Certificate of Cloud Security Knowledge (CCSK) — Question 122

What is a method used to decouple the network control plane from the data plane?

Answer options

• A. Information Management Policies
• B. Multitenancy
• C. Network Intrusion Detect on Systems (NIDS)
• D. Software Defined Networking (SDN)
• E. Virtual LANs (VLANs)

Correct answer: D

Explanation

Software Defined Networking (SDN) is the correct answer because it allows for the separation of the control plane and data plane, enabling more flexible and efficient network management. The other options do not provide this decoupling; for example, Information Management Policies and Multitenancy focus on policy management and resource allocation rather than the control and data plane separation.
