NEW QUESTION # 54
What would cause storage compression to become automatically disabled?
Answer: D
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.

NEW QUESTION # 55
An administrator needs to receive an email notification when a specific virtual machine consistently exceeds
90% CPU utilization.
Which feature should be used?
Answer: C
Explanation:
A Custom Alert Policy should be created for the target VM's CPU-utilization metric. The policy can define the VM entity, the CPU threshold of 90%, the duration or evaluation condition required to establish sustained utilization, and the alert severity. Prism Central evaluates enabled user-defined alert policies periodically and generates an alert when the configured conditions are satisfied.
Email notification additionally requires alert-email configuration. The administrator must define valid SMTP settings or the applicable notification channel and ensure the intended recipients receive alerts matching the policy. This separates metric evaluation from notification delivery: the Custom Alert Policy detects the condition, while alert-email settings determine how the resulting alert is distributed.
A storage-container quota monitors storage capacity rather than VM CPU utilization. Pulse transfers diagnostic telemetry to Nutanix Support and does not provide customer-defined VM CPU threshold policies.
A Recovery Plan orchestrates disaster-recovery operations and is unrelated to performance-alert evaluation.
Using a sustained-duration condition is important because a brief CPU spike does not necessarily indicate a capacity or performance problem. The policy should reflect how long utilization must exceed 90% before notification is justified.

NEW QUESTION # 56
Which protocols does the Network Visualizer leverage to discover and display network connections and statistics?
Answer: D
Explanation:
Nutanix Network Visualizer uses Link Layer Discovery Protocol or Cisco Discovery Protocol to determine the relationship between an AHV host interface and the corresponding first-hop physical-switch port. It can then use configured SNMP access to retrieve additional switch, port and operational statistics. The combined protocol set in option C therefore enables both topology discovery and the display of useful physical-network information.
LLDP is vendor-neutral, while CDP is primarily associated with Cisco networking equipment. Either protocol can advertise the local port identity needed to construct the topology mapping. SNMP supplements that discovery by providing management-plane information obtained from supported switches. Nutanix documentation notes that when LLDP or CDP information is unavailable, SNMP data may be used to assist mapping, although complete and accurate visualization depends on supported devices and appropriate configuration.
BGP and OSPF exchange routing information; they are not the protocol set used by Network Visualizer for host-to-switch discovery. DHCP and PXE provide address allocation and network boot services. STP prevents Layer 2 loops, while VTP distributes VLAN information in certain Cisco environments.

NEW QUESTION # 57
What crucial step must be taken before successfully stopping a Nutanix cluster?
Answer: A
Explanation:
All guest virtual machines must be shut down before stopping a Nutanix cluster. A cluster shutdown terminates the AOS services provided by the Controller VMs and ultimately shuts down the hypervisor hosts.
Leaving user workloads running would expose those VMs to abrupt power loss, interrupted write operations and possible application or filesystem corruption.
The supported sequence begins with a controlled shutdown of the guest operating systems. Administrators should verify that no user VMs remain powered on, check cluster health and then execute the supported cluster-stop procedure. The cluster process coordinates the shutdown of AOS services and Controller VMs; therefore, administrators must not manually power off every CVM as the first action.
Disabling the Remote Support Tunnel has no bearing on the safe shutdown of storage and compute services.
Protection domains generally do not need to be disabled for an ordinary cluster shutdown, although synchronous-replication configurations can require additional site-specific preparation.

NEW QUESTION # 58
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: D
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.
