An administrator has identified and resolved a critical alert on the health dashboard. What should the administrator do to confirm the alert/issue has been resolved?
Correct Answer: C
The administrator should rerun the relevant Nutanix Cluster Check after completing the corrective action. NCC evaluates cluster configuration, services, hardware and operational conditions against Nutanix-defined health criteria. A new PASS or appropriate INFO result provides technical confirmation that the underlying condition no longer exists. Refreshing the Prism Element dashboard only reloads the displayed information. It does not independently retest the component or service that generated the alert. Deleting an email notification has no effect on the alert or cluster state. Manually marking an alert as resolved changes its administrative status but does not prove that the underlying fault has been corrected. Doing so without validation could conceal an active problem. If the rerun produces WARN, FAIL or ERR rather than PASS or INFO, the administrator must review the new output and continue remediation. For a narrowly scoped issue, the relevant NCC check can be selected; a broader health review may justify running the complete NCC suite.

Question 2
What is the purpose of Traffic Mirroring on AHV hosts?
Correct Answer: B
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.

Question 3
Which tool tests how a Nutanix environment will behave under a simulated production load?
Correct Answer: D
Nutanix X-Ray is an automated testing and benchmarking framework that runs repeatable scenarios against hyperconverged infrastructure targets. It uses realistic workload generators and controlled infrastructure events to evaluate performance, resilience, scalability, data integrity, and availability. Its scenarios can simulate conditions such as VM cloning, snapshots, migrations, node failures, node power-offs, and sustained storage workloads. X-Ray is intended for evaluation and test environments rather than active production clusters. The resulting metrics and reports allow architects and administrators to compare configurations and determine how an environment behaves under representative production-style demand and failure conditions. Nutanix Move migrates workloads between supported platforms and does not benchmark infrastructure behavior. Nutanix Collector gathers environmental information for assessment and sizing activities but does not generate simulated application loads. Nutanix Foundation images nodes and deploys or configures clusters; it is not a performance-testing framework. The requirement to test behavior under simulated load therefore maps directly to X-Ray's scenario-based testing model. References: Nutanix X-Ray FAQ and X-Ray 4.4 - Test Scenarios .

Question 4
A virtual machine needs to be placed on a different storage location within the cluster. Which task should be performed?
Correct Answer: A
Moving a VM's existing storage to a different storage container requires a vDisk placement change, implemented through live vDisk migration across storage containers. Nutanix supports migrating the attached vDisks of a running VM to a target container without deleting or shutting down the VM, subject to the documented requirements and limitations. The administrator can move an individual vDisk or all supported vDisks belonging to the VM. A category assigns metadata used for organization, governance, automation, and policy association; it does not directly relocate existing disk data. Image placement policies determine which clusters receive images from the image service, not where an existing VM's attached vDisks are stored. A storage policy controls storage characteristics such as QoS or other supported data-service properties. It is not the general storage- container migration task. The keyed answer D is particularly problematic because Nutanix documents that a vDisk cannot be migrated to another container while a storage policy is configured for the associated VM. Applying such a policy can therefore prevent the requested migration rather than accomplish it. References: Migrating a vDisk to Another Container and Storage Policy Management . NHCF alignment: storage operations and vDisk management.
Question 5
On a one-node cluster, which updates are supported with LCM?
Correct Answer: A
Life Cycle Manager supports software updates on a single-node cluster but does not support firmware updates in that configuration. Firmware maintenance commonly requires hardware components, host services, or the node itself to be restarted. A conventional multi-node cluster can move workloads and maintain storage availability through other nodes while one node undergoes maintenance. A one-node cluster has no alternate node to preserve cluster services during that process. "Software only" is broader and more accurate than "AOS only." LCM can manage supported Nutanix software components according to the applicable compatibility and upgrade paths; support is not restricted exclusively to AOS. Inventory is also available as an LCM operation, but option B incorrectly implies that inventory is the only supported capability. The platform restriction is therefore based on update type: software lifecycle operations are supported, while automated firmware updates are excluded because of the unavoidable service interruption and absence of node-level redundancy. Administrators must still confirm component interoperability and supported upgrade paths before initiating any update. Nutanix explicitly states that LCM is supported for software updates on single-node clusters but not for firmware updates. Reference: Prism 7.5 - Single-Node Cluster Requirements and Limitations .
