300-435 Question 54
Single answerA network engineer is tasked with implementing programmability across their multi-vendor network infrastructure. They require a solution that provides vendor-neutral data models to simplify management across various devices while also adhering to industry standards. Which of the following YANG models would be the most suitable for this use case?
- A
OpenConfig
- B
IETF YANG
- C
Native YANG
- D
Proprietary CLI-based models
Show answer and explanation
Correct answer: A
Explanation
OpenConfig is the most suitable YANG model for managing multi-vendor environments because it is vendor-neutral and designed to simplify operational consistency across diverse devices. While IETF YANG models are also standardized, they may not address all operational use cases as comprehensively. Native YANG models are specific to individual vendors, and CLI-based models do not align with modern programmability requirements.
- A. Correct.
OpenConfig is a vendor-neutral YANG model that focuses on multi-vendor operability and is ideal for simplifying network management across diverse infrastructures. It is specifically designed to address the use case described.
- B. Incorrect.
IETF YANG models are standardized and widely adopted, but they may not always cover all operational use cases in multi-vendor environments as comprehensively as OpenConfig. They are more generic and focused on industry-wide standards.
- C. Incorrect.
Native YANG models are vendor-specific, making them unsuitable for managing a multi-vendor network infrastructure. They are tailored to the features of a specific vendor's devices.
- D. Incorrect.
Proprietary CLI-based models are not YANG models and do not provide programmability or vendor-neutral capabilities. They are outdated for modern network programmability.
