NEW QUESTION # 86
During a routine cluster review, an administrator observes that an NCC check has returned the following status:
ERR: The plugin timed out
What does this status indicate about the health check?
Answer: A
Explanation:
An ERR status means that the NCC plugin failed to execute successfully. In this case, the plugin exceeded its allowed execution period and timed out. Because the check did not complete, NCC cannot determine whether the tested cluster component is healthy or unhealthy. Option C is therefore the accurate interpretation.
ERR must not be treated as equivalent to FAIL. A FAIL result indicates that the check executed and identified a condition that did not satisfy the required health criteria. By contrast, ERR describes a problem with the health-check execution itself. The administrator should review the accompanying message, verify the applicable services and connectivity, and rerun the check. Persistent execution errors may require collecting NCC logs or engaging Nutanix Support.
A warning or an unexpected but noncritical condition is represented differently. INFO supplies contextual information that does not constitute a failure, while WARN identifies a condition requiring review. The timeout result cannot validate the cluster's state, so the underlying area remains unconfirmed until the check completes successfully.

NEW QUESTION # 87
An organization has determined that a specific NCC check can be disregarded and does not want to see the alert.
Where would an administrator turn off the relevant NCC check?
Answer: A
Explanation:
The relevant NCC check should be disabled from the Prism Element web console. For a Prism Element cluster, administrators manage NCC checks through the Health dashboard. The Actions menu provides check- management functions, including selecting individual checks and controlling whether they remain enabled.
This is different from acknowledging or resolving an existing alert. Acknowledgement records that the alert has been reviewed, while disabling the underlying check prevents it from continuing to run and generate the unwanted condition. The administrator should disable a check only after confirming that it is genuinely inapplicable or that Nutanix has documented the condition as safe to disregard.
Nutanix states that after a check is disabled through the Prism web console, it cannot be run through the NCC command line until it is re-enabled in the web console. Therefore, running a command on a CVM is not the correct method for managing the persisted disabled state presented in the question. Prism Central can initiate broader troubleshooting and cluster-check workflows, but the relevant per-cluster check configuration is maintained through Prism Element.
The disabled check and the justification should be documented because suppressing a valid health check can conceal operational risk.

NEW QUESTION # 88
What is the default time that a Nutanix cluster will run an LCM auto inventory and auto update?
Answer: B
Explanation:
The default scheduled time for LCM automatic inventory and automatic update activity is 3:00 AM. This setting is used when Auto Inventory and Auto Update are enabled for a connected site. Administrators can modify the schedule when 3:00 AM does not align with the organization's operational or maintenance requirements.
Automatic inventory refreshes LCM's knowledge of installed software and firmware components and retrieves current update metadata from the configured Nutanix source. Nutanix also specifies that if an inventory operation has already completed within the preceding 12 hours, LCM can skip the scheduled auto- inventory because its component information remains sufficiently current. Automatic update in this setting applies to the supported automatically managed component-particularly Nutanix Cluster Check-rather than authorizing every available AOS, AHV, or firmware upgrade without administrator review.
The other answer choices do not represent the documented default. However, administrators should treat 3:00 AM as a configurable platform default rather than an assumed maintenance window. They must verify the configured schedule, time context, Internet connectivity, and update policy for the specific environment.

NEW QUESTION # 89
An administrator needs to decrease the number of CPUs assigned to a VM.
What is the first step?
Answer: A
Explanation:
The VM must be powered off before the administrator can reduce its CPU allocation. CPU hot-plug capabilities permit supported guest operating systems to receive additional virtual CPU resources while running, but they do not provide a supported mechanism for removing active processors from a powered-on VM. Nutanix documentation states that the number of CPUs cannot be decreased while the VM is powered on.
After shutting down the guest cleanly and confirming that the VM is off, the administrator can edit the VM configuration, reduce the required vCPU count or associated CPU topology, save the change, and restart the VM. The proposed configuration must remain valid-for example, the relationship between sockets, vCPUs, and cores must be supported.
Enabling Hot-Add addresses CPU expansion rather than reduction. Nutanix Guest Tools supplies guest integration and operational capabilities but does not override hypervisor restrictions on CPU removal. A snapshot may be useful as an optional change-control precaution, but it does not make CPU reduction possible and is not the required first step.
The technically necessary action is therefore to power off the VM. Reference: AHV - Virtual Machine Memory and CPU Hot-Plug Configurations . NHCF alignment: modifying VM compute resources and understanding hot-plug limitations.
NEW QUESTION # 90
How many Controller VMs (CVMs) will a five-node HCI cluster have?
Answer: C
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.
