To verify failover in a two-node ONTAP configuration, you must confirm both cluster-level HA state (for two-node clusters) and storage failover state (takeover/giveback readiness) for the HA pair.

The commandcluster ha showis used to verify the cluster HA status, which is especially relevant in two-node clusters where cluster HA can affect whether services remain available when one node is halted/rebooted. ONTAP documentation notes behaviors specific to two-node clusters and cluster HA, including the importance of proper HA configuration to avoid both nodes stopping data service under certain halt/reboot conditions.

The commandstorage failover showis the primary command to verify HA pair readiness, showing takeover/giveback capability, partner connectivity, and status indicators needed to confirm that storage failover is configured correctly.

Option C (cluster ring show) is a cluster database/ring status diagnostic command; while it can be useful in troubleshooting quorum or RDB-related issues, it is not the standard command pair for verifying HA failover configuration correctness after installation. Option D (storage failover show-takeover) is not the common baseline verification command cited for confirming general failover configuration; it is more takeover-output oriented rather than providing the full readiness overview that storage failover show provides.

Therefore, the two commands that accomplish correct failover verification in this scenario areA. cluster ha showandB. storage failover show.

Within the ONTAP SAN solution assessment domain, NetApp emphasizes the creation of accurate and reusable documentation immediately after system installation. One of the supported tools for this purpose is NetAppDocs, which is designed to collect system configuration data and generate standardized inventory and design documentation. According to NetApp Storage Installation concepts and objectives, inventory reports must be produced in formats that support both technical review and customer handoff, while remaining editable and auditable.

NetAppDocs is explicitly described in NetApp documentation as supporting Microsoft Word, Microsoft Excel, and PDF outputs for inventory-style reports. These formats align with operational best practices defined in installation and assessment workflows. Word (.docx) files are used to present structured design narratives and annotated configuration details. Excel (.xlsx) files are used to present tabular inventory data such as controllers, disk shelves, ports, adapters, WWPNs, and LIF assignments, which are critical for SAN assessment and future expansion planning. PDF (.pdf) files are used as finalized, non-editable deliverables suitable for compliance records, customer signoff, and archival purposes.

Formats such as HTML and PostScript (.ps) are not identified in NetApp Storage Installation objectives as supported NetAppDocs inventory outputs. These formats do not align with NetApp’s standardized documentation deliverables and are not referenced in official installation or assessment documentation. As a result, they are excluded.

From a SAN-focused assessment perspective, the ability to generate Word, Excel, and PDF reports ensures consistency across deployment teams, simplifies validation of ONTAP SAN configurations, and supports accurate lifecycle documentation. These formats are repeatedly reinforced in NetApp installation guidance as the approved and supported inventory report outputs.

Therefore, the correct answers are A (.docx), C (.pdf), and E (.xlsx), as they are the only formats verified and supported for NetAppDocs inventory reporting within NetApp Storage Installation concepts and domains provided by NetApp.

ONTAP 9.x defaults toRAID-DPfor SATA, NL-SAS, SAS, and SSD aggregates unless specific conditions require RAID-TEC. RAID-DP provides double-parity protection, allowing the system to withstand two simultaneous disk failures, which is essential for large-capacity SATA drives such as 10 TB disks.

RAID-TEC is reserved for very large aggregates with higher disk counts and is not the default. RAID4 and RAID1 are not used as default aggregate RAID types in ONTAP 9.

Therefore, the aggregate will be created withRAID-DP.

During cluster setup, nodes usecluster interconnect LIFs, which are automatically assignedlink-local IP addresses in the 169.254.x.x range. Management IP addresses (192.168.x.x) are not used for node join operations.

The address169.254.212.198corresponds to node02’s cluster LIF and would therefore be used to join the cluster.

AFF A250 systems use aconverged networking design, where the same physical ports are used for bothcluster interconnect traffic and HA interconnect traffic. This differs from older platforms that used dedicated HA interconnect ports.

