NSE 7 – SD-WAN 6.4 — Question 46

Which statement reflects how BGP tags work with SD-WAN rules?

Answer options

• A. VPN topologies are formed using only BGP dynamic routing with SD-WAN.
• B. Route tags are used for a BGP community and the SD-WAN rules are assigned the same tag.
• C. BGP tags require that the adding of static routes be enabled on all ADVPN interfaces.
• D. BGP tags match the SD-WAN rule based on the order that these rules were installed.

Correct answer: B

Explanation

The correct answer is B because BGP route tags are assigned to a community, and SD-WAN rules can utilize the same tags for routing decisions. Option A is incorrect as VPN topologies can use a combination of BGP and other routing methods. Option C is wrong because BGP tags do not require static routes to be enabled on ADVPN interfaces. Option D is also incorrect as BGP tags do not match SD-WAN rules based on installation order.
