Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) — Question 68

An engineer configured two routers connected to two different service providers using BGP with default attributes. One of the links is presenting high delay, which causes slowness in the network.
Which BGP attribute must the engineer configure to avoid using the high-delay ISP link if the second ISP link is up?

Answer options

• A. AS-PATH
• B. WEIGHT
• C. MED
• D. LOCAL_PREF

Correct answer: D

Explanation

The correct answer is LOCAL_PREF because it allows the engineer to indicate a preferred exit point from the AS, effectively directing traffic away from the high-delay link. Other attributes like AS-PATH or MED do not prioritize local routes, while WEIGHT is specific to a router and does not influence BGP decisions across multiple routers.
