Exam 200-301 topic 1 question 1001 discussion

Answers are correct!

Answer: + supports automation + communicates between the SDN controller and the application plane + supports network virtualization protocols + supports REST-based requirements

1. **Supports Automation** - Northbound APIs typically allow for automation by enabling high-level management tools to communicate with the network, instructing the SDN controller on desired behaviors without manual intervention. 2. **Communicates between the SDN controller and the application plane** - This is one of the fundamental roles of northbound APIs. They act as the interface through which applications can communicate their requirements and objectives to the SDN controller. 3. **Supports REST-based requirements** - Northbound APIs often support REST-based interactions, making it easier for web-based applications to interact with the SDN controller using standard HTTP methods. 4. **Supports data sharing between systems** - Northbound APIs can be used to share data across different systems, enhancing interoperability and allowing different applications to benefit from network data and states provided by the SDN controller.

given answers are correct supports data sharing between systems = Northbound supports network virtualization protocols = Southbound The functions of northbound API within an enterprise data center is to develop management solutions for automation and orchestration and exchange of actionable data between systems, whereas southbound works to deliver network virtualization protocols, interact with the switch fabric or integrate distributed computing network. https://www.webwerks.in/blogs/southbound-vs-northbound-sdn-what-are-differences

Southbound APIs: Focus on data sharing between the SDN controller and the network devices for configuration and control of the network infrastructure. Northbound APIs: Focus on providing a standardized interface for applications and higher-level management systems to interact with the SDN controller.
