14
What is the main purpose of SDN?
To make networks slower but more stable
To eliminate the need for network security
To replace physical networking hardware with software
To improve the flexibility and control of network management
15
What is an example of an SDN application?
A router that only allows wired connections
A software firewall that blocks all traffic
A device that replaces all switches in a network
A dynamic load balancer that distributes network traffic
