JNCIS-ENT: Juniper Networks Certified Specialist – Enterprise Routing and Switching (2024) — Question 69

Which two statements describe BGP attributes? (Choose two.)

Answer options

• A. BGP attributes help determine the best path to a destination.
• B. The origin attribute indicates the autonomous systems through which the route has traversed.
• C. BGP attributes are always optional.
• D. The AS path attribute indicates the autonomous systems through which the route has traversed.

Correct answer: A, D

Explanation

Option A is correct because BGP attributes are used to evaluate and select the best path to a destination. Option D is also correct as it specifies that the AS path attribute reflects the autonomous systems that the route has passed through. Options B and C are incorrect; the origin attribute does not indicate the autonomous systems, and BGP attributes can be mandatory or optional depending on the context.
