Which two multicast protocol statements are true?()
A. Sparse mode multicast uses a pull model to send multicast traffic to where it is requestedB. Dense mode multicast uses a push model to flood traffic throughout the network and then prunes the unwanted trafficC. Dense mode multicast requires explicit join messa ges from their membersD. Sparse mode uses reverse path forwarding (RPF) to prune off redundant flowsE. The primary use of sparse mode multicast is for test labs and router performance testing
考题
Which two of these are differences between traffic policing and traffic shaping？（）A、with traffic shaping，a router stores excess traffic in packet buffers until bandwidth is available againB、with policing you can tune the buffer usage for traffic exceeding the specified CIRC、with shaping you can tune the buffer usage for traffic exceeding the specified CIRD、shaping should only be applied for ingress traffic，policing only for egressE、policing uses a token bucket algorithm，shaping uses an SPD algorithm
