A company has many applications. Different teams in the company developed the applications by using multiple languages and frameworks. The applications run on premises and on different servers with different operating systems. Each team has its own release protocol and process. The company wants to reduce the complexity of the release and maintenance of these applications.

The company is migrating its technology stacks, including these applications, to AWS. The company wants centralized control of source code, a consistent and automatic delivery pipeline, and as few maintenance tasks as possible on the underlying infrastructure.

What should a DevOps engineer do to meet these requirements?

A. Create one AWS CodeCommit repository for all applications. Put each application's code in different branch. Merge the branches, and use AWS CodeBuild to build the applications. Use AWS CodeDeploy to deploy the applications to one centralized application server.

B. Create one AWS CodeCommit repository for each of the applications Use AWS CodeBuild to build the applications one at a time. Use AWS CodeDeploy to deploy the applications to one centralized application server.

C. Create one AWS CodeCommit repository for each of the applications. Use AWS CodeBuild to build the applications one at a time to create one AMI for each server. Use AWS CloudFormation StackSets to automatically provision and decommission Amazon EC2 fleets by using these AMIs.

D. Create one AWS CodeCommit repository for each of the applications. Use AWS CodeBuild to build one Docker image for each application in Amazon Elastic Container Registry (Amazon ECR). Use AWS CodeDeploy to deploy the applications to Amazon Elastic Container Service (Amazon ECS) on infrastructure that AWS Fargate manages.

A development team is building an ecommerce application and is using Amazon Simple Notification Service (Amazon SNS) to send order messages to multiple endpoints. One of the endpoints is an external HTTP endpoint that is not always available. The development team needs to receive a notification if an order message is not delivered to the HTTP endpoint.

What should a DevOps engineer do to meet these requirements?

A. Create an Amazon Simple Queue Service (Amazon SQS) queue. On the SNS topic, configure a redrive policy that sends undelivered messages to the SQS queue. Create an Amazon CloudWatch alarm for the new SQS queue to notify the development team when messages are delivered to the queue.

B. Create an Amazon Simple Queue Service (Amazon SQS) queue. On the HTTP endpoint subscription of the SNS topic, configure a redrive policy that sends undelivered messages to the SQS queue. Create an Amazon CloudWatch alarm for the new SQS queue to notify the development team when messages are delivered to the queue.

C. On the SNS topic, configure an HTTPS delivery policy that will retry delivery until the order message is delivered successfully. Configure the backoffFunction parameter in the policy to notify the development team when a message cannot be delivered within the set constraints.

D. On the HTTP endpoint subscription of the SNS topic, configure an HTTPS delivery policy that will retry delivery until the order message is delivered successfully. Configure the backoffFunction parameter in the policy to notify the development team when a message cannot be delivered within the set constraints.
