Which behavior describes a WAN Edge router running dual DIA when its DPI engine has identified a cloud SaaS application?
A.
The gateway WAN Edge router DPI engine accepts the DNS query for SaaS applications, and DNS queries for noncloud applications follow the explicit path.
B.
The WAN Edge DPI engine never selects a subperforming DIA circuit for the first application, and the WAN Edge router finds the SaaS application.
C.
Existing flows change the path and drop the traffic when the performance of the chosen path degrades.
D.
Application traffic flows are routed over best performing DIA circuit, which makes the routing decision based on the best performing path.
When a user onsite connects for the first time to one of the Software-as-a-Service apps, the user's device initiates a DNS query for the apps' URL, and the following chain of events visualized below happen:
1. The WAN edge router's DPI engine intercepts the user's DNS query. If the host DNS query is for the Cloud onRamp SaaS application, the vEdge router forwards it over the best performing circuit to the DNS server that is defined for this ISP.
2. DNS queries for non-Cloud onRamp applications are forwarded according to the routing table towards the SD-WAN overlay fabric
The answer is D
I also think D:
