NEW QUESTION # 13
An administrator is troubleshooting resource availability within the cluster. As part of the troubleshooting, the administrator wants to build a list of powered-off VMs on the Nutanix cluster.
In order for these VMs to be listed in the Prism Central VM Efficiency widget, how many days must the VMs be powered off to be considered a Dead VM?
Answer: B
Explanation:
Prism Central classifies a virtual machine as a Dead VM after it has remained powered off for at least 30 days. The VM Efficiency capability uses this duration to distinguish temporarily stopped workloads from VMs that are sufficiently inactive to justify administrative review. Consequently, a VM powered off for only
5 or 15 days does not meet the classification threshold, while 45 days exceeds-but does not define-the required minimum.
A Dead VM is not automatically deleted. The classification is an efficiency finding intended to identify resources that may no longer be required. Even while powered off, the VM can continue consuming storage through its virtual disks, snapshots, recovery points, and associated configuration objects. Administrators should therefore validate application ownership, retention requirements, protection policies, and compliance obligations before deleting or archiving it.
The VM Efficiency widget is part of Prism's broader behavioral and capacity-optimization functionality.
Other inefficiency classifications can identify overprovisioned or constrained VMs by evaluating historical resource behavior. The 30-day rule is specifically associated with the powered-off Dead VM condition and should not be confused with utilization-based efficiency findings.

NEW QUESTION # 14
Which Nutanix license tier includes the ability to enable microsegmentation using Flow Network Security?
Answer: B
Explanation:
Flow Network Security microsegmentation is included with the NCI Ultimate feature set. Microsegmentation applies policy-based controls between protected workloads, allowing administrators to restrict east-west traffic according to categories, application tiers and defined security requirements. Because this is an infrastructure networking and security capability, its core entitlement is associated with Nutanix Cloud Infrastructure rather than Nutanix Cloud Manager.
The official Nutanix software-options matrix distinguishes between inclusion and add-on availability. NCI Ultimate includes microsegmentation. NCI Pro can support the capability when the applicable Security add- on is purchased, but the base NCI Pro tier alone does not include that entitlement. NCI Starter does not provide the required microsegmentation entitlement. NCM Ultimate includes advanced cloud-management, governance and security-compliance functions, but it does not replace the NCI entitlement needed to enforce Flow Network Security policies on protected workloads.
Therefore, among the listed standalone tiers, NCI Ultimate is the tier that includes the ability directly. This distinction is important in exam questions: a feature being available as an add-on to a tier is not equivalent to being included in the base tier.

NEW QUESTION # 15
On an AHV host, what is the factory-configured default native Linux bridge?
Answer: C
Explanation:
The factory configuration of an AHV host includes a native Linux bridge named virbr0. This bridge is separate from the Open vSwitch components used for normal AHV workload and infrastructure networking.
Administrators should preserve the factory-defined bridge unless a specific Nutanix procedure instructs otherwise.
The similarly named components in the other options serve different purposes. br0 is the factory-configured default Open vSwitch bridge. It contains the physical uplink interfaces and internal ports used by the AHV networking architecture. vs0 is the default AHV virtual-switch configuration associated with br0; it is a logical virtual-switch object rather than a native Linux bridge. ovsbr0 is not the factory-default bridge name in the documented AHV configuration.
This distinction is operationally important when interpreting commands such as ovs-vsctl, Linux bridge utilities, interface listings, or network-troubleshooting output. Confusing virbr0 with br0 can lead an administrator to modify the wrong networking component and potentially disrupt host, CVM, or guest connectivity. Nutanix documentation explicitly identifies the native Linux bridge as virbr0. Reference: AHV

NEW QUESTION # 16
What would cause storage compression to become automatically disabled?
Answer: B
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 # 17
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.
