NSE 7 – SD-WAN 7.0 — Question 50

Which statement about using BGP for ADVPN is true?

Answer options

• A. IBGP is preferred over EBGP, because IBGP preserves next hop information.
• B. You must use BGP to route traffic for both overlay and underlay links.
• C. You must configure BGP communities.
• D. You must configure AS path prepending.

Correct answer: A

Explanation

The correct answer is A because IBGP indeed preserves the next hop information, which is crucial for routing in ADVPN. Options B, C, and D are not necessary requirements for BGP in ADVPN; BGP is not mandated for all traffic, communities are not always required, and AS path prepending is an optional optimization.
