Question 555

How does an IGMP router maintain group memberships on the network? (Choose two.)

The router maintains a timer for each group membership. If the router receives a Report message from a receiver host, it refreshes the timer of the group membership of this host; if the router does not receive any Report message from areceiver host before the timer expires, it deletes the group membership of this host.

The router periodically sends Query messages. After a receiver host receives the Query message, the receiver host sends a Report message.

A receiver host periodically sends a Report message.

The router deletes a group membership only when it receives a Leave message for this group.
