300-435 Question 58
Select 3A network engineer is tasked with automating the configuration of a multi-vendor network environment. The solution must provide vendor-neutral configuration models, while ensuring compatibility with legacy devices using native models. Which YANG model(s) should the engineer consider using to meet these requirements?
- A
OpenConfig YANG models
- B
IETF YANG models
- C
Native YANG models
- D
SNMP MIB models
- E
NETCONF RPC YANG models
Show answer and explanation
Correct answers: A, B, C
Explanation
When automating a multi-vendor network, OpenConfig YANG models are ideal for achieving vendor-neutral configuration, while IETF YANG models ensure broad compatibility and standardization. Native YANG models are required for legacy devices or vendor-specific features. Combining these models allows for flexibility and seamless operation in diverse environments.
- A. Correct.
OpenConfig YANG models provide vendor-neutral, standardized models that are beneficial in multi-vendor environments.
- B. Correct.
IETF YANG models are standardized and widely supported, making them suitable for both vendor-neutral implementations and legacy compatibility.
- C. Correct.
Native YANG models are vendor-specific and are necessary for interfacing with legacy devices or when features unique to a vendor are required.
- D. Incorrect.
SNMP MIB models are not based on YANG and are not relevant in this context; they are used for SNMP-based monitoring and management.
- E. Incorrect.
NETCONF RPC YANG models are not a specific type of YANG model. NETCONF is a protocol used to interact with YANG models but is not itself a YANG model.
