What is the purpose of a Lambda alias?

To provide a stable ARN that can point to different versions of the function.

To set the memory size for the function.

To store environment variables for the function.

To trigger the function on a schedule.

A developer is using ECS with Fargate. They have a CI/CD pipeline that builds a Docker image and pushes it to Amazon ECR. They want to deploy the image to a 'test' environment for integration testing, but they need to ensure that the 'test' environment uses the exact image that was built, not a newer one. What is the best practice?

Tag the image as 'latest' and reference 'latest' in the test task definition

Tag the image with the Git commit SHA and reference that tag in the test task definition

Use a separate ECR repository for test images

Manually copy the image to the test environment after each build

In AWS Amplify, how can a developer create a separate environment for integration testing of a frontend application?

By adding a new branch in the repository and connecting it to Amplify.

By changing the build settings in the Amplify console.

By using AWS CloudFormation to create a separate stack.
