What is the purpose of software-defined networking (SDN)?

• To create physical networking devices

• To virtualize networking platforms in the cloud

• To eliminate the need for data planes

• To increase the use of physical routers

Which layer of a networking device is responsible for forwarding, trunking, and encrypting traffic?

• Management layer

• Control layer

• Data plane

• Infrastructure layer

Where are dynamic routing protocols and forwarding tables typically stored in a networking device?

• Infrastructure layer

• Management plane

• Control plane

• Data plane

How do network administrators manage devices in the software-defined networking model?

• Through direct hardware manipulation

• By physically accessing the device

• Via a console port or management interface

• By using traditional physical switches

In software-defined networking, what is the purpose of the data plane?

• To forward traffic between interfaces
