Huawei Certified ICT Expert – Routing and Switching (HCIE-RS) — Question 1

Which of the following BGP route attributes cannot be used to control BGP route selection?

Answer options

• A. Community
• B. AS_Path
• C. MED
• D. Originator ID

Correct answer: A

Explanation

The correct answer is A, as the Community attribute is used for tagging routes rather than directly influencing the BGP route selection process. In contrast, AS_Path, MED, and Originator ID are all attributes that can have a direct impact on how BGP selects the best route.
