Your network contains a Lync Server 2010 server that has Privacy Mode enabled for all users. You need to plan the deployment of Response Groups. What should you include in the plan?

A.
a Voice Policy for each Response Group

B.
the Attendant Console for each user configured as an Agent

C.
a trusted application for each Response Group

D.
modifications to the Contacts list of each user configured as an Agent

Explanation:
When you assign users as response group agents, inform them that, if they have Privacy mode enabled, they need to search for "RGS Presence Watcher" contacts and add them to their Contacts list. Agents who have Privacy mode enabled but who do not have "RGS Presence Watcher" in their Contacts list cannot receive calls to the response group. Agents who do not have Privacy mode enabled are not affected. (http://technet.microsoft.com/en-us/library/gg398917.aspx)
