Question 3

Due to an update in their security requirements, an organization is no longer compliant because the metadata traffic between hosts in their vSAN cluster is not being encrypted.

Which step must be taken by the administrator to meet the new security requirements?

Options:

A.

Enable vMotion encryption on the vSAN cluster.

B.

Enable virtual machine encryption on the vSAN cluster.

Question 4

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.

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.

Question 7

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.

• 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.
