VMware 5V0-21.21 Exam - Topic 3 Question 70 Discussion

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

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.)

I think deploying a new witness appliance might be overkill.

I feel like we should definitely deploy a new witness appliance, but I'm not entirely clear on whether we can use the existing one as shared.

I practiced a similar question where we had to update the cluster to use a new witness appliance. I wonder if that's relevant here too.

I remember that we need to upgrade the On-Disk Format, but I'm not sure if it should be version 12 or 13.

Deploying a new vSAN 7.0 U1 witness host appliance seems like an unnecessary step if we can just reuse the existing one. I'll focus on the more efficient options.

Upgrading the vSAN On-Disk Format (ODF) to version 12 should be the first step to ensure the new version of vSAN is compatible with the existing clusters.

Okay, I think I've got it. The key is to configure the existing witness host appliance to act as a shared witness after upgrading it to vSphere 7.0 U1.

Hmm, I'm a bit confused about the shared witness feature and how that fits into the upgrade process. I'll need to review that part more carefully.

I'd say D and E are the way to go. Leverage the existing witness host and also deploy a new one for redundancy. Can't be too careful with this kind of upgrade, you know.