The NetApp CN1610 switches only support10GbE, which is insufficient for AFF A250 systems. AFF A250 platforms require25GbE-capable cluster switchesto support both cluster and HA interconnect traffic.

Because the cluster ports are operational, the nodes can join the cluster. However, the HA interconnect traffic cannot be established due to insufficient switch capability, which explains why the NVRAM log cannot synchronize and the HA partner is unreachable.

Therefore:

The AFF A250requires switches with 25GbE port support

The AFF A250uses the same ports for cluster and HA interconnect

Statements involving 40GbE or separate HA ports are incorrect.

The correct answers areC and D.

NetApp best practices allow mixing NAS protocols (NFS and CIFS) or SAN protocols (FCP and iSCSI) within the same SVM, but not mixing NAS and SAN.

After completing the initial configuration of a multi-node ONTAP cluster and its cluster interconnect switches, NetApp installation best practices require enabling proactive monitoring of the cluster network. TheCluster Switch Health Monitor (CSHM)is the ONTAP feature designed specifically for this purpose.

CSHM continuously monitors the health of supported cluster switches by collecting information such as switch configuration, port status, firmware versions, cabling, and error conditions. It validates this information against NetApp-supported configurations and best practices. When deviations or risks are detected, CSHM generates alerts and EMS messages that allow administrators to take corrective action before cluster communication is affected.

Cluster switch logging alone does not provide health analysis or proactive validation; it only records switch events. IPv6 is not required or recommended for cluster interconnect networks in standard ONTAP installations. Data Center Bridging (DCB) is used for specific Ethernet storage protocols and is not applicable to ONTAP cluster interconnect networks.

Therefore, enabling thecluster switch health monitoris the correct and required post-installation step.

NetApp hardware installation documentation strictly definessupported cable types and distancesfor Ethernet connectivity. For 40GbE connections using QSFP+ interfaces, NetApp supports both copper and optical cabling, each with specific distance limitations.

The exhibit shows supported copper cable options, including10-meter NetApp-supported copper cables, which exceed the current seven-meter requirement. Installing these supported cables is a valid and compliant solution.

Alternatively, the customer can change the requirement tooptical cables, which support significantly longer distances and are fully supported for AFF A400 40GbE connectivity. Optical cables are commonly used when distance exceeds passive copper limitations.

Relocating equipment is not required when supported cabling options exist. Changing “Ethernet cable requirements” generically is not a valid technical action.

Therefore, the correct answers areB and D.

NetApp installation rules prohibit mixingNSE and non-NSE drives within the same stack. While the AFF A300 supports both encrypted and non-encrypted drives, they must be physically separated into different stacks.

Licensing NSE alone does not allow mixing encrypted and unencrypted drives in the same stack. The correct approach is tocreate a new stackspecifically for the NSE drives.

Therefore, the correct answer isB.

When expanding an ONTAP cluster by adding new nodes or HA pairs,intercluster LIFsare required to enable secure communication between clusters or nodes during join and expansion workflows. Intercluster LIFs provide IP-based connectivity used for cluster peering, node addition, and replication setup.

Cluster management LIFs are used for administrative access, node management LIFs provide per-node management access, and data LIFs are used for client I/O. None of these LIF types support the inter-node communication required during cluster expansion.

Therefore, anintercluster LIFis required.

Before removing a node from an ONTAP cluster, NetApp installation procedures require several validation steps to ensure cluster quorum and availability are preserved. The exhibit shows cluster ring information indicating quorum status and master node assignment.

First,high availability must be confirmed. The node being removed must have an HA partner capable of taking over resources. This ensures nondisruptive operation during and after node removal, which is a mandatory prerequisite for the cluster remove-node command.

Second, the node must be marked asineligibleusing the cluster modify -eligibility false command. This prevents ONTAP from attempting to assign cluster responsibilities or data ownership to the node while it is being removed. This step is explicitly required in NetApp removal workflows.

