Just passed the Developer Associate exam, studied for about 3 weeks.
This was my second Associate level exam after Solutions Architect.
Jon Bonso's practice tests for Developer Associate.
CI/CD (CodeCommit, CodeBuild, CodeDeploy, CodePipeline)
Encryption/Decryption (S3, KMS)
Overall I found the exam easier than solutions architect associate. Also would like to thank the #AWSCertfied challenge, it really help for the preparation and kept me motivated to get my 3rd AWS certification.
Feel free to check out my notes.
