350-401 Question #1169: Real Exam Question with Answer & Explanation

Question

What is one characteristic of Cisco DNA Center and vManage northbound APIs?

Options

• AThey push configuration changes down to devices.
• BThey exchange XML-formatted content.
• CThey implement the RESTCONF protocol.
• DThey implement the NETCONF protocol.

Explanation

Cisco DNA Center and vManage northbound APIs are primarily RESTful and for specific programmatic interactions, often implement the RESTCONF protocol.

Common mistakes.

• A. Northbound APIs are consumed by external systems to interact with the controller; the controller then uses southbound APIs to push configuration changes down to devices, so the northbound API itself does not directly push to devices.
• B. Modern Cisco DNA Center and vManage APIs primarily exchange data using JSON (JavaScript Object Notation), not XML (Extensible Markup Language), for better interoperability and efficiency.
• D. NETCONF is a protocol for managing network devices, often used for southbound communication or direct device management, while northbound APIs are typically RESTful protocols like RESTCONF for higher-level orchestration.

Concept tested. Northbound API protocols (RESTCONF)
