Question 8

What is the correct sequence of steps to present a volume to an ESXi host?

Question # 8

Options:

Question 9

After the implementation of a DR site with Synchronous replication all applications were up and running fine. The restore points were saved and validated; DR was predefined and successfully tested. Sometime later, one of the applications became unresponsive and initial troubleshooting points to Storage/Volume as the root cause.

Concerning the Replication to the DR site, what could be happening?

Options:

A.

Customer must switch to asynchronous replication as volumes tied to applications should not be synchronous replicated.

B.

The synchronous replication has been set to High Consistency and the link between the two sites is down.

C.

Unresponsive applications cannot be related to any DR or Replication practices

D.

Only asynchronous replication can possibly have a negative impact to volumes and applications if the link is down
