Which two pieces of information does RTCP use to inform endpoint devices about the RTP flow?
(Choose two.)
A.
the transmitted octet
B.
the lost packet count
C.
session control function provisioning information
D.
the CNAME for session participants
E.
the authentication method
F.
MTU size changes in the path of the flow
RTCP transports statistics for a media connection and information such as transmitted octet and
packet counts, packet loss, packet delay variation, and round-trip delay time. An application may
use this information to control quality of service parameters, perhaps by limiting flow, or using a
different codec.
