CompTIA A+ Core 1 (220-1001) — Question 14

Which of the following connects a PC to its default gateway?

Answer options

• A. NIC
• B. Switch
• C. Router
• D. Cable modem

Correct answer: B

Explanation

The correct answer is B, as a switch connects multiple devices within a local area network and facilitates their communication with the default gateway. While the NIC (A) allows the PC to connect to the network, it does not serve as a connection point to the gateway itself. A router (C) is responsible for routing traffic between different networks, and a cable modem (D) connects to the internet service provider, not directly to the PC's default gateway.
