FC0-U71 Practice Question: A home user wants to connect a desktop computer…
A home user wants to connect a desktop computer to the internet using a wireless connection. The computer does not have built-in Wi-Fi. What is the simplest and most cost-effective solution? The user has a wireless router already installed and working.
⚠ Common exam trap
The trap here is that candidates may overthink the solution and choose a more complex option like powerline adapters or Ethernet, missing that the simplest fix is a low-cost wireless adapter that directly addresses the missing Wi-Fi hardware.

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
✓
Install a wireless network adapter (USB or PCIe)
A wireless network adapter (USB or PCIe) adds Wi-Fi capability to a desktop that lacks it, directly connecting to the existing wireless router. This is the simplest and most cost-effective solution because it requires no new infrastructure or cabling, and USB adapters are plug-and-play with minimal setup.
