I think C is correct. Firewalls can't inspect encrypted traffic.

Okay, I remember learning that classless routing supports VLSM and discontiguous networks, so option D is the other correct answer.

This seems like a straightforward question about the STP process. I'll carefully read through the options and think about the logical next step after establishing overall strategies.
