NEW QUESTION # 24
In a Nutanix cluster where compute nodes run ESXi, which hypervisor is required on storage-only nodes added to the cluster?
Answer: D
Explanation:
A Nutanix storage-only node operates with AHV even when the hyperconverged compute nodes in the same cluster use VMware ESXi. The storage-only node contributes storage capacity and runs the Controller VM and required Nutanix services, but it does not host ordinary user VMs. Using AHV on the storage-only node preserves compatibility with the Nutanix storage-only architecture and avoids requiring an additional third- party hypervisor licence solely for a node that supplies storage.
This creates a supported mixed-hypervisor cluster configuration: ESXi remains on the compute-capable HCI nodes, while AHV runs on the storage-only nodes. Administrators must observe the documented restrictions for cluster expansion, network segmentation, maintenance, and workload placement in this configuration.
User workloads remain on the ESXi compute nodes because the AHV storage-only nodes are not available as general VM execution targets.
Hyper-V is not used for this ESXi storage-only-node design. Although AHV is based on KVM technology, the supported Nutanix hypervisor product and configuration is specifically AHV, making generic KVM an incorrect selection.

NEW QUESTION # 25
What happens to pinned and Replication Factor 1-enabled VMs on a cluster node that is entering maintenance mode?
Answer: B
Explanation:
Pinned VMs and Replication Factor 1-enabled VMs with node affinity cannot be safely live migrated during host maintenance. Prism therefore identifies these VMs as non-migratable and requires them to be powered off before the node can complete entry into maintenance mode.
A pinned VM has a placement constraint binding it to a particular host. Moving it automatically would violate that constraint. An RF1-enabled VM has only one copy of its applicable vDisk data. When that data is associated with the node entering maintenance, another host cannot provide the same resilient storage access expected for an ordinary RF2 or RF3 VM. Powering off prevents the workload from continuing in an unsupported or inaccessible state.
Normal live-migratable VMs are moved to other nodes, subject to available CPU and memory capacity. HA- protected workloads can also be relocated according to the maintenance workflow. Pinned and RF1-affined VMs are handled separately, and Prism prompts the administrator to confirm their shutdown.
Before proceeding, the administrator should identify business impact, obtain an approved outage window, confirm cluster resiliency, and verify that affected applications can be restarted after the node exits maintenance mode.

NEW QUESTION # 26
How many Controller VMs (CVMs) will a five-node HCI cluster have?
Answer: D
Explanation:
A conventional five-node Nutanix HCI cluster has five Controller VMs-one CVM running on each node.
AOS operates as a distributed storage and data-services system rather than relying on a single centralized storage controller. The per-node CVM architecture provides local access to the node's storage devices while cooperating with the CVMs on the other nodes to form the distributed AOS storage fabric.
The CVMs collectively provide services associated with data placement, replication, metadata, caching, compression, deduplication, snapshots, and cluster storage management. If a CVM becomes unavailable, the host can access storage services through another CVM, subject to cluster health and connectivity. The remaining CVMs also maintain the distributed cluster services required for continued operation.
The number of CVMs therefore normally matches the number of HCI nodes: three nodes produce three CVMs, four nodes produce four, and five nodes produce five. The count does not represent the replication factor or the number of simultaneously tolerated failures.
Compute-only nodes are a specific exception because they do not run a CVM. However, the question explicitly describes a five-node HCI cluster, so each node contributes storage and runs a Controller VM.

NEW QUESTION # 27
A volume group is a collection of which components?
Answer: C
Explanation:
A Nutanix volume group is a collection of logically related virtual disks, also described as vDisks or volumes.
The group provides block-storage resources that can be attached directly to guest VMs or presented through iSCSI to supported consumers. Grouping the disks allows them to be administered, attached, protected, cloned, and managed as a related storage entity.
A storage pool aggregates physical storage capacity contributed by cluster nodes. Storage containers are logical subdivisions created within a storage pool and hold virtual disks. Consequently, a volume group can use vDisks created on Nutanix storage, but it is not a collection of pools or containers. Controller VMs run the distributed storage and cluster services on individual nodes and are unrelated to volume-group membership.
Each volume group has its own name and UUID, and administrators can add or remove virtual disks according to platform limitations. A group may be associated with one or more consumers depending on the attachment mode and supported use case. This structure is particularly suitable for applications requiring shared block devices, direct iSCSI access, or multiple related application volumes.

NEW QUESTION # 28
In an AHV Metro environment, which feature must be installed on a Windows VM to ensure successful cross- cluster migration?
Answer: A
Explanation:
Nutanix Guest Tools must be installed and configured on the protected Windows VM when required by the AHV Metro and recovery-plan workflow. Nutanix DR documentation specifies supported NGT versions as a guest-level prerequisite for protected entities participating in relevant cross-cluster operations.
NGT supplies guest integration that allows the Nutanix platform to coordinate VM-specific operations during protection and recovery workflows. It can support application-consistent processing, guest communication and the handling of attached resources where applicable. For Windows workloads, installing NGT ensures that the guest participates correctly in the supported Nutanix DR workflow rather than being treated solely as an unmanaged virtual-machine object.
VirtIO supplies the storage and network drivers required for Windows to operate efficiently on AHV, but it is not the Metro-specific guest integration requested by the question. VMware Tools applies to VMware guest integration and is not the corresponding AHV component. The Witness service is an external availability component used to arbitrate failures between Metro sites; it is not installed inside each Windows VM.
