VMware App Volumes Specialist (2021) — Question 58

An administrator would like to upgrade ten identically configured 2-node vSAN clusters from vSAN 6.7 U3 to vSAN 7.0 U1. Currently, each 2-node vSAN cluster is using a dedicated vSAN witness host appliance. As a result of the upgrade, the administrator would like to leverage the vSAN shared witness feature to reduce the resources being consumed.

In preparation for the first vSAN cluster upgrade, the administrator has completed the following tasks:

1. Upgraded vCenter Server to vCenter Server 7.0 U1.
2. vSphere High Availability (HA) has been disabled on the vSAN Cluster.
3. Upgraded the vSAN witness host appliance to vSphere 7.0 U1.
4. Upgraded both vSAN data nodes to vSphere 7.0 U1.

The key requirement is to ensure that backwards compatibility to the existing version of vSAN is maintained during the upgrade process.

Which three additional steps should the administrator complete to ensure that subsequent clusters can share the same vSAN Witness? (Choose three.)

Answer options

• A. Upgrade the vSAN On-Disk Format (ODF) to version 12.
• B. Manually update the vSAN Witness with a vSAN 7 license key.
• C. Update the vSAN cluster to use the new vSAN witness host appliance.
• D. Configure the existing witness host appliance to act as a shared witness.
• E. Deploy a new vSAN 7.0 U1 witness host appliance to act as a shared witness.
• F. Upgrade the vSAN On-Disk Format (ODF) to version 13.

Correct answer: C, D, F

Explanation

The correct steps are C, D, and F. By updating the vSAN cluster to use the new witness host appliance (C), configuring the existing witness to act as a shared witness (D), and upgrading the On-Disk Format to version 13 (F), the administrator ensures compatibility and resource efficiency. Options A, B, and E are not necessary for enabling shared witness functionality in this scenario.
