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.
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
✓
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
Correct. WLAN with wireless bridges can connect buildings within a campus, providing a simple, cable-free network without internet.
- ✗
Wireless Personal Area Network (WPAN)
Why it's wrong here
Incorrect. WPAN (e.g., Bluetooth) has a range of about 10-100 meters, insufficient for 200-meter inter-building links.
- ✗
Metropolitan Area Network (MAN)
Why it's wrong here
Incorrect. MAN covers a citywide area, which is overkill and typically more expensive/complex than needed.
- ✗
Wide Area Network (WAN)
Why it's wrong here
Incorrect. WAN connects across large distances (e.g., multiple cities) and usually requires internet or leased lines, adding cost and complexity.
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.
