A company configured an EventBridge custom event pattern to be notified when CodePipeline execution states fail. Which type of events will match that pattern?

The correct answer is "All rejected or failed approval actions across all the pipelines." CodePipeline execution state changes, specifically those related to approval actions, generate events that EventBridge can capture. When an approval action is rejected or fails, it triggers a specific event pattern. This allows the company to be notified precisely when a manual approval step in any pipeline is not successfully completed, indicating a potential blockage or issue in the deployment process. "Failed deploy and build actions across all the pipelines" is incorrect because while these actions also generate events, the question specifically refers to "execution states fail," which is a broader category that includes approval actions, and the most direct match for "failed" in the context of approval is "rejected or failed approval." "All the events across all pipelines" is too broad and would not match a specific pattern for failed execution states. "Approval actions across all the pipelines" is too general; it would include successful approvals, not just failed ones, and thus wouldn't match the "execution states fail" condition.
