Acing The AWS Cloud Practioner Certification (CLF-C01)
How I got 93.4% with 2 weeks of preparation!

This is the second part of the two-article set on my Cloud Computing journey. It covers how I prepared for the certification and what to expect on the exam day.
The first article I wrote was about why I chose to learn Cloud Computing, comparison of the learning paths & certification between AWS and Google Cloud followed with an overview of the AWS Cloud Practioner Exam. You can read the article here:

What to study?
I had booked the exam 2 weeks ahead. To be honest, I have very little knowledge of Cloud Computing on the day I booked the exam. I had read a few blogs on how much time it usually took for preparation, and added a week more to that. I feel another 10 days would have made things easier for me.
Now, I kept the preparation mantra simple: learn as much as I can retain while covering what is essential.
A bit of research helped me zero down to these three learning sources:
AWS Cloud Practioner Essentials (Second Edition): This is 6-hour training, and must I say, an absolute delight in terms of content. Concepts are explained such that a non-techie can grasp it easily (I am from Sales). There are a good number of examples to help you understand applicability in the real world. Link to this training is here.
An alternative to this training which few people have suggested is FreeCodeCamp course by Andrew Brown on YouTube which is about 3 hours long.
If you have time, I would strongly suggest you go for AWS training, not only because you would be learning it from horses’ mouth, but also because you would get a certificate of completion for this training, which is sharable as a badge on LinkedIn and other social media platforms. That is a good motivation in itself! Also, this training has an exam in the end, which is a simpler version of the certification exam but gives you a glimpse of what to expect.
AWS Overview Whitepaper: There are many whitepapers available on AWS site which you can refer to, but the absolute must is this one. All 95 pages of it!
Overall, AWS provides about 175 services and the Cloud Practitioner training will not cover all of them. You will have to supplement the training with this document.
Practice tests: I purchased the 6-set practice set at Udemy. It was highly recommended by many, and I was not disappointed!
Now the passing mark for CLF-C01 exam is 70%. In the first practice test, I got 69% and failed. I spent a good amount of time going through explanations of the ones I got wrong and reading the material around it.
I kept noting the areas I was consistently faring poorly in and spent time brushing them up. In total, I was able to give 5 practice exams and got between 75%- 85%.
I was not expecting 93.4% as my test result, given that I had not crossed 85% in any practice exam. The practise tests are a tad bit harder than the actual exam. Here is my exam result:

How I studied?
- Day 1- Day 4: Spent about 2.5 to 3 hours each day to get the AWS training completed. The is the actual time spent on studying, not including breaks. Now the training is about 6 hours long, but I was taking notes and screenshots as I was going through the training to help me revise later, hence the extra hours.
- Day 5: Revised the training and gave the training test. Got the completion certificate, felt overjoyed!
- Day 6- Day 10: Went through AWS Overview Whitepaper at a slower pace. There is too much content (remember, 175 services!) packed in these 95 pages. Few sections would be a repeat of what you would have already covered in the AWS training.
- Day 11- Day 13: Revised my training notes and whitepaper and gave 5 practice tests. I had to re-read sections on Pricing, Support Plans, Shared Responsibility Model and Well-architected Framework as I was getting many of those questions wrong.
- Day 14: Test.
I hope you found some clarity about the exam by now. If you have any questions, you can leave a comment below or message me on my LinkedIn, would be happy to help! Let me know how your exam went if you found this article helpful😊
All the best!
