CCDE: Cisco Certified Design Expert (Practical) — Question 95

An enterprise solution team is performing an analysis of multilayer architecture and multicontroller SDN solutions for multisite deployments. The analysis focuses on the ability to run tasks on any controller via a standardized interface. Which requirement addresses this ability on a multicontroller platform?

Answer options

• A. Build direct physical connectivity between different controllers
• B. Use the East-West API to facilitate replication between controllers within a cluster
• C. Use OpenFlow to implement and adapt new protocols
• D. Deploy a root controller to gather a complete network-level view

Correct answer: B

Explanation

The correct answer is B, as the East-West API allows for the replication and communication between controllers within the same cluster, ensuring tasks can be executed seamlessly across them. Option A is incorrect because direct physical connectivity does not address the need for a standardized interface. Option C pertains to protocol implementation rather than the specific task execution capability, and D focuses on network visibility rather than task execution across controllers.
