NEW QUESTION # 54
An administrator attempts to run a specific Nutanix Cluster Check (NCC) plugin from the Controller VM command line, but the check will not execute. The administrator discovers that this specific check was recently disabled by another user in the Prism web console.
Which action must the administrator take to successfully run this check from the command line?
Answer: C
Explanation:
When an NCC plugin has been administratively disabled, a normal command-line execution respects that disabled state and skips the plugin. To run that specific check without permanently changing its configured status in Prism, the administrator must append the --force_run=True argument to the NCC command. The flag instructs NCC to execute the selected plugin despite its disabled configuration.
Restarting the cluster health service does not change the plugin's enablement state and introduces an unnecessary service operation. Re-enabling the check in Prism Element could also permit execution, but it changes the persistent configuration and is not required when the objective is to run the check once from the command line. Running ncc health_checks run_all does not override the disabled state; the disabled plugin can still be omitted from the complete check set.
NCC supports running complete check groups, individual plugins, and command options that modify execution behavior. Administrators should use forced execution deliberately because a check may have been disabled due to environmental applicability, a known issue, or support guidance. Reference: NCC 5.2 - NCC Usage .

What do Nutanix Field Advisories communicate to customers?
Answer: B
Explanation:
Nutanix Field Advisories communicate technically significant issues identified in deployed environments. An advisory typically describes the affected products or versions, the conditions under which the issue occurs, its potential operational impact and any available workaround, mitigation or permanent resolution. Option D therefore represents the advisory's purpose accurately.
Field Advisories are part of the operational knowledge used by Nutanix Support and Insights. Insights discoveries can compare cluster telemetry and configuration information against known Field Advisories to determine whether a particular environment may be exposed. Where possible, the resulting discovery includes recommended corrective action or directs the administrator to the relevant upgrade, configuration change or support process.
Product announcements and pricing information are commercial communications, not Field Advisories.
Certified hardware information is maintained through compatibility lists and platform qualification resources.
New-cluster installation procedures belong in Foundation, deployment and installation documentation.
Administrators should review applicable Field Advisories during routine health reviews and before major maintenance because an advisory can affect upgrade selection, risk assessment and remediation priority.

NEW QUESTION # 56
An administrator wants Prism Central to display CPU utilization for five virtual machines over the past 24 hours.
Which chart type should be used?
Answer: C
Explanation:
A Metric Chart is designed to display one selected performance metric across one or more entities. In this scenario, CPU utilization is the single metric, while the five virtual machines are the multiple entities being compared. The chart's time range can be set to the previous 24 hours so that utilization trends and differences among the VMs are visible over a common interval.
Nutanix distinguishes a Metric Chart from an Entity Chart by what remains constant. A Metric Chart fixes the metric and permits multiple entities. An Entity Chart fixes the entity and displays one or more metrics for that entity. Therefore, if the administrator wanted to examine CPU utilization, memory utilization, IOPS, and network throughput for one VM, an Entity Chart would be appropriate. That is not the requirement presented here.
A Gantt chart represents task duration or scheduled activity along a timeline and is not the Prism performance- comparison chart for this use case. A pie chart represents composition at a point in time and is unsuitable for displaying historical CPU behavior across a 24-hour period.
The determining relationship is therefore one metric-CPU utilization-mapped to five VM entities, which directly matches the Metric Chart definition.

NEW QUESTION # 57
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 # 58
What would cause storage compression to become automatically disabled?
Answer: B
Explanation:
Nutanix AOS automatically disables compression when metadata usage becomes high. The Prism 7.5 storage documentation explicitly identifies this condition and states that an alert is generated when automatic disablement occurs. Consequently, option D is the verified answer, replacing the supplied answer A.
Compression requires AOS metadata resources to track compressed extents and the associated data layout. If metadata consumption reaches a protective threshold, continuing compression could place additional pressure on the metadata services required for normal storage operation. AOS therefore prioritizes platform stability and metadata availability by disabling compression and notifying the administrator. The corresponding health alert should be investigated to determine why metadata usage has increased and whether workload characteristics or another storage condition requires remediation.
High write activity may increase storage workload and influence when post-process compression can execute, but it is not the documented automatic-disable trigger in this question. High reads similarly do not directly cause compression to be disabled. High physical-capacity consumption generates its own capacity warnings and corrective requirements but is distinct from the metadata threshold governing compression.
