The correct answer isB. UTC.

When creating Linux VMs in a Nutanix environment (or in any enterprise-grade production environment), it isbest practice to use UTC(Coordinated Universal Time) as the system timezone. This ensures:

Consistencyacross distributed systems

Accurate log correlation

Avoidance of issues with daylight saving time (DST)

Simplifiedcentralized monitoring and troubleshooting

Clarifications:

A (Eastern)andD (Central)are region-specific and may introduce time skew across systems.

C (Local)is ambiguous and depends on the underlying hardware or hypervisor setting, which can lead to inconsistent behavior.

Official Reference:

Linux Admin Best Practices

Nutanix Best Practices Guide – VM Provisioning Section

Excerpt: “For consistency across environments, it is recommended to configure all Linux virtual machines to use UTC timezone, particularly in clustered and distributed applications.”

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.

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

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.

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.

The correct answer isB. Use the Recycle Bin.

TheRecycle Binfeature in Nutanix enablessoft deletion of VMs, where the deleted VM is retained in a non-visible state for24 hoursby default before being purged. During this retention window:

NutanixSupportcan assist in recovering the VM in itsmost up-to-date state.

No snapshots or backups are required for this recovery mechanism.

TheRecycle Bin is enabled by defaultin recent AOS versions.

UI Path (for visibility):

This functionality is internal and requires Support engagement for recovery.

Clarification:

A (Nutanix Recovery Plan):Used with NearSync or Async DR; does not recover recently deleted VMs automatically.

C (NC2 on AWS):Disaster recovery infrastructure, not applicable to local deleted VM recovery.

D (Third-party tools):Irrelevant to Nutanix native functionality.

Official Reference:

Nutanix Administration Guide – VM Recovery using Recycle Bin

Excerpt: “Deleted VMs can be recovered by Nutanix Support within 24 hours using the Recycle Bin soft-delete capability.”

Answer: B

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.

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

TheTasksdashboard in Prism Element provides detailed visibility into the progress of all ongoing and completed tasks, including Life Cycle Manager (LCM) updates. Administrators can monitor the step-by-step status of LCM operations, track failures, and identify bottlenecks.

A. Analysis:Incorrect, as this is used for performance monitoring, not task progress.

B. Tasks:Correct, as it displays detailed progress for updates and other operations.

C. Hardware:Incorrect, as this focuses on the state and configuration of hardware components.

D. Alerts:Incorrect, as this shows system alerts and issues, not detailed task progress.

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.

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