Question 5 VMware 2V0-21.23
QUESTION DESCRIPTION:

An administrator plans to update the Supervisor cluster and has noticed some of the Tanzu Kubemetes Grid clusters are running an incompatible version.

Which action must the administrator take before proceeding with the Supervisor cluster update?

  • A.

    Update all Tanzu Kubernetes Grid clusters to the latest version prior to the Supervisor cluster update.

  • B.

    No action is needed - Tanzu Kubernetes Grid clusters will be updated automatically as part of the update process.

  • C.

    No action is needed - Incompatible Tanzu Kubernetes Grid clusters can be manually updated after the Supervisor cluster update.

  • D.

    Update incompatible Tanzu Kubernetes Grid clusters prior to the Supervisor cluster update.

Correct Answer & Rationale:

Answer: D

Explanation:

Option D is correct because it indicates that the administrator must update incompatible Tanzu Kubernetes Grid clusters prior to the Supervisor cluster update, as this will ensure that there are no compatibility issues or disruptions during or after the update process. Option A is incorrect because it is not necessary to update all Tanzu Kubernetes Grid clusters to the latest version prior to the Supervisor cluster update, as some clusters may already be compatible with the new version. Option B is incorrect because Tanzu Kubernetes Grid clusters will not be updated automatically as part of the update process, as they require manual intervention from the administrator. Option C is incorrect because incompatible Tanzu Kubernetes Grid clusters cannot be manually updated after the Supervisor cluster update, as they may become inaccessible or unstable due to compatibility issues. References: https://docs.vmware.com/en/VMware-vSphere/7.0/vmware-vsphere-with-tanzu/GUID-9F9E3F8C-0E2B-4B6A-8C5C-3F8E5F6B4E9D.html

    vSphere Virtual Volumes (vVols)

  • E.

    Network File System (NFS) 4.1

Correct Answer & Rationale:

Answer: B, D

Explanation:

Option B and D are correct because they are the datastore types that store the components of a virtual machine as a set of objects, which are logical containers that abstract physical storage resources. Option A, C and E are incorrect because they are the datastore types that store the components of a virtual machine as a set of files, which are stored on a file system that resides on a physical storage device. References: https://docs.vmware.com/en/VMware- vSphere/7.0/com.vmware.vsphere.storage.doc/GUID-9F9E3F8C-0E2B-4B6A-8C5C-3F8E5F6B4E9D.html

  • A.

    Delete App-LibTemplate (2)

  • B.

    Revert to App-LibTernplate (2)

  • C.

    Delete App-LibTemplate (3)

  • D.

    Check out App-LibTemplate (3)

Correct Answer & Rationale:

Answer: B

Explanation:

Deleting App-LibTemplate (3) will remove the changes that are no longer needed and revert to the previous version of the template.

References: https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.vm_admin.doc/GUID-9A5093A5-C54F-4502-941B-3F9C0F573A39.html

https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.vm_admin.doc/GUID-D69B0279-CC9B-495B-9CA3-AE975AF9C865.html

If the latest VM template contains changes that are no longer needed, the administrator should  revert  to the previous version of the template 1 .

Here are the steps to revert to a previous version of a template 1 :

    Navigate to the  Versioning tab  of the VM template.

    From the vertical timeline, navigate to the previous state of the VM template.

    Click the horizontal ellipsis icon ( ⋮ ), and select   Revert to This Version .

    The Revert to Version dialog box opens. Enter a reason for the revert operation and click  Revert .

So, in this case, the correct answer is: B.  Revert to App-LibTemplate (2)

This will make App-LibTemplate (2) the current VM template 1 .  Please note that this operation will not delete App-LibTemplate (3), it will simply make App-LibTemplate (2) the current version 1 .

Question 10 VMware 2V0-21.23
QUESTION DESCRIPTION:

An administrator Is performing maintenance activities and discovers that a Virtual Machine File System (VMFS) datastore has a lot more used capacity than expected. The datastore contains 10 virtual machines (VMs) and, when the administrator reviews the contents of the associated datastore, discovers that five- virtual machines have a snapshot file (-delta.vmdk flies) that has not been modified In over 12 months. The administrator chei kfl the Snapshot Manager within the vSphere Client and confirms that there are no snapshots visible.

Which task should the administrator complete on the virtual machines to free up datastore space?

  • A.

    Consolidate the snapshots for each VM.

  • B.

    Inflate the disk files for each VM.

  • C.

    Delete all snapshots for each VM.

  • D.

    Storage vMotion each VM to another datastore.

Correct Answer & Rationale:

Answer: A

Explanation:

Consolidating snapshots for each VM will merge any snapshot files that are not associated with a snapshot in Snapshot Manager into the base disk file and free up datastore space.

References: https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.vm_admin.doc/GUID-53F65726-A23B-4CF0-A7D5-48E584B88613.html

The presence of redundant delta disks can adversely affect the virtual machine performance. You can combine such disks without violating a data dependency. After consolidation, redundant disks are removed, which improves the virtual machine performance and saves storage space.
