QUESTION 61
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 2 answers

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.

QUESTION 41
Your company currently runs a large multi-tier web application. One component is an API service that all other components of your application rely on to perform read/write operations.
This service must have high availability and zero downtime during deployments.
Which technique should you use to provide cost-effective, zero-downtime deployments for this component?

A.    Use an AWS CloudFormation template to re-deploy your application behind a load balancer, and launch a new AWS CloudFormation stack during each deployment.
Update your load balancer to send traffic to the new stack, and then deploy your software. Leave your old stacks running, and tag their resources with the version for rollback.
B.    Re-deploy your application on Elastic Beanstalk. During deployment, create a new version of your application, and create a new environment running that version in Elastic BeanStalk. Finally, take advantage of the Elastic Beanstalk Swap CNAME operation to switch to the new environment.
C.    Re-deploy your application behind a load balancer that uses Auto Scaling groups. Create a new identical Auto Scaling group and associate it to your Amazon Route53 zone.
Configure Amazon Route53 to auto- weight traffic over to the new Auto Scaling group when all instances are marked as healthy.
D.    Re-deploy your application behind a load balancer using an AWS OpsWorks stack and use AWS OpsWorks stack versioning, during deployment create a new version of your application, tell AWS OpsWorks to launch the new version behind your load balancer, and when the new version is launched, terminate the old AWS OpsWorks stack.
