NEW QUESTION # 68
An administrator needs to take an immediate snapshot of a single VM.
How should the administrator complete this task?
Answer: D
Explanation:
A manual, immediate snapshot of an individual VM is created from the VM dashboard in Prism Element. The administrator opens the VM table, selects the target VM and invokes the Take Snapshot action. Prism then creates a point-in-time snapshot containing the VM configuration and the supported virtual-disk state.
This procedure is appropriate when the requirement concerns one VM and the snapshot must be taken immediately. Prism Central Data Protection is used for broader protection policies, recovery points, protection schedules and multi-cluster disaster-recovery operations. Those capabilities are valuable for recurring or policy-based protection but are not the direct manual workflow described in the question.
Connecting to a Controller VM is unnecessary and would bypass the supported administrative interface. The Prism Central Images service manages deployable disk images, ISO files and VM image resources; an image is not a point-in-time snapshot of a running VM.
For application-consistent protection, additional guest-side preparation such as Nutanix Guest Tools may be required. A standard manual snapshot, however, is initiated through the selected VM's Prism Element actions.

NEW QUESTION # 69
Which component is required to prevent split-brain scenarios on a two-node ROBO cluster?
Answer: D
Explanation:
A two-node cluster lacks the natural majority available in a conventional cluster containing three or more voting members. If communication between its two nodes is interrupted, each node could otherwise interpret the other node as failed and attempt to continue independently. That condition creates a split-brain risk because both sides could consider themselves authoritative.
The external Witness VM supplies the independent arbitration required for the two-node configuration. It is deployed in a separate failure domain and maintains communication with the cluster. During a node or communication failure, witness participation allows the cluster to distinguish the surviving authoritative side and avoid both nodes independently continuing cluster operations. Separating the witness from the two data- bearing nodes is critical because placing all voting components in the same failure domain would undermine the tie-breaking design.
Prism Element is the local cluster-management interface, while Prism Central provides centralized management across clusters. Neither substitutes for an independent quorum witness. Foundation Central supports centralized discovery and deployment activities and does not arbitrate two-node cluster ownership.
Nutanix documentation identifies the external Witness VM as part of the supported two-node ROBO configuration. References: Prism 7.5 - Two-Node Clusters and Witness for Two-Node Clusters . NHCF alignment: valid cluster configurations, availability, and failure handling.
NEW QUESTION # 70
After deploying a VM, which tool provides additional capabilities, such as file-level restore?
Answer: D
Explanation:
Nutanix Guest Tools is a collection of guest-resident services and utilities that extends the integration between a deployed virtual machine and the Nutanix platform. One of its principal capabilities is Self-Service Restore, also described as file-level restore. When the feature is enabled and NGT is installed, an authorized VM administrator can access files from a Nutanix-protected snapshot without requiring the infrastructure administrator to restore the entire VM.
NGT establishes the guest-side functionality required to expose and use supported recovery services.
Depending on the operating system and enabled components, NGT also supports functions such as application-consistent snapshot coordination and guest communication with the Nutanix platform.
The other tools serve different lifecycle stages. Nutanix X-Ray validates platform performance, resilience and infrastructure behavior. Foundation images physical nodes and creates or expands Nutanix clusters. Nutanix Move migrates workloads from supported source environments to Nutanix AHV or other supported targets.
None of these tools supplies guest-level file recovery after normal VM deployment.

NEW QUESTION # 71
What would cause storage compression to become automatically disabled?
Answer: A
Explanation:
Nutanix AOS automatically disables compression when metadata usage becomes high. The Prism 7.5 storage documentation explicitly identifies this condition and states that an alert is generated when automatic disablement occurs. Consequently, option D is the verified answer, replacing the supplied answer A.
Compression requires AOS metadata resources to track compressed extents and the associated data layout. If metadata consumption reaches a protective threshold, continuing compression could place additional pressure on the metadata services required for normal storage operation. AOS therefore prioritizes platform stability and metadata availability by disabling compression and notifying the administrator. The corresponding health alert should be investigated to determine why metadata usage has increased and whether workload characteristics or another storage condition requires remediation.
High write activity may increase storage workload and influence when post-process compression can execute, but it is not the documented automatic-disable trigger in this question. High reads similarly do not directly cause compression to be disabled. High physical-capacity consumption generates its own capacity warnings and corrective requirements but is distinct from the metadata threshold governing compression.

NEW QUESTION # 72
An administrator is working with Nutanix Support and has been asked to submit the NCC logs for further review.
How should the administrator gather the logs for the support case?
Answer: D
Explanation:
The supported Prism Element workflow for gathering diagnostic data is the Collect Logs feature. From the Health dashboard, the administrator opens the Actions menu, selects Collect Logs, identifies the relevant nodes and components, specifies the required time range or collection parameters, and starts the log-collection task. The resulting archive can then be associated with or uploaded for the Nutanix Support case.
Pulse is a proactive support and telemetry capability that periodically provides diagnostic system information to Nutanix. It does not automatically transmit every detailed NCC or component log required for a specific investigation. Nutanix documentation notes that when Pulse data is insufficient for diagnosis, Support may request a separate diagnostic log collection.
"Export Logs" and "Download Logs in Prism Central" are not the documented names of the NCC collection workflow described in the question. The explicit Health dashboard operation is Collect Logs. This process also allows the administrator to control which nodes and components are included, preventing irrelevant data from unnecessarily enlarging the support bundle. Reference: Prism 7.5 - Collecting Logs Using Prism Element . NHCF alignment: collecting support data, using health functions, and collaborating with Nutanix Support.
