Ekahau Site Survey RF Coverage Configuration
An engineer is deploying new APs to serve IEEE 802.11g through 802.11ac clients and wants to use the Ekahau Site Survey tool to verify RF coverage. Management wants the engineer to verify and create coverage maps as quickly as possible. Which configuration accomplishes the goal?

Community Insight
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.
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.'
Frequently Asked Questions
Why is passive mode preferred over active for coverage maps?
Passive mode only listens to beacons, avoiding association overhead. This makes it faster for visualizing signal strength and coverage areas.
Does using two adapters increase accuracy?
It increases efficiency by allowing parallel channel scanning. It doesn't necessarily improve per-point accuracy but drastically reduces total survey time.
