NEW QUESTION # 15
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:

NEW QUESTION # 16
What node type can be part of a Nutanix HCI cluster but will not run user virtual machines?
Answer: C
Explanation:
A Nutanix storage-only node contributes storage capacity and storage-processing resources to a cluster but is deliberately prevented from hosting guest or user virtual machines. Nutanix documents storage-only nodes as unschedulable for guest workloads. This separation allows an organization to expand storage independently when additional compute capacity is unnecessary.
A storage-only node remains part of the distributed AOS storage architecture and participates in relevant cluster services. Its defining restriction is that the hypervisor scheduler does not place user VMs on it. Storage- only configurations are supported with specified hypervisors and hardware platforms, subject to the applicable compatibility and configuration requirements.
A compute-only node has the opposite purpose: it adds compute resources and can run application VMs but does not provide the conventional local AOS storage contribution or Controller VM found on an HCI node. A standard HCI node contributes both compute and storage and can host user workloads. "Worker" is principally a Kubernetes node role rather than the Nutanix HCI node type described by this question.

NEW QUESTION # 17
Which security option should be implemented to ensure that all intra-cluster communication is secured?
Answer: C
Explanation:
Network Encryption is the security control directed at protecting data while it traverses the network between Nutanix cluster components. It provides cryptographic confidentiality and integrity for supported intra-cluster traffic, preventing captured traffic from being interpreted or modified without detection. In AOS 7.5, the documented intra-cluster data-in-transit encryption capability specifically covers Stargate storage traffic.
Accordingly, the examination wording should be interpreted as asking which option cryptographically secures intra-cluster communications, for which Network Encryption is the only valid choice.
Network Segmentation serves a different purpose. It isolates traffic categories-such as management, backplane, or replication traffic-onto separate networks. Segmentation can reduce exposure and limit broadcast or failure domains, but isolated traffic is not necessarily encrypted. Cluster Lockdown restricts administrative access, particularly access paths involving hosts and Controller VMs; it does not encrypt packets moving between cluster services. "vSwitch Lockdown" is not the relevant Nutanix data-in-transit security mechanism.
The decisive distinction is therefore encryption versus isolation or access restriction. If the requirement is that intercepted traffic must remain unreadable, an encryption capability is required. Segmentation may complement that control, but cannot replace it.

NEW QUESTION # 18
An administrator needs to decrease the number of CPUs assigned to a VM.
What is the first step?
Answer: D
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 # 19
A virtual machine needs to be placed on a different storage location within the cluster.
Which task should be performed?
Answer: D
Explanation:
Moving a VM's existing storage to a different storage container requires a vDisk placement change, implemented through live vDisk migration across storage containers. Nutanix supports migrating the attached vDisks of a running VM to a target container without deleting or shutting down the VM, subject to the documented requirements and limitations. The administrator can move an individual vDisk or all supported vDisks belonging to the VM.
A category assigns metadata used for organization, governance, automation, and policy association; it does not directly relocate existing disk data. Image placement policies determine which clusters receive images from the image service, not where an existing VM's attached vDisks are stored. A storage policy controls storage characteristics such as QoS or other supported data-service properties. It is not the general storage- container migration task.
The keyed answer D is particularly problematic because Nutanix documents that a vDisk cannot be migrated to another container while a storage policy is configured for the associated VM. Applying such a policy can therefore prevent the requested migration rather than accomplish it. References: Migrating a vDisk to Another Container and Storage Policy Management . NHCF alignment: storage operations and vDisk management.
