When configuring dual encryption, which key management method is supported?
- A. Lockdown Mode Enabled
- B. Trusted Platform Module
- C. External Key Manager
- D. Native Key Manager
Answer: C
Explanation:
When configuring dual encryption in Nutanix, anExternal Key Manager(EKM) is required. This allows the cluster to use an external hardware-based or software-based key management system to securely store and manage encryption keys. The combination of external and native encryption ensures compliance with high security standards.
* A. Trusted Platform Module:Incorrect, as TPM is not used for managing dual encryption keys.
* B. External Key Manager:Correct, as dual encryption relies on an external system to manage keys.
* C. Native Key Manager:Incorrect, as native key management alone does not support dual encryption.
* D. Lockdown Mode Enabled:Incorrect, as Lockdown Mode relates to cluster security, not encryption key management.

An administrator wants to change from Redundancy Factor 2 to 3, but it is not allowed.
What must the administrator check?
- A. Check that the cluster has been properly licensed.
- B. Check that the cluster has five or more nodes.
- C. Check hardware availability of the nodes.
- D. Check AOS version and upgrade, if needed.
Answer: B
Explanation:
Redundancy Factor 3 (RF3) requires a minimum of five nodes in the cluster to ensure that data can be distributed across enough nodes to tolerate the failure of two nodes. If the cluster has fewer than five nodes, RF3 cannot be enabled.
* A. Check that the cluster has been properly licensed:Licensing is not directly related to enabling RF3.
* B. Check that the cluster has five or more nodes:Correct, as RF3 requires at least five nodes.
* C. Check hardware availability of the nodes:While hardware health is important, it does not determine RF3 eligibility.
* D. Check AOS version and upgrade, if needed:RF3 requirements are not specific to an AOS version.

NEW QUESTION # 25
What role does a Replication Factor of 2 or 3 play in ensuring data integrity and recovery?
- A. It accelerates data transfer to remote backup sites.
- B. It limits the scope of hardware failures during recovery operations.
- C. It reduces the need for offsite backup solutions.
- D. It ensures that multiple copies of data are available for recovery.
Answer: D
NEW QUESTION # 26
An administrator receives the alert:
What is the most likely cause?
- A. Other nodes in the cluster may not have enough resource available.
- B. This node in the cluster is already in maintenance mode.
- C. This node in the cluster may not have enough resources available.
- D. Another node in this cluster is already in maintenance mode.
Answer: A
Explanation:
When a Nutanix cluster alert occurs, indicating maintenance mode issues, the most likely cause is that another node in the cluster is already in maintenance mode. Nutanix clusters enforce restrictions to prevent more than one node from entering maintenance mode simultaneously. This ensures the cluster can maintain resiliency and availability, adhering to the redundancy factor (RF) policy.
If another node is already in maintenance mode, the cluster cannot afford to have additional nodes enter maintenance without compromising data and service availability.

NEW QUESTION # 27
An administrator is conducting updates in a Nutanix cluster and is being prompted for handling non- migratable VMs.
Which VM type is non-migratable?
- A. Memory Overcommitted
- B. VMs marked as an Agent
- C. VMs O VMs with attached Volume Groups
- D. VMs without NGT
Answer: C
Explanation:
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.

NEW QUESTION # 28
An administrator is building a new Windows VM on a Nutanix AHV cluster. However, when the administrator tries to install the OS, no disks are listed as available.
What does the administrator need to do to resolve the issue?
- A. Mount and install the Nutanix Guest Tools.
- B. Mount and install the VirtIO drivers.
- C. Add a second disk to the VM.
- D. Enable Turbo Mode on the VM.
Answer: B
Explanation:
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.

What type of NTP/time sources are recommended for Nutanix clusters?
- A. Internal NTP sources
- B. External ISP NTP sources
- C. Rate-limited NTP sources
- D. Windows time sources
Answer: A
Explanation:
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.

NEW QUESTION # 33
When is deduplication recommended?
- A. Server workloads
- B. Full clone VMs
- C. Linked Clone VMs
- D. Cold data
Answer: B
Explanation:
Deduplication is most effective withfull clone VMsbecause it reduces redundant data blocks stored on the cluster. Full clone VMs often contain identical OS and application files, making them ideal candidates for deduplication, which optimizes storage usage and improves efficiency.
Other options:
* Server workloads: May benefit from deduplication but not as significantly as full clone VMs.
* Linked Clone VMs: Already share base disk images, so deduplication offers limited benefits.
* Cold data: Deduplication is less effective for data that isn't accessed frequently.

Which bridge does the Controller VM use by default to communicate with the AHV host it runs on?
- A. bro
- B. vs0
- C. virbro
- D. bridge0
Answer: D
Explanation:
The Controller VM (CVM) uses thevs0bridge by default to communicate with the AHV host it runs on. The vs0bridge 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.
