4. D. Tunnel Mode in IPsec Phase I

Correct Answer: B

Which architecture does not require an explicit multicast signaling protocol, such as PIM or P2MP, to signal the multicast state hop-by-hop, but instead uses a link state protocol to advertise the multicast forwarding state?

1. A. Binary indexed explicit routing
2. B. Binary intermediate enhanced routing
3. C. Bit indexed explicit replication
4. D. Bi-directional implicit replication

Correct Answer: C

Refer to the exhibit.

OSPF is running as the IGP to provide reachability to all AS100 networks R3 and R4 are the current ABRs at the boundary of OSPF Area0 and Areal Now BGP must be deployed within AS 100 because it will be receiving Internet routes from its eBGP peers (the service provider) connected to R1 and R2 What is an optimal solution for this deployment to configure BGP relationships and redistribute BGP learned routes into OSPF?

1. A. R5 should be configured as a route reflector for R1, R2, R3 and R4. BGP routes must be redistributed at R1 and R2 into OSPF.
2. B. Configuration should be set up with R1 and R2, and R3 in one sub AS, with and R4 in another, and redistribution at R1 and R2.
3. C. A full mesh should be deployed between all the routers with mutual redistribution to take place at R1 and R2.
4. D. R1, R2, R3 and R4 must be set up with a neighbor relationship with R5 only must not be a routereflector.

Correct Answer: C
