NEW QUESTION # 57
Monitoring data shows stable CPU and memory usage, but a user VM remains slow.
Which area should be investigated next?
Answer: C
Explanation:
Once CPU consumption, CPU contention and memory utilization have been reviewed and found stable, storage latency becomes the next relevant performance domain. A VM can have adequate compute resources yet remain slow because guest read or write operations are waiting for the storage path. High latency may arise from workload contention, abnormal I/O patterns, a storage-controller issue, or an underlying infrastructure condition.
Prism exposes VM and infrastructure metrics including IOPS, bandwidth, read latency, write latency and total I/O latency. The administrator should correlate the VM's latency with its IOPS and throughput, then compare those values with storage-container, host and cluster-level metrics over the same interval. This determines whether the delay is isolated to the VM or reflects a broader storage condition.
License expiration may affect access to licensed features, but it is not the primary diagnostic explanation for an actively running VM's I/O responsiveness. RBAC controls administrative permissions rather than guest workload performance. Container sizing is not a standard immediate troubleshooting metric; the measurable symptom to examine first is latency.

NEW QUESTION # 58
Which security option should be implemented to ensure that all intra-cluster communication is secured?
Answer: D
Explanation:
Network Encryption is the security control directed at protecting data while it traverses the network between Nutanix cluster components. It provides cryptographic confidentiality and integrity for supported intra-cluster traffic, preventing captured traffic from being interpreted or modified without detection. In AOS 7.5, the documented intra-cluster data-in-transit encryption capability specifically covers Stargate storage traffic.
Accordingly, the examination wording should be interpreted as asking which option cryptographically secures intra-cluster communications, for which Network Encryption is the only valid choice.
Network Segmentation serves a different purpose. It isolates traffic categories-such as management, backplane, or replication traffic-onto separate networks. Segmentation can reduce exposure and limit broadcast or failure domains, but isolated traffic is not necessarily encrypted. Cluster Lockdown restricts administrative access, particularly access paths involving hosts and Controller VMs; it does not encrypt packets moving between cluster services. "vSwitch Lockdown" is not the relevant Nutanix data-in-transit security mechanism.
The decisive distinction is therefore encryption versus isolation or access restriction. If the requirement is that intercepted traffic must remain unreadable, an encryption capability is required. Segmentation may complement that control, but cannot replace it.

NEW QUESTION # 59
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 # 60
What is the purpose of Traffic Mirroring on AHV hosts?
Answer: C
Explanation:
Traffic Mirroring replicates selected network traffic from AHV interfaces or source ports and delivers the copied traffic to a designated virtual NIC on a guest VM. The destination VM normally runs monitoring, packet-capture, intrusion-detection, or network-analysis software. This permits inspection of traffic without placing the monitoring system directly within the source workload's forwarding path.
The destination receives copies of packets; it does not become the router or default gateway for the source traffic. Production traffic continues through its normal forwarding path, while the mirrored copy is supplied to the monitoring vNIC. Administrators must select the correct source interfaces, destination VM, direction, and placement configuration so that the monitoring system receives the intended traffic.
LACP performs physical uplink aggregation and link negotiation, which is unrelated to packet replication.
DHCP-based IP assignment is an IP address-management function. Routing overlay traffic through a VPC gateway belongs to Flow Virtual Networking and virtual private cloud routing, not AHV traffic mirroring.
The language in option B corresponds directly to the official function: traffic is mirrored from AHV host interfaces to a guest VM's vNIC. This is conceptually comparable to a switch-port analyzer capability implemented within AHV networking.

NEW QUESTION # 61
An administrator is working with Nutanix Support and has been asked to submit the NCC logs for further review.
How should the administrator gather the logs for the support case?
Answer: D
Explanation:
The supported Prism Element workflow for gathering diagnostic data is the Collect Logs feature. From the Health dashboard, the administrator opens the Actions menu, selects Collect Logs, identifies the relevant nodes and components, specifies the required time range or collection parameters, and starts the log-collection task. The resulting archive can then be associated with or uploaded for the Nutanix Support case.
Pulse is a proactive support and telemetry capability that periodically provides diagnostic system information to Nutanix. It does not automatically transmit every detailed NCC or component log required for a specific investigation. Nutanix documentation notes that when Pulse data is insufficient for diagnosis, Support may request a separate diagnostic log collection.
"Export Logs" and "Download Logs in Prism Central" are not the documented names of the NCC collection workflow described in the question. The explicit Health dashboard operation is Collect Logs. This process also allows the administrator to control which nodes and components are included, preventing irrelevant data from unnecessarily enlarging the support bundle.
