Great experience! I did have a concern about one of the questions in the exams though.

There is a Drag-And-Drop question in “Timed Mode Set 2” (Question 7) that does not specify or mention how I should order the list for Defense-In-Depth: either the “lowest” layer (Data) FIRST or the “lowest” layer (Data) LAST. All of the visual models I have seen for Defense-In-Depth have “Data” at the bottom of the list (the thing that we are trying to protect), so I assumed that meant you would need to choose “Data” first, and then every layer after that increments from there, up to Physical Security at Layer 7 (like the Solar System).

I think a brief note like “order these from the First line of defense (First), to the last line of defense (Seventh)” would help.

Other than that, great job on the questions, and thank you for the wealth of knowledge in the explanations for the answers!
