Nokia Certified Associate – AI and Analytics — Question 42

Which of the following is NOT an advantage of Software-Defined Networks (SDN) over traditional networks?

Answer options

• B. Applications communicate directly with the controller
• C. An integrated control plane and data plane
• D. Greater agility in automating, monitoring, and provisioning network infrastructure

Correct answer: B

Explanation

Option B is correct because one of the advantages of SDN is that applications typically interact with the network through APIs rather than directly with the controller, which allows for more flexible and scalable interactions. Options A, C, and D all highlight significant benefits of SDN, including centralized control, integration of control and data planes, and enhanced automation and monitoring capabilities.
