Tier 2 ISP A on AS 653 is connected to two Tier 1 ISPs on AS 321 and AS 51 respectively. The network architect at ISP A is planning traffic flow inside the network to provide predictable network services. Cisco Express Forwarding is disabled on the edge router. How should the architect implement BGP to direct all traffic via the Tier 1 ISP with next-hop 7.4.5.2?

1. A. Implement the BGP routing protocol and run the bgp deterministic-med command.
2. B. Implement MP-BGP with a 4-byte AS number with the bgp best path compare-routerid command.
3. C. Implement the BGP routing protocol and the maximum-paths 2 configuration.
4. D. Implement BGP route-reflector functionality with the bgp always-compare-med configuration.
