220-1201 Practice Question: During a site survey, a technician needs to…
During a site survey, a technician needs to measure the signal strength of a wireless access point from various locations in an office to ensure adequate coverage. Which tool should be used for this task?
⚠ Common exam trap
In CompTIA A+ exams, candidates often confuse Wi-Fi analyzers with spectrum analyzers. A Wi-Fi analyzer measures signal strength from access points for coverage surveys, while a spectrum analyzer detects RF interference and noise.

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
✓
Wi-Fi analyzer
A Wi-Fi analyzer is the correct tool because it is specifically designed to measure wireless signal strength (RSSI), channel utilization, and interference from access points. During a site survey, the technician uses a Wi-Fi analyzer to collect real-time signal data from various locations, ensuring adequate coverage and identifying dead zones or co-channel interference.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Multimeter
Why it's wrong here
A multimeter measures voltage, current, and resistance, not wireless signal strength.
- ✓
Wi-Fi analyzer
Why this is correct
A Wi-Fi analyzer shows signal strength, channel usage, and interference, making it ideal for wireless site surveys.
- ✗
Spectrum analyzer
Why it's wrong here
A spectrum analyzer can measure RF interference across frequencies, but it is typically used for advanced troubleshooting, not simple signal strength measurement for coverage.
- ✗
Cable tester
Why it's wrong here
A cable tester is used for wired Ethernet cables, not for wireless signal measurement.
