wtf is aws-dva-c02-practice-test?

This repository is a study guide for developers preparing for the AWS Certified Developer, Associate exam, known as DVA-C02. It provides preparation resources, study notes, exam topics, and practice strategies aimed at helping developers build confidence before sitting the certification. The certification itself validates a developer's ability to design, develop, deploy, and maintain applications on AWS, covering AWS application development, SDK usage, cloud deployment, security best practices, monitoring, troubleshooting, and how AWS services fit together. The guide points to a set of key AWS services worth studying, including AWS Lambda for serverless applications, Amazon API Gateway for building and managing APIs, Amazon DynamoDB for NoSQL databases, Amazon S3 for object storage, Amazon EC2 for compute workloads, AWS IAM for authentication and permissions, and Amazon CloudWatch for monitoring applications. It recommends supplementing this with hands-on practice: deploying applications, managing IAM permissions, using the AWS CLI, working with SDKs, configuring monitoring, and troubleshooting cloud applications, since the exam tests practical decision making rather than simple memorization. Study topics are grouped into four areas: serverless development, including Lambda functions and event-driven architecture, application security, covering IAM policies, authentication, and encryption, deployment and continuous integration, covering release management and AWS developer tools, and monitoring and troubleshooting, covering CloudWatch metrics and application debugging. The repository also lays out a four-week study plan, moving from AWS fundamentals in week one, through developer services like Lambda, APIs, databases, and storage in week two, deployment and monitoring in week three, and a final week of practice assessments and review of weak areas. Before the exam, the guide suggests you should be able to explain core AWS services, choose the right AWS solution for a given scenario, apply security best practices, deploy cloud applications, and troubleshoot them when something goes wrong. There is a placeholder section for adding an external link to additional resources, which is not filled in yet.
