NEW QUESTION # 59
An administrator needs to increase the available storage of an existing AHV virtual machine by adding a new vDisk.
Which method is supported to perform this task?
Answer: C
Explanation:
An administrator can add storage directly to an existing AHV VM by editing its configuration and selecting Add New Disk. In the disk configuration, the administrator specifies the device type, disk size, storage container, and supported controller or bus settings. The new vDisk is then attached to the VM and presented to the guest operating system, where it can be initialized, partitioned, and formatted.
Creating another VM is unnecessary because AHV supports modifying the virtual hardware of an existing VM. Increasing a host's local disk does not directly create guest storage; physical disks contribute capacity to the Nutanix distributed storage fabric rather than being individually assigned to a VM. Similarly, changing the size of a storage pool is an infrastructure-capacity operation and does not attach a new virtual disk to the selected workload.
A storage container holds the vDisk and provides access to the cluster's distributed storage resources.
Selecting the appropriate container during disk creation is therefore part of the supported workflow.

NEW QUESTION # 60
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.

NEW QUESTION # 61
What happens to pinned and Replication Factor 1-enabled VMs on a cluster node that is entering maintenance mode?
Answer: D
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 # 62
In a Nutanix cluster where compute nodes run ESXi, which hypervisor is required on storage-only nodes added to the cluster?
Answer: A
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. Reference: Prism 7.5 - Storage-Only Nodes . NHCF alignment: compute-only and storage- only node configurations.
NEW QUESTION # 63
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.
