AWS Certified Developer Associate Certification is not a hard Certification but certainly is not very easy. But for preparing, you need the following:
Quality video material not hours of waffle. This will provide the base understanding.
Quality lab exercises with quality documentation.
Identification of the individual sections of the AWS documentation that you required to know and testing on that knowledge.
There are several training courses to clear this certification exam. I recommend this AWS Developer Associate Certification course by Intellipaat to clear the AWS Certified Developer Associate certification.
