400-007 Question #433: Real Exam Question with Answer & Explanation
The correct answer is A: programmable forwarding pipelines. In-Band Network Telemetry (INT) differs from conventional monitoring by embedding telemetry instructions into packet headers, which requires programmable forwarding pipelines in network devices to process and carry the telemetry data in real time.
Question
In the In-Band Network Telemetry (INT) approach, telemetry instructions are encoded into packet header fields and then processed by network switches as they flow. Which element makes INT different from the conventional monitoring?
Options
- Aprogrammable forwarding pipelines
- Bcollective network state
- Csampling subsets of packets
- Dfixed counters reading
Explanation
In-Band Network Telemetry (INT) differs from conventional monitoring by embedding telemetry instructions into packet headers, which requires programmable forwarding pipelines in network devices to process and carry the telemetry data in real time.
