Which of the following would BEST segment a LAN while providing additional network ports?

The correct answer is C. Switch. A managed or unmanaged switch segments a LAN into separate collision domains per port and simultaneously provides multiple ports to connect end devices.

Why each option

A managed or unmanaged switch segments a LAN into separate collision domains per port and simultaneously provides multiple ports to connect end devices.

AAccess point

A wireless access point extends a LAN over Wi-Fi and adds wireless clients but does not segment the wired LAN or add wired network ports.

BModem

A modem connects a LAN to a WAN or ISP service and does not segment the internal LAN or provide additional internal network ports.

CSwitchCorrect

A switch operates at Layer 2 and creates a dedicated collision domain for each connected port, which segments traffic and reduces collisions compared to a hub. Each port also represents an individual connection point, so a 24-port switch both segments the LAN into 24 domains and provides 24 additional connection ports for workstations, printers, and other devices - directly addressing both requirements in the question.

DHub

A hub repeats all traffic to every port, creating a single shared collision domain rather than segmenting it, and offers no performance or traffic isolation improvement over a direct connection.
