Refer to the exhibit.
The exhibit shows the SD-WAN rule status and configuration.
Based on the exhibit, which change in the measured latency will make T_MPLS_0 the new preferred member?

Correct Answer: BD
The SD-WAN rule seeks the link with the least latency for traffic management. The link-cost-threshold is set to 10, meaning a link will get selected if its latency is 90% or less than that of the current preferred link. In the exhibit, T_INET_0_0 has a latency of 101.349 ms. For T_MPLS_0 to become the new preferred member, its latency needs to be under 101.349 ms * 0.9, which is approximately 91.2141 ms. Option B, where T_MPLS_0 has a latency of 100 ms, meets this criterion and will not be correct. Instead, it satisfies the closest remaining requirement for the threshold. Therefore, option B is the most likely answer.

TheUsDOption: B
Oct 26, 2023Not sure why people are posting "D" as the answer. It is not an interface showing on the exhibits. Because of this, "B" "When T_MPLS_0 has a latency of 100 ms." should be the correct answer. Did someone make a major typo?

PoBratskyOption: D
Jan 8, 2024D is correct. I think T_N1PLS_0 is T_MPLS_0 real metric / (1 + link cost threshold / 100) = CM (Correct metric) 101.349 / (1 + 10 / 100) = CM 101.349 / 1.1 = 92.13545454545455 T_MPLS_0 - 80ms < T_INET_0_0 - 92 Preferred member is T_MPLS_0

Jun 18, 2023Official study guide, page 174. link-cost-treshold is set to 10 (percent) so the other link must have a latency of less than 90% of the preferred link

TcmhOption: D
Jun 29, 2023D Link-cost-threadhold =10 so actual latence of INT_0_0 = 101.349 * 0.9 =91.2141 so Int_MPLS less than 91.2141 to take over, so D is correct
