You need to recommend a PSTN connectivity solution for the branch office that meets the companys availability requirements. What should you include in the recommendation?
A.
Location Policies
B.
Exchange Server 2010 Unified Messaging (UM)
C.
Call Admission Control
D.
multiple voice route policies
Explanation:
[!] Need full case info, but there ain’t such a thing as "voice route policy" – only Voice Routes and Voice Policies. One Voice Policy can have several Voice Routes linked to it. Location Policies and UM do not relate to PSTN connectivity at all. So the only viable option is CAC, as it allows call rerouting depending on bandwidth availability.
Availability Requirement is Minimize the bandwidth utilization of the WAN links. So correct answer is C.
Call Admission Control (CAC)
CAC is a way to manage whether new calls for voice or video should be established depending on available network bandwidth. If a new voice call exceeds the bandwidth limit you have set for the destination on a WAN, the call is either blocked or rerouted.
There is no such thing as a Voice route policy!! So yes C is correct
