A developer is using CloudFormation to provision a test environment for an application. They want to ensure that the test environment is isolated from production and can be deleted easily when testing is complete. What is the best practice?

Manually create the test resources and delete them when done

Create a separate CloudFormation stack for the test environment

Use the same stack as production and add a test environment parameter

Use a nested stack for test resources within the production stack

What is the benefit of defining test events in an AWS SAM template?

They automatically deploy the function to all environments.

They replace the need for unit tests.

They are required for the template to be valid.

They allow developers to validate resource configurations and test functions locally with consistent sample data.

A developer has created an API Gateway REST API and wants to deploy it to a 'test' environment so that the QA team can validate the integration before production. What is the correct way to do this?

Deploy the API to a stage named 'test' using the API Gateway console or AWS CLI

Create a new API Gateway API for the test environment and configure it identically

Create a new API Gateway domain name for the test environment

Use a Lambda alias to point to a test version and invoke the API through that alias

A developer wants to test a new version of a Lambda function in an integration environment without affecting production. Which approach should be used?

Delete the production alias and recreate it after testing.

Create a new alias 'test' and point it to the new version.

Use the same alias for both production and testing.

Update the function code directly in the '$LATEST' version.

A developer has an API Gateway API with a 'dev' stage and a 'prod' stage. They want to enable throttling for the 'prod' stage but not for 'dev'. What is the correct way to achieve this?

Enable throttling in the Lambda function configuration

Create a usage plan and associate it with the 'prod' stage

Configure throttling at the API level, which applies to all stages

Use a custom domain name for the 'prod' stage and configure throttling there
