NEW QUESTION # 11
Refer to the exhibit.
A VM is experiencing poor performance at the storage level.
After reviewing the image, which action should the administrator take?
Answer: C
Explanation:
The exhibit displays the Cluster-wide Controller Latency metric, which represents the average time required for I/O operations to be processed by the cluster's storage controllers. Although the chart contains a latency spike, it does not establish that the cluster lacks SSD capacity or that a Controller VM is undersized. The first diagnostic action should be to determine whether a storage policy, particularly a storage Quality of Service configuration, is limiting the VM.
Storage QoS can impose an IOPS limit on a VM. When the workload reaches that limit, I/O requests are delayed to enforce the configured policy, producing elevated latency even when the physical storage subsystem has sufficient capacity. Nutanix documentation specifically notes that a maximum-IOPS configuration can cause higher latency to appear for the affected VM.
Migrating the VM to another host is unlikely to resolve a policy-enforced storage limit because Nutanix storage is distributed across the cluster. Increasing CVM memory or purchasing additional SSDs would be premature without evidence of sustained resource exhaustion. The appropriate first step is therefore to inspect the VM's applicable storage policy and QoS settings. References: Prism 7.5 - Storage Overview and Prism Central 7.5 - Storage QoS .
NEW QUESTION # 12
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.

NEW QUESTION # 13
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 # 14
Which statement best describes the requirement for migrating a vDisk between storage containers in Nutanix AOS?
Answer: B
Explanation:
AOS supports live vDisk migration between storage containers while the vDisk remains attached to a powered-on guest VM. The VM does not need to be shut down or deleted. This capability allows administrators to move individual vDisks or all eligible vDisks associated with a VM to a container providing different storage settings.
Storage-container properties can include replication factor, encryption, compression, deduplication, and erasure coding. Migrating a vDisk to another container is therefore a controlled method of changing the storage characteristics applied to that disk without interrupting the running workload.
The operation does not require cluster maintenance mode, and existing snapshots do not universally need to be deleted. However, important restrictions apply. Migration cannot proceed when an applicable Prism Central storage policy is configured for the associated VM. Protected VMs may also need to be removed from their protection domain or protection policy before migration. The target container must have sufficient free capacity, and operations such as cloning, resizing, or taking new snapshots may be blocked while migration is active.
The essential requirement tested is that the VM may remain powered on during the storage-container migration.

NEW QUESTION # 15
What TCP port is required to access the Prism Element GUI and view cluster information?
Answer: B
Explanation:
Prism Element is accessed through HTTPS on TCP port 9440. An administrator connects to the cluster virtual IP address or an appropriate Controller VM address using a URL in the form https:// < cluster-or-CVM- address > :9440. After authentication, Prism Element provides cluster-level information and administrative functions for hardware, storage, VMs, alerts, health, upgrades, and configuration.
TCP 443 is the conventional HTTPS port used by many web applications, but it is not the standard Prism Element web-console port tested here. Ports 8080 and 8443 are also commonly used by other web applications or management interfaces but do not represent the default Prism Element GUI endpoint.
Port 9440 is also important for several Nutanix management-plane communications. For example, connectivity between Prism Central and registered Prism Element clusters requires access to the Controller VM or cluster virtual IP addresses on this port. Firewalls, access-control lists, proxy configurations, and security devices must therefore permit the required traffic between authorized management systems.
The use of HTTPS provides encrypted browser communication, but the administrator should still deploy trusted certificates, restrict management-network exposure, and apply role-based access controls.
