When using the LCM Dark Site procedure in Prism Element or Prism Central, which Nutanix software
component should be checked and upgraded first?
A.MSP
B.NCC
C.LCM Framework
D.Foundation VM
Select the answer
1 correct answer
A.
The correct answer is C. LCM Framework.

For a Nutanix LCM Dark Site procedure in Prism Element or Prism Central, check the LCM Framework first and upgrade it if needed. The framework provides the lifecycle-management functions used to discover software and firmware versions, process dark-site update information, and coordinate upgrades. Using a compatible, up-to-date framework helps ensure the rest of the LCM workflow can run correctly.

The other options serve different purposes:

A. MSP is not the component that should be checked and upgraded first for this LCM procedure.
B.
NCC provides health checks and diagnostics; it is useful for validating cluster health but is not the LCM component identified for this step.
C.
Foundation VM is primarily used for Nutanix software installation and imaging, not for managing LCM upgrades.

So, the first component to check is the LCM Framework.

What are two requirements to upgrade Nutanix Guest Tools on a VM? (Choose two.)
A.VM Powered Off
B.DNS Entry for VM
C.VM Powered On
D.Empty CD Drive
Select the answer
2 correct answers
A.
The correct answers are C and D: VM Powered On and Empty CD Drive.

Nutanix Guest Tools (NGT) is upgraded from within the guest operating system. The VM must be powered on so the upgrade process can run and the guest OS can install the updated tools. NGT also uses the VM’s virtual CD drive to mount the installation media, so that drive must be present and empty.

A. VM Powered Off: Incorrect. The guest OS needs to be running for the upgrade process.
B.
DNS Entry for VM: Incorrect. A DNS entry is not a prerequisite for upgrading NGT.
C.
VM Powered On: Correct. The guest OS must be running to perform the upgrade.
D.
Empty CD Drive: Correct. The virtual CD drive is used for the upgrade media and must be available.

Quiz

A VM is experiencing delays even though its own CPU usage appears low.
Which metric should be checked to identify scheduling issues?
A.CPU Ready
B.Disk capacity
C.Memory usage
D.Snapshot size
Select the answer
1 correct answer
The correct answer is A. CPU Ready.

CPU Ready measures how long a virtual machine is ready to run but is waiting for the hypervisor to schedule it on a physical CPU. A VM can therefore experience delays even when its reported CPU usage is low: it may not be getting enough time on the host’s CPUs to do work.

A high CPU Ready value can indicate host CPU contention or overcommitment. Disk capacity, memory usage, and snapshot size may affect performance in other ways, but they do not directly identify CPU scheduling delays.

Quiz

How can an administrator protect volume-based containerized workloads?
A.Configure a replication policy
B.Enable Disaster Recovery in Prism Central
C.Use Nutanix Data Services for Kubernetes
D.Set up Objects replications
Select the answer
1 correct answer
A.
The correct answer is C. Use Nutanix Data Services for Kubernetes.

Nutanix Data Services for Kubernetes (NDK) provides data protection capabilities for Kubernetes applications that use persistent, volume-based storage. It integrates with Kubernetes and Nutanix storage to manage persistent volumes, including creating snapshots and supporting replication and recovery. This lets an administrator protect the data used by containerized workloads.

Why the other options are less suitable:

A. Configure a replication policy. A replication policy can be part of a storage-protection setup, but this option does not identify the Kubernetes-aware service used to protect containerized workloads and their persistent volumes.
B.
Enable Disaster Recovery in Prism Central. Prism Central disaster recovery is generally aimed at protecting virtual machines and their associated data. It is not the specific Kubernetes-focused option for protecting persistent volumes used by containers.
C.
Set up Objects replications. Nutanix Objects replication protects object-storage data, such as data in buckets. It does not protect Kubernetes persistent volumes, which are typically block-volume storage.

Therefore, NDK is the best choice because it provides protection designed for Kubernetes workloads and their persistent volumes.

Which component is required to prevent split-brain scenarios on a 2-node ROBO cluster?
A.Prism Central
B.Prism Element
C.Foundation Central
D.Witness VM
Select the answer
1 correct answer
The correct answer is D. Witness VM.

A 2-node ROBO cluster has no third cluster node to break a tie if the two nodes lose communication with each other. Without a tie-breaker, each node could believe the other has failed and attempt to keep running the cluster independently, creating a split-brain scenario.

The Witness VM acts as an independent quorum vote. It helps determine which node or partition should remain active when the nodes cannot communicate, reducing the risk that both sides operate as separate clusters. It should be placed in a separate failure domain when possible.

Prism Central and Prism Element provide management interfaces, and Foundation Central supports deployment and imaging. They do not provide the quorum function needed to prevent split brain.

A VM is experiencing poor performance at the storage level.
After reviewing the image, which action should the administrator take?
A.Verify if a Storage Policy is impacting the VM.
B.Migrate VM to another host.
C.Increase CVM memory size.
D.Add additional SSD disks to all the nodes in the cluster.
Select the answer
1 correct answer
A.
The correct answer is A. Verify whether a Storage Policy is impacting the VM.

A Storage Policy can affect how a VM’s data is handled and may impose settings or limits that influence storage performance. The administrator should review the policy assigned to the VM and check for relevant constraints, such as I/O limits or storage-placement settings, before making infrastructure changes.

Why the other options are less appropriate:
B.
Migrate the VM to another host. This may help with a host-specific compute issue, but the problem is identified as storage-level performance. Moving the VM does not necessarily change its storage policy or resolve a storage bottleneck.
C.
Increase CVM memory size. Increasing Controller VM memory is a broader cluster-level change and is not justified without evidence that CVM memory is the cause.
D.
Add additional SSD disks to all nodes in the cluster. This is a significant capacity and cost change. It should only be considered if metrics confirm that SSD capacity or storage throughput is the bottleneck, not as the first troubleshooting step.

The sensible first action is to inspect the VM’s assigned Storage Policy and determine whether its settings are contributing to the performance issue.
