Haha, rolling updates and rollbacks? That's child's play! I could do this in my sleep. This exam is going to be a breeze.

Looks good! The key steps are creating the initial deployment, then updating the image to the new version, and finally rolling back to the previous version. Shouldn't be too difficult.

I believe we need to carefully manage the replicas during the update.

This deployment task seems straightforward. I'll use the `kubectl set image` command to perform the rolling update and `kubectl rollout undo` to rollback the deployment.
