350-501 Automation and Assurance Practice Question
What is the primary benefit of using model-driven telemetry over traditional SNMP polling for network assurance?
⚠ Common exam trap
Cisco often tests the misconception that model-driven telemetry is primarily about security or simplicity, when the core differentiator is the shift from pull-based (SNMP) to push-based (telemetry) data collection for real-time, low-overhead streaming.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Provides real-time data streaming without polling overhead
Model-driven telemetry uses a push model where network devices continuously stream structured data (e.g., YANG-encoded) to a collector, eliminating the need for periodic SNMP polling. This provides real-time visibility with minimal CPU overhead on the device, as the device itself initiates the data export based on configured subscriptions, rather than responding to repeated GET requests.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Provides real-time data streaming without polling overhead
Why this is correct
Push-based telemetry eliminates polling.
- ✗
Reduces the need for YANG models
Why it's wrong here
Telemetry actually uses YANG models.
- ✗
Increases security by using SSH
Why it's wrong here
Both can use secure transports.
- ✗
Simplifies device configuration
Why it's wrong here
Telemetry configuration can be complex.
