I'm a bit confused about option C; it seems off to me, but I can't remember the details about DSCP marking for different applications.

I think option A sounds familiar, but I can't recall if it's specifically about Layer 2 traffic marking.

I remember something about DSCP bits being set for applications, but I'm not sure if it's per routing instance or not.

I practiced a question similar to this, and I feel like E might be true since it mentions the internal forwarding class.

Hmm, I'm not sure. The "cannot connect to a running instance" option seems a bit concerning. I'll need to double-check my understanding of how the web adapter works.
