Exam NSE7_SDW-7.2 topic 1 question 27 discussion

D is incorrect. SG p 180: "when you enable SD-WAN on FortiGate, FortiOS hides the v4-ecmp-mode setting and replaces it with the load-balance-mode setting" C is correct. SG p 311: Order of route lookup precedence = Policy Routes > ISDB routes > SD-WAN rules > route-cache > RIB/FIB. THus, if traffic matches any proute, the traffic would be routed by proute, not by SD-WAN rule.

Answer A and D

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. 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" ?

AC Studi guide page 150 If the session matched the SD-WAN implicit rule, and therefore was handled using standard FIB routing, these SD-WAN fields do not appear.

A & C are correct
