Tips and Tricks to pass the AWS Certified Developer Associate Exam

Many organizations have their own cloud services, resulting in fierce competition with other cloud services to be the best. Amazon Web Services (AWS) is one of the top cloud services, with a positive impact on individuals and businesses worldwide. The AWS Certified Developer Associate (DVA-C01) exam is designed for developers with one or more years of experience creating and supporting AWS-based applications.

AWS service includes features like Data encryption and various access controls which provide data security over the cloud. AWS can also host dynamic websites that run various web and application servers. It also includes the ability to work with hybrid abilities.

This exam, on the other hand, assesses your knowledge of:

  • To begin, demonstrate knowledge of core AWS service uses and fundamental AWS architecture best practices.
  • Second, use AWS to demonstrate proficiency in designing, deploying, and troubleshooting cloud-based applications.
