Question :-

Which of the following statements is correct when deploying Cisco TelePresence in a centralized call-processing scenario?
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
Cisco TelePresence endpoints do not support SRST. The best solution is to build a redundant WAN.
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.
Every site in a centralized call-processing deployment must contain a Cisco Unified Communications Manager node for the Cisco TelePresence endpoints to register to.
