Just did the exam today.
What should I say: 64 questions of 65 questions are completely different to the whizlabs questions.
I completed all Whizlabs practice tests with 65 questions in ~1 hour.
The Real World exam took me 2 hours with a lot of headache.
Don`t think that you will be safe with the whizlabs questions and a simple aws training
Be familiar with RDS, ELB, Lambda, API Gateway and have a good understanding of the architecture and - be really careful with the questions wording. It was much more tricky than I thought.
They concentrate on application design around aws and on prem mix including several services.
Whizlabs - you need to update the questions very soon!
