Each floor of an office building is configured as a separate IP subnet to reduce broadcast traffic. Employees on the 3rd-floor subnet must communicate with resources on the 4th-floor subnet. Which of the following devices should you deploy to enable traffic between the two different IP networks?
A router is a Layer 3 device that examines destination IP addresses and forwards packets between separate networks or subnets. Managed and unmanaged switches (Layer 2) only forward frames within the same network; they do not route between subnets unless specifically equipped with Layer 3 functionality. A wireless access point extends a Layer 2 network over radio, and a cable modem terminates a broadband WAN link-neither solves inter-subnet routing in this scenario.
