300-420 Question 76
Select 3An enterprise network engineer is tasked with implementing platform abstraction within a multi-vendor network environment to improve automation, scalability, and consistency. Which of the following techniques would best achieve this goal?
- A
Using APIs to interact with network devices regardless of vendor-specific configurations
- B
Adopting an SDN controller to centralize network management and abstract hardware details
- C
Manually standardizing CLI configurations across all devices in the network
- D
Leveraging YANG models to define device configurations in a vendor-neutral manner
- E
Using proprietary network management tools provided by each vendor
Show answer and explanation
Correct answers: A, B, D
Explanation
Platform abstraction techniques aim to decouple network management and automation from vendor-specific dependencies. APIs, SDN controllers, and YANG models are key enablers of abstraction, allowing engineers to build scalable and interoperable networks. In contrast, manual CLI standardization and proprietary tools lack scalability and fail to provide true abstraction in multi-vendor environments.
- A. Correct.
Correct: APIs provide a programmatic way to interact with devices, abstracting underlying vendor-specific details and enabling automation.
- B. Correct.
Correct: An SDN controller abstracts the hardware layer, providing centralized management and programmable network capabilities, which simplifies multi-vendor environments.
- C. Incorrect.
Incorrect: Manually standardizing CLI configurations is not scalable and does not constitute abstraction, as it still depends on vendor-specific syntax.
- D. Correct.
Correct: YANG models are a platform-agnostic way to define configurations, enabling automation and abstraction across different vendors.
- E. Incorrect.
Incorrect: Proprietary tools are vendor-specific and do not provide abstraction across a multi-vendor environment.
