Udemy AWS Certified Developer - Associate Practice Tests

  • Purchased the acloud guru AWS Certified Developer – Associate course from udemy (should get it for $10-$15 on discount) helps to get a clear picture of the the format, topics and relevant sections
  • Opinion : acloud guru course are good by itself but is not sufficient to pass the exam but might help to counter about 50-60% of exam questions
  • Signed up with AWS for the Free Tier account which provides a lot of the Services to be tried for free with certain limits which are more then enough to get things going. Be sure to decommission anything, if you using any thing beyond the free limits, preventing any surprises 🙂
  • Also, used the QwikLabs for all the introductory courses which are free and allow you to try out the services multiple times (I think its max 5, as I got the warnings couple of times)
  • Update: Qwiklabs seems to have reduced the free courses quite a lot and now provide targeted labs for AWS Certification exams which are charged
  • Read the FAQs atleast for the important topics, as they cover important points and are good for quick review
  • Did not purchase the AWS Practice exams, as the questions are available all around. But if you want to check the format, it might be useful.
  • You can also check practice tests

  1. Hi Jayendra,

    I am planning to write AWS Certified Developer – Associate Exam .

    Would you please share questions and answer , if you have ?

    Thanks

  2. Hi Jayendra,

    Which are the white papers I need to refer for AWS-Certified Developer Associate exam? (Please mention white papers needed for AWS-CDA only, not solution architect ones)

    Thank you for your time in advance.

    1. Hi Chitra, there are no specific Whitepapers for Developer. Also, none is listed in the AWS blue print.

      1. Thanks for quick response Jayendra, then which white papers I should refer to crack CDA exam? or I need not go through them? or any main specific ones?

  3. A Cloud Guru AWS Certified Developer – Associate (Practice Tests)

    you didn’t put a note whether the questions from this are similar to actual exam. was that intentional?

    1. Its intentional, I have not taken the A Cloud Guru tests and do not have users feedback as well, hence nothing is quoted for it.

  4. Hi Everyone,

    Hope the whole world is doing great. Thanks to Jayendrapatil for all his hard work!
