You are the messaging engineer for your company. Your messaging system is running Exchange Server 2007.
You need to create a disaster recovery plan for mailboxes and mailbox content. Your plan should meet the following requirements:
Deleted mailboxes and mailbox content must be available on backup media after they have been removed from the Exchange server.
Users must be able to recover mailbox content that has been deleted within the last seven days.
Administrators must be able to recover a mailbox that has been deleted within the last seven days.
Which three elements should your disaster recovery plan include? (Each correct answer presents part of the solution. Choose 3.)
A.
For each mailbox database, configure the information store to permanently delete items only after the
database has been backed up.
B.
For each mailbox database, configure the maintenance schedule to run every seven days.
C.
For each mailbox database, set the deleted mailbox retention time to seven days.
D.
For each mailbox database, set the deleted item retention time to seven days.
E.
For each mailbox database, allow the database to be overwritten by a restore.

Get-Mailboxdatabase | Set-Mailboxdatabase -DeletedItemRetention 7.00:00:00 -MailboxRetention 7.00:00:00 -RetainDeletedItemsUntilBackup $true
Use Get-MailboxDatabase to retrieve one or more mailbox database objects from a storage group, server, or organization. Without parameters, returns all databases in the organization.

Use Set-MailboxDatabase to set database properties. Use DeletedItemRetention and MailboxRetention to specify length of time to keep deleted items and mailboxes. Enter values as a time span: dd.hh:mm:ss, where d = days, h = hours, m = minutes, and s = seconds. The maximum time is 24,855 days. (By default, deleted items and mailboxes are retained for 14 and 30 days, respectively.) These parameters apply, respectively, to all mailboxes in the database and to all mailboxes without their own item retention attribute set. RetainDeletedItemsUntilBackup determines whether to retain delete items until after the next backup; possible values: $true or $false.
