考题
Which two statements are true about Internet Group Management Protocol (IGMP) snooping?()
A. IGMP snooping and Cisco Group Membership Protocol (CGMP) can be used simultaneously on a switch.B. IGMP snooping a nd Cisco Group Membership Protocol (CGMP) were developed to help Layer 3 switches make intelligent forwarding decisions on their own.C. IGMP snooping examines IGMP join/leave messages so that multicast traffic is forwarded only to hosts that sent an IG MP message toward the router.D. IGMP snooping is an IP multicast constraining mechanism for Layer 2 switches.E. IGMP snooping is enabled with the ip multicast - routing global configuration command.
