CWS WLAN Hardware & Software Components 3

Question 1

Which of the following best describes a mesh access point in a WLAN deployment?

Accepted Answer

An AP that uses wireless backhaul to connect to the wired network

Answer

Mesh APs use one radio as a wireless backhaul to connect to a root AP or other mesh nodes, eliminating the need for a wired Ethernet connection at every AP location.

Question 2

What is the purpose of an RF spectrum analyzer in WLAN troubleshooting?

Accepted Answer

To identify non-802.11 interference sources in the RF spectrum

Answer

An RF spectrum analyzer detects and classifies non-802.11 RF sources such as microwave ovens, Bluetooth devices, and cordless phones that can cause interference.

Question 3

A dual-band access point has two radios. One is operating on the 2.4 GHz band. What band does the second radio typically operate on?

Accepted Answer

5 GHz

Answer

Dual-band APs simultaneously operate on both the 2.4 GHz and 5 GHz bands, allowing clients to connect on either band based on capability and network conditions.

Question 4

What hardware feature allows a tri-radio access point to dedicate one radio exclusively to monitoring the RF environment?

Accepted Answer

Dedicated scanning radio

Answer

A dedicated scanning radio (sometimes called a security radio) in a tri-radio AP continuously monitors all channels for rogue APs, interference, and security threats without impacting client service.

Question 5

Which software tool is used by WLAN administrators to plan AP placement, predict coverage, and model RF propagation before deployment?

Accepted Answer

Wireless site survey / RF planning software

Answer

RF planning tools like Ekahau, AirMagnet, or iBwave use building floor plans and AP specs to predict signal coverage, capacity, and interference before physical deployment.
