You work as a remote support technician. A user named Rick calls you for support. Rick wants to connect his LAN connection to the Internet. Which of the following devices will you suggest that he use?

A router connects separate networks together - specifically, it routes traffic between a local area network (LAN) and the Internet (a WAN), making it the only device here capable of doing what Rick needs. The other options are all Layer 1 or Layer 2 devices that operate within…

Explanation

A router connects separate networks together - specifically, it routes traffic between a local area network (LAN) and the Internet (a WAN), making it the only device here capable of doing what Rick needs. The other options are all Layer 1 or Layer 2 devices that operate within a LAN: a hub broadcasts frames to all ports with no intelligence, a repeater simply amplifies signals to extend cable distance, a bridge segments a LAN into two collision domains, and a switch forwards frames between devices on the same network using MAC addresses - none of them can route packets across different networks. Memory tip: Think "R for Router = R for Roads between cities" - just as roads connect cities (networks), a router connects your LAN to the Internet.
