Which of the following devices exist as either hardware or software to assist in routing traffic? (Select TWO).

A cable modem connects a local network to the ISP's cable infrastructure and is a fixed-function hardware device that does not perform internal network routing.

A Layer 2 switch forwards frames based on MAC addresses within a single broadcast domain and does not perform IP routing between networks.

Routers are dedicated devices that forward packets between networks using routing protocols and exist as physical hardware appliances or software-based virtual routers (e.g., VyOS, Cisco CSR). Layer 3 switches combine traditional Layer 2 switching with IP routing capability and also exist as both physical hardware and virtual appliances, allowing them to route traffic between VLANs and subnets in addition to performing switching functions.

A NIDS (Network Intrusion Detection System) is a passive monitoring device that analyzes traffic for threats and does not route or forward packets.

Layer 3 switches combine traditional Layer 2 switching with IP routing capability and also exist as both physical hardware and virtual appliances, allowing them to route traffic between VLANs and subnets.
