NEW QUESTION # 10
How should a license be removed from a cluster for reuse?
Answer: D
Explanation:
A cluster must be unlicensed through the License Manager interface when its allocated entitlement needs to be released for reuse. The unlicensing workflow updates the authoritative licensing state and returns the applicable entitlement or capacity to the organization's available license pool. This is the controlled administrative process recognized by Nutanix licensing services.
Disabling licensed features does not remove the license assignment. It changes feature usage or configuration while leaving the entitlement associated with the cluster. Unregistering a cluster from Prism Central only terminates its centralized management relationship; registration and licensing are independent administrative states. A cluster can therefore be unregistered while still consuming licenses. Deleting a locally generated summary file is equally ineffective because the file reports licensing information but does not constitute the authoritative license allocation.
The administrator should verify connectivity and licensing status, open License Manager, select the applicable cluster, and use the unlicense operation. Any required synchronization with the Nutanix licensing service must be allowed to complete before the entitlement is treated as available elsewhere. This is especially important before decommissioning hardware, rebuilding a cluster, or transferring capacity to another Nutanix environment.

NEW QUESTION # 11
An administrator is troubleshooting a VM that consumes excessive resources and is potentially affecting other VMs.
Which VM Efficiency type refers to this type of VM?
Answer: B
Explanation:
A bully VM consumes an unusually high quantity of shared host resources and may deprive other VMs of the resources required to operate normally. NCM Intelligent Operations identifies this behavior by analyzing sustained metrics such as CPU Ready Time, memory swapping, and host I/O activity. The classification is based on observed resource behavior over time rather than only on the VM's configured size.
A constrained VM has insufficient resources for its own workload demand and may experience performance bottlenecks. An over-provisioned VM has more assigned resources than it regularly uses, creating inefficient capacity allocation without necessarily generating heavy consumption. An inactive VM is powered off or exhibits negligible activity for the defined assessment period. These classifications describe different optimization conditions and do not match a VM actively consuming resources at the expense of neighboring workloads.
After identifying a bully VM, the administrator should inspect its CPU, memory, and storage activity, confirm whether the demand is legitimate, and apply appropriate remediation such as workload tuning, resource resizing, scheduling changes, or storage QoS. Nutanix documentation identifies a bully VM through sustained resource-contention indicators. Reference: NCM Intelligent Operations - Behavioral Learning Tools .

NEW QUESTION # 12
What represents the smallest unit of virtualized data?
Answer: A
Explanation:
Among the listed components, a vDisk is the smallest storage object directly presented through the virtualization layer for use by a VM. A vDisk is created inside a storage container and appears to the guest as an attached disk device. A VM may contain several vDisks for its operating system, application binaries, databases, logs, or other data.
A storage pool is a higher-level aggregation of physical storage resources contributed by cluster nodes. A storage container is a logical subdivision of a storage pool that holds vDisks and applies relevant storage settings. Multiple containers can use the same underlying pool resources. The Extent Store is an AOS storage- layer repository or component used to persist data extents on each node; it is not a user-facing unit of virtualized data.
Although AOS internally divides vDisk data into extents and extent groups, neither "extent" nor "extent group" appears as an answer choice. "Extent Store" refers to the service or repository managing those structures, not the virtualized data object exposed to a workload. Consequently, vDisk is the correct answer within the documented storage hierarchy. Reference: Prism Central - Storage Components . NHCF alignment: storage pools, containers, and virtual disks.
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: A
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.
NHCF/NCA reference: Prism Central monitoring, VM efficiency, resource optimization, and behavioral analysis. Official reference: Behavioral Learning Tools and VM Efficiency , specifically the Dead VM classification.
NEW QUESTION # 14
Which Nutanix storage feature reduces space usage by eliminating identical data blocks?
Answer: C
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.
