Answers:
1. "A, "B". BGP peer relationships use TCP port 179 to keep peer relationships alive, and its use of TCP is why we consider them to be reliable and connection-oriented.
2. "C". Full updates are sent only after the BGP peering is formed. Updates will then be sent when there's a change in the network, but that update will reflect only the change - it will not be a full network update.
3. "C". Route reflectors are one way around split horizon.
4. "B". When a route reflector receives routes from a nonclient peer, that route is reflect to the RR's clients only.
5. "E". BGP does not have a dynamic neighbor discovery protocol.
6. The only optional BGP non-transitive attribute is the MED.
7. "C". "Multihoming" is the process of using BGP to connect an AS to more than one ISP.
