco Nexus 9000 Series NX-OS SAN Switching Configuration Guide and other Cisco documentation related to SAN switching and device aliases

To ensure that the Cisco Nexus 7000 series switches are the primary devices for LACP, the configuration must use the lacp system-priority command to assign a lower priority value to the switches. This command determines which device is the active partner in an LACP negotiation. The lower the priority value, the higher the preference. In option A, the switches have a priority value of 1, which is the lowest possible value and the highest preference. Therefore, option A is the correct configuration to make the switches the primary devices for LACP.

References := The explanation is based on the official Cisco documentation on Configuring Link Aggregation Control Protocol (LACP) 1, specifically the section on Configuring LACP System Priority.

When SVR-A in EPG-A/BD-A cannot reach SVR-B in EPG-B/BD-B, it’s crucial to ensure that a contract exists between EPG-A and EPG-B that permits the traffic (Option A). Contracts in Cisco ACI act as a policy framework that dictates the types of traffic allowed between EPGs. Without an appropriate contract, traffic will not be allowed to pass between these entities.

Additionally, verifying that SVR-B is learned as an endpoint in EPG-B from Node-112 (Option C) is essential. Endpoint learning within ACI is a process where the leaf switch learns about the endpoints connected to it. If Node-112 has not learned SVR-B as an endpoint, it will not be able to forward traffic to it, resulting in connectivity issues.

References: = For more information on contracts and endpoint learning, refer to the Cisco ACI documentation on the Cisco official website. Specifically, look into sections detailing ACI contracts and endpoint learning processes.

When a Cisco Nexus 9000 series switch encounters a startup configuration corruption, the recovery process involves clearing the current configuration, restarting the device, and then restoring the configuration from a previously saved file. The correct sequence is to first clear the configuration to prevent the corrupted startup configuration from loading upon restart. After restarting the device, the previously saved configuration file should be copied to the running configuration. Finally, to ensure the switch starts with the correct configuration in future restarts, the running configuration should be saved to the startup configuration.

References: The recovery process is detailed in the Cisco community documentation, where it outlines the steps for recovering the configuration in UCS by importing the configuration from a previously saved location

Option B is the correct answer because it meets both requirements stated in the question. The configuration permits SSH connectivity from a jump host with an IP address of 10.10.10.10/24 and allows all switches to connect via SSH to other devices from the subnet of 10.20.20.0/24.

In this option, the access list acl-1 is configured to permit TCP traffic from host 10.10.10.10/32 (the jump host) on any port, and access list acl-2 is configured to permit TCP traffic from subnet 10.20.20.0/24 on any port.

The ‘line vty’ configuration applies these access lists for inbound (in) and outbound (out) SSH sessions respectively, ensuring that only the specified source IP addresses are allowed for remote SSH management connectivity1.

When you run the install commit  command on a Cisco Nexus 9000 Series Switch, it schedules the new package to be used after the next reboot of the switch. This means that the current running configuration isn’t immediately affected by the new package, but it will be incorporated once the switch is restarted.

 The ‘iqn_pool’ attribute in Ansible is used to apply iSCSI initiator identifiers to all iSCSI vNICs for service profiles derived from a service template. This ensures that each iSCSI vNIC has a unique identifier for storage communication2

 In a VXLAN data center fabric, inter-VNI communication requires mapping Layer 2 (L2) VLANs to their respective L2 VNIs and associating them with the correct Layer 3 (L3) VNI that corresponds to the VRF. In this case, VLAN 100 is mapped to L2 VNI 2020, and for inter-VNI routing to occur, it must be associated with an L3 VNI that corresponds to the VRF, which is Test_Telco_VRF to L3 VNI 1010. References: For more detailed information, you can refer to the Cisco Programmable Fabric with VXLAN BGP EVPN Configuration Guide1 and the Data Center VXLAN EVPN guide
