300-435 · Question #43

Which statement describe the difference between OpenConfig and native YANG data models?

The correct answer is D. Native models are developed by vendors and designed to integrate to features or configurations that are relevant only to that platform. OpenConfig models are designed for vendor-neutrality and interoperability across multiple platforms, while native YANG models are proprietary, developed by vendors to expose platform-specific features.

Question

Which statement describe the difference between OpenConfig and native YANG data models?

Options

  • ANative models are designed to be independent of the underlying platform and are developed by vendors and standards bodies, such as the IETF.
  • BNative models are developed by individual developers and designed to apply configurations on platforms.
  • COpenConfig models are developed by vendors and designed to integrate to features or configurations that are relevant only to that platform.
  • DNative models are developed by vendors and designed to integrate to features or configurations that are relevant only to that platform.

Why each option

OpenConfig models are designed for vendor-neutrality and interoperability across multiple platforms, while native YANG models are proprietary, developed by vendors to expose platform-specific features.

ANative models are designed to be independent of the underlying platform and are developed by vendors and standards bodies, such as the IETF.

This statement describes OpenConfig models, which are designed to be vendor-agnostic and are developed by the OpenConfig working group, not primarily by IETF or individual vendors for native models.

BNative models are developed by individual developers and designed to apply configurations on platforms.

While native models are used to apply configurations, they are primarily developed by vendors for their specific platforms, not typically by individual developers as a defining characteristic against OpenConfig.

COpenConfig models are developed by vendors and designed to integrate to features or configurations that are relevant only to that platform.

This statement incorrectly attributes the characteristics of *native* vendor-specific models to OpenConfig models, which are explicitly designed for vendor-neutrality.

DNative models are developed by vendors and designed to integrate to features or configurations that are relevant only to that platform.Correct

Native YANG models are developed by individual network equipment vendors to expose their unique, platform-specific features and configurations, making them proprietary and inherently tied to a particular vendor's implementation.
