質問 # 47
How should a license be removed from a cluster for reuse?
正解：C
解説：
A cluster must be unlicensed through the License Manager interface when its allocated entitlement needs to be released for reuse. The unlicensing workflow updates the authoritative licensing state and returns the applicable entitlement or capacity to the organization's available license pool. This is the controlled administrative process recognized by Nutanix licensing services.
Disabling licensed features does not remove the license assignment. It changes feature usage or configuration while leaving the entitlement associated with the cluster. Unregistering a cluster from Prism Central only terminates its centralized management relationship; registration and licensing are independent administrative states. A cluster can therefore be unregistered while still consuming licenses. Deleting a locally generated summary file is equally ineffective because the file reports licensing information but does not constitute the authoritative license allocation.
The administrator should verify connectivity and licensing status, open License Manager, select the applicable cluster, and use the unlicense operation. Any required synchronization with the Nutanix licensing service must be allowed to complete before the entitlement is treated as available elsewhere. This is especially important before decommissioning hardware, rebuilding a cluster, or transferring capacity to another Nutanix environment.

質問 # 48
Refer to the exhibit.
A VM is experiencing poor performance at the storage level.
After reviewing the image, which action should the administrator take?
正解：C
解説：
The exhibit displays the Cluster-wide Controller Latency metric, which represents the average time required for I/O operations to be processed by the cluster's storage controllers. Although the chart contains a latency spike, it does not establish that the cluster lacks SSD capacity or that a Controller VM is undersized. The first diagnostic action should be to determine whether a storage policy, particularly a storage Quality of Service configuration, is limiting the VM.
Storage QoS can impose an IOPS limit on a VM. When the workload reaches that limit, I/O requests are delayed to enforce the configured policy, producing elevated latency even when the physical storage subsystem has sufficient capacity. Nutanix documentation specifically notes that a maximum-IOPS configuration can cause higher latency to appear for the affected VM.
Migrating the VM to another host is unlikely to resolve a policy-enforced storage limit because Nutanix storage is distributed across the cluster. Increasing CVM memory or purchasing additional SSDs would be premature without evidence of sustained resource exhaustion. The appropriate first step is therefore to inspect the VM's applicable storage policy and QoS settings. References: Prism 7.5 - Storage Overview and Prism Central 7.5 - Storage QoS .
質問 # 49
Before physically removing a failing disk from a Nutanix node, what step must be completed in Prism Element?
正解：B
解説：
The disk must first be logically removed from the cluster through Prism Element. The administrator selects the disk, clicks Remove Disk and confirms the action. AOS then migrates any recoverable data away from the device and updates the cluster's storage metadata. The disk must not be physically removed until the process completes and the disk indicator in the hardware diagram turns red.
The red indicator confirms that AOS has finished the supported logical-removal workflow and that the disk is no longer participating as an active storage device. Physically extracting a disk before this state is reached can interrupt data migration, generate additional alerts and reduce cluster resiliency.
The cluster destroy command would destroy the cluster configuration and is entirely inappropriate for component replacement. Shutting down the CVM would unnecessarily remove storage-controller services from the node and can interfere with the evacuation process. Rebooting the AHV host neither removes the disk from AOS metadata nor confirms that data migration has completed.

質問 # 50
A virtual machine needs to be placed on a different storage location within the cluster.
Which task should be performed?
正解：A
解説：
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.
質問 # 51
After deploying a VM, which tool provides additional capabilities, such as file-level restore?
正解：D
解説：
Nutanix Guest Tools is a collection of guest-resident services and utilities that extends the integration between a deployed virtual machine and the Nutanix platform. One of its principal capabilities is Self-Service Restore, also described as file-level restore. When the feature is enabled and NGT is installed, an authorized VM administrator can access files from a Nutanix-protected snapshot without requiring the infrastructure administrator to restore the entire VM.
NGT establishes the guest-side functionality required to expose and use supported recovery services.
Depending on the operating system and enabled components, NGT also supports functions such as application-consistent snapshot coordination and guest communication with the Nutanix platform.
The other tools serve different lifecycle stages. Nutanix X-Ray validates platform performance, resilience and infrastructure behavior. Foundation images physical nodes and creates or expands Nutanix clusters. Nutanix Move migrates workloads from supported source environments to Nutanix AHV or other supported targets.
None of these tools supplies guest-level file recovery after normal VM deployment.
