NEW QUESTION # 73
Which bond type is the default for newly created AHV clusters?
Answer: D
Explanation:
Active-Backup is the default bond configuration for newly created AHV clusters. In this mode, one physical uplink actively forwards traffic while another eligible uplink remains available as a standby. If the active link fails, AHV moves traffic to the backup link, providing straightforward network redundancy without requiring LACP or a switch-side link-aggregation configuration.
The principal advantage of Active-Backup is operational compatibility. Because only one uplink forwards traffic at a given time, the upstream switch ports do not need to be combined into a link aggregation group.
However, the configuration does not aggregate the bandwidth of multiple physical NICs during normal operation.
Balance-slb provides active-active source load balancing using MAC pinning and can improve aggregate host bandwidth without requiring LACP. Balance-tcp uses active-active LACP and requires matching configuration on the physical switches. Both are deliberately configured alternatives rather than the default.
"No Uplink Bond" would eliminate bond-level redundancy and is not the standard newly created cluster configuration.

NEW QUESTION # 74
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 # 75
An administrator needs to take an immediate snapshot of a single VM.
How should the administrator complete this task?
Answer: B
Explanation:
A manual, immediate snapshot of an individual VM is created from the VM dashboard in Prism Element. The administrator opens the VM table, selects the target VM and invokes the Take Snapshot action. Prism then creates a point-in-time snapshot containing the VM configuration and the supported virtual-disk state.
This procedure is appropriate when the requirement concerns one VM and the snapshot must be taken immediately. Prism Central Data Protection is used for broader protection policies, recovery points, protection schedules and multi-cluster disaster-recovery operations. Those capabilities are valuable for recurring or policy-based protection but are not the direct manual workflow described in the question.
Connecting to a Controller VM is unnecessary and would bypass the supported administrative interface. The Prism Central Images service manages deployable disk images, ISO files and VM image resources; an image is not a point-in-time snapshot of a running VM.
For application-consistent protection, additional guest-side preparation such as Nutanix Guest Tools may be required. A standard manual snapshot, however, is initiated through the selected VM's Prism Element actions.

NEW QUESTION # 76
A VM shows increasing CPU Ready values while overall CPU usage remains unchanged.
What does this behavior suggest?
Answer: B
Explanation:
CPU Ready measures the time during which a virtual CPU is ready to execute but cannot be scheduled on a physical CPU. Increasing CPU Ready while the VM's actual CPU usage remains unchanged indicates that the workload wants processor time but the hypervisor cannot schedule it promptly. This most commonly points to host CPU contention, oversubscription, or effectively exhausted CPU scheduling capacity.
This condition is not evidence that the VM lacks assigned vCPUs. Adding more vCPUs can make the problem worse because the hypervisor may have greater difficulty scheduling a larger virtual CPU configuration. The administrator should examine host CPU utilization, physical-core availability, CPU overcommitment, NUMA alignment, VM sizing, other high-demand VMs, and any CPU limits or affinity constraints.
Memory exhaustion produces different indicators, including swapping, ballooning, or elevated memory wait behavior. A full disk would affect storage capacity and possibly I/O latency but would not directly create CPU Ready time.
The wording "host CPU resources are exhausted" should be understood as unavailable or heavily contended physical scheduling capacity, not necessarily that every processor reports exactly 100% utilization. CPU Ready measures scheduling delay and can reveal contention that VM CPU usage alone does not expose.

NEW QUESTION # 77
An administrator runs a cluster health check and notices that a specific plugin returns a WARN status.
How should the administrator interpret this status?
Answer: A
Explanation:
An NCC WARN status means the health-check plugin returned an unexpected value that requires administrator investigation. Nutanix states that a warning requires user intervention and should be resolved as soon as reasonably possible. A warning is significant, but it is distinct from an NCC failure indicating that the tested aspect is currently unhealthy.
The answer choices deliberately correspond to different NCC result classifications. Option A describes an execution error: the plugin did not run successfully and therefore cannot establish a valid PASS, INFO, WARN, or FAIL result. Option B describes a FAIL condition, where the tested cluster component or state is unhealthy and can require immediate corrective action. Option D describes INFO, in which the plugin returns an expected informational value that cannot be classified as a straightforward pass or failure.
Administrators should read the complete warning output because it normally identifies the affected check, entity, observed value, expected condition, and recommended remediation. The warning should then be correlated with Prism alerts, recent changes, and other NCC results. It must not be ignored merely because the cluster remains operational.