MovingEpsilon(the quorum tie-breaker) to the node being removed would be incorrect and dangerous, as Epsilon must remain on a stable node to maintain cluster quorum. Additionally, the cluster does not automatically re-elect a new master simply because a node is removed; mastership is determined before removal.

Therefore, the correct statements areA and B.

Secure multitenancy in ONTAP requires complete separation of network traffic, routing tables, and IP addressing.IPspacesprovide this level of isolation by creating independent network stacks within a single ONTAP cluster.

Failover groups, VLANs, and broadcast domains organize network paths but do not isolate routing domains. Only IPspaces ensure tenants cannot access each other’s network traffic.

Thus,IPspacesenable secure multitenancy.

In ONTAP, LIF failover target selection is controlled byfailover groupsandfailover policies. A key installation and validation concept is that ONTAP uses broadcast domains to simplify and automate failover-group membership. Specifically, ONTAP documents that when you create a broadcast domain, ONTAP automatically creates a failover group with the same name and manages it so that as ports are added or removed from the broadcast domain, they are also added or removed from the associated failover group.

Because of this coupling, if a LIF “moves to a port that is not expected,” the most direct and common cause is that thebroadcast domain contains ports that do not belong there(or ports that should be in a different broadcast domain/IPspace). When the original port goes down (for example, because you disabled the connected switch), ONTAP looks for eligible failover targets in the LIF’s assigned failover group. If the broadcast domain was defined too broadly or incorrectly, the failover group will also be too broad, and ONTAP may pick a port that appears valid per configuration but is “unexpected” from the design intent.

Option C (“There are no online ports within the same failover group”) would more commonly result inno valid failover target(and therefore an outage) rather than a clean migration to an unexpected port; ONTAP even warns that without a valid target, an outage occurs during failover verification. Option A is too generic and does not specifically explain why adifferentport becomes a valid target. Option D is not a typical ONTAP networking root cause for LIF migration behavior.

Therefore, the behavior is best explained by an incorrectly configured broadcast domain.

The cluster ping-cluster command is specifically designed to testinter-node cluster network connectivity, includinglatency, packet loss, and throughputbetween cluster nodes. This command generates synthetic traffic over the cluster interconnect and measures performance characteristics that directly affect cluster health and stability.

The command is commonly used duringpost-installation validation, cluster expansion, and troubleshooting scenarios involving cluster network performance. It provides insight into whether the cluster interconnect is operating within expected parameters.

Other commands listed do not provide this functionality. QoS workload statistics focus on application-level performance, network test-path validates reachability for LIF failover paths, and statistics node show reports internal node counters rather than inter-node network performance.

Therefore, the correct answer isB.

Within the ONTAP SAN implementation and configuration domain,automatic port placementis a key installation feature designed to simplify initial network setup during cluster deployment. In ONTAP 9.8, when controller data ports are discovered, ONTAP automatically analyzes physical port connectivity, speed, and role, and assigns those ports to appropriatebroadcast domainsandsubnets.

Broadcast domains define Layer 2 boundaries and group ports that share the same network reachability. During installation, ONTAP automatically creates and assigns broadcast domains based on detected network topology and intended port usage. This behavior is explicitly described in NetApp installation objectives as part of reducing manual network configuration during initial setup.

Subnets are also automatically created and associated when automatic port placement is enabled. ONTAP uses subnets to manage pools of IP addresses for data LIF creation. By automatically configuring subnets, ONTAP enables rapid deployment of NAS and SAN data LIFs without requiring administrators to manually define IP address ranges during installation.

By contrast,routesare not automatically configured by automatic port placement. Routes must be explicitly defined by the administrator to control Layer 3 traffic flow between networks. Similarly,IPspacesare logical network containers that must be deliberately designed and created based on multi-tenancy or isolation requirements. IPspaces are never automatically created by ONTAP during installation because they have architectural implications that require administrator intent.

