* There is no downtime when new container images are deployed.

* New production releases are tested and verified using a subset of production users.

What should you do?

A.
1 Configure your Cl/CD pipeline to update the Deployment manifest file by replacing the container version with the latest version. 2 Recreate the Pods in your cluster by applying the Deployment manifest file. 3 Validate the application's performance by comparing its functionality with the previous release version and roll back if an issue arises.
