Good catch on the storage size, but it’s fine for testing!

I thought we could use ReadWriteMany for this?

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

Just a reminder, the PVC name should match in both files!

I definitely need to double-check the command for expanding the PersistentVolumeClaim. I think it’s `kubectl edit`, but I’m not 100% sure about the flags.

I’m a bit confused about the access modes. I know it’s ReadWriteOnce, but I hope I don’t mix it up with ReadOnlyMany.

This question seems similar to the practice ones we did last week, especially the part about mounting the volume in the Pod.

I think I remember how to create a PersistentVolumeClaim, but I'm not entirely sure about the exact syntax for the YAML file.

Wait, do I need to use kubectl patch instead of kubectl edit to expand the PVC capacity? I want to make sure I record the change properly.

Okay, this looks straightforward enough. I'll just follow the steps in the question and use the provided information to create the necessary resources.

Hmm, I'm a bit unsure about the exact YAML syntax for the PVC and Pod. I'll need to review the example closely and make sure I get the details right.

I think I've got a good handle on this. I'll start by creating the PersistentVolumeClaim YAML file, then the Pod YAML file, and finally use kubectl edit to expand the PVC capacity.

Hmm, I'm a bit unsure about this one. Creating the DHCP server profile first seems logical, but I'm not sure if that's the right approach here. Let me re-read the question and options.

Okay, I think I've got it. The Max Target sets the desired RAID level for the primary data volume, while the Min Target sets the desired RAID level for the associated mirror and snapshot volumes. That makes sense in terms of the data protection requirements.

I'm a bit confused here. I thought services could enter various roles depending on the context. Maybe I misinterpreted the examples we covered.
