NEW QUESTION 53
Your customer is using Replication Manager to make local TimeFinder/Clone backups of their Microsoft Exchange 2010 environment. The customer reconfigured the Exchange environment to place the logs on the L:\ drive and mount the database on L:\SG1DB1.

What do you advise the customer?

A.    Nested mount points are not supported with Replication Manager.
B.    A separate application set must be configured for the database.
C.    Additional clone targets need to be added to the storage pool.
D.    The database replica must be part of the same replica job as the logs.

Answer: A

NEW QUESTION 54
A customer recently reconfigured their Microsoft Exchange 2010 environment. They placed the log and system files on the L:\ drive and mounted the mailbox stores on L:\SG1DBMP.
