350-601 Automation Practice Question
An organization is migrating from traditional SNMP monitoring to model-driven telemetry on their Nexus 9000 switches. They have configured a telemetry destination using gRPC and have defined sensor paths for interface statistics. After several hours, the collector (a Linux server running Telegraf) reports no data received. The engineer verifies that the switch can reach the collector via ICMP. On the switch, 'show telemetry data collector details' indicates the destination is 'connected', but the 'last data sent' timestamp is several hours old. Which action should the engineer take next?
⚠ Common exam trap
Cisco often tests the misconception that a 'connected' telemetry destination implies data is flowing, when in fact the connection state only reflects the gRPC session, not the subscription health—candidates may waste time on transport or connectivity fixes instead of verifying the sensor paths.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Verify that the sensor paths are correct and that the data is being generated
The 'show telemetry data collector details' output shows the destination is 'connected' and the switch can reach the collector, ruling out network or connectivity issues. The stale 'last data sent' timestamp indicates the telemetry process is running but no data is being published, which typically means the configured sensor paths are not producing data—either because the paths are incorrect, the MIB objects are not supported, or the interfaces are not generating the expected statistics. Option C is correct because verifying the sensor paths and ensuring data generation addresses the root cause without unnecessary changes or reboots.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Change the transport protocol from gRPC to HTTP
Why it's wrong here
Would not fix missing data; might break other functionality.
- ✗
Reboot the switch to reset the telemetry process
Why it's wrong here
Unnecessary; the process is running.
- ✓
Verify that the sensor paths are correct and that the data is being generated
Why this is correct
Most likely cause: sensor path not matching actual data.
- ✗
Increase the telemetry sampling interval to reduce load
Why it's wrong here
Does not address why data is not sent at all.
