Assuming that all BGP neighbor relationships have been formed and that the attributes have not been changed on any of the routers, which configuration accomplish task?
A . R4(config-router)bgp default local-preference 200
B . R3(config-router)neighbor 10.1.1.1 weight 200
C . R3(config-router)bgp default local-preference 200
D . R4(config-router)nighbor 10.2.2.2 weight 200

Answer: C

Explanation:

To ensure that all traffic leaving AS 200 chooses Link 2 as the exit point, the local preference attribute can be used. By setting a higher local preference on R3 for routes learned via Link 2, traffic will prefer this path over others. The command bgp default local-preference 200 on R3 will accomplish this task, as local preference is a well-known discretionary BGP attribute that influences the outbound traffic policy by indicating the preferred path to exit the AS.
