Developing Applications and Automating Workflows Using Cisco Platforms (DEVASC) — Question 491

What is a difference between device-level and controller-level infrastructure management?

Answer options

• A. Device-level management uses NETCONF, whereas controller-level management does not support NETCONF to automate the infrastructure.
• B. Controller-level management uses APIs to simplify the developer experience, whereas device-level management uses traditional management protocols.
• C. Controller-level management is more widely supported because it is standards-based, whereas device-level management is proprietary to each vendor.
• D. Controller-level management exposes northbound, southbound, eastbound, and westbound APIs, easing integration with other technologies, whereas device-level management does not use a controller-based API.

Correct answer: B

Explanation

The correct answer is B because controller-level management's use of APIs significantly simplifies the development process compared to the traditional management protocols used in device-level management. The other options incorrectly describe the capabilities and characteristics of each management type, with some focusing on features that do not accurately represent the differences in management approaches.
