H3C Constructing H3C High-Performance Campus Networks Sample Questions:
1. The following statements about multicast routing protocols are correct:
A) Intra-domain multicast routing protocols include: MSDP, DVMRP, MOSPF, PIM
B) In sparse mode, the multicast data stream is sent from the multicast source to the multicast receiver in a pull mode, and the multicast receiver actively sends and receives requests
C) The multicast routing protocol has two modes: dense and sparse
D) In dense mode, the multicast data stream is flooded from the multicast source to every corner of the network by pushing, and the multicast receiver passively receives multicast packets
