A service provider has a multi-access segment with two routers, R1 and R2, both running IGMPv2. R1 has an IP address of 10.1.1.1 and R2 has 10.1.1.2. R1 is the designated querier. R1 experiences a failure and stops sending queries. How long will it take for R2 to become the querier?

After the query response interval expires, which is typically 10 seconds.

After the group membership interval expires, which is typically 260 seconds.

After the querier timeout expires, which is typically 255 seconds.

Immediately, because R2 has a higher IP address.

What is the role of the IGMP querier on a multi-access network?

To maintain the multicast routing table for the entire network

To send periodic membership queries to discover which multicast groups have local members

To assign multicast group addresses to hosts

To forward multicast traffic to all routers on the network

What is the primary role of IGMP in an IP multicast network?

To route multicast packets between different autonomous systems

To manage group membership between hosts and their directly connected multicast router

To build a loop-free topology for multicast distribution trees

To encapsulate multicast packets for transport over a unicast-only network
