A Web Application Runs on Amazon EC2 Instances and Accesses

question 509

Multiple Choice

A web application runs on Amazon EC2 instances and accesses external services. The external services require authentication credentials. The application is deployed using AWS CloudFormation to three separate environments: development, test, and production. Each environment requires unique credentials for external services. What option securely provides the application with the needed credentials while requiring MINIMAL administrative overhead?

• A) Pass the credentials for the target environment to the CloudFormation template as parameters. Use the user data script to insert the parameterized credentials into the EC2 instances.
• B) Store the credentials as secure strings in AWS Systems Manager Parameter Store. Pass an environment tag as a parameter to the CloudFormation template. Use the user data script to insert the environment tag in the EC2 instances. Access the credentials from the application.
• C) Create a separate CloudFormation template for each environment. In the Resources section, include a user data script for each EC2 instance. Use the user data script to insert the proper credentials for the environment into the EC2 instances.
• D) Create separate Amazon Machine Images (AMIs) with the required credentials for each environment. Pass the environment tag as a parameter to the CloudFormation template. In the Mappings section of the CloudFormation template, map the environment tag to the proper AMI, then use that AMI when launching the EC2 instances.
