Wait, why only 10Mi? Seems a bit small for a web server.

I feel confident about creating the PVC, but I might mix up the volume names in the Pod definition. Need to double-check that!

I'm a bit unsure about the exact syntax for the kubectl edit command. Did we need to specify anything else besides the PVC name?

This question seems similar to the practice we did on volume mounts. I hope I can recall the access modes correctly during the exam.
