question 24

Multiple Choice

A company wants to implement a CI/CD pipeline for building and testing its mobile apps. A DevOps Engineer has been given the following requirements: Use AWS CodePipeline to orchestrate the workflow. Test the application on real devices. Trigger a notification. Stage the application binary on a production bucket in a different account. Make the application binary publicly accessible. Which sequence of actions should the Engineer perform in the pipeline to meet the requirements?

• A) Use AWS CodeCommit as the code source and AWS CodeDeploy to compile and package the application. Use CodeDeploy to deploy the application binary to an AWS Lambda function for testing. Use a third-party library on AWS Lambda to simulate the device platform. Allow a Lambda role to upload to the production Amazon S3 bucket. Make the binary publicly accessible. Trigger notifications using Amazon SNS.
• B) Use GitHub as the code source and AWS Lambda to compile and package the application. Use another Lambda function to run unit tests and deliver the application binary to a development bucket. Use the binary from the development bucket and install the application on a personal device for testing. Deliver the binary to the production bucket after approval. Trigger notifications using Amazon SNS.
• C) Use an Amazon S3 bucket as the code source and AWS CodeBuild to compile and package the application. Use AWS CodeDeploy to deploy the application binary to a device farm for testing. Deliver the binary to the production S3 bucket. Use an S3 bucket policy to allow public read on the production S3 bucket. Trigger notifications using an Amazon CloudWatch Events rule with Amazon SNS.
• D) Use AWS CodeCommit as the code source and AWS CodeBuild to compile and package the application. Invoke an AWS Lambda function that uploads the application binary to a device farm for testing. Deliver the binary to the production Amazon S3 bucket. Use an S3 bucket policy to allow public read on the production S3 bucket. Trigger notifications by using an Amazon CloudWatch Events rule.
