NEW QUESTION # 67
Refer to the exhibit.
The VM memory-usage graph shows a measured value of approximately 42.95%, with the utilization line remaining inside the blue baseline band.
What should be considered regarding memory usage?
Answer: A
Explanation:
The VM's memory-consumption line remains inside the blue baseline band, so its behavior falls within the learned baseline range. Prism Central uses historical observations and machine-learning analysis to establish the range of values normally expected for an entity and metric. The blue band represents that expected operating range; a value outside the band may be identified as anomalous, depending on duration and deviation.
The displayed value of approximately 42.95% is below 50%, which immediately invalidates option A. More importantly, memory-utilization percentage represents the portion of the VM's allocated memory currently being consumed. It does not mean the host can provide only that percentage of the requested memory, so option C incorrectly interprets utilization as a resource-allocation failure.
The graph also does not provide sufficient evidence to halve the VM's configured memory. Right-sizing requires longer-term utilization, swap activity, workload requirements, peak behavior, and operational policy-not a single observed percentage. Option D therefore recommends an unsupported configuration change.
The correct operational conclusion is limited and precise: the measured behavior is within the VM's learned normal range and is not shown as an anomaly.

NEW QUESTION # 68
Which security option should be implemented to ensure that all intra-cluster communication is secured?
Answer: D
Explanation:
Network Encryption is the security control directed at protecting data while it traverses the network between Nutanix cluster components. It provides cryptographic confidentiality and integrity for supported intra-cluster traffic, preventing captured traffic from being interpreted or modified without detection. In AOS 7.5, the documented intra-cluster data-in-transit encryption capability specifically covers Stargate storage traffic.
Accordingly, the examination wording should be interpreted as asking which option cryptographically secures intra-cluster communications, for which Network Encryption is the only valid choice.
Network Segmentation serves a different purpose. It isolates traffic categories-such as management, backplane, or replication traffic-onto separate networks. Segmentation can reduce exposure and limit broadcast or failure domains, but isolated traffic is not necessarily encrypted. Cluster Lockdown restricts administrative access, particularly access paths involving hosts and Controller VMs; it does not encrypt packets moving between cluster services. "vSwitch Lockdown" is not the relevant Nutanix data-in-transit security mechanism.
The decisive distinction is therefore encryption versus isolation or access restriction. If the requirement is that intercepted traffic must remain unreadable, an encryption capability is required. Segmentation may complement that control, but cannot replace it.

NEW QUESTION # 69
A volume group is a collection of which components?
Answer: A
Explanation:
A Nutanix volume group is a collection of logically related virtual disks, also described as vDisks or volumes.
The group provides block-storage resources that can be attached directly to guest VMs or presented through iSCSI to supported consumers. Grouping the disks allows them to be administered, attached, protected, cloned, and managed as a related storage entity.
A storage pool aggregates physical storage capacity contributed by cluster nodes. Storage containers are logical subdivisions created within a storage pool and hold virtual disks. Consequently, a volume group can use vDisks created on Nutanix storage, but it is not a collection of pools or containers. Controller VMs run the distributed storage and cluster services on individual nodes and are unrelated to volume-group membership.
Each volume group has its own name and UUID, and administrators can add or remove virtual disks according to platform limitations. A group may be associated with one or more consumers depending on the attachment mode and supported use case. This structure is particularly suitable for applications requiring shared block devices, direct iSCSI access, or multiple related application volumes.

NEW QUESTION # 70
What happens to pinned and Replication Factor 1-enabled VMs on a cluster node that is entering maintenance mode?
Answer: A
Explanation:
Pinned VMs and Replication Factor 1-enabled VMs with node affinity cannot be safely live migrated during host maintenance. Prism therefore identifies these VMs as non-migratable and requires them to be powered off before the node can complete entry into maintenance mode.
A pinned VM has a placement constraint binding it to a particular host. Moving it automatically would violate that constraint. An RF1-enabled VM has only one copy of its applicable vDisk data. When that data is associated with the node entering maintenance, another host cannot provide the same resilient storage access expected for an ordinary RF2 or RF3 VM. Powering off prevents the workload from continuing in an unsupported or inaccessible state.
Normal live-migratable VMs are moved to other nodes, subject to available CPU and memory capacity. HA- protected workloads can also be relocated according to the maintenance workflow. Pinned and RF1-affined VMs are handled separately, and Prism prompts the administrator to confirm their shutdown.
Before proceeding, the administrator should identify business impact, obtain an approved outage window, confirm cluster resiliency, and verify that affected applications can be restarted after the node exits maintenance mode.

NEW QUESTION # 71
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.
