Question 1

Which wireless site survey tool feature allows a technician to visualize signal coverage as a color-coded overlay on a floor plan?

Accepted Answer

Heatmap generation

Answer

Heatmap generation overlays signal strength, SNR, or other RF metrics as color gradients on a floor plan, helping technicians identify coverage gaps.

Question 2

A technician uses Ekahau Pro to perform a passive survey. What is the primary function of a passive survey?

Accepted Answer

Listening to existing Wi-Fi signals without associating to an AP

Answer

A passive survey listens to 802.11 beacon and management frames without associating to any AP, capturing real-world signal data.

Question 3

In wireless network management software, what does an SNMP trap accomplish?

Accepted Answer

Sends an unsolicited alert from a device to the NMS when an event occurs

Answer

An SNMP trap is an asynchronous notification sent by a managed device to the NMS when a specific condition or threshold is met.

Question 4

Which tool would a CWS technician use to identify the exact frequency and power level of a non-Wi-Fi interference source like a microwave oven?

Accepted Answer

Spectrum analyzer

Answer

A spectrum analyzer captures all RF energy across a frequency range, including non-802.11 sources, making it ideal for identifying interference.

Question 5

What is the primary purpose of the iPerf tool in a wireless network deployment?

Accepted Answer

Measuring throughput and latency between two endpoints

Answer

iPerf is a network testing tool that measures TCP/UDP bandwidth, latency, and packet loss between a client and server endpoint.
