Two departments are on different subnets and must reach each other. The closet has only a switch. Which device should be added?
Select an answer to reveal the explanation.
Short Explanation
A switch can pass traffic inside a neighborhood. These departments are on different streets, so you add a router to carry traffic between them. Another simple switch, a passive jack field, and a wireless radio do not route from one subnet to the other.
Full Explanation
A router forwards packets between subnets. The departments are on different subnets and the closet has only a switch, which does not route, so a router is the device to add. A second unmanaged switch still only forwards frames inside a broadcast domain. It does not route between subnets. A patch panel terminates cables. It does not forward packets. An access point provides a wireless LAN. Wireless clients still need a router if they must reach a different subnet, and the access point itself is not that router. Exam caveat: a layer-3 switch can route as well. The closet in this stem has only a switch that is not doing that job, so a router is the missing piece. Operational check: install the router on both subnets, set the hosts' gateways to it, and ping from one department to the other. Set each department's gateway to the new router and ping across. Ping a host in the other department by address. Label the router ports with the department subnets.
