Free AWS Certified Developer Associate DVA-C02 Practice Question

When developing a cloud-based solution that exposes a set of HTTP endpoints to its users, which technique should a developer implement to ensure that each incoming request is both authenticated and authorized before granting access to the underlying resources?

  • Develop a bespoke authentication system within a Lambda function that generates and validates JSON Web Tokens before each service interaction.

  • Deploy AWS Security Token Service within the client’s scope to regularly assume an IAM role necessary for service interaction.

  • Integrate Amazon API Gateway with a Lambda authorizer that checks OAuth tokens for client identity verification on each interaction.

  • Configure the application to fetch and use static access credentials from AWS Systems Manager Parameter Store for each service request.
