The correct answer isB. Disabled.

When creating a new storage container in Prism Element or Prism Central,compression is disabled by default. The administrator mustexplicitly enableone of the available compression options:

Inline Compression

Post-process Compression

If no compression type is selected, the container remains uncompressed.

UI Navigation Path:

Storage > Storage Containers > Create Container > Compression Settings

Clarifications:

A (60 mins)andC (15 mins): Not standard default post-process intervals.

D (Inline): Must be manually selected.

Official Reference:

Nutanix Storage Administration Guide – Creating and Configuring Containers

Excerpt: “Compression is disabled by default during container creation. Admins must select inline or post-process if desired.”

Answer: B

In Nutanix Prism Element, thered heart iconat the top-right of the UI indicates that there is acritical alertaffecting the cluster's health. This icon is part of theAlert Monitoring System, and clicking on it redirects the user to theAlerts dashboard, where all current active alerts—including their severity, source, and recommended remediation steps—are listed.

What to do:

Navigate to theAlertssection.

Review allcritical alertsfor further diagnosis.

Cross-reference with theHealth dashboardif deeper system component checks are needed.

Clarification of Other Options:

A. Health:Summarizes system component states but does not provide detailed alert causes.

B. Tasks:Tracks user-initiated jobs, unrelated to fault diagnosis.

D. Analysis:Used for performance metrics and trends, not fault alerts.

Prism UI Navigation Path:

Click the red heart icon → Alerts Dashboard

Official Reference:

Nutanix Administration Guide – Alerts and Monitoring

Excerpt: “A red heart icon in Prism indicates a critical alert. Use the Alerts dashboard to identify and resolve the issue.”

The correct answer isB. Internal NTP sources.

Nutanix strongly recommends configuringreliable internal NTP sources(e.g., enterprise-managed NTP servers or domain NTP servers) to ensure:

Time consistency across all nodes and CVMs

Accurate logging, monitoring, authentication (e.g., Kerberos), and cluster operations

Avoiding dependency onexternal/public NTPsources, which may berate-limited, unavailable, or blockedby firewalls

Clarifications:

A (Windows time sources):Generally discouraged unless they are configured to use a stratum 1/2 reliable upstream source.

C (Rate-limited sources):Not recommended; can result in dropped or inconsistent time updates.

D (External ISP NTP):Not preferred for production clusters due to reliability concerns.

Prism UI Navigation Path:

Settings > NTP Servers

Official Reference:

Nutanix Best Practices Guide – NTP Configuration

Excerpt: “Use reliable and consistent internal NTP servers for all Nutanix clusters to maintain time synchronization.”

Answer: B

To run a full health check in Prism Element, the administrator should first select theActionsmenu. From there, the administrator can choose to execute health checks for the entire cluster or specific components. This ensures a comprehensive evaluation of the cluster’s health.

Other options:

Scheduled: Refers to predefined or automated health checks.

Checks: Displays the list of checks but doesn’t initiate them.

Failed: Filters checks based on their status but doesn’t start a new check.

The correct answer isC. Perform an inventory.

To ensure theLCM Frameworkand its associated component metadata are updated, the administrator must perform afresh LCM inventory. This process:

Retrieves the latest metadata and framework version from the Nutanix support portal (if the cluster is connected).

Detects current component versions and identifies available updates.

Clarifications:

A (Upgrade AOS):LCM is independent of AOS version updates.

B (Restart genesis):Unnecessary and not relevant to LCM framework versioning.

D (NCC):Useful for cluster health, but does not affect LCM updates.

Prism Central UI Navigation Path:

Operations > LCM > Perform Inventory

Official Reference:

Nutanix LCM Guide – Updating the LCM Framework

Excerpt: “To receive the latest framework version and component metadata, perform an LCM inventory on a connected cluster.”

The Controller VM (CVM) uses thevs0bridge by default to communicate with the AHV host it runs on. Thevs0bridge is a virtual switch configured on the AHV host, providing connectivity between the CVM, virtual machines, and external networks. This setup ensures efficient network communication within the Nutanix cluster.

Other options:

virbro: Typically used in standalone KVM configurations, not in Nutanix AHV.

broandbridge0: Incorrect references to Nutanix networking structures.

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.

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.”

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.

The correct answer isB. Group of physical disks.

In Nutanix architecture:

AStorage Poolis theaggregation of physical storage devices(SSD, HDD) across all nodes in a cluster.