Therefore, the two ONTAP network settings that are automatically configured by automatic port placement arebroadcast domainsandsubnets, makingC and Dthe correct answers.

When VLAN tagging is used, data LIFs are created on VLAN interfaces, not physical ports. Because multimode LACP is configured on port a0a, the correct VLAN interface is a0a-100.

Verifying interoperability between ONTAP versions, storage platforms, host operating systems, protocols, and host utilities is a mandatory step in NetApp solution assessment and installation planning. TheInteroperability Matrix Tool (IMT)is the authoritative NetApp resource used to confirm whether a specific combination of components is supported.

In this scenario, the customer needs to verify thatONTAP 9.8is supported withWindows Server 2016on an AFF ASA A700 system. IMT allows administrators to search by storage OS version, platform model, host OS, protocol (iSCSI, FC, NVMe), and host utilities to ensure the configuration is supported.

ONTAP System Manager is used for system administration, not supportability validation. Active IQ Unified Manager focuses on monitoring and performance. Active IQ OneCollect is used for data collection, not compatibility verification.

Therefore, the correct tool is theInteroperability Matrix Tool.

The customer’s environment uses aCisco MDSSAN fabric, so a Cisco-focused management/visibility tool is the most direct way to gain insight into the fabric’s configuration, health, zoning state, and operational status.Cisco Data Center Network Manager (DCNM)is a Cisco tool designed for managing Cisco SAN (including MDS) and therefore is the correct selection for Cisco fabric configuration insight.

From a NetApp installation and assessment perspective, the second tool that provides valuable insight—especially in the context of deploying NetApp storage into an existing fabric—isActive IQ Config Advisor. Config Advisor is used to validate installation-related configuration and cabling and to detect configuration issues across the environment, including SAN connectivity/cabling checks from the NetApp side. While it is not a Cisco fabric manager, it is the NetApp tool used during installation and verification phases to identify configuration and connection problems that affect successful deployment into a SAN environment (for example, incorrect connectivity patterns or misconfigurations that would impact host/storage access).

Option A (Brocade SAN Health) is purpose-built for Brocade environments and does not match “Cisco MDS fabric configuration.” Option C (Active IQ) focuses on NetApp system health, telemetry, and risks for NetApp arrays rather than providing direct insight into a Cisco MDS fabric configuration.

Therefore, the two tools that best satisfy “insight into their existing Cisco MDS fabric configuration” in the context of deploying NetApp SAN storage areB. Cisco DCNM(Cisco-side fabric visibility) andD. Active IQ Config Advisor(NetApp-side installation validation and connectivity/configuration checks relevant to the fabric integration).

A Service Event Report (SER) is used to document installation, maintenance, or corrective actions performed on NetApp systems. Thenode serial numberis the primary identifier used to associate the report with specific hardware.

Other identifiers such as case ID, project number, or sales order number are supplementary and may not always exist at the time the SER is created.

Therefore, the correct answer isC (the node serial number).

On AFF A220 systems, porte0Mis the dedicatedmanagement Ethernet portused for node management. This port is physically separate from data and cluster ports and is typically a 1GbE RJ-45 interface. In the exhibit, number1points to this dedicated management port.

ONTAP assigns the logical namee0Mautomatically to this physical interface, and it is reserved exclusively for management traffic. Administrators use e0M to configure node management LIFs, access the Service Processor (SP/BMC), and perform out-of-band management tasks.

Other numbered ports in the exhibit represent data, cluster, or console-related interfaces and cannot be used as e0M. Because ONTAP maps e0M to a fixed physical location on AFF A220 controllers, the correct answer is1.

Default failover groups are defined bybroadcast domains. Therefore, the LIF fails over to any operational port in the broadcast domain.

