質問 # 58
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?
正解：C
解説：
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.

Which action will ensure AHV automatically assigns an IP address to a VM?
正解：B
解説：
AHV provides integrated IP Address Management through a managed virtual network. Enabling IPAM on the VM's existing virtual network and defining a DHCP address pool allows AHV to intercept the guest's DHCP request and allocate an available address from that pool. During VM or vNIC configuration, the administrator can then select DHCP assignment, allowing the platform to manage address allocation automatically.
Option B is the complete action for converting the VM's current network into an IPAM-capable network.
Although an IPAM-enabled network can also be created from the beginning, option C creates a different network and does not, by itself, ensure that the existing VM is connected to it. Option A may provide conventional external DHCP, but it does not constitute AHV-managed IPAM. Option D is invalid because the Controller VM is not intended to be repurposed as an administrator-configured DHCP server.
The DHCP pool must contain valid addresses for the subnet and exclude reserved infrastructure addresses.
The VM must also be attached to that managed network and configured for DHCP; otherwise, AHV cannot complete the allocation.

質問 # 60
Where should a support ticket be opened with Nutanix?
正解：B
解説：
A Nutanix support ticket should be opened from the case-management area of the Nutanix Smart Support or Support Portal by navigating to Cases and selecting the option to create or open a case. This location provides access to existing cases, entitlement and asset information, severity selection, problem descriptions, and diagnostic uploads.
The Account area is used for account-related administration and is not the normal navigation path for submitting a technical case. Prism Element also does not provide a User-menu path named Create Case, eliminating option A.
Current Prism Central releases can expose support-case functionality, but the documented navigation is through the Help icon and Create Support Case-not through the User menu stated in option C. Therefore, option C is incorrect as written even though Prism Central may integrate with Nutanix Support.
When creating the case, the administrator should provide the affected cluster or asset, AOS and hypervisor versions, severity, business impact, recent changes, timestamps, and relevant logs. Accurate case classification and diagnostic information reduce investigation time.

質問 # 61
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 # 62
How many Controller VMs (CVMs) will a five-node HCI cluster have?
正解：A
解説：
A conventional five-node Nutanix HCI cluster has five Controller VMs-one CVM running on each node.
AOS operates as a distributed storage and data-services system rather than relying on a single centralized storage controller. The per-node CVM architecture provides local access to the node's storage devices while cooperating with the CVMs on the other nodes to form the distributed AOS storage fabric.
The CVMs collectively provide services associated with data placement, replication, metadata, caching, compression, deduplication, snapshots, and cluster storage management. If a CVM becomes unavailable, the host can access storage services through another CVM, subject to cluster health and connectivity. The remaining CVMs also maintain the distributed cluster services required for continued operation.
The number of CVMs therefore normally matches the number of HCI nodes: three nodes produce three CVMs, four nodes produce four, and five nodes produce five. The count does not represent the replication factor or the number of simultaneously tolerated failures.
Compute-only nodes are a specific exception because they do not run a CVM. However, the question explicitly describes a five-node HCI cluster, so each node contributes storage and runs a Controller VM.
