33. Frage
On which entity is Replication Factor configured?
Antwort: C
Begründung:
Replication Factor is configured on a storage container. It determines how many copies of the data associated with that container are maintained across the Nutanix distributed storage fabric. The official Prism 7.5 definition states that replication factor is the number of copies of data maintained on a storage container within a cluster. For example, RF2 maintains two copies, whereas RF3 maintains three copies and consequently requires a cluster capable of providing the corresponding fault-tolerance level.
A storage pool aggregates physical storage resources, but it does not independently establish the replication policy for guest data. A protection domain defines which entities are protected and controls snapshot or replication schedules for disaster recovery; it is not the administrative location for configuring local data-copy count. "Replication Policy" is therefore a distractor representing data-protection behavior rather than an AOS storage entity.
Replication factor also affects usable capacity because additional copies consume physical storage.
Administrators must therefore align the container's replication factor with the cluster's available fault domains and required resilience. Prism requires RF3 to be configured individually for the applicable containers after the cluster supports the necessary fault-tolerance level.

34. Frage
An administrator needs to take an immediate snapshot of a single VM.
How should the administrator complete this task?
Antwort: B
Begründung:
A manual, immediate snapshot of an individual VM is created from the VM dashboard in Prism Element. The administrator opens the VM table, selects the target VM and invokes the Take Snapshot action. Prism then creates a point-in-time snapshot containing the VM configuration and the supported virtual-disk state.
This procedure is appropriate when the requirement concerns one VM and the snapshot must be taken immediately. Prism Central Data Protection is used for broader protection policies, recovery points, protection schedules and multi-cluster disaster-recovery operations. Those capabilities are valuable for recurring or policy-based protection but are not the direct manual workflow described in the question.
Connecting to a Controller VM is unnecessary and would bypass the supported administrative interface. The Prism Central Images service manages deployable disk images, ISO files and VM image resources; an image is not a point-in-time snapshot of a running VM.
For application-consistent protection, additional guest-side preparation such as Nutanix Guest Tools may be required. A standard manual snapshot, however, is initiated through the selected VM's Prism Element actions.

35. Frage
An administrator needs to receive an email notification when a specific virtual machine consistently exceeds
90% CPU utilization.
Which feature should be used?
Antwort: C
Begründung:
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.

36. Frage
A volume group is a collection of which components?
Antwort: B
Begründung:
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.

37. Frage
What is the purpose of NCC?
Antwort: B
Begründung:
Nutanix Cluster Check is cluster-resident diagnostic software that evaluates the health, configuration, and operational state of a Nutanix environment. NCC includes plugins and checks covering cluster services, storage, networking, hardware, hypervisor integration, data protection, security-related settings, and other platform dependencies. Its results identify passed checks, warnings, failures, and conditions that require administrative attention.
NCC is used during routine health validation, before and after upgrades, and when troubleshooting an active problem. Keeping NCC current is important because newer releases contain updated checks for current platform versions, supported configurations, and known failure conditions. Administrators can run broad check groups or individual plugins from Prism and the Controller VM command line.
VM migration between hypervisors is performed through Nutanix Move. Network microsegmentation is provided through Flow Network Security and related policy controls. Cluster imaging and deployment are handled through Foundation or Foundation Central. None of those functions represents NCC's role.
Nutanix defines NCC as software that helps diagnose cluster health and identify configurations qualified and recommended by Nutanix. Reference: Nutanix Cluster Check Guide . NHCF alignment: performing health checks, interpreting results, and preparing a cluster for maintenance or support investigation.
