Explanation

NIC vendor OUI -> 00:0C:22NIC MAC address -> 00:0C:22:83:79:A3default gateway -> 192.168.1.193host IP address -> 192.168.1.200subnet mask -> 255.255.255.192 The "ip route" and "ip addr show eth1" are Linux commands.+ "ip route": display the routing table+ "ip addr show eth1": get depth information (only on eth1 interface) about your network interfaces like IP Address, MAC Address information

Most traditional devices use a distributed architecture, in which each control plane is resided in a networking device. Therefore they need to communicate with each other via messages to work correctly.
In contrast to distributed architecture, centralized (or controller-based) architectures centralizes the control of networking devices into one device, called SDN controller -> Answer D is correct.