NS224 shelves are Ethernet-attached and connect through supported Ethernet switches. Additional capacity can be added either by attaching new NS224 shelves to the existing Ethernet fabric or by scaling out the cluster with additional AFF A400 nodes. NS224 shelves cannot be daisy-chained directly to other NS224 shelves, and dedicated storage switches are not required.

Service Event Reports require standardized installation and configuration data.NetAppDocsgenerates structured output reports specifically designed for SER creation, including hardware, cabling, and configuration details. Other tools do not produce SER-formatted documentation.

Understanding hardware components is a core requirement within ONTAP SAN concepts. The exhibit highlights several key components on a FAS9000 system that are essential to system operation and high availability.

The large central components shown are the controllers, which house the CPUs, memory, and network interfaces responsible for data processing and cluster operations. Adjacent to the controllers are the NVRAM modules, which are critical for write caching and data integrity. NVRAM ensures that incoming write operations are safely logged and protected in the event of power loss or controller failover.

The exhibit also highlights the serial ports, which are used for low-level system access during installation, troubleshooting, or recovery scenarios. Serial ports are especially important during initial setup or when network access is unavailable.

Finally, the highlighted FlashCache modules provide read caching functionality. FlashCache accelerates read-intensive workloads by caching frequently accessed data on flash memory, improving overall system performance.

Other options are incorrect because they either include components not highlighted in the exhibit (such as power supplies or USB ports) or misidentify the flash modules. Therefore, the correct set of components shown in the exhibit is NVRAM-Module, Controller, Serial-Port, FlashCache-Module.

Broadcom BES-53248 cluster interconnect switches require aReference Configuration File (RCF)to define supported port roles, speeds, breakout behavior, ISLs, and node-facing ports. By default, only a subset of ports is enabled for cluster connectivity. Ports0/17 through 0/20are not active for node connections unless explicitly configured by the correct RCF.

When new controllers are cabled to ports that are not enabled or correctly configured for cluster interconnect traffic, the ONTAP nodes cannot establish cluster LIF communication and therefore cannot join the cluster. Installing the correctRCFconfigures these ports with the required VLANs, MTU, flow control, and speed settings so that cluster traffic can pass.

A license file is not required for basic cluster interconnect functionality. The Cluster Switch Health Monitor (CSHM) configuration file enables monitoring, not port functionality. Rebooting controllers does not resolve switch-side configuration issues.

Therefore, installing thereference configuration fileis the required corrective action.

This question tests installation cabling constraints and supported cabling media for SAS connectivity. The key issue is distance: the customer wants to use20-meter copper SAS cablesbetween a controller and a shelf that are installed in separate rows.

NetApp hardware cabling guidance indicates that when long distance SAS connectivity is required, the supported approach is to useSAS optical cabling(for applicable platforms and shelf/IOM combinations). The ONTAP hardware systems documentation describes “mini-SAS HD SAS optical cable rules,” noting that optical AOC SAS cables are available in lengths up to50 metersfor controller-to-stack and shelf-to-shelf connections in supported configurations. This highlights a critical installation principle: long SAS runs are addressed withoptical, not copper.

The documentation also establishes that SAS cabling within a stack must be consistent (all copper or all optical) and that mixed approaches have specific constraints. While the excerpt emphasizes optical rules (because optical is the mechanism for long distance), it implicitly reinforces that copper has practical distance limitations and is not the long-distance solution.

Therefore, if the customer insists on copper SAS, the correct guidance is thatthe controller and disk shelf must be closer togetherto remain within supported copper SAS distance limits and to ensure signal integrity and supported operation. Option B is incorrect because simply “obtaining” 20-meter copper SAS cables does not make the configuration supported. Option D is incorrect because Ethernet adapters do not replace SAS for shelf connectivity. Option A is nonsensical in this context because SAS shelf connectivity cannot be replaced by a “wireless adapter” as a supported installation practice.

Thus, the correct answer isC: if copper cables are to be used, the devices must be closer together; otherwise the supported solution is to use a supported SAS optical approach.
