Designing Cisco Enterprise Networks (ENSLD) — Question 108

A company must automate a set of complex changes aligned with DR testing in the network. These changes are specific, and the DR playbook will be adjusted in the future. The playbook has diverse routing and switching assets in scope as well as multiple vendor and hardware platforms. A developer will create a thin, web front-end microservice and integrate with an Open Daylight controller to push changes to the network. Which YANG model should be used?

Answer options

• A. Use an open YANG model to allow the reuse of code and standardize the implementation across platforms.
• B. Develop an individualized YANG model to minimize development resources and time to market.
• C. Use multiple native vendor YANG models to provide code consistency.
• D. Use a single native vendor YANG model to minimize development time.

Correct answer: A

Explanation

The correct answer is A because using an open YANG model promotes code reuse and helps standardize the approach across various platforms, which is essential given the diversity of assets. Options B, C, and D do not support the need for standardization and may lead to inconsistencies and increased complexity when integrating with multiple vendor systems.
