It was an unforgettable Christmas as I finally cleared the AWS SAP exam at almost the last minute of Year 2022.

It was also a fantastic year for me. I achieved all my goals which I planned at the beginning of the year.

I may just stop here for now and next year, I will spend more time on my [Youtube Channel](https://www.youtube.com/@startquicktech2017) and this [Medium Blog](https://startquicktech.medium.com/) on sharing my experience and knowledge on Cloud and IT. I hope I can help more people to start their journey to the Cloud World.

Let’s get back to the exam preparation.

Firstly, I would like to say this is not a short article. It covers all the aspects for the exam at least based on my preparation. Secondly, you cannot pass the exam via just reading this article. Instead, you need to spend lots of time to do document reading and hands-on practise.

### **Learning Materials**

I know you might be interested in the materials that I use. I did two training sessions on Udemy but honestly, I haven’t finished all of them.

If you are beginner who is preparing Solution Architect Associate Exam, you can also use this course from DolfinED for a broader and deeper knowledge. But unfortunately, it is not allowed to enrol on Udemy. I just found this [**website**](https://www.dolfined.com/courses/aws-certified-solutions-architect-professional) which has the same content. This course has more than 40 hours videos and it covers **everything.** But for the experienced AWS engineer, I would not suggest this as it takes too long time to go through the videos and lots of concepts which are a bit boring.

Another course I use is from [**Neal Davis SAP-02 course on Udemy**](https://www.udemy.com/course/aws-certified-solutions-architect-professional-training/learn/lecture/25364938). It has only 20-hour video and the knowledge is explained quite clearly. Compare with the [exam guide](https://d1.awsstatic.com/training-and-certification/docs-sa-pro/AWS-Certified-Solutions-Architect-Professional_Exam-Guide.pdf), the knowledge which is covered in this course is not 100% but you can definitely pass the exam with high score. Also, I would like to emphasise that this exam is not just testing if you remember the knowledge, instead, it test if you know how to use the knowledge to build a proper solution. **Remember, there is no best solution in the world. A better one is always the one you should select.**

Other than the training course, you should do some practice exam. I used [**Jon Bonso’s practice exam on Udemy**](https://www.udemy.com/course/aws-solutions-architect-professional-practice-exams-sap-c02/learn/quiz/4473244) which cost me just $9.99 when it is in discount. I did three of them but only passed one. But don’t worry, this will not impact your final result in the real exam as the more mistakes you make, the more knowledge you know you misses. The explanations are very in details and I would suggest you to go through the explanation for the correct and incorrect answers no matter you make the right choice or not. If you still don’t understand it, go to AWS official document and do some hands-on as well.

Most importantly, for my last 5-year learning and working on AWS, I read lots of [AWS architecture blogs](https://aws.amazon.com/blogs/architecture/) and [AWS re:Invent videos on Youtube](https://www.youtube.com/results?search_query=aws+reinvent). These help a lot and I found some of the questions are coming from them which are real customer use case. Also, [AWS white-papers](https://aws.amazon.com/whitepapers/?whitepapers-main.sort-by=item.additionalFields.sortDate&whitepapers-main.sort-order=desc&awsf.whitepapers-content-type=*all&awsf.whitepapers-global-methodology=*all&awsf.whitepapers-tech-category=*all&awsf.whitepapers-industries=*all&awsf.whitepapers-business-category=*all) are highly recommended! Below two are must-read which I recommended many times in my previous blogs:

- [AWS Well Architected Framework](https://d0.awsstatic.com/whitepapers/architecture/AWS_Well-Architected_Framework.pdf)
- [AWS Web Hosting Best Practice](https://d0.awsstatic.com/whitepapers/aws-web-hosting-best-practices.pdf)

### Learning Plan

Not like DevOps Engineer Pro exam, I just spend less than a month to prepare this course as I have already got quite a lot of experience on the scope of the exam requirements.

For the first two weeks, I spend 2–3 hours a day to watch the Neal’s training video and do some hands-on at the same time. I ignored some sessions such as S3, EC2, RDS… which I believe I have mastered so it saved me quite a lot of time. But for the knowledge that I was not so familiar with such as Direct Service, Direct Connect, I watched them for multiple times.

For the last 2 weeks, I started to do practice exams. Most of the time, I cannot have a full-3-hour time to do the exam but I tried to do it within a day. And after that, I will spend 2–3 days to go through all the questions and answers. Then go back to the knowledge and do hands-on if I am still not so sure. I use Microsoft OneNote as my notebook to record all the knowledge I know and I missed based on different services.

And before the exam, I will just go through my notes multiple times to remember them. Because **in the real exam, you will make the wrong choice just because you don’t know or you forget an unimportant knowledge point. If this happens multiple times in the exam, you might lose your patience and focus.**

As I mentioned in below video, you should first know the key concepts of Cloud Compute and the corresponding services on AWS.

{% youtube mIIw3rnJOgY %}

Before I walk you through the knowledge and key points, I would suggest you to learn multi-tier/3-tier architecture.

There are four domains for SAP-02 exam based on the exam guide.

- Design for organisational complexity
- Design for new solutions
- Continuously improve existing solutions
- Accelerate workload migration and modernisation

But I will not follow this. I will show you the knowledge structure based on my own priorization.

I broke the services into three levels based on the importance and popularities and also point out the key info related to each service. Don’t take this as you knowledge checklist as it does not cover all. But you can go through them and see if you have covered them.

### **Level 1 (Most Important — Need deep understanding and familiar with hands-on operations)**

- AWS Organization — For SA Pro, this is a the most critical service which can be connected to different aspects of the Cloud services. More than 1/3 of the questions are related to AWS Organization. You need to know how it works with SCP, SSO, Billing, CloudTrail
