Which statements regarding network devices operational planes are true?

The data plane is responsible for the actual transmission of data packets through the network device. This operational plane is focused on forwarding incoming data (ingress) to the correct outgoing interface (egress). It performs functions such as switching, routing, and applying access control lists, all of which are critical for maintaining the flow of traffic within a network. The data plane operates at the fundamental level of connectivity, ensuring that data reaches its destination efficiently.

Understanding the roles of the other planes provides context for why they do not match the characteristics of the data plane. The control plane primarily deals with protocols and decisions regarding the network configuration and routing, while the management plane focuses on the overall management and monitoring of devices, which includes settings and administrative tasks. Therefore, stating that the data plane moves data from ingress to egress captures the essential function of this operational plane accurately, highlighting its primary purpose in the network architecture.
