Question 6

An organization has two vSAN clusters managed by the same vCenter server, each providing 100 TB
of storage. The first cluster runs at 75% of its storage capacity, and the second cluster runs at 40% of
its storage capacity.
The company also has the following:
• an iSCSI array of 300 TB, which runs at 76% of its capacity
• a NAS system of 200 TB, which runs at 10% of its capacity
• a Fiber channel (FC) array of 300 TB, which runs at 80% of its capacity
The administrator is asked to add an additional 25 TB of storage to the first cluster but is also made
aware that there is no budget to purchase new hardware and that the vSAN Storage Policy Based
Management must be kept in place.
Which storage option will work for this use case?

  • A. Use the iSCSI array to obtain additional free capacity.
  • B. Use the NAS to obtain additional free capacity.
  • C. Use an HCI Mesh to obtain additional capacity.
  • D. Use the FC array to obtain additional free capacity.

Question 10

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.)

  • 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.
