NEW QUESTION # 81
An administrator has identified and resolved a critical alert on the health dashboard.
What should the administrator do to confirm the alert/issue has been resolved?
Answer: A
Explanation:
The administrator should rerun the relevant Nutanix Cluster Check after completing the corrective action.
NCC evaluates cluster configuration, services, hardware and operational conditions against Nutanix-defined health criteria. A new PASS or appropriate INFO result provides technical confirmation that the underlying condition no longer exists.
Refreshing the Prism Element dashboard only reloads the displayed information. It does not independently retest the component or service that generated the alert. Deleting an email notification has no effect on the alert or cluster state. Manually marking an alert as resolved changes its administrative status but does not prove that the underlying fault has been corrected. Doing so without validation could conceal an active problem.
If the rerun produces WARN, FAIL or ERR rather than PASS or INFO, the administrator must review the new output and continue remediation. For a narrowly scoped issue, the relevant NCC check can be selected; a broader health review may justify running the complete NCC suite.

NEW QUESTION # 82
What resource should be used to ensure a successful upgrade of the hypervisors and AOS within a vSphere- based Nutanix cluster?
Answer: A
Explanation:
The Nutanix Compatibility and Interoperability Matrix must be consulted before upgrading AOS or the ESXi hypervisor in a vSphere-based Nutanix cluster. The matrix identifies supported combinations of AOS releases, ESXi versions, Prism components, hardware platforms and related software. This prevents the administrator from introducing a hypervisor release that the installed AOS version does not support.
Upgrade planning must consider the current and target versions together. If the target AOS version requires a different supported hypervisor level, the administrator must follow the prescribed upgrade order. Nutanix Lifecycle Manager and one-click upgrade workflows perform compatibility checks, but the matrix remains the authoritative planning resource for confirming the intended version combination.
Nutanix Validated Designs provide architectural and deployment guidance rather than an exhaustive version- compatibility decision. Hardware replacement documentation governs component service procedures. Partner Software Validation may establish support for particular third-party products, but it does not replace Nutanix' s platform compatibility matrix for AOS and ESXi.

NEW QUESTION # 83
When migrating ESXi VMs to an AHV-based cluster using Nutanix Move, what should be in place to ensure a successful migration?
Answer: B
Explanation:
Nutanix Move requires VMware Tools to be installed and current on guest VMs for supported ESXi-to-AHV migration workflows. VMware Tools provides guest-level information and operations needed during migration preparation and cutover. Its services support tasks such as obtaining guest details, coordinating shutdown or restart actions, and completing supported guest-side preparation.
Placing ESXi hosts in maintenance mode would normally evacuate or stop workloads and is not a standard migration prerequisite. Move is designed to migrate selected running workloads while the source infrastructure remains operational until cutover. Option C is incorrect because official Move requirements specify virtual hardware version 7 or later for the relevant support condition, not version 9 or later. Option D is also too restrictive: supported Move releases accommodate documented ESXi versions beyond only the 7.x family, subject to the current compatibility matrix.
Administrators must also verify network reachability, credentials, guest-operating-system support, source and target compatibility, and adequate target resources. However, among the choices, the explicit guest requirement is current VMware Tools. Reference: Nutanix Move 6.2 - Requirements . NHCF alignment:

NEW QUESTION # 84
What represents the smallest unit of virtualized data?
Answer: B
Explanation:
Among the listed components, a vDisk is the smallest storage object directly presented through the virtualization layer for use by a VM. A vDisk is created inside a storage container and appears to the guest as an attached disk device. A VM may contain several vDisks for its operating system, application binaries, databases, logs, or other data.
A storage pool is a higher-level aggregation of physical storage resources contributed by cluster nodes. A storage container is a logical subdivision of a storage pool that holds vDisks and applies relevant storage settings. Multiple containers can use the same underlying pool resources. The Extent Store is an AOS storage- layer repository or component used to persist data extents on each node; it is not a user-facing unit of virtualized data.
Although AOS internally divides vDisk data into extents and extent groups, neither "extent" nor "extent group" appears as an answer choice. "Extent Store" refers to the service or repository managing those structures, not the virtualized data object exposed to a workload. Consequently, vDisk is the correct answer within the documented storage hierarchy. Reference: Prism Central - Storage Components . NHCF alignment: storage pools, containers, and virtual disks.
NEW QUESTION # 85
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.
