Nutanix NCA-6.10 Dumps

Non-migratable VMs in a Nutanix cluster typically include those with attached Volume Groups. This is because such VMs leverage direct-attached storage via iSCSI, which ties them to a specific host, preventing live migration to another host. Volume Groups provide block storage to applications, and the iSCSI protocol does not support live migration of such connections.

Here's a breakdown of the options:

A. VMs without NGT:Nutanix Guest Tools (NGT) are used for guest-level integration but do not affect VM migratability.

B. VMs marked as an Agent:This setting does not inherently make VMs non-migratable. It primarily affects roles and tasks within certain configurations.

C. Memory Overcommitted:While memory overcommitment can affect performance, it does not make VMs non-migratable. Nutanix AHV handles memory allocation dynamically.

D. VMs with attached Volume Groups:Correct answer, as the iSCSI connections used by Volume Groups are host-specific and cannot migrate seamlessly.

The correct answer isC. 4

Erasure Coding (EC-X)in Nutanix is a data efficiency feature that replaces multiple replicas with parity data to reduce storage overhead while still protecting against failures. Theminimum node requirementfor enabling Erasure Coding is4 nodes, due to the need to distribute data and parity across multiple failure domains.

Details:

RF2 with EC-Xrequires at least4 nodes.

RF3 with EC-Xrequiresat least 6 or 8 nodes, depending on configuration.

Prism UI Navigation Path:

Storage > Storage Containers > Enable EC-X

Official Reference:

Nutanix Bible – Erasure Coding Section

Nutanix Storage Admin Guide

Excerpt: “A minimum of 4 nodes is required in a Nutanix cluster to enable Erasure Coding (EC-X) with RF2.”

To create a VM-VM Anti-Affinity Policy ensuring VMs are not placed on the same hypervisor,Prism Centralis required. Anti-affinity policies are cluster-wide configurations managed through Prism Central’s policy-based interface, enabling placement rules to distribute workloads effectively.

Steps:

Navigate toPrism Central > Policies.

Create a new Anti-Affinity Policy.

Select the VMs and configure the policy to ensure separation.

APriority 1 (P1)case guarantees an8-hour response timefor customers with Production Support. P1 cases are designated for critical issues that severely impact business operations or cause a complete system outage, requiring immediate attention from Nutanix Support.

Other priorities:

P2: High-impact issues but not critical, response time varies.

P3: Medium impact, typically non-urgent issues.

P4: Low priority, general inquiries or minor issues.

The correct answer isA. br0.

InAHV (Acropolis Hypervisor),br0is thedefault native Linux bridgecreated on each hypervisor host. It is used for VM traffic and external communication. AHV leveragesOpen vSwitch (OVS)to manage virtual networking, but the bridge is exposed as br0 in the host's network configuration.

Key points:

br0connects VM virtual NICs (vNICs) to the physical network via the host's uplinks.

It is pre-configured during Foundation or cluster deployment.

virbr0is typical in KVM environments but isnot usedin AHV.

Official Reference:

Nutanix AHV Networking Guide

Nutanix KB #2027 – AHV Host Networking

Excerpt: “AHV uses br0 as the default bridge on the host, configured by Open vSwitch for guest VM networking.”

Answer: A

The correct answer isC. Mount and install the VirtIO drivers.

When installingWindows OSon aNutanix AHV VM, the default virtual disk controller uses theVirtIO interface, which isnot natively supported by Windows installation media. As a result, during the OS installation, the virtual disk will not appear unless theVirtIO drivers are manually provided.

Required Steps:

Attach theVirtIO ISOto the VM.

During the Windows installation, click“Load Driver”.

Browse to the mountedVirtIO ISOand select the appropriate storage driver.

Once loaded, the installer will detect the virtual disk.

Clarifications:

A (Add a second disk):Irrelevant; the issue is driver recognition, not disk quantity.

B (Enable Turbo Mode):Related to performance, not disk detection.

D (Install Nutanix Guest Tools):Doneafter OS installation, not before or during.

Prism UI Navigation Path:

VM > Edit > CD-ROM > Mount ISO → Select VirtIO ISO

Official Reference:

Nutanix AHV Administration Guide – Creating Windows VMs

Nutanix KB #5967 – AHV: Windows Installation on VirtIO

Excerpt: “If the disk is not detected during Windows installation, the VirtIO ISO must be mounted and the appropriate storage controller driver manually installed.”

The correct answer isC. Pulse.

Pulseis Nutanix's integrated telemetry and support communication service. WhenPulse is enabled, it provides automatic delivery and updates of Nutanix software tools, including theNutanix Cluster Check (NCC)utility. This allows the system toautomatically download and apply newer versions of NCCwithout requiring manual intervention.

Clarifications:

A (LCM HTTPS):Refers to LCM transport protocol, unrelated to NCC updates.

B (Daily Digest):A reporting feature, not an update mechanism.

D (LCM Auto Inventory):Related to firmware/software inventory, not to NCC or system utilities.

