FC0-U71 Tech Concepts and Terminology Practice Question
A small office wants wireless devices to connect to the corporate network without running cables to each desk. The administrator must choose a technology that provides wireless local area network connectivity using radio frequencies. Which technology should be selected?
⚠ Common exam trap
The trap here is treating any wireless technology as interchangeable for LAN access, when Bluetooth and NFC are short-range personal networking technologies with far lower throughput and range.
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
Wi-Fi, standardized under IEEE 802.11, is the technology built specifically for wireless local area networking over radio frequencies. It provides the range, client density, and throughput that an office needs, unlike Bluetooth and NFC, which serve short-range personal connections, or infrared, which requires direct line of sight and offers limited bandwidth.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
NFC
Why it's wrong here
Near field communication operates only within a few centimeters and is intended for tap-to-pay, access badges, and quick pairing handshakes. Its extremely short range and very low data rate make it unsuitable for connecting desktop or laptop systems to shared network resources. It simply cannot carry normal office traffic between workstations and servers.
- ✓
Wi-Fi
Why this is correct
Wi-Fi is the IEEE 802.11 family of wireless LAN standards that uses radio frequencies to connect devices to an access point and, through it, to the corporate network. It supports dozens of concurrent clients at ranges of tens of meters indoors and delivers the throughput needed for file sharing, printing, and internet access, which matches the stated requirement exactly.
- ✗
Bluetooth
Why it's wrong here
Bluetooth is a short-range wireless personal area network technology designed to connect peripherals such as headsets, keyboards, and mice to a host device. Its typical range is around ten meters and its throughput is far lower than what an office LAN requires. It cannot provide the coverage or bandwidth needed for multiple workstations to access shared network resources across a building.
- ✗
Infrared
Why it's wrong here
Infrared communication requires an unobstructed line of sight between transmitter and receiver and is easily blocked by walls, furniture, or even a person walking through the path. Its bandwidth is modest and it has largely been replaced by radio-based wireless networking. It cannot reliably serve multiple office devices spread across separate rooms and desks.
