NEW QUESTION # 37
What do Nutanix Field Advisories communicate to customers?
Answer: D
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.

NEW QUESTION # 38
How many Controller VMs (CVMs) will a five-node HCI cluster have?
Answer: C
Explanation:
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.

NEW QUESTION # 39
An administrator needs to attach a Volume Group to a Virtual Machine (VM).
When can the administrator complete this task?
Answer: D
Explanation:
A Volume Group is attached to an existing AHV VM through the VM-management or Volume Group modification workflow. The administrator selects the VM for modification, accesses the Volume Groups section, chooses an available Volume Group and completes the attachment. Therefore, option B describes the applicable lifecycle stage.
A Volume Group consists of one or more virtual disks that can be presented to a VM as SCSI block devices.
After attachment, the guest operating system discovers the disks and the administrator can initialize, partition and format them according to application requirements. A Volume Group can also be managed from the Prism Element Volume Group interface, where the Attach to a VM action selects an existing target VM.
A storage policy governs storage behavior and does not itself attach a Volume Group. Migration changes workload placement or location but is not the standard attachment workflow. The initial VM-creation workflow focuses on defining the VM's compute, network and ordinary virtual-disk configuration; attaching an existing Volume Group is handled as a modification after the VM entity exists.

NEW QUESTION # 40
What happens to pinned and Replication Factor 1-enabled VMs on a cluster node that is entering maintenance mode?
Answer: B
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 # 41
Which bond type provides the best utilization of multiple physical NICs for VM traffic throughput?
Answer: B
Explanation:
Balance-tcp provides active-active link utilization through Link Aggregation Control Protocol and is the strongest choice when the objective is to maximize aggregate VM traffic throughput across multiple physical NICs. The mode distributes traffic using flow information, allowing separate TCP flows-including flows originating from the same VM-to use different physical uplinks. This can increase host and VM bandwidth utilization beyond the capacity of a single uplink when sufficient parallel traffic flows exist.
Balance-tcp requires the corresponding physical-switch ports to be configured as a compatible LACP link aggregation group. The AHV bond and upstream switch configuration must agree; otherwise, connectivity or traffic-distribution failures can occur.
Active-Backup uses only one uplink for forwarding while the other remains available for failover, providing redundancy but not simultaneous bandwidth utilization. Balance-slb is also an active-active mode and does not require switch-side LACP, but its source-load-balancing behavior generally associates traffic sources with particular uplinks and cannot distribute an individual flow across links. "No Uplink Bond" supplies neither link aggregation nor bond-level redundancy.
