Exam AWS DevOps Engineer Professional topic 1 question 176 discussion

Exam question from Amazon's AWS DevOps Engineer Professional
Question #: 176
Topic #: 1
[All AWS DevOps Engineer Professional Questions]

A company deploys updates to its Amazon API Gateway API several times a week by using an AWS CodePipeline pipeline. As part of the update process, the company exports the JavaScript SDK for the API from the API Gateway console and uploads the SDK to an Amazon S3 bucket.

The company has configured an Amazon CloudFront distribution that uses the S3 bucket as an origin. Web clients then download the SDK by using the CloudFront distribution's endpoint. A DevOps engineer needs to implement a solution to make the new SDK available automatically during new API deployments.

Which solution will meet these requirements?

  • A. Create a CodePipeline action immediately after the deployment stage of the API. Configure the action to invoke an AWS Lambda function. Configure the Lambda function to download the SDK from API Gateway, upload the SDK to the S3 bucket, and create a CloudFront invalidation for the SDK path.
  • B. Create a CodePipeline action immediately after the deployment stage of the API. Configure the action to use the CodePipeline integration with API Gateway to export the SDK to Amazon S3. Create another action that uses the CodePipeline integration with Amazon S3 to invalidate the cache for the SDK path.
  • C. Create an Amazon EventBridge (Amazon CloudWatch Events) rule that reacts to UpdateStage events from aws.apigateway. Configure the rule to invoke an AWS Lambda function to download the SDK from API Gateway, upload the SDK to the S3 bucket, and call the CloudFront API to create an invalidation for the SDK path.
  • D. Create an Amazon EventBridge (Amazon CloudWatch Events) rule that reacts to CreateDeployment events from aws.apigateway. Configure the rule to invoke an AWS Lambda function to download the SDK from API Gateway, upload the SDK to the S3 bucket, and call the S3 API to invalidate the cache for the SDK path.

CodePipeline is better than Lambda function.

Although A will meet the requirements, C will as well. So why would I select A over C? Only because all required steps are carried as part of the CodePipeline workflow. With C, the Pipeline execution completes without knowing whether or not the Lambda function invoked via CloudWatch event rule is going to successfully complete or not.

This solution would allow the company to automate the process of updating the SDK and making it available to web clients. By adding a CodePipeline action immediately after the deployment stage of the API, the Lambda function will be invoked automatically each time the API is updated. The Lambda function should be able to download the new SDK from API Gateway, upload it to the S3 bucket and also create a CloudFront invalidation for the SDK path so that the latest version of the SDK is available for the web clients. This is the most straight forward solution and it will meet the requirements.
