FC0-U71 Infrastructure Practice Question
A company is setting up a new office and needs to connect multiple computers within the same building to share files and printers. Which type of network should they implement?
⚠ Common exam trap
The trap is choosing WLAN because modern offices often use Wi-Fi, but the question asks for the general network type for a building, which is LAN regardless of medium.
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
✓
LAN
A LAN (Local Area Network) connects devices within a single building or campus to share files, printers, and other resources. The scenario describes multiple computers in one building sharing resources, which is the textbook definition of a LAN. WANs span large geographic areas, PANs are personal-range, and WLANs are wireless-specific.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
WAN
Why it's wrong here
A WAN spans cities or countries, so it cannot describe connectivity confined to one building. It is tempting because WANs also link computers and share resources, and would be correct for joining the new office to a distant branch or data centre.
- ✓
LAN
Why this is correct
A LAN connects computers within one building so they can share files and printers, matching the office scenario exactly. Ethernet or Wi-Fi provides the local connectivity. A WAN or MAN would span beyond the building, which the stem does not require.
- ✗
PAN
Why it's wrong here
A PAN covers a single person's devices within a few metres, so it cannot connect multiple computers across a building. It is tempting because PANs do share files and peripherals, and would be correct for linking a phone, headset and laptop personally.
- ✗
WLAN
Why it's wrong here
A WLAN provides wireless connectivity, which suits mobile devices but not a fixed office of wired computers sharing files and printers. It is tempting because wireless removes cabling, yet the requirement is a stable wired local network, which a LAN delivers through Ethernet switches.