Prism UI Navigation Path:

Settings > Pulse > Enable Pulse

Official Reference:

Nutanix NCC Administration Guide

Nutanix Support FAQ

Excerpt: “NCC auto-update is available when Pulse is enabled, allowing Nutanix to deliver updated NCC versions directly to the cluster.”

Answer: C

To rerun only the health checks that previously failed or issued warnings, the administrator can select theOnly Failed and Warning Checksoption in Prism Element. This targeted approach helps verify that resolved issues have been addressed without rerunning all checks unnecessarily.

Steps:

Navigate toPrism Element > Health > NCC Checks.

Filter forOnly Failed and Warning Checksand rerun them.

Other options:

A. Run LCM Pre-Upgrade: Runs pre-upgrade checks, not related to health check validation.

B. Runncc health_checks run_all: Executes all checks, not just failed ones.

C. Select Run Check for each check worked: Requires manual execution for each check.

Log files requested by Nutanix Support can be collected from theSettingsdashboard in Prism Element. Within Settings, administrators can access the "Export Logs" or "Support" section to collect and upload diagnostic data directly to Nutanix Support.

A. Settings:Correct, as logs are collected and uploaded via the Settings dashboard.

B. Alerts:Incorrect, as Alerts display system issues but do not provide log collection options.

C. Health:Incorrect, as the Health dashboard focuses on system checks and cluster status.

D. Analysis:Incorrect, as the Analysis dashboard provides performance monitoring, not log collection.

When configuring a physical network switch in Prism Element,SNMP Configurationis required to enable monitoring and communication between the Nutanix cluster and the network switch. SNMP (Simple Network Management Protocol) is used to gather metrics and detect issues such as link failures or performance bottlenecks, ensuring the cluster operates efficiently with the physical network infrastructure.

To prevent password access to the CVM for both thenutanixandadminuser accounts,Cluster Lockdownshould be enabled. Cluster Lockdown restricts SSH access to the Controller VM (CVM), effectively disabling password-based logins for enhanced security. Access is then managed through more secure means, such as console access or specific tools like Nutanix Support.

A. Cluster Lockdown:Correct, as this prevents SSH-based access to the CVM.

B. STIG:Incorrect, as STIG (Security Technical Implementation Guide) focuses on broader compliance measures.

C. RBAC Policy on PC:Incorrect, as RBAC (Role-Based Access Control) controls Prism Central permissions, not CVM access.

D. Data-at-Rest Encryption:Incorrect, as this secures stored data, not access credentials.

In Prism Central, theImagessection within the Compute and Storage tab is used to upload ISO files, including Windows installation ISOs. Once uploaded, these images can be used to create or install VMs across clusters managed by Prism Central.

A. Catalog Items:Incorrect, as this is used to manage preconfigured application templates.

B. Templates:Incorrect, as this is used for VM templates, not ISO uploads.

C. Images:Correct, as it allows uploading and managing ISO and disk images.

D. OVAs:Incorrect, as this pertains to importing virtual appliances, not ISO files.

To create a VM template from an existing VM in Nutanix, the VM must be powered off. This ensures that the template is consistent and does not include any transient data or activity from the VM. Once the VM is powered off, the administrator can use the Prism UI to take a snapshot and designate it as a template.

A. Sysprep or Cloud-init script:These are optional for post-deployment configuration, not mandatory for creating a template.

B. The VM is powered on:This is incorrect, as the VM must be powered off.

C. Windows OS is installed:The OS type is irrelevant for creating a template.

D. The VM is powered off:Correct, as creating a template requires the VM to be in a powered-off state.

The correct answer isB. Acropolis Dynamic Scheduling (ADS).

Acropolis Dynamic Scheduling (ADS)is a core component in Nutanix AOS responsible for:

Monitoring real-time resource utilization.

Identifying hotspotssuch as CPU/memory/storage contention.

Automatically initiatingVM migration (live)tobalance workloadsacross hosts in the cluster.

Clarification of Other Options:

A. Cerebro:Responsible for replication, snapshots, and consistency.

C. Chronos:Manages scheduling of distributed tasks (not resource balancing).

D. CVM:Hosts the AOS services butdoes not perform workload balancing.

Official Reference:

Nutanix Bible – Acropolis Dynamic Scheduling

Nutanix AOS Architecture Guide

Excerpt: “ADS monitors resource utilization across the cluster and performs live VM migrations to mitigate hotspots and balance performance.”

Nutanix Metro Availability provides the best Recovery Time Objective (RTO) because it enables synchronous replication between two sites. In the event of a failure at one site, VMs can be instantly restarted on the other site with minimal disruption. This setup ensures zero data loss and near-instantaneous recovery.

A. Async:Provides high RPO (Recovery Point Objective) but has a longer RTO compared to synchronous replication methods.

B. Availability Zone:This term refers to a general site setup, not specific to recovery objectives.

C. Metro Availability:Correct, as it uses synchronous replication for near-zero RTO.

D. NearSync:Provides better RPO than Async but does not match the RTO of Metro Availability.

The correct answer isB. From the My Nutanix Licensing Summary page, click Manage Licenses and follow the specified process.

