Question 11

Report Export Collapse

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.)

Upgrade the vSAN On-Disk Format (ODF) to version 12.

Question 12

Report Export Collapse

An administrator has an absent capacity disk.

Which action, if any, should the administrator take to resolve the problem?

Wait, and vSAN will rebuild it.
Wait, and vSAN will rebuild it.
Replace the faulty disk.
Replace the faulty disk.
Replace the faulty host.
Replace the faulty host.
Verify the host is not isolated.
Verify the host is not isolated.
Suggested answer: B
Explanation:

The best action to take to resolve the problem is to replace the faulty disk, as stated in the VMware official guide: 'Hosts can include a maximum of five disk groups [1], each of which must have one flash cache device and one or more capacity devices [1]. In vSAN, each host can have a maximum of seven capacity devices, excluding the flash cache device [1]. The flash cache device is used to accelerate read and write operations [1], while the capacity devices provide the raw storage capacity for the vSAN cluster.'
