NEW QUESTION # 74
An administrator needs to ensure that business-critical VMs maintain normal CPU performance.
Which action can the administrator take to generate alerts when VMs are oversubscribed during peak hours?
Answer: D
Explanation:
CPU Ready Time measures the percentage of time that a VM's virtual CPUs are ready to execute but cannot be scheduled on physical CPU resources. It is therefore a direct indicator of processor contention or CPU oversubscription. A VM can show moderate CPU utilization while still suffering poor response times because its vCPUs are waiting for execution time.
Prism Central supports user-defined alert policies based on infrastructure metrics, including VM CPU Ready Time. The administrator can define a threshold and evaluation period so that an alert is generated when scheduling delays exceed an acceptable level during peak demand. This produces proactive notification instead of requiring periodic manual review.
Pulse sends diagnostic information to Nutanix Support but does not create the workload-specific threshold requested. Increasing vCPU allocation without first validating contention may worsen CPU Ready Time because the hypervisor must schedule additional virtual processors. Reviewing average CPU usage is retrospective and does not automatically generate an alert. The most precise control is therefore a custom CPU Ready alert.

NEW QUESTION # 75
What happens to pinned and Replication Factor 1-enabled VMs on a cluster node that is entering maintenance mode?
Answer: B
Explanation:
Pinned VMs and Replication Factor 1-enabled VMs with node affinity cannot be safely live migrated during host maintenance. Prism therefore identifies these VMs as non-migratable and requires them to be powered off before the node can complete entry into maintenance mode.
A pinned VM has a placement constraint binding it to a particular host. Moving it automatically would violate that constraint. An RF1-enabled VM has only one copy of its applicable vDisk data. When that data is associated with the node entering maintenance, another host cannot provide the same resilient storage access expected for an ordinary RF2 or RF3 VM. Powering off prevents the workload from continuing in an unsupported or inaccessible state.
Normal live-migratable VMs are moved to other nodes, subject to available CPU and memory capacity. HA- protected workloads can also be relocated according to the maintenance workflow. Pinned and RF1-affined VMs are handled separately, and Prism prompts the administrator to confirm their shutdown.
Before proceeding, the administrator should identify business impact, obtain an approved outage window, confirm cluster resiliency, and verify that affected applications can be restarted after the node exits maintenance mode.

NEW QUESTION # 76
Which Nutanix support case priority level is used for a non-critical loss of use with medium to low impact?
Answer: D
Explanation:
Nutanix classifies this condition as Priority 3, or P3. The official support definition describes P3 as a normal- priority case involving a minor inconvenience or an occasional, non-critical issue that requires resolution but has not materially reduced productivity. Its defining language includes: "A non-critical loss of use with medium to low impact." A short-term workaround is generally available.
P1 is reserved for emergency conditions in which production systems are unavailable or unusable, critical functionality is down, significant data loss is occurring or threatened, and no procedural workaround exists.
P2 applies when production remains available but experiences major degradation or the loss of important functionality, materially affecting part of the organization's operations. P4 covers low-impact informational requests, including questions about documentation, procedures, configuration, or account setup.
The scenario uses the defining P3 wording rather than merely describing a general support question. It therefore cannot be reduced to P4, while its non-critical and limited-impact characteristics exclude P1 and P2.
The correct priority is C. Reference: Nutanix Support Policies and Priority Definitions . NHCF alignment:

NEW QUESTION # 77
What is the purpose of NCC?
Answer: A
Explanation:
Nutanix Cluster Check is cluster-resident diagnostic software that evaluates the health, configuration, and operational state of a Nutanix environment. NCC includes plugins and checks covering cluster services, storage, networking, hardware, hypervisor integration, data protection, security-related settings, and other platform dependencies. Its results identify passed checks, warnings, failures, and conditions that require administrative attention.
NCC is used during routine health validation, before and after upgrades, and when troubleshooting an active problem. Keeping NCC current is important because newer releases contain updated checks for current platform versions, supported configurations, and known failure conditions. Administrators can run broad check groups or individual plugins from Prism and the Controller VM command line.
VM migration between hypervisors is performed through Nutanix Move. Network microsegmentation is provided through Flow Network Security and related policy controls. Cluster imaging and deployment are handled through Foundation or Foundation Central. None of those functions represents NCC's role.
Nutanix defines NCC as software that helps diagnose cluster health and identify configurations qualified and recommended by Nutanix. Reference: Nutanix Cluster Check Guide . NHCF alignment: performing health checks, interpreting results, and preparing a cluster for maintenance or support investigation.
NEW QUESTION # 78
An administrator is provisioning a new Linux virtual machine.
Which timezone is recommended for this VM?
Answer: B
Explanation:
UTC is the recommended timezone selection when creating a Linux VM on AHV. Nutanix specifically states that the real-time clock of a Linux VM must operate in UTC. Selecting the UTC timezone ensures that the guest's hardware-clock interpretation is consistent with Linux conventions and avoids time shifts caused by local timezone or daylight-saving changes.
Time consistency is essential for authentication, application logging, distributed databases, monitoring, certificate validation and event correlation. The guest operating system can still display a regional timezone to users at the application or operating-system level while maintaining its underlying hardware clock in UTC.
"Local" can cause the guest to interpret the virtual hardware clock according to a regional offset, producing incorrect timestamps after migration, reboot or daylight-saving transitions. "Cluster" is not a supported timezone designation for this VM setting. RTC means real-time clock and describes the clock mechanism rather than a selectable geographic timezone.
The VM should also use a reliable NTP source after deployment so its operating-system time remains synchronized.
