A team manages a serverless application using AWS SAM. They need to add a new environment variable to an existing Lambda function and update the deployment. The developer modifies the AWS SAM template and runs 'sam deploy'. What happens to the existing Lambda function?

The function is updated in place with the new environment variable, and the change is tracked as a new CloudFormation stack update.

The deployment fails because environment variables cannot be changed after a function is created.

The function is deleted and recreated with the new configuration.

The function remains unchanged, and the environment variable is only applied to new invocations.

How can you roll back a deployment that was performed using AWS CodeDeploy?

Manually SSH into each instance and revert the code

Redeploy the previous application revision to the same deployment group

Delete the deployment group and recreate it

Use the AWS Management Console to revert the EC2 instances to a previous AMI

In API Gateway, what is the purpose of a base path mapping?

To configure the SSL/TLS certificate for the custom domain

To map a custom domain name to a specific API stage

To define the root resource path for the API

To set up a DNS record for the custom domain
