It’s a fun exam Jody — it’s tough for sure, but its also the most logical of the three exams i’d say. The skills tested are required if you are working with a larger/hybrid AWS & On-premise network.
Let me know if you want any pointers at any point — i could probably help with some targeted suggestions If i know a bit about your background & skill-set. No pressure but the offer is there.
