A DevOps Team Wants to Implement Their Containerized Application Using

question 4

Multiple Choice

A DevOps team wants to implement their containerized application using AWS. The deployment must meet the following requirements: There should be minimal downtime during deployment. The application must be functionally tested to be considered a success. How can the DevOps team automate this deployment?

• A) Use AWS Elastic Beanstalk with a multi-Docker container solution stack. Select immutable updates as a deployment strategy. Select enhanced health as a monitoring type in the Elastic Beanstalk environment to ensure health checks are transmitted at deployment.
• B) Use an Amazon ECS cluster and service with an Application Load Balancer and an AWS CodeDeploy blue/green deployment type. Define a production port and a test port in Amazon ECS. Write an AWS Lambda function to test the application, and reference it within the AfterAllowTestTraffic hook in the appspec.yml.
• C) Use AWS CloudFormation to provision Amazon EC2 instances behind an Application Load Balancer. Deploy the containers using Amazon ECS. Upon deployment, replicate the configuration in the new EC2 instances, perform testing, and switch traffic from the old Application Load Balancer to the new one using Amazon Route 53.
• D) Use an Amazon ECS cluster and service along with Amazon EC2 instances and an Application Load Balancer. Select rolling update as a deployment strategy. Add a Docker health check within the task definition to ensure rollback if the health check fails.

Definitions:

Chiral Molecule

A molecule that cannot be superimposed on its mirror image, often having a carbon atom bonded to four different groups.

Chiral

Describes a molecule that has a non-superimposable mirror image, often leading to molecules with distinct left-handed (S) and right-handed (R) configurations.

Achiral

Describing a molecule that is superimposable on its mirror image, indicating it has no handedness or enantiomers.

Enantiomers

Molecules that are mirror images of each other but cannot be superimposed on each other, much like left and right hands.
