Topic #: 1

[All AWS Certified DevOps Engineer - Professional DOP-C02 Questions]

A DevOps engineer is building a multistage pipeline with AWS CodePipeline to build, verify, stage, test, and deploy an application. A manual approval stage is required between the test stage and the deploy stage. The development team uses a custom chat tool with webhook support that requires near-real-time notifications.
How should the DevOps engineer configure status updates for pipeline activity and approval requests to post to the chat tool?

A. Create an Amazon CloudWatch Logs subscription that filters on CodePipeline Pipeline Execution State Change. Publish subscription events to an Amazon Simple Notification Service (Amazon SNS) topic. Subscribe the chat webhook URL to the SNS topic, and complete the subscription validation.
B. Create an AWS Lambda function that is invoked by AWS CloudTrail events. When a CodePipeline Pipeline Execution State Change event is detected, send the event details to the chat webhook URL.
C. Create an Amazon EventBridge rule that filters on CodePipeline Pipeline Execution State Change. Publish the events to an Amazon Simple Notification Service (Amazon SNS) topic. Create an AWS Lambda function that sends event details to the chat webhook URL. Subscribe the function to the SNS topic.
D. Modify the pipeline code to send the event details to the chat webhook URL at the end of each stage. Parameterize the URL so that each pipeline can send to a different URL based on the pipeline environment.

Selected Answer: C

The DevOps engineer should configure status updates for pipeline activity and approval requests to post to the chat tool by creating an Amazon EventBridge rule that filters on CodePipeline Pipeline Execution State Change. The events should be published to an Amazon Simple Notification Service (Amazon SNS) topic, and an AWS Lambda function should be created to send event details to the chat webhook URL. The function should be subscribed to the SNS topic. Option C is the correct answer. Option A is incorrect because it suggests using CloudWatch Logs instead of EventBridge, which is not the optimal solution for this use case. Option B is incorrect because it suggests using CloudTrail instead of CodePipeline events, which is not relevant. Option D is incorrect because modifying the pipeline code is not necessary and adds unnecessary complexity.

Selected Answer: C

API calls related to AWS CodePipeline are logged by CloudTrail. However, changes to the execution state of CodePipeline are events, not API calls. These events can be captured via Amazon EventBridge.

C is correct: Use lambda to send event detail to the chat webhook url. Subcribe lambda to SNS topic A: Log subscription filer is for logging, not event B: Should not use lamda with cloudtrail events D: no need to modify pipeline code to send event at the end of each stage
