How is each individual application monitored on a per-user basis in the overlay network?
Answer: D
Individual applications are monitored per user through performance measurements, which reflect the quality of the application experience across the overlay network.

Refer to the exhibit. vEdge102 must establish a control connection across MPLS by using TLOC extension and dynamic routing. Which configuration accomplishes this task?
Answer: C
A Layer 3 TLOC extension requires dynamic routing between the WAN edge devices. vEdge102 must form BGP with vEdge101 at 172.1.1.2 and make its 172.1.1.1/30 link a tunnel interface using the restricted MPLS color. This provides reachability through vEdge101’s MPLS transport for vEdge102’s MPLS control connection. Cisco documents that Layer 3 TLOC extension requires a routing protocol between the SD-WAN devices and uses a tunnel interface for the extended TLOC.

Question 3 · Architecture Open
What is the BFD multiplier used in application-aware routing?
Answer: A
The BFD multiplier specifies how many consecutive BFD packets may be missed before the path is considered down. For Cisco SD-WAN application-aware routing, the multiplier is 6.
