LAST WEEK'S ANSWER:
Answer: b
Topic Domain: 2b
Issues:
Which of these statements regarding IGMP snooping are correct?
Solutions:
By default, IGMP snooping examines PIM/DVMRP packets on all VLANs. When
you change this behavior and indicate you want IGMP snooped, the router
listens to only CGMP self-join and CGMP proxy-join packets and to no
other CGMP packets. You always have the option of statically configuring
ports on the switch.

LAST WEEK'S QUESTION:
2-11-1. You are considering the implementation of IGMP Snooping in your
Campus LAN in order to help reduce network congestion. You want to
ensure that multicast-capable router ports are added to the forwarding
table for every Layer 2 multicast entry using the snooping of CGMP
packets. Which statement below is true?
a. By default, the switch snoops on CGMP packets only on all
VLANs
b. This can be configured with the command ip igmp snooping vlan
vlan_id mrouter learn cgmp
c. The switch will snoop all CGMP packets once the feature is
enabled
d. Snooping of CGMP packets will render static assignment of
ports impossible
