NEW QUESTION # 60
How many Controller VMs (CVMs) will a five-node HCI cluster have?
Answer: B
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 # 61
An administrator needs to ensure that business-critical VMs maintain normal CPU performance.
Which action can the administrator take to generate alerts when VMs are oversubscribed during peak hours?
Answer: A
Explanation:
CPU Ready Time measures the percentage of time that a VM's virtual CPUs are ready to execute but cannot be scheduled on physical CPU resources. It is therefore a direct indicator of processor contention or CPU oversubscription. A VM can show moderate CPU utilization while still suffering poor response times because its vCPUs are waiting for execution time.
Prism Central supports user-defined alert policies based on infrastructure metrics, including VM CPU Ready Time. The administrator can define a threshold and evaluation period so that an alert is generated when scheduling delays exceed an acceptable level during peak demand. This produces proactive notification instead of requiring periodic manual review.
Pulse sends diagnostic information to Nutanix Support but does not create the workload-specific threshold requested. Increasing vCPU allocation without first validating contention may worsen CPU Ready Time because the hypervisor must schedule additional virtual processors. Reviewing average CPU usage is retrospective and does not automatically generate an alert. The most precise control is therefore a custom CPU Ready alert. References: Prism Central 7.5 - Alert Metrics and Intelligent Operations - Chart Metrics .
NEW QUESTION # 62
Which statement best describes the requirement for migrating a vDisk between storage containers in Nutanix AOS?
Answer: D
Explanation:
AOS supports live vDisk migration between storage containers while the vDisk remains attached to a powered-on guest VM. The VM does not need to be shut down or deleted. This capability allows administrators to move individual vDisks or all eligible vDisks associated with a VM to a container providing different storage settings.
Storage-container properties can include replication factor, encryption, compression, deduplication, and erasure coding. Migrating a vDisk to another container is therefore a controlled method of changing the storage characteristics applied to that disk without interrupting the running workload.
The operation does not require cluster maintenance mode, and existing snapshots do not universally need to be deleted. However, important restrictions apply. Migration cannot proceed when an applicable Prism Central storage policy is configured for the associated VM. Protected VMs may also need to be removed from their protection domain or protection policy before migration. The target container must have sufficient free capacity, and operations such as cloning, resizing, or taking new snapshots may be blocked while migration is active.
The essential requirement tested is that the VM may remain powered on during the storage-container migration.

NEW QUESTION # 63
A virtual appliance provides network services required by other VMs on the same host. The VM should start before other VMs, shut down after other VMs, and remain associated with the same host during maintenance operations.
Which VM configuration best matches this requirement?
Answer: B
Explanation:
The virtual appliance should be configured as an agent VM. AHV agent VMs are intended for infrastructure or service appliances that provide host-local functionality required by ordinary guest VMs. The agent designation gives the VM specialized power-order and placement behavior: it is powered on before normal VMs, powered off after normal VMs, and is not live-migrated to another host while running.
If the host experiences an HA event or enters maintenance mode, the agent VM is powered off rather than migrated. After the host returns to normal operation, the agent VM is powered on again on that same host.
This preserves the intended host-local association of services such as network, security, monitoring, or storage appliances.
VM-Host affinity alone expresses a placement preference or requirement but does not provide the complete agent-VM startup and shutdown ordering. Nutanix Guest Tools provides guest-management and snapshot capabilities, not host-local service-appliance semantics. Disconnecting the vNIC would prevent the appliance from delivering the stated network services.
All three requirements-startup priority, delayed shutdown, and host persistence-therefore identify the agent VM configuration.

NEW QUESTION # 64
On a one-node cluster, which updates are supported with LCM?
Answer: D
Explanation:
Life Cycle Manager supports software updates on a single-node cluster but does not support firmware updates in that configuration. Firmware maintenance commonly requires hardware components, host services, or the node itself to be restarted. A conventional multi-node cluster can move workloads and maintain storage availability through other nodes while one node undergoes maintenance. A one-node cluster has no alternate node to preserve cluster services during that process.
"Software only" is broader and more accurate than "AOS only." LCM can manage supported Nutanix software components according to the applicable compatibility and upgrade paths; support is not restricted exclusively to AOS. Inventory is also available as an LCM operation, but option B incorrectly implies that inventory is the only supported capability.
The platform restriction is therefore based on update type: software lifecycle operations are supported, while automated firmware updates are excluded because of the unavoidable service interruption and absence of node-level redundancy. Administrators must still confirm component interoperability and supported upgrade paths before initiating any update. Nutanix explicitly states that LCM is supported for software updates on single-node clusters but not for firmware updates. Reference: Prism 7.5 - Single-Node Cluster Requirements and Limitations . NHCF alignment: LCM capabilities, software maintenance, and cluster-specific limitations.
