300-435 Question 55
Select 3An enterprise network engineer is tasked with automating the configuration of network devices across a multi-vendor environment. The engineer needs a solution that provides vendor-neutral configuration models while also being able to support specific vendor features when necessary. Which combination of YANG models would best meet these requirements?
- A
OpenConfig YANG models for vendor-neutral configurations
- B
IETF YANG models for industry-standard and protocol-based configurations
- C
Native YANG models for vendor-specific feature support
- D
Only OpenConfig YANG models for all configurations
- E
Only IETF YANG models to standardize all configurations
Show answer and explanation
Correct answers: A, B, C
Explanation
To automate configurations in a multi-vendor environment, a combination of OpenConfig, IETF, and native YANG models is ideal. OpenConfig provides vendor-neutral models for consistent configurations across platforms, IETF models ensure adherence to standardized protocols, and native YANG models allow for vendor-specific feature implementation. This combination ensures flexibility, compatibility, and comprehensive network automation.
- A. Correct.
OpenConfig YANG models are vendor-neutral and are ideal for multi-vendor environments, making them suitable for standardized configurations across different platforms.
- B. Correct.
IETF YANG models are based on industry standards and protocols, which can complement OpenConfig for general network automation tasks.
- C. Correct.
Native YANG models are specific to individual vendors, allowing the engineer to configure features that are not covered by OpenConfig or IETF models.
- D. Incorrect.
Using only OpenConfig YANG models would limit the ability to support vendor-specific features, which may be necessary in a multi-vendor environment.
- E. Incorrect.
Using only IETF YANG models would not cover vendor-specific features or provide the flexibility of vendor-neutral configurations like OpenConfig.
