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
