300-420 Question 292
Single answerYour company is implementing a network automation project and evaluating different YANG model standards. The requirement is to use a vendor-neutral data model for configuring and monitoring network devices across a multi-vendor environment, while also ensuring compatibility with open-source tools. Which YANG model should you choose?
- A
IETF YANG model
- B
OpenConfig YANG model
- C
Cisco-native YANG model
- D
SNMP MIBs
Show answer and explanation
Correct answer: B
Explanation
OpenConfig YANG models are specifically designed for multi-vendor interoperability and are developed by network operators to address gaps in standardization for advanced use cases. They align well with the requirements of a vendor-neutral network automation project and are commonly used alongside open-source tools, making them the best choice for this scenario.
- A. Incorrect.
IETF YANG models are vendor-neutral and widely adopted, but they focus more on standardizing basic network elements and may not fully support advanced, multi-vendor use cases required in this scenario.
- B. Correct.
OpenConfig YANG models are vendor-neutral and designed specifically for multi-vendor interoperability. They are developed by a consortium of network operators and are commonly used with open-source tools, making them ideal for this requirement.
- C. Incorrect.
Cisco-native YANG models are specific to Cisco devices and are not vendor-neutral. They are useful in Cisco-only environments but do not meet the multi-vendor requirement in this scenario.
- D. Incorrect.
SNMP MIBs are not YANG models. They are used in traditional network management for monitoring but lack the capabilities and flexibility provided by YANG-based models for modern network automation.
