question 202

Multiple Choice

A DevOps engineer is creating a CI/CD pipeline for an Amazon ECS service. The ECS container instances run behind an Application Load Balancer as the web tier of a three-tier application. An acceptance criterion for a successful deployment is the verification that the web tier can communicate with the database and middleware tiers of the application upon deployment. How can this be accomplished in an automated fashion?

• A) Create a health check endpoint in the web application that tests connectivity to the data and middleware tiers. Use this endpoint as the health check URL for the load balancer.
• B) Create an approval step for the quality assurance team to validate connectivity. Reject changes in the pipeline if there is an issue with connecting to the dependent tiers.
• C) Use an Amazon RDS active connection count and an Amazon CloudWatch ELB metric to alarm on a significant change to the number of open connections.
• D) Use Amazon Route 53 health checks to detect issues with the web service and roll back the CI/CD pipeline if there is an error.
