Nowhere in the question it is mentioned that the sites have also an MPLS circuit, so, having DIA at each site cannot alleviate traffic from some non-existent MPLS circuits, but it can be used to speed up the deployment via ZTP

A & C. Option E is for deployment in MPLS circuits. The solution in asking for deploying SDWAN on DIA circuits.

it's a A and C. The question doesn't even mention MPLS, so E doesn't make sense. ZTP is a major benefit.

I agree with A and E. From OCG states "With DIA, Internet-bound traffic or public cloud traffic from the branch is routed directly to the Internet, avoiding the latency involved in tunneling Internet-bound traffic to a central site." This corresponds to answer A. And then "Benefits of using DIA include reduced bandwidth consumption, latency, and costs (thanks to offloading Internet traffic from the private WAN circuit)." Meaning that basically offloads internet traffic from the MPLS (private WAN) and routed directly to DIA. SD-WAN cannot increase by itself, only ISP can do that.

A is correct, but why E? The solution is using DIA, not MPLS.

I agree with A and E by instinct alone. DIA is configured on the edge router way after you get access to it, i don't think ZTP is applicable.