WithNutanix Cloud Platform (NCP) Package Licensing, licensing is centrally managed through theMy Nutanix Portal, where customers can:

View license entitlements.

Allocate or assign licenses to clusters.

Download license files for upload via Prism Central or Prism Element.

The entry point for license assignment begins at theLicensing Summary page on the My Nutanix Portal.

Clarification of Other Options:

A and D:Prism Central and Prism Element are used touploadlicenses, not assign or generate them.

C:“Nutanix Portal” is a vague reference; the correct term is “My Nutanix”.

Official Reference:

Nutanix Licensing Guide – Cloud Platform Licensing

Excerpt: “Log in to My Nutanix > Licensing Summary > Manage Licenses to assign and manage licenses for your clusters.”

Answer: B

The default admin session logout time in Nutanix is15 minutes. If no activity is detected within this time, the session is automatically logged out for security reasons. This timeout can be adjusted in the system settings if needed, depending on organizational requirements.

The correct answer isB. Create an RF1 storage container.

In Nutanix architecture,Replication Factor (RF)is set at thestorage container levelto optimize redundancy and performance for specific workloads. When an application hasits own internal redundancy, such as database clustering or distributed file systems, the administrator may choose toreduce Nutanix’s redundancy to RF1, which stores onlyone copy of datain the cluster. This reduces overhead and maximizes usable capacity, but isnot fault-tolerantat the Nutanix level.

Key clarifications:

RF1 is not enabled by default.Nutanix clusters default toRF2 or RF3depending on the configuration and number of nodes.

RF1 must beexplicitly setwhen creating a storage container.

There isno separate "enable RF1"setting outside of selecting RF1 at container creation; once selected, it applies directly.

Prism UI Navigation Path:

Storage > Storage Containers > Create Storage Container > Data Redundancy Level → Select "RF1"

Official Reference:

Nutanix Bible – Storage Layer and RF Explanation

Nutanix Storage Administration Guide – "Creating Containers with Specific Replication Factor"

Excerpt: "RF1 is typically used for workloads with native redundancy. It must be selected explicitly during container creation."

Conclusion:Onlyoption Baccurately reflects this process.

Answer: B

Life Cycle Management (LCM) in Nutanix is a feature designed tosimplify software and firmware upgradesacross the entire cluster. LCM automates and orchestrates upgrades for components like BIOS, hypervisors, firmware, and Nutanix software, ensuring that the cluster remains up-to-date with minimal manual intervention.

A. To optimize server performance:Incorrect, as LCM focuses on updates, not performance optimization.

B. To manage network configurations:Incorrect, as LCM is unrelated to network configuration management.

C. To simplify software and firmware upgrades:Correct, as LCM is specifically designed for this purpose.

D. To automate application deployment:Incorrect, as LCM does not handle application deployment.

When multiple alert policies are applied to an entity, Nutanix uses a hierarchical approach. Policies applied toan entity type within a categorytake precedence. For example:

If a category (e.g., "Production") has policies applied to entities like VMs, and the entity matches that category, the category-specific policy will override general policies.

This prioritization allows administrators to fine-tune alert policies for specific workloads or environments.

The correct answer isD. Software-only Encryption.

Nutanix supportsData-at-Rest Encryption (DARE)through bothhardware-basedandsoftware-basedmethods. Among the supported solutions,software-only encryptionis a widely used and officially supported method, especially whenSelf-Encrypting Drives (SEDs)are not in use.

Key facts about Nutanix DARE:

Enables encryption of data written to physical media.

Works at theCVM and controller layer, ensuring all I/O is encrypted before being persisted.

Software-based encryptioncan be enabled via Prism Central or command-line usingNative Key Management (NKM)orexternal KMIP-compliant key managers.

Hardware encryption (SED)is optional and not required for DARE.

Clarifications:

A. Storage Pool-only Encryption: Not valid; encryption applies at thecluster level, not only to storage pools.

B. Data-only Encryption: Ambiguous and not a Nutanix-supported term.

C. Cluster-only Encryption: Misleading; encryption is applied to data at rest, not to the "cluster" object.

Prism UI Navigation Path:

Settings > Security > Encryption

Official Reference:

Nutanix Security Guide – Data-at-Rest Encryption

Nutanix Bible – Encryption Section

Excerpt: “Nutanix supports software-only data-at-rest encryption using Native Key Management or external KMIP key managers, without requiring self-encrypting drives.”

Answer: D

For a Veeam Backup appliance using iSCSI to connect to an AHV-based Nutanix cluster, aData Services IP (DSIP)must be configured. The DSIP is a virtual IP that allows external systems to communicate with Nutanix storage using protocols such as iSCSI. This ensures seamless connectivity between Veeam and the Nutanix cluster.

A. Network Segmentation:While network segmentation is important for security, it is not specifically required for iSCSI connectivity.

B. Nutanix Objects:Nutanix Objects is used for object storage, not iSCSI connectivity.

C. Prism Central:Prism Central is used for multi-cluster management but is not involved in configuring iSCSI.

D. Data Services IP:Correct, as it enables external systems to connect via iSCSI.
