NSE 7 – SD-WAN 6.4 — Question 56

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

Answer options

• A. SD-WAN rules that use BGP tags have precedence over regular policy routes.
• B. Routes tags are mapped to the local preference attribute.
• C. Route tags can be used to specify the destination subnets in SD-WAN rules.
• D. If the destination network learned using BGP tag changes, you must re-configure the BGP tag so the information on the SD-WAN rule is updated.

Correct answer: C

Explanation

The correct answer is C because BGP tags are specifically used to identify and direct traffic towards certain destination subnets within SD-WAN rules. Option A is incorrect as it discusses precedence that is not relevant to the function of BGP tags. Option B is wrong because it misrepresents the role of route tags in relation to local preference. Option D is incorrect as it suggests a need for reconfiguration that is not necessary when using BGP tags for subnet identification.
