Captain Marion’s Videography delivers Internet digital video using 9 MPEG video encoders and astatistical multiplexer. Channels are packed into a 6-MHz channel bandwidth.The MPEGmultiplexe monitors and allocates the appropriate bandwidth. The multiplexer measures available bandwidth and feeds back signaling to the MPEG encoders. Coding rates are then increased ordecreased. Packet generation from each input source is controlled such that no packets aredropped and no extra null packets can be generated. These bandwidth and traffic requirements work best with which mode of video delivery？（）

A. It resembles a Layer 2 bridge.
B. Traffic flow through the IPS resembles traffic flow through a Layer 3 router.
C. Inline interfaces which have no IP addresses cannot be detected.
D. Malicious packets that have been detected are allowed to pass through， but all subsequent traffic is blocked.

A. Use CBWFQ to queue the peer-to-peer traffic into the default traffic class.
B. Use class-based WRED to randomly drop the peer-to-peer traffic during network congestions. 
C. Use class-based policing to limit the peer-to-peer traffic rate.
D. Use class-based shaping to delay any excessive peer-to-peer traffic.

A. source port
B. output interface
C. next-hop IP address
D. source MAC address
E. destination IP address
F. next-hop MAC address
