CompTIA A+ Core 1 (220-1101) — Question 103

Which of the following networking devices will MOST likely need to be installed in between the ISP and the LAN in a SOHO environment?

Answer options

• A. Switch
• B. Firewall
• C. Cable modem
• D. Router
• E. Access point

Correct answer: D

Explanation

The correct answer is D, the Router, as it connects the local area network (LAN) to the internet provided by the ISP. While a Cable modem (C) can also be necessary for internet connectivity, the Router is essential for managing traffic between the two networks. A Switch (A), Firewall (B), and Access point (E) serve different roles within the network and do not directly connect the ISP to the LAN.
