An application in the network is being scaled up from 300 servers to 600. Each server requires 3 network connections to support production, backup, and management traffic. Each connection resides on a different subnet. The router configuration for the production network must be configured first using a subnet in the 10.0.0.0/8 network. Which command must be configured on the interface of the router to accommodate the requirements and limit wasted IP address space?

A. ip address 10.10.10.1 255.255.254.0
B. ip address 10.10.10.1 255.255.252.0
C. ip address 10.10.10.1 255.255.240.0
D. ip address 10.10.10.1 255.255.255.240

Which SDN plane forwards user-generated traffic?

A. Management plane
B. Control plane
C. Policy plane
D. Data plane
