Question 1

The developer has deployed the application successfully as part of an AWS CodePipeline continuous integration and continuous delivery (CI/CD) process.

The CloudFormation template contains the following resource types:

• AWS::ApiGateway::RestApi

• AWS::ApiGateway::Resource

• AWS::ApiGateway::Method

• AWS:ApiGateway::Stage

• AWS::ApiGateway:;Deployment

The developer adds a new resource to the REST API with additional methods and redeploys the template. CloudFormation reports that the deployment is successful and that the stack is in the UPDATE_COMPLETE state. However, calls to all new methods are returning 404 (Not Found) errors.
