Selected Answer: A A. 6 The BFD multiplier in application-aware routing is a user-configurable setting that determines the time used to calculate mean loss, mean latency, and mean jitter. This value is multiplied by the polling interval to set the time for these calculations. The default value for the BFD multiplier in application-aware routing is 6.

This is not for AAR policy. It's the standard BFD configuration setting multiplier. For app-route monitoring BFD multiplier value is 6. So option is A.

Selected Answer: A Lab settings: bfd default-dscp 48 bfd app-route multiplier 6 bfd app-route poll-interval 600000

B is correct

Selected Answer: B The correct answer is B

Selected Answer: B The Multiplier value tells how many consecutive BFD probes have to be lost before a vEdge router declares a tunnel down, as shown in figure 3 below. The BFD default values in Cisco SD-WAN are hello-interval 1000msec, multiplier 7, and dscp value of 48 . https://www.networkacademy.io/ccie-enterprise/sdwan/application-aware-routing-app-route-policy#:~:text=The%20Multiplier%20value%20determines%20how,illustrated%20in%20figure%203%20below.&text=The%20BFD%20default%20values%20in,and%20dscp%20value%20of%2048%20.

Sorry, wrong answer, the correct answer is A

A is correct

Selected Answer: B It seems that with AAR it differs from the default BFD multiplier in a normal SDWAN tunnel ... The BFD default values in Cisco SD-WAN are hello-interval 1000msec, multiplier 7, and dscp value of 48 https://ccieme.wordpress.com/2021/02/08/sd-wan-application-aware-routing/ https://www.networkacademy.io/ccie-enterprise/sdwan/application-aware-routing-app-route-policy
