You need to group a set of cmdlets for administrative delegation.

What should you create?

A.
A managed folder mailbox policy.

B.
A new distribution group.

C.
A new management role.

D.
A new role assignment policy.

Explanation:
A management role assignment is the link between a management role and a role assignment policy. Assigning a management role to a role assignment policy grants the ability to use the cmdlets and parameters defined in the management role. When you create a role assignment between a role assignment policy and a management role, you can’t specify any scope. The scope applied by the assignment is based on the management role and is either Self or MyGAL.
