Exam 350-701 topic 1 question 45 discussion

Don’t over think it guys, the provided answer is correct. The security application which is the (northbound) is the one who is notifying, (sending the notification to the southbound)

I go with B. For me Northbound would be to control policies and simplify the management actions. Westbound is to integrate the controller with other devices, and use inputs received from other devices.

I would go with B.

Answer is D

Northbound API: Intent-based API Southbound API: controllers -> devices

D - application is north of the controller

Answer is D: Northbound APIs --> communication between Applications and the SDN Controller Southbound APIs --> communication between Network Devices and the SDN Controller

Intent (Northbound) APIs - used to enforce the configurations and settings - creating and managing sites - retrieving network health information - policy creation - Rest APIs - Common in web services - Use HTTP requests for data transfer - GET, PUT, POST and DELETE requests Integration (Westbound) APIs: - Integrate controller with other platforms - Communicate with third-party IT service management solutions - Ticket and request automation - Publish the network data, events and notifications to the external systems Multivendor Support (Southbound) APIs: - Multivendor Software Development Kit (SDK) - SDKs can include multiple APIs - SDKs allow for management of non-Cisco devices Events and Notifications (Eastbound) APIs: - Allow external systems to take action against notifications - Especially useful for security compliance

Sorry meant Northbound APIs are typically used to communicate between the SDN controller and the services and applications running over the network. However, in the context of the question provided, a security application is notifying the controller about a specific security threat, which would be accomplished through a Southbound API. Northbound APIs are generally used for different purposes such as automation and orchestration of the network components, whereas Southbound APIs are used for communication between the controller and the underlying network devices.

How about this info? Northbound APIs (SDN northbound APIs) are typically RESTful APIs that are used to communicate between the SDN controller and the services and applications running over the network. Such northbound APIs can be used for the orchestration and automation of the network components to align with the needs of different applications via SDN network programmability. In short, northbound APIs are basically the link between the APPLICATIONS and the SDN controller.

NorthBound API for sure

Answer is D, check quick video below, https://youtu.be/BUuNgQn3uNc

Northbound APIs (SDN northbound APIs) are typically RESTful APIs that are used to communicate between the SDN controller and the services and applications running over the network. Such northbound APIs can be used for the orchestration and automation of the network components to align with the needs of different applications via SDN network programmability. In short, northbound APIs are basically the link between the applications and the SDN controller. In modern environments, applications can tell the network devices (physical or virtual) what type of resources they need and, in turn, the SDN solution can provide the necessary resources to the application. From the Cisco OCG. Answer is D since the question talks about a security application

Answer should be B , the difference between Northbound and Westbound API interfaces is very clear from the bellow link : https://blogs.cisco.com/networking/with-apis-cisco-dna-center-can-improve-your-competitive-advantage

Westbound should be right: Northbound - intent-based management user to controller Southbound - Controller to network elements Eastbound - Controller to other Applications Westbound - Other software to Controller https://developer.cisco.com/docs/dna-center/#!cisco-dna-center-platform-overview/intent-api-northbound
