You are the messaging engineer for your company. You are evaluating the storage requirements for Exchange Server 2007.

You need to recommend a storage solution that meets the following requirements:

Use Local Continuous Replication for all mailbox databases.

Back up mailboxes for users of the finance department twice a day.

Back up mailboxes for all other users once a day.

Only use Microsoft Windows Backup for backups.

What storage solution should you recommend?

A.
One storage group that contains one mailbox database.

B.
One storage group that contains two mailbox databases. One mailbox database is for users of the finance
department. The other mailbox database is for all other users.

C.
Two storage groups that both contain two mailbox databases.

D.
Two storage groups that both contain one mailbox database.

Explanation:
Since require different backup schedules for each group of users, must configure two separate storage groups.

EMC > Server Configuration > Mailbox > Database Management > Storage Group > Enable LCR Wizard…

Implementing LCR involves preparing a storage group and database topology. LCR cant be used on a clustered Mailbox server or for a recovery database. When a storage group is configured for LCR, it can only contain a single database. The storage group and database must already exist, mounted or dismounted.
