220-1201 WLAN Practice Question
A small business owner wants to set up a network that covers three separate buildings within a 200-meter radius, with no internet access required between them. They need a simple, low-cost solution that can be installed quickly without running cables between buildings. Which network type should be recommended?
⚠ Common exam trap
The trap is choosing WPAN due to 'simple low-cost,' but WPAN range is too short. WLAN can be extended with bridges, making it suitable for nearby buildings.

Correct answer & explanation
✓
Wireless Local Area Network (WLAN)
A Wireless Local Area Network (WLAN) is the best choice because it can connect multiple buildings using wireless bridges or mesh networking, covering a 200-meter radius without cables. It is simple, low-cost, and does not require internet access. WPAN (Bluetooth/ZigBee) has too short a range (typically <100m) for inter-building connections. MAN and WAN are designed for larger geographic areas and often involve higher costs and internet connectivity.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Wireless Local Area Network (WLAN)
Why this is correct
A WLAN uses radio links between access points and clients, so no cabling between the three buildings is needed, satisfying the no-cable constraint. Within a 200-metre radius, standard Wi-Fi gear covers all sites cheaply and installs quickly, and it operates independently of any internet connection.
- ✗
Wireless Personal Area Network (WPAN)
Why it's wrong here
A WPAN covers roughly 10 metres around one person via Bluetooth or Zigbee, so it cannot bridge three buildings 200 metres apart. It is tempting because WPANs are wireless and cable-free, but that role suits linking personal devices such as headsets, keyboards and wearables, not inter-building connectivity.
- ✗
Metropolitan Area Network (MAN)
Why it's wrong here
A MAN interconnects networks across a city using carrier infrastructure such as fibre rings, so it exceeds a 200-metre radius and requires provider involvement rather than a quick, low-cost install. It is tempting because MAN links separate buildings, but that fits a campus or city-scale deployment, not three nearby structures.
- ✗
Wide Area Network (WAN)
Why it's wrong here
A WAN spans large geographic areas using leased telecommunications links, so it neither suits a 200-metre radius nor avoids cabling or recurring carrier costs. It is tempting because WAN connects separate sites, which matches the three buildings, but that applies to distant offices linked by provider circuits.
Quick reference
AAA Protocol Comparison
| Protocol | Port(s) | Encryption | Transport | Primary Use |
|---|---|---|---|---|
| RADIUS | 1812 / 1813 | Password only | UDP | Network access control |
| TACACS+ | 49 | Full packet | TCP | Device administration |
| Diameter | 3868 | Full session | TCP / SCTP | Carrier / mobile networks |
| 802.1X | — | EAP-based | Layer 2 | Port-based access control |
TACACS+ encrypts the entire packet; RADIUS only encrypts the password field — a key exam distinction.
