NEW QUESTION # 13
An administrator needs to decrease the number of CPUs assigned to a VM.
What is the first step?
Answer: A
Explanation:
The VM must be powered off before the administrator can reduce its CPU allocation. CPU hot-plug capabilities permit supported guest operating systems to receive additional virtual CPU resources while running, but they do not provide a supported mechanism for removing active processors from a powered-on VM. Nutanix documentation states that the number of CPUs cannot be decreased while the VM is powered on.
After shutting down the guest cleanly and confirming that the VM is off, the administrator can edit the VM configuration, reduce the required vCPU count or associated CPU topology, save the change, and restart the VM. The proposed configuration must remain valid-for example, the relationship between sockets, vCPUs, and cores must be supported.
Enabling Hot-Add addresses CPU expansion rather than reduction. Nutanix Guest Tools supplies guest integration and operational capabilities but does not override hypervisor restrictions on CPU removal. A snapshot may be useful as an optional change-control precaution, but it does not make CPU reduction possible and is not the required first step.
The technically necessary action is therefore to power off the VM. Reference: AHV - Virtual Machine Memory and CPU Hot-Plug Configurations . NHCF alignment: modifying VM compute resources and understanding hot-plug limitations.
NEW QUESTION # 14
Which technology helps maintain operational resilience related to hardware?
Answer: A
Explanation:
Cluster Fault Tolerance directly defines how many simultaneous disk or node failures a Nutanix cluster can withstand within its configured failure domain while maintaining data availability. It is therefore the technology most directly associated with resilience against physical hardware failures.
For example, 1N/1D fault tolerance allows the cluster to tolerate the failure of one node or one disk, subject to the required node count, replication factor, available capacity, and current data-resiliency state. Higher fault- tolerance configurations can withstand additional simultaneous failures but require more nodes, failure domains, data copies, and usable-capacity overhead.
Acropolis Dynamic Scheduler addresses VM placement and resource contention. It can move workloads to improve balance, but it does not establish the number of hardware failures the storage layer can tolerate.
Capacity reservations can preserve resources for workload restart or data rebuilding, but they support rather than define the cluster's fault-tolerance level. High Availability restarts or protects VMs following host failures; it is related to workload availability but is not the specific measure of storage resilience across disks, nodes, blocks, or racks.
The decisive wording is "resilience related to hardware," which maps directly to Cluster Fault Tolerance.

NEW QUESTION # 15
Which Nutanix support case priority level is used for a non-critical loss of use with medium to low impact?
Answer: D
Explanation:
Nutanix classifies this condition as Priority 3, or P3. The official support definition describes P3 as a normal- priority case involving a minor inconvenience or an occasional, non-critical issue that requires resolution but has not materially reduced productivity. Its defining language includes: "A non-critical loss of use with medium to low impact." A short-term workaround is generally available.
P1 is reserved for emergency conditions in which production systems are unavailable or unusable, critical functionality is down, significant data loss is occurring or threatened, and no procedural workaround exists.
P2 applies when production remains available but experiences major degradation or the loss of important functionality, materially affecting part of the organization's operations. P4 covers low-impact informational requests, including questions about documentation, procedures, configuration, or account setup.
The scenario uses the defining P3 wording rather than merely describing a general support question. It therefore cannot be reduced to P4, while its non-critical and limited-impact characteristics exclude P1 and P2.
The correct priority is C. Reference: Nutanix Support Policies and Priority Definitions . NHCF alignment:
support-case creation, priority selection, and effective escalation practices.
NEW QUESTION # 16
Which number of node(s) can be placed into maintenance mode at the same time in a cluster?
Answer: A
Explanation:
Nutanix permits only one node per cluster to be placed in maintenance mode at a time. This restriction protects cluster availability and ensures that sufficient compute, storage and metadata services remain operational while maintenance is performed. Before entering maintenance mode, Prism verifies whether the cluster has adequate resiliency and whether the workloads hosted by the node can be evacuated or otherwise handled safely.
For AHV, the maintenance workflow migrates eligible user VMs to other available hosts. The Controller VM on the affected node is then placed into an appropriate maintenance state so that storage services can continue through the remaining CVMs. Attempting to maintain multiple nodes simultaneously could exceed the cluster' s fault-tolerance capability, particularly if another unplanned node or disk failure occurs during the procedure.
The limitation is cluster-wide, not one node per hardware block. The absence of powered-on VMs also does not authorize every node to enter maintenance mode because AOS storage and cluster-control services still depend on quorum and service availability.
NHCF/NCA reference: Cluster maintenance, node maintenance, resiliency and hardware-maintenance procedures; NCA Section 3, "Identify hardware maintenance tasks." Official references: Prism 7.5-Node Maintenance Mode , AOS 7.5-ESXi Node Maintenance .
NEW QUESTION # 17
When migrating ESXi VMs to an AHV-based cluster using Nutanix Move, what should be in place to ensure a successful migration?
Answer: A
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:
