Which of the following is supported by MCUs deployed as media resources on Cisco Unified CM?

A.
TLS

B.
BFCP

C.
cascading

D.
ad hoc conferencing

E.
scheduled conferencing

Explanation:
Ad hoc conferencing is supported by multipoint control units (MCUs) deployed as media resources on Cisco
Unified Communications Manager (CM). Ad hoc conferences generally include auto attendant conferences,
rendezvous conferences, and Multiway conferences; however, only rendezvous conferences and Multiway
conferences are supported on Cisco Unified CM.
Scheduled conferencing is not supported by MCUs deployed as media resources on Cisco Unified CM.
Scheduled conferencing is available only with MCUs that register to Cisco TelePresence Video Communication
Server (VCS).
Cascading is not supported by MCUs deployed as media resources on Cisco Unified CM. Optimally, all
participants in a conference will be connected to a single MCU. However, when there are not enough ports on
an MCU for all of the participants, the MCU can cascade to another MCU in order to handle the load. Dynamic
cascading is supported by Cisco TelePresence Conductor; manual cascading is supported only by VCS.
Binary Floor Control Protocol (BFCP) is not supported by MCUs deployed as media resources on Cisco Unified
CM. BFCP is a content-sharing protocol that uses a separate content channel to enable endpoints to display
presentation materials and participants simultaneously.
Transport Layer Security (TLS) is not supported by MCUs deployed as media resources on Cisco Unified CM.
TLS is used to encrypt media and signaling for calls.
