質問 # 42
What represents the smallest unit of virtualized data?
正解：A
解説：
Among the listed components, a vDisk is the smallest storage object directly presented through the virtualization layer for use by a VM. A vDisk is created inside a storage container and appears to the guest as an attached disk device. A VM may contain several vDisks for its operating system, application binaries, databases, logs, or other data.
A storage pool is a higher-level aggregation of physical storage resources contributed by cluster nodes. A storage container is a logical subdivision of a storage pool that holds vDisks and applies relevant storage settings. Multiple containers can use the same underlying pool resources. The Extent Store is an AOS storage- layer repository or component used to persist data extents on each node; it is not a user-facing unit of virtualized data.
Although AOS internally divides vDisk data into extents and extent groups, neither "extent" nor "extent group" appears as an answer choice. "Extent Store" refers to the service or repository managing those structures, not the virtualized data object exposed to a workload. Consequently, vDisk is the correct answer within the documented storage hierarchy. Reference: Prism Central - Storage Components . NHCF alignment: storage pools, containers, and virtual disks.
質問 # 43
After deploying a VM, which tool provides additional capabilities, such as file-level restore?
正解：B
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.

質問 # 44
On which entity is Replication Factor configured?
正解：C
質問 # 45
An administrator is working with Nutanix Support and has been asked to submit the NCC logs for further review.
How should the administrator gather the logs for the support case?
正解：B
解説：
The supported Prism Element workflow for gathering diagnostic data is the Collect Logs feature. From the Health dashboard, the administrator opens the Actions menu, selects Collect Logs, identifies the relevant nodes and components, specifies the required time range or collection parameters, and starts the log-collection task. The resulting archive can then be associated with or uploaded for the Nutanix Support case.
Pulse is a proactive support and telemetry capability that periodically provides diagnostic system information to Nutanix. It does not automatically transmit every detailed NCC or component log required for a specific investigation. Nutanix documentation notes that when Pulse data is insufficient for diagnosis, Support may request a separate diagnostic log collection.
"Export Logs" and "Download Logs in Prism Central" are not the documented names of the NCC collection workflow described in the question. The explicit Health dashboard operation is Collect Logs. This process also allows the administrator to control which nodes and components are included, preventing irrelevant data from unnecessarily enlarging the support bundle. Reference: Prism 7.5 - Collecting Logs Using Prism Element . NHCF alignment: collecting support data, using health functions, and collaborating with Nutanix Support.
質問 # 46
A VM is experiencing delays even though its own CPU usage appears low.
Which metric should be checked to identify scheduling issues?
正解：C
解説：
CPU Ready measures the time during which a virtual CPU is prepared to execute but is waiting for the hypervisor to schedule it on a physical processor. A VM can therefore report low apparent CPU consumption while still responding slowly: its workload is not continuously executing because the assigned vCPUs are waiting for physical CPU time.
Elevated CPU Ready commonly indicates physical CPU contention, excessive vCPU allocation, an unfavorable vCPU-to-core ratio, or competition from other VMs on the host. The administrator should correlate CPU Ready with host CPU utilization, VM sizing, the number of runnable vCPUs, and workload behavior. Assigning additional vCPUs without confirming the cause can worsen scheduling delays because the hypervisor may need to coordinate more virtual processors.
Disk capacity measures available storage space and does not identify processor scheduling latency. Memory usage can reveal pressure, swapping, or insufficient guest memory, but it does not directly represent time spent waiting for CPU scheduling. Snapshot size relates to retained point-in-time storage data and is unrelated to hypervisor CPU dispatch. Nutanix identifies CPU Ready Time as the percentage of CPU wait time, making it the appropriate metric. Reference: Nutanix Intelligent Operations - VM Details and CPU Ready Time .
