Why each option
A router is a network device specifically designed to forward traffic between different networks, such as from an internal private network to an external public network like the internet.
A hub is a Layer 1 device that simply broadcasts all incoming traffic to all other ports within the same network segment and cannot route between different networks.
A router operates at Layer 3 (Network Layer) of the OSI model and is responsible for routing traffic between different IP networks, making it the device that forwards traffic from internal private IP addresses to external public IP addresses, often performing Network Address Translation (NAT) in the process.
A CNA (Converged Network Adapter) is a type of network interface card that supports both Ethernet and Fibre Channel over Ethernet, but it does not perform routing between internal and external IP addresses.
A NIC (Network Interface Card) is a hardware component that allows a computer to connect to a network, but it does not route traffic between different IP networks.
