An administrator receives analert in Prismstating:"Storage container on cluster will run out of storage resources...

Reserved Capacity settings define how much storage is exclusively allocated for a specific container.

Option B (Reserved Capacity is too high) is correct:

If too much space is reserved for a container, it can report "out of space" while the cluster still has free capacity.

Options A, C, and D are incorrect:

Advertised Capacity, Compression, and RF settings do not directly cause storage exhaustion unless misconfigured with Reserved Capacity.
