Which tech nology manages multicast traffic at Layer 2 by configuring Layer 2 LAN interfaces dynamically to forward multicast traffic only to those interfaces that want to receive it?()
A. IGMPB. IGMP snoopingC. PIM - DMD. DVMRPE. MOS PF
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.

Which three statements are true about the Internet Group Management Protocol (IGMP)? ()
A. There are three IGMP modes: dense mode, sparse mode, and sparse - dense modeB. IGMP is used to register individual hosts with a multicast groupC. IGMP version 3 enables a multicast receiving host to specify to the router which sources it should forward traffic fromD. IGMP messages a re IP datagrams with a protocol value of 2, destination address of 224.0.0.2, and a TTL value of 1E.
