What adds finer visibility than interface counters?
Why B is the answer
In-band telemetry
Telemetry shows behavior along the packet's path.
In detail
- Telemetry shows behavior along the packet's path.
- It shows the packet's path.
Use case
An illustrative scenario, not a real incident.
Counters look fine, but in-band telemetry shows delay on one hop.

Why the other options are wrong
- A. A longer SNMP polling interval
- Polling less often gives less detail.
- C. A longer log retention period
- Keeping logs longer adds no detail.
- D. A longer SSH timeout
- A session timeout adds no detail.
