I used whizlabs as my primary testing source. I had previously used whizlabs and they were excellent for Developer associate and Solutions Architect associate but the Sys Ops practice exams need some overhaul.
I recommend purchasing Jon Bonso’s practice exams from Udemy as they provide more realistic test questions with more focus on Cloudformation/organizations/ELB and other Sys Ops topics as well as more in-depth scenario questions than what Whizlabs currently has.
I also suggest whizlabs to include more topics related to each of the 5 domains tested on this exam as they currently all fall under one domain on your exams.
Thanks whizlabs for your materials but I would suggest those looking for solid exams to also purchase an alternative exam source like Jon Bonso’s exams on Udemy.
As for me, I plan to re-sit the test this upcoming Friday after having gone through more studying. Best of luck to all!
