An eventstream falls behind under high volume. What should you review first?
Why B is the answer
Throughput settings and processing at the destination
High volume exposes the slowest step, so review the throughput settings and how fast the destination processes events.
In detail
- Check throughput settings first, then processing at the destination.
- A stream moves only as fast as its slowest step.
Use case
An illustrative scenario, not a real incident.
An eventstream falls behind at peak. The destination is the bottleneck, so reviewing throughput and processing there fixes it.

Key point: Check throughput and the destination.
Why the other options are wrong
- A. The semantic model's storage mode
- A storage mode has no effect on an eventstream.
- C. The sensitivity label on the workspace
- A label has no effect on throughput.
- D. The deployment pipeline stage
- A deployment stage has no effect.
