Which two statements are correct when traffic matches the implicit SD-WAN rule? (Choose two.)
Which two statements are correct when traffic matches the implicit SD-WAN rule? (Choose two.)
When traffic matches the implicit SD-WAN rule, the session information output will not display SD-WAN-specific details because the traffic is handled using standard FIB routing. Additionally, traffic that matches the implicit SD-WAN rule does not match any of the entries in the policy route table. This implicit rule serves as a fallback mechanism when no other SD-WAN rules apply.
A. correct - If the session matched the SD-WAN implicit rule, and therefore was handled using standard FIB routing, these SD-WAN fields do not appear. page 149 C. correct - if traffic doesnt match any entry in the proute table then it will use the implicity deny SD-WAN rule D. wrong - load-balance-mode replaces v4-ecmp-mode when SD-WAN is enabled - page 179 B. therefore B is wrong
should be C and D
Why not "D" ?
Because v4-ecmp-mode is replaced by load-balance-mode when SDWAN is enable.
The other statements, B and D, are not correct because: B. All SD-WAN rules have the default and gateway setting enabled. This is not necessarily true for the implicit rule, as it functions as a fallback and does not need explicit default and gateway settings enabled in the context of user-defined SD-WAN rules. D. Traffic is load balanced using the algorithm set for the v4-ecmp-mode setting. This statement may be partially correct in some contexts, but it does not specifically apply to traffic matching the implicit SD-WAN rule, which is more about the traffic not matching any of the defined rules rather than how it gets load balanced. The implicit rule typically uses default routing behavior rather than any special load balancing algorithm.

A & C are correct
