AWS Solutions Architect Associate Certification - Everything you need to know

In its official sources, AWS recommends taking the exam when we already have at least one year of experience in working with the platform. Having practical experience is useful, but not essential. If you have already started exploring the AWS cloud, this is a good time to consider whether it is worth starting to prepare for this exam. If you do not have an account with AWS yet, there is no other starting route than registration. AWS offers Free Tier, during which you have the opportunity to use many services at no cost. Solution Architect Associate exam is the best choice to start with the AWS certification route. Its scope is quite wide, but not too detailed. It is also a great way to start your adventure with the cloud. While studying for the exam, you will have a chance to gain and consolidate your knowledge.

Preparation materials for the AWS Solution Architect Associate exam

Below, I have compiled a list of courses and training materials that are noteworthy. Some of them are paid, and some of them are free.

Practical tips for the AWS SAA exam

  • you can come back to any of the exam questions later. Additionally, you can flag a specific question to make it easier for you to find it
  • the first time you go through the questions, try not to spend more than 2 minutes per question. If you are unsure of the answer, flag the question and come back to it later
  • there is a chance that you will find a clue to some questions in other questions or answers
  • try to answer the questions using the method of elimination. It often happens that part of the answer is easy to drop by reducing our choice to 2 options that differ in one detail
  • use the full exam time, if you have already answered all questions, use the remaining time to retake the exam from start to finish and do a diligent review
  • you may not have any supporting materials, equipment or food with you when you pass the exam at the examination center. The center only provides a sheet of paper and a pen.

Online exam

  • when starting the online exam, you will be asked to show exactly where you are taking the exam. During the exam itself, you will be constantly supervised by a proctor using a camera and microphone
  • it is a good idea to log into the application provided by the certification center the day before to test the internet connection and check if the application is working properly
  • during the online exam, he must ensure that no one disturbs you in any way. It is unacceptable that any of the household members enter the room where you are taking the exam. There is also a point in the regulations that too much noise from your location (e.g. from the next room or from behind the window) may result at the end of the exam and failure.
