FC0-U71 Practice Question: A network administrator is setting up a small…
A network administrator is setting up a small office network. Which THREE devices are typically used to connect multiple computers and share resources? (Select exactly three.)
⚠ Common exam trap
Test-takers frequently confuse a hub with a switch, assuming both are equally suitable for connecting multiple computers, but the exam expects you to recognize that a hub is obsolete for modern resource sharing due to its lack of traffic management and collision handling.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Modem
A modem (modulator-demodulator) is correct because it converts digital signals from a local network into analog signals for transmission over telephone or cable lines, and vice versa, enabling internet connectivity. In a small office, a modem is typically the first device that connects to the ISP, allowing multiple computers to share a single internet connection. Without a modem, the network would lack the necessary interface to communicate with external wide-area networks (WANs).
