To troubleshoot some possible RF coverage issues in a large auditorium, you would
like to see a heatmap of every AP (both legitimate and rogue) that can be received at
every location. You would also like to see the signal strength of each AP, SNR, and
evidence of any co-channel interference. Which one of the following survey types
would be best for this purpose?
- A.Predictive survey
- B.Passive survey
- C.Active survey
- D.Performance survey
- Answer & Explanation
- Report
Answer : [B]
Explanation :
Explanation :
| A passive site survey would provide all of the information needed. Because the passive survey tool listens to all APs that are in range of a location, you would learn of legitimate and rogue APs as well as the RF conditions. |