Each storage pool backs one or moreStorage Containers, which are logical partitions used for data placement.

Storage poolscannot span clustersand are always confined to the cluster in which they are defined.

Clarifications:

A (Storage Containers): These are logical groupingswithinstorage pools.

C (Boot Drives): These are not part of the pool.

D (vDisks): These exist within VMs and are backed by containers, not pools directly.

Prism UI Navigation Path:

Storage > Storage Pools

Official Reference:

Nutanix Bible – Storage Pool Definition

Nutanix Storage Admin Guide

Excerpt: “A storage pool is made up of physical disks from one or more nodes and serves as the physical storage foundation for containers.”

Answer: B

The correct answer isA. NearSync Replication.

Key Concepts from Official Nutanix Documentation:

Nutanix supports various types of data replication methods depending on the Recovery Point Objective (RPO), Recovery Time Objective (RTO), and the latency between the sites.

Metro Availabilityrequires a maximum latency of<5ms RTTand is used forzero RPO synchronous replication. Since the given latency is 10ms,Metro Availability is not supportedin this case.

To remove old VM snapshots, the task should be completed from theVM dashboardin Prism Element. This dashboard allows administrators to manage virtual machine-related operations, including snapshot creation, deletion, and restoration. Steps include:

Navigate toPrism Element > VM.

Select the VM for which snapshots need to be deleted.

Click onSnapshots, then delete the selected snapshots.

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.

Fordark site clusters, theNutanix Compatibility Bundlemust be downloaded prior to running LCM Inventory or updates. This bundle contains the necessary metadata and software binaries to perform inventory collection and upgrades in environments without internet connectivity.

A. Nutanix Foundation:Incorrect, as Foundation is used for initial deployments, not for LCM updates.

B. Nutanix Compatibility Bundle:Correct, as it contains the necessary files for offline LCM operations.

C. Nutanix Prism Central:Incorrect, as this does not pertain to offline updates.

D. Nutanix Foundation Platform:Incorrect, as this is not required for LCM Inventory or updates.

To verify if the cluster is currently protected from potential data loss due to a component failure, the administrator should check theData Resiliency Status widgeton the Prism Element Home dashboard. This widget provides real-time information about the cluster's resiliency status, including warnings or errors about data redundancy or protection.

Other options:

A. Select the gear icon and then select Pulse:Pulse is used for telemetry data, not data resiliency status.

B. Click on Home and then Alerts:Alerts show specific issues but do not directly indicate the overall resiliency status.

D. Navigate to the Health dashboard:The Health dashboard provides detailed health checks but does not display the current resiliency status.

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 isD. Flow Virtual Networking (FVN).

Flow Virtual Networking (FVN)is a Nutanix solution that enablesadvanced network virtualization, including:

VPCs (Virtual Private Clouds)

Overlapping IP address spaces

Self-service network provisioning

Multi-tenancy support

Microsegmentation

FVN abstracts physical networking and allows tenants to manageisolated logical networks, providing cloud-like networking capabilities directly integrated with AHV.

Clarifications:

A. Nutanix Kubernetes Platform (NKP):Orchestrates containers; does not provide virtualized network infrastructure.

B. Flow Network Security:Focuses onmicrosegmentationandpolicy enforcement, not on VPC or L3 abstraction.

C. Nutanix Database Service (NDB):Manages DBaaS; not related to networking.

Official Reference:

Nutanix Flow Virtual Networking Tech Note

Nutanix Documentation Portal – Flow Virtual Networking

Excerpt: “Flow Virtual Networking provides VPCs, overlapping IPs, and self-service networking capabilities for secure multi-tenancy in Nutanix AHV clusters.”

Answer: D

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.

TheRecycle Binin Nutanix clusters temporarily stores deleted VMs for 24 hours, allowing administrators to recover them if needed. This feature helps protect against accidental deletions by providing a grace period for recovery before permanent deletion occurs.

A. Stores the OpLog's most recent deleted data in case of a CVM failure:Incorrect, as the OpLog pertains to write operations, not VM deletion.

B. Keeps deleted VMs for 24 hours for recovery:Correct, as the Recycle Bin's purpose is temporary VM recovery.

C. Allows administrators to undo the last five actions:Incorrect, as there is no such feature for undoing multiple actions in Prism.

D. Centralizes the deleted data from the different VMs in the cluster:Incorrect, as the Recycle Bin is specifically for deleted VMs, not generalized data centralization.
