You are the Nutex Corporation’s Exchange 2010 administrator. The Chief Information Officer (CIO) is
apprehensive about applying upgrades and service packs until they are needed. What would be
reasons to apply SP1 to the Exchange 2010 servers in the organization?

A.
To preserve mailbox items that may have been deleted or edited by users

B.
To use annotations to associate a case number or another unique identifier with a message

C.
To get an estimate of search results to determine the total number and size of items returned by a
discovery search

D.
To enable search results of multiple mailbox servers to copy only one instance of a unique
message to the discovery mailbox on a mailbox server running Exchange 2010 or Exchange 2010 SP1

E.
To enable discovery searches of items placed on hold

Explanation:
The following are reasons to upgrade to Exchange 2010 SP1:
You can use annotations to associate a case number or another unique identifier with a message.
You can get an estimate of search results to determine the total number and size of items returned
by a discovery search.
Discovery managers can perform a discovery search across the cloud or on-premise servers. With
Exchange 2010 SP1, a discovery manager could get an estimate of the size of the search results
before running the search, and add annotations to messages. Annotations allow a discovery
manager to add annotations to the message. For example, a discovery manager can associate a
unique identifier with a message such as a case number. The discovery manger could then search for
all items with that number.
Exchange 2010 SP1 does not enable search results of multiple mailbox servers to copy only one
instance of a unique message to the discovery mailbox on a mailbox server running Exchange 2010.
Exchange 2010 SP1 contains a feature called deduplication that only works on a discovery mailbox
located on an Exchange 2010 SP1 Mailbox server. Deduplication copies only one instance of a unique
message to a discovery mailbox, reducing the size of the discovery mailbox size.
Exchange 2010 already includes the litigation hold feature. Litigation hold preserves mailbox
contents for discovery requests until a lawsuit has been concluded. A litigation hold will do the
following:
• Keep user’s mailbox items in an unaltered state
• Keeps mailbox items that may have been edited or deleted
• Keeps mailbox items automatically deleted by MRM
