A development team wants to immediately build and deploy an application whenever there is a change to the source code. Which approaches could be used to trigger the deployment? (Choose two.)

Amazon S3 can be configured as a CodePipeline source stage. When a new object version is uploaded to the bucket, an Amazon EventBridge rule detects the change and triggers the pipeline automatically, enabling event-driven CI/CD.

Amazon EBS volumes are block storage devices attached to EC2 instances and are not supported as a CodePipeline source; there is no mechanism to trigger a pipeline on EBS content changes.

AWS CodeCommit is a native CodePipeline source provider. CodePipeline listens for push events to the specified branch via EventBridge and starts the pipeline immediately when new code is committed, with no polling delay.

Polling S3 every 15 minutes does not fulfill the requirement of deploying immediately on every source change; it introduces up to a 15-minute delay and is not event-driven.

EC2 instance ephemeral storage is local, temporary disk space that is not accessible outside the instance and cannot be used as a CodePipeline source trigger.
