You Have Been Asked to Use Your Departments Existing Continuous

question 374

Multiple Choice

You have been asked to use your departments existing continuous Integration (CI) tool to test a three-tier web architecture defined In an AWS CloudFormation template. The tool already supports AWS APIs and can launch new AWS CloudFormation stacks after polling version control. The CI tool reports on the success of the AWS CloudFormation stack creation by using the Describe Stacks API to look for the CREATE COMPLETE status. The architecture tiers defined in the template consist of: - One load balancer - Five Amazon EC2 instances running the web application - One multi-AZ Amazon ROS instance How would you implement this? (Choose two.)

• A) Define a WaitCondition and a WaitConditionHandle for the output of a UserData command that does sanity checking of the application's post-install state.
• B) Define a CustomResource and write a script that runs architecture-level Integration tests through the load balancer to the application and database for the state of multiple tiers.
• C) Define a WaitCondition and use a WaitConditionHandle that leverages the AWS SDK to run the DescribeStacks API call until the CREATE COMPLETE status is returned.
• D) Define a CustomResource that leverages the AWS SDK to run the DescribeStacks API call until the 'CREATE COMPLETE status is returned.
• E) Define a UserDataHandle for the output of a UserData command that does sanity checking of the application's post-install state and runs integration tests on the state of multiple tiers through the load balancer to the application.
• F) Define a UserDataHandle for the output of a CustomResource that does sanity checking of the application's post-install state.
