質問 # 22
What are two requirements to upgrade Nutanix Guest Tools on a VM? (Choose two.)
正解：A、C
解説：
The VM must be powered on so that the Nutanix Guest Agent and the guest operating system can participate in the NGT installation or upgrade workflow. The NGT software runs inside the guest, so a powered-off VM cannot execute the installer, communicate status, or complete the upgrade operation.
An available IDE or SATA CD-ROM slot is also required because Prism mounts the Nutanix Guest Tools ISO to the VM during configuration, installation, or upgrade. If the VM's virtual CD-ROM is already occupied by another ISO, the NGT media cannot be attached through the expected workflow. Nutanix documentation therefore requires at least one empty supported CD-ROM device. After installation or reconfiguration, supported versions can automatically eject the mounted NGT media.
A DNS entry is not a universal prerequisite for upgrading NGT. Although functional name resolution may support broader management operations, the upgrade requirement is based on VM power state and the ability to mount the NGT ISO. Powering off the VM directly conflicts with the installation requirement. References:

An administrator needs to quickly deploy multiple VMs with identical configurations in Prism Central.
What is the most efficient approach?
正解：A
解説：
A VM template provides a controlled master configuration from which administrators can deploy multiple standardized virtual machines. The template preserves the source VM's supported configuration, including its virtual hardware, operating-system disk, and other deployment properties. Prism Central also supports template versioning, allowing administrators to maintain and update the master image without manually rebuilding every new VM.
Snapshots preserve point-in-time VM data and are primarily intended for recovery, cloning, or data-protection workflows; they are not the principal mechanism for repeatedly provisioning standardized VMs. Categories attach metadata to entities for organization, policy assignment, governance, and automation, but they do not contain a deployable VM configuration. Volume groups provide block-storage resources that can be attached to one or more VMs and therefore do not satisfy the requirement for identical complete VM deployments.
Nutanix documentation describes a VM template as a golden image or master copy used to create VMs in Prism Central. Consequently, deploying from a template minimizes configuration variance and administrative effort. Reference: Prism Central 7.5 - VM Template Management . NHCF alignment: VM lifecycle operations and standardized VM provisioning.
質問 # 24
An administrator needs to ensure that business-critical VMs maintain normal CPU performance.
Which action can the administrator take to generate alerts when VMs are oversubscribed during peak hours?
正解：D
解説：
CPU Ready Time measures the percentage of time that a VM's virtual CPUs are ready to execute but cannot be scheduled on physical CPU resources. It is therefore a direct indicator of processor contention or CPU oversubscription. A VM can show moderate CPU utilization while still suffering poor response times because its vCPUs are waiting for execution time.
Prism Central supports user-defined alert policies based on infrastructure metrics, including VM CPU Ready Time. The administrator can define a threshold and evaluation period so that an alert is generated when scheduling delays exceed an acceptable level during peak demand. This produces proactive notification instead of requiring periodic manual review.
Pulse sends diagnostic information to Nutanix Support but does not create the workload-specific threshold requested. Increasing vCPU allocation without first validating contention may worsen CPU Ready Time because the hypervisor must schedule additional virtual processors. Reviewing average CPU usage is retrospective and does not automatically generate an alert. The most precise control is therefore a custom CPU Ready alert.

質問 # 25
Which component is required to prevent split-brain scenarios on a two-node ROBO cluster?
正解：B
解説：
A two-node cluster lacks the natural majority available in a conventional cluster containing three or more voting members. If communication between its two nodes is interrupted, each node could otherwise interpret the other node as failed and attempt to continue independently. That condition creates a split-brain risk because both sides could consider themselves authoritative.
The external Witness VM supplies the independent arbitration required for the two-node configuration. It is deployed in a separate failure domain and maintains communication with the cluster. During a node or communication failure, witness participation allows the cluster to distinguish the surviving authoritative side and avoid both nodes independently continuing cluster operations. Separating the witness from the two data- bearing nodes is critical because placing all voting components in the same failure domain would undermine the tie-breaking design.
Prism Element is the local cluster-management interface, while Prism Central provides centralized management across clusters. Neither substitutes for an independent quorum witness. Foundation Central supports centralized discovery and deployment activities and does not arbitrate two-node cluster ownership.
Nutanix documentation identifies the external Witness VM as part of the supported two-node ROBO configuration. References: Prism 7.5 - Two-Node Clusters and Witness for Two-Node Clusters . NHCF alignment: valid cluster configurations, availability, and failure handling.
質問 # 26
On which entity is Replication Factor configured?
正解：C
解説：
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.
