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
✓
Telemetry subscriptions can be configured to report data on a periodic interval or when a value changes.
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.
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 a pull model where the collector requests data from network devices.
Why it's wrong here
MDT is a push model; devices send data to collectors based on subscriptions.
- ✓
Telemetry subscriptions can be configured to report data on a periodic interval or when a value changes.
Why this is correct
Subscriptions support both periodic (cadence-based) and on-change reporting.
- ✓
gRPC and gNMI are common transport protocols used for model-driven telemetry.
Why this is correct
gRPC (often with gNMI) is a standard way to stream telemetry data from Cisco devices.
- ✗
Model-driven telemetry requires the use of SNMP for data encoding.
Why it's wrong here
MDT typically uses JSON, GPB (Google Protocol Buffers), or XML, not SNMP.
- ✓
YANG data models define the structure and semantics of telemetry data.
Why this is correct
YANG models are used to describe the data that can be streamed via telemetry.
