Ekahau Site Survey RF Coverage Configuration
Short answer
A Passive mode with two wireless adapters enables simultaneous multi-channel scanning for rapid RF coverage map generation.
Question
Key Takeaways
Tests knowledge of survey modes: passive scanning captures signal data without client association overhead, while dual adapters enable parallel channel scanning to maximize speed.
Determine the optimal Ekahau Site Survey configuration for rapid RF coverage mapping. Passive mode with two adapters is the correct choice for speed and accuracy in this scenario.
Common mistake: Choosing active mode (C or D) because it provides more detailed performance metrics, but this ignores the requirement for speed and the specific goal of verifying RF coverage maps rather than application throughput.
Expert Analysis
Why the Answer Is Correct
Passive mode is ideal for RF coverage verification because it listens to beacon frames from existing APs without requiring the survey device to associate with them. Using two wireless adapters allows the survey tool to scan multiple channels simultaneously (e.g., one for 2.4 GHz and one for 5 GHz), significantly reducing the time required to collect comprehensive data compared to a single adapter.
Why the Other Options Are Wrong
Active mode involves associating with APs and often exchanging data packets, which introduces latency and processing overhead that slows down the survey process. While active mode is useful for validating user experience and throughput, it contradicts the management's primary goal of creating coverage maps "as quickly as possible." Single adapter options are slower because they must scan channels sequentially rather than in parallel.
Community Comment Notes
The community largely agrees on option A. As Jonycici noted, "Using passive mode with two wireless adapters... allows for simultaneous scanning of multiple channels, thereby expediting the creation of accurate RF coverage maps." Another commenter, AdamNoe, emphasized that since the key word is "RF coverage," passive mode is sufficient and faster. The consensus highlights that active surveys are less efficient for pure coverage mapping tasks where speed is paramount.
Exam Strategy
When an exam question prioritizes 'speed' or 'quickly' for coverage maps, lean towards passive mode and multi-adapter setups. Active mode is reserved for questions emphasizing 'user experience,' 'throughput validation,' or 'application performance.'

AmrOoooo 👍 2 Answered CIn active mode, the survey tool actively sends probe requests and receives responses from the wireless network, which provides more detailed and accurate information about the network's performance and coverage. Using two wireless adapters in active mode allows you to simultaneously scan and collect data from multiple channels, significantly speeding up the process and improving the accuracy of your coverage maps

Jonycici 👍 2 Answered AA. Using passive mode with two wireless adapters in the Ekahau Site Survey tool allows for simultaneous scanning of multiple channels, thereby expediting the creation of accurate RF coverage maps. Active surveys, on the other hand, can be more time-consuming as they require the client device to associate with access points and perform data transfers, which is less efficient for quickly mapping coverage areas.
