Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) — Question 274

How does model-driven telemetry use YANG?

Answer options

• A. to poll network devices on a 30-minute interval
• B. to set informs and traps on clients to report back to a centralized server
• C. to subscribe to data that is streamed from a device
• D. to reset network devices that malfunction

Correct answer: C

Explanation

The correct answer is C because model-driven telemetry leverages YANG to enable subscriptions for real-time data streaming from devices. Options A and B describe polling and reporting mechanisms that are not specific to YANG's capabilities, while option D refers to device management rather than telemetry.
