A CodePipeline execution is failing because the source action cannot access the source repository. What is the most likely cause?

The build stage is not configured correctly

The pipeline does not have any stages

The deploy stage is not configured correctly

The source action is not configured with the correct credentials or permissions

In AWS CodeDeploy, what is the purpose of lifecycle event hooks?

To run scripts at specific points during the deployment process

To store the application revision to be deployed

To specify the target instances for the deployment

To define the deployment strategy (e.g., canary, linear)

In a CI/CD pipeline, what typically happens if a unit test fails during the build stage?

The pipeline automatically fixes the code and reruns the test

The pipeline continues to the next stage but logs a warning

The pipeline stops and the deployment is blocked

The pipeline skips the test and proceeds to deployment

What is the purpose of a rollback procedure in an ML model deployment?

To delete the model from production if it is no longer needed

To automatically retrain the model if its performance degrades over time

To update the model's training data to improve its accuracy

To revert to a previous version of the model if the new version performs poorly or causes issues
