SDN and IoT Concepts Quiz

Which layer is responsible for centralized control in SDN architecture?

• Application Layer

• Infrastructure Layer

• Control Layer

• Data Plane

What is the primary function of NFV in a networked IoT system?

• Encrypting data at rest

• Centralizing control of data flows

• Virtualizing network services

• Monitoring bandwidth usage

What is a key difference between SDN and NFV?

• SDN uses more hardware than NFV

• NFV focuses on virtualizing functions, SDN on control logic

• NFV is used only in LANs, SDN in WANs

• SDN operates only at the application layer
