Which action should the administrator take on the vmkernel portgroup on all hosts used by Virtual SAN cluster to resolve this problem?
A. Select the Virtual SAN traffic option
B. Increase the MTU value
C. Change the DNS server address
D. Increase the Port Speed
Correct Answer: A
Explanation/Reference:
Explanation:
To be able to use Virtual SAN, you must correctly configure network interfaces on the ESXi host that are included in the Virtual SAN cluster. The hosts use the Virtual SAN network to communicate with each other. In this question, the VMkernel network adapters on the hosts have not been configured to use the Virtual SAN network.
On each host that participates in the Virtual SAN cluster, create a VMkernel network adapter to use as a Virtual SAN interface.
Procedure
In the vSphere Web Client, navigate to the host.
Click the Manage tab and click Networking.
Select VMkernel adapters and click the Add host networking icon.
On the Select connection type page, select VMkernel Network Adapter and click Next.
Configure a target device.
On the Port properties page, select Virtual SAN traffic.
Complete the VMkernel adapter configuration.
Verify that the Virtual SAN column shows Enabled as the status for the VMkernel adapter.
Incorrect Answers:
B: This is not an MTU size issue. Therefore, this answer is incorrect.
C: This is not a DNS Server address issue. Therefore, this answer is incorrect.
D: This is not a port speed issue. Therefore, this answer is incorrect.
