• Question 379:

  Which of the following would MOST likely be used to connect one or more devices to the Internet in a SOHO?

  A. Hub

  B. Ethernet gateway

  C. Wireless access point

  D. Router

  Correct Answer: D

  A router is a device that connects one or more networks, such as a home or small office network, to the internet. It allows multiple devices to share a single internet connection and provides network address translation (NAT) to enable communication between the devices on the local network and the internet. A hub, Ethernet gateway, or wireless access point does not provide this functionality. A router is the most likely device to be used to connect one or more devices to the internet in a SOHO. A router can provide network address translation (NAT), firewall protection, and other features that are important for securing and managing a network.
