You manage a CustomResourceDefinition (CRD) for "Widgets". Currently, the API allows users to create widgets with missing or invalid configuration, which causes the controller to crash.

A CronJob named cleanup in the ops namespace is failing to trigger as expected. It has an incorrect schedule, relies on the default timezone (which may not match the server), and retains too many completed jobs, cluttering the history.

A Job manifest at /home/interview/fail-job.yaml is failing with a non-zero exit status. The Job has limited retries configured.

Log rotation has stopped working correctly, and you suspect that /var/log might be mounted on a different filesystem with limited space or incorrect mount options.

During peak traffic hours, a background data-processing job that is started by user devops is consuming too much CPU and slowing down user-facing services. Stopping it isn't an option because it would interrupt ongoing workflows, but you need to limit its CPU usage temporarily.

The server has unmounted partitions that are not being used and could be utilized for additional storage.
