Question
What is an advantage of using model-driven telemetry in the network?
Options
- AIt uses interrupt-driven polling to pull data at regular intervals.
- BIt uses MIB models to structure the data that are well known in the industry.
- CIt uses JSON encoding and is compatible with a wide variety of tools on the market.
- DTelemetry obtains data by parsing the CLI output from show commands.
Explanation
An advantage of model-driven telemetry in networks is its use of standardized data models and encoding formats like JSON, which ensures compatibility with a broad range of monitoring and analysis tools.
Common mistakes.
- A. Model-driven telemetry typically uses a push-based model (subscription-based streaming) rather than traditional pull-based polling, which makes it more efficient and provides near real-time data.
- B. While MIBs (Management Information Bases) are well-known, model-driven telemetry primarily uses YANG data models, which offer more robust capabilities for defining configuration and state data than SMI-based MIBs.
- D. Traditional methods often rely on parsing unstructured CLI output, which is fragile and error-prone; model-driven telemetry avoids this by streaming structured data directly from the device's internal data models.
