300-420 Question 291
Single answerA network engineer is tasked with implementing a network automation solution that uses standardized and vendor-neutral models to enhance interoperability across devices from multiple vendors. Which YANG model should the engineer prioritize for this requirement?
- A
IETF YANG models
- B
OpenConfig YANG models
- C
Cisco native YANG models
- D
Proprietary vendor-specific YANG models
Show answer and explanation
Correct answer: A
Explanation
The IETF YANG models are developed to provide a standardized and vendor-neutral approach for network management and automation. This makes them the most suitable choice for environments that require interoperability across multiple vendors, aligning with the scenario described.
- A. Correct.
IETF YANG models are standardized and vendor-neutral, making them suitable for interoperability across devices from multiple vendors. They are developed by the Internet Engineering Task Force (IETF) and aim to provide a common framework for network management.
- B. Incorrect.
OpenConfig YANG models, while vendor-neutral, are typically focused on specific use cases and driven by network operators for operational consistency. They are not as broadly standardized as IETF models.
- C. Incorrect.
Cisco native YANG models are specific to Cisco devices and are not vendor-neutral, which limits interoperability in multi-vendor environments.
- D. Incorrect.
Proprietary vendor-specific YANG models are tailored to individual vendors and do not prioritize standardization or interoperability across devices from different vendors.
