Question 50/205

Resource Reservation Control (RRC) provides enhanced capabilities to manage admission and policy controls when deploying VideoStream on a Cisco Unified Wireless Network. Which statement correctly states the decision making process RRC goes through to admit or deny a client from joining a stream?

A. RRC initiates admission and policy decisions based on the radio resource measurements, traffic statistics measurement, and system configurations. The WLC initiates RRC requests to the APs for the IGMP join.

B. The WLC processes IGMP join requests after checking all the parameters, including client count, channel utilization, latency, QoS, and client link rates.

C. RRC algorithm periodically checks if conditions have changed. If a policy is violated, the client will be denied to the stream immediately. When the condition improves, the client will be admitted to join again.

D. RRC is a control mechanism to ensure good connection quality for a video stream via multicast. Clients that do not satisfy all conditions will always be admitted as best effort clients. Clients that do not get admitted 3 times within a specific time period, are denied access to the stream.

E. RRC algorithm will check and ensure the conditions are optimal before the client gets admitted. If the conditions are only partially satisfied, the client will be admitted but will have a better QoS priority to protect the stream quality.
