Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) — Question 37

Which BGP attribute is used first when determining the best path?

Answer options

• A. origin
• B. AS path
• C. local preference
• D. weight

Correct answer: D

Explanation

The weight attribute is the first one evaluated by BGP when determining the best path, as it is a local attribute that influences path selection at the router level. Other attributes like origin, AS path, and local preference are considered later in the decision-making process, making them less influential in this initial evaluation.
