Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) — Question 317

Which BGP attribute can be used to influence the path that incoming traffic takes into your AS from other Autonomous Systems?

Answer options

• A. Metric manipulation
• B. AS_Path
• C. Weight
• D. Local Preference

Correct answer: B

Explanation

The correct answer is B, AS_Path, because it is used to determine the best route by listing the Autonomous Systems that a route has traversed. The other options, while related to BGP, do not directly influence the incoming traffic path in the same way; for example, Weight is a Cisco-specific attribute and Local Preference is used for outbound traffic preferences.
