Exam 400-007 topic 1 question 169 discussion

By using the East-West API, tasks can be distributed and executed on any controller within the cluster, providing flexibility and scalability in managing the network. This standardized interface ensures interoperability and allows for the seamless coordination of network policies and configurations across different controllers in a multisite deployment. Options A, C, and D are not directly related to the ability to run tasks on any controller via a standardized interface. Building direct physical connectivity between controllers (option A) may improve communication but doesn't necessarily address task execution. OpenFlow (option C) is a protocol used for controlling the forwarding plane of network devices, while deploying a root controller (option D) focuses on gathering network-level information but does not specifically address the execution of tasks on any controller. Therefore, option B is the most appropriate requirement for addressing the ability to run tasks on any controller via a standardized interface in a multicontroller SDN solution.

'C' - https://www.hindawi.com/journals/jcnc/2016/9396525/

B is the ans. The East-West API is used to facilitate communication between controllers within a cluster, allowing them to exchange information and synchronize their states.
