NEW QUESTION # 47
Which Nutanix storage feature reduces space usage by eliminating identical data blocks?
Answer: B
Explanation:
Deduplication reduces storage consumption by identifying duplicate data blocks and consolidating them so that redundant physical copies do not need to be retained. AOS uses fingerprints to recognize eligible duplicate blocks. Capacity deduplication applies this process to persistent data within a storage container, reducing the physical space consumed by workloads containing substantial repeated content.
Compression is different: it encodes a data block into a smaller representation but does not eliminate identical blocks by replacing them with a shared instance. Erasure Coding reduces the storage overhead associated with maintaining replicated cold data by substituting parity information for certain redundant copies. It is a resilience and capacity-efficiency mechanism, not duplicate-block elimination. Capacity Tiering concerns placement across storage tiers and does not consolidate identical content.
Deduplication should be enabled selectively because fingerprint generation and metadata processing introduce overhead. It is most beneficial for workloads with significant duplicate data, such as appropriate persistent- desktop or full-clone environments. Workloads already using space-efficient Nutanix clones may receive limited additional benefit.
The defining phrase in the question is "eliminating identical data blocks," which is the standard function of deduplication.

NEW QUESTION # 48
An administrator needs to receive an email notification when a specific virtual machine consistently exceeds
90% CPU utilization.
Which feature should be used?
Answer: D
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 # 49
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: B
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 # 50
Refer to the exhibit.
A cluster is showing the alert in the attached image.
What is the recommended method to quickly determine possible causes and corrective actions for this alert?
Answer: A
Explanation:
The alert title is the navigation control used to open the alert details page. That page consolidates the information needed to investigate the condition, including the alert description, severity, creation time, affected entity, possible causes, and recommended corrective actions. Nutanix documentation states that an administrator displays an alert's details by clicking its title.
The Source Entity link leads to information about the affected object-for example, a disk, controller VM, host, or cluster. Entity information may be useful later in the investigation, but it is not the direct route to the alert-specific cause and resolution guidance requested in the question. The selection box merely selects the record for supported bulk or administrative operations. Email Configuration controls alert-notification delivery and does not diagnose the active alert.
Copying the title into a public search engine is also inferior to using the contextual information already maintained in Prism. Search results may apply to different software releases or environmental conditions, whereas the details page is connected to the actual alert instance and entity. Therefore, clicking the alert title is the fastest supported diagnostic path. References: Prism Central - Alerts Summary View and Prism 7.5 - Alert Details .

NEW QUESTION # 51
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.
