Deploying Cisco Service Provider Advanced Routing Solutions (SPROUTE, legacy) — Question 2

Which two unique attributes are used for the loop prevention mechanism when route reflectors are deployed in a network? (Choose two.)

Answer options

• A. local preference
• B. originator-ID
• C. AS-path
• D. next-hop
• E. origin
• F. cluster-list

Correct answer: B, E

Explanation

The correct attributes for loop prevention with route reflectors are originator-ID and origin. The originator-ID helps identify the source of the route, preventing loops, while the origin attribute indicates the source AS. Other options like local preference, AS-path, next-hop, and cluster-list are important in BGP but do not specifically serve the loop prevention role in this context.
