Which of the following statements is correct when deploying Cisco TelePresence in a centralized
call-processing scenario?
A.
Use Cisco unified SRST to provide for local survivability for the Cisco TelePresence endpoints
in the event of a WAN outage and use AAR to provide an alternative path for Cisco TelePresence
calls in the event that there is insufficient bandwidth on the WAN.
B.
Cisco TelePresence endpoints do not support SRST. The best solution is to build a redundant
WAN.
C.
AAR should be used to reroute Cisco TelePresence calls over a Cisco TelePresence
intercompany service provider in the event that the primary enterprise WAN path is unavailable.
D.
Every site in a centralized call-processing deployment must contain a Cisco Unified
Communications Manager node for the Cisco TelePresence endpoints to register to.
