Dell EMC Associate – Midrange Storage — Question 12

Which Layer 1 device can be used to enlarge the area covered by a single LAN segment?

Answer options

• A. Router
• B. Repeater
• C. Switch
• D. NIC

Correct answer: B

Explanation

The correct answer is B, Repeater, as it functions at Layer 1 and amplifies signals to extend the distance over which data can travel in a LAN. A Router (A) operates at Layer 3 and is used for directing traffic between different networks, while a Switch (C) works at Layer 2 to connect devices within the same network. A NIC (D) is a network interface card that connects a device to a network but does not extend the LAN segment.
