Which tool shows how much of a capacity is being used?
Why B is the answer
The Microsoft Fabric Capacity Metrics app
Microsoft describes the app for monitoring capacity usage, measured in capacity units.
In detail
- The Capacity Metrics app shows capacity use.
- Use it before you buy a larger capacity.
Use case
An illustrative scenario, not a real incident.
Reports slow down each afternoon. The Capacity Metrics app shows capacity unit use peaking then, and which items drive it.

Key point: The Capacity Metrics app shows capacity use.
Why the other options are wrong
- A. The OneLake file explorer
- That shows files.
- C. A Spark notebook's first cell
- A notebook cell does not report capacity.
- D. The deployment pipeline history
- That history shows deployments.
