Issue description

In the solutions for exercise on RBAC, quotas, and limit ranges, the following files are named incorrectly in the solutions directory:

• pvc-test-1.yaml (pvc-test1.yaml)
• pvc-test-2.yaml (pvc-test2.yaml)

The file pvc-limitrange.yaml is out of sync with the requirements of the exercise as it sets spec.limits.max.storage to 10Gi instead of 15Gi.
