AWS Certified Developer Associate DVA-C02 Practice Question

The correct answer is the Serverless Application Model, which provides a streamlined way for defining functions, APIs, and the event source mappings that trigger them. It also supports configuration variants for different stages of deployment, such as development and production. This simplifies the process and makes it efficient for developers to manage serverless applications in a multi-environment setup.

The other options, like the service for deploying web applications or the deployment automation service, do not offer the same level of simplicity and direct support for serverless architecture templating. The infrastructure as code service is also capable of defining resources but does not offer the simplified syntax and tools that are tailored for serverless applications like the Serverless Application Model does. The Cloud Infrastructure Development Kit is a more generic tool for defining cloud resources using familiar programming languages and could be used for these purposes, but it doesn't offer the same level of convenience for serverless deployments specifically.
