You have an Exchange Server 2010 organization. You have a global security group named Legal that
contains all the members of your company’s legal department. The company’s security policy states
that the Legal group must be able to search all mailboxes for e-mail messages that contain specific
keywords. You need to recommend a solution for the organization that complies with the security
policy. What should you include in the solution?

A.
a Discovery Management role group

B.
a legal hold

C.
administrator audit logging

D.
Mailbox journaling

Explanation:
In order to search mailboxes you need to be a member of the Discovery Management role group.
The Discovery Management role group is one of several built-in role groups that make up the Role
Based Access Control (RBAC) permissions model in Microsoft Exchange Server 2010. Role groups are
assigned one or more management roles that contain the permissions required to perform a given
set of tasks. The members of a role group are granted access to the management roles assigned to
the role group. For more information about role groups, see Understanding Management Role
Groups. Administrators or users who are members of the Discovery Management role group can
perform searches of mailboxes in the Exchange organization for data that meets specific criteria and
can also configure legal holds on mailboxes.
