FC0-U71 Infrastructure Practice Question
A technician is setting up a brand-new all-in-one desktop for a home user. The user wants to connect to the internet using the existing home router without running any cables. Which built-in capability should the technician verify is working?
⚠ Common exam trap
Many exam-takers confuse any wireless technology, such as Bluetooth, with the specific wireless networking standard used to reach a router for internet access.
Answer choices
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
✓
Wi-Fi adapter
The user wants internet access without cables, so the desktop must have a working Wi-Fi adapter to connect to the home router wirelessly. Ethernet would require a cable, while Bluetooth and an optical drive do not provide network access at all. Only Wi-Fi meets the stated need.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Wi-Fi adapter
Why this is correct
A Wi-Fi adapter allows the desktop to connect wirelessly to the home router, which is exactly what the user requested. All-in-one systems often include integrated Wi-Fi, so the technician should confirm it is enabled and can see the network. This satisfies the no-cables requirement directly.
- ✗
Ethernet port
Why it's wrong here
An Ethernet port provides a wired connection and would require a cable to the router, contradicting the user's request to avoid cables. While Ethernet is reliable and fast, it does not meet the wireless requirement. The technician should not rely on it for this setup.
- ✗
Optical drive
Why it's wrong here
An optical drive reads and writes discs and has no role in network connectivity. It does not provide any path to the home router or the internet. This component is irrelevant to the user's wireless internet requirement.
- ✗
Bluetooth adapter
Why it's wrong here
Bluetooth is designed for short-range connections to peripherals like keyboards and mice, not for connecting to a router for internet access. It cannot provide the network connectivity the user needs. Verifying Bluetooth would not help the desktop reach the internet.
