You are a messaging professional. Your company uses a Microsoft Exchange Server 2007 messaging system.

Your company has four Mailbox servers named Server1, Server2, Server3, and Server4. The first three servers have two storage groups each. The database in each storage group occupies 230 GB of disk space.
Server4 does not host any user mailboxes. All client computers run Microsoft Office Outlook 2007.

Mailbox data is backed up to tape media. Restoring a single database to a Mailbox server with active users takes more than 30 minutes. Otherwise, restoring a single database takes less than 30 minutes.

The Service Level Agreement (SLA) of the company is changed and has the following new requirements:

In the event of a single database failure, users must be able to access all previous e-mail messages within 30 minutes.
All mailboxes must be restored within four hours.
The recovery process must not affect mailboxes in other databases.

You need to create a single database failure recovery plan to meet the SLA requirements.

What should you include in the plan?

A.
Dismount the other databases on the computer that hosts the failed database. Restore the database to that
computer.

B.
Create a dial-tone database on an unaffected Mailbox server. Use a recovery storage group to restore the
mail databases. Merge the recovered data into the dial-tone database.

C.
Restore the failed database to Server4. Run a cmdlet command to modify the mailbox configuration of the
affected user objects.

D.
Install a new Mailbox server in an alternate recovery forest. Restore the database to the new Mailbox server.
Move the data to the affected Mailbox server.
