CCNP Practice Question: Which three statements about model-driven…
Which three statements about model-driven telemetry are true? (Choose three.)
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
✓
Model-driven telemetry uses YANG data models to define the data to be streamed.
Model-driven telemetry uses YANG data models and can push data via gRPC or gNMI. It supports both periodic and on-change subscriptions. It reduces polling overhead compared to SNMP. It does not require SSH for transport (gRPC uses HTTP/2).
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Model-driven telemetry uses YANG data models to define the data to be streamed.
Why this is correct
Correct because YANG models describe the structure and semantics of the data, enabling structured telemetry.
- ✓
Telemetry data can be pushed from the network device to a collector using gRPC or gNMI.
Why this is correct
Correct because gRPC and gNMI are common transport protocols for model-driven telemetry, supporting push-based streaming.
- ✓
Model-driven telemetry supports both periodic and on-change subscriptions.
Why this is correct
Correct because subscriptions can be configured to report data at fixed intervals or only when a value changes.
- ✗
Model-driven telemetry requires SSH for secure data transport.
Why it's wrong here
Incorrect because gRPC uses TLS for encryption, not SSH; SSH is used for CLI access, not telemetry transport.
- ✗
Model-driven telemetry increases the polling overhead compared to SNMP.
Why it's wrong here
Incorrect because telemetry is push-based, reducing the need for repeated polling and thus lowering overhead.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. Which three statements about model-driven telemetry are true? (Choose three.)
hard- A.Model-driven telemetry uses a pull model where the collector requests data from network devices.
- ✓ B.Telemetry subscriptions can be configured to report data on a periodic interval or when a value changes.
- ✓ C.gRPC and gNMI are common transport protocols used for model-driven telemetry.
- D.Model-driven telemetry requires the use of SNMP for data encoding.
- ✓ E.YANG data models define the structure and semantics of telemetry data.
Why B: Model-driven telemetry (MDT) uses YANG data models and supports both periodic and on-change subscriptions. It uses a push model, reducing polling overhead. gRPC and gNMI are common transport protocols. Telemetry data can be encoded in JSON or GPB.
