NEW QUESTION # 72
A VM is experiencing delays even though its own CPU usage appears low.
Which metric should be checked to identify scheduling issues?
Answer: A
Explanation:
CPU Ready measures the time during which a virtual CPU is prepared to execute but is waiting for the hypervisor to schedule it on a physical processor. A VM can therefore report low apparent CPU consumption while still responding slowly: its workload is not continuously executing because the assigned vCPUs are waiting for physical CPU time.
Elevated CPU Ready commonly indicates physical CPU contention, excessive vCPU allocation, an unfavorable vCPU-to-core ratio, or competition from other VMs on the host. The administrator should correlate CPU Ready with host CPU utilization, VM sizing, the number of runnable vCPUs, and workload behavior. Assigning additional vCPUs without confirming the cause can worsen scheduling delays because the hypervisor may need to coordinate more virtual processors.
Disk capacity measures available storage space and does not identify processor scheduling latency. Memory usage can reveal pressure, swapping, or insufficient guest memory, but it does not directly represent time spent waiting for CPU scheduling. Snapshot size relates to retained point-in-time storage data and is unrelated to hypervisor CPU dispatch. Nutanix identifies CPU Ready Time as the percentage of CPU wait time, making it the appropriate metric. Reference: Nutanix Intelligent Operations - VM Details and CPU Ready Time .

NEW QUESTION # 73
Which component is required to prevent split-brain scenarios on a two-node ROBO cluster?
Answer: C
Explanation:
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.
NEW QUESTION # 74
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: B
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 # 75
Which action will ensure AHV automatically assigns an IP address to a VM?
Answer: B
Explanation:
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.

NEW QUESTION # 76
What do Nutanix Field Advisories communicate to customers?
Answer: A
Explanation:
Nutanix Field Advisories communicate technically significant issues identified in deployed environments. An advisory typically describes the affected products or versions, the conditions under which the issue occurs, its potential operational impact and any available workaround, mitigation or permanent resolution. Option D therefore represents the advisory's purpose accurately.
Field Advisories are part of the operational knowledge used by Nutanix Support and Insights. Insights discoveries can compare cluster telemetry and configuration information against known Field Advisories to determine whether a particular environment may be exposed. Where possible, the resulting discovery includes recommended corrective action or directs the administrator to the relevant upgrade, configuration change or support process.
Product announcements and pricing information are commercial communications, not Field Advisories.
Certified hardware information is maintained through compatibility lists and platform qualification resources.
New-cluster installation procedures belong in Foundation, deployment and installation documentation.
Administrators should review applicable Field Advisories during routine health reviews and before major maintenance because an advisory can affect upgrade selection, risk assessment and remediation priority.
