Prepare for the exam

In my case, since I am familiar with AWS in my current professional role as a data / devops engineer, I only spent 5 nights revising all AWS exam materials. It is crucial to set out a timeline based on your AWS competency, and give yourself enough time to comprehend all the chapters.

Below are some high level notes I have gathered and prepared:

  1. Start with Their videos content are excellent and sufficient to cover the most important sections of the exam.
  2. Explore the popular AWS services’s FAQs: VPC, RDS, EC2, S3 and IAM. More than 15% of the exam questions are actually in the FAQs section.

On the exam day

  • Be early. Give yourself at least 20 minutes because there are check-in processes at the exam center.
  • Aim for the easy questions first, skip and revisit the complicated ones later at the end.
  • Read questions, and of course, all the options carefully. You are asked to choose the most effective answers, not only the right answer.
  • Be aware of exam timing. Try not to spend more than 2 minutes on a single problem, deal with it later.

That is all I have. Thank you and I wish you best of luck in your AWSSA-A exam.
