What are two advantages of conducting an active survey versus a passive survey when verifying RF coverage? (Choose two.)
The correct answer is A. verifies packet loss B. verifies roaming. An active survey requires the survey device to fully associate with the WLAN and transmit real traffic, whereas a passive survey only listens (sniffs) without associating.

Explanation
An active survey requires the survey device to fully associate with the WLAN and transmit real traffic, whereas a passive survey only listens (sniffs) without associating. Active surveys provide two unique advantages: (A) Verifying packet loss - since actual data frames are sent and acknowledged, you can measure retransmissions and dropped packets, validating real application performance; (B) Verifying roaming - because the client is associated, it can actually roam between APs, allowing you to confirm seamless handoffs and measure roaming latency. Passive surveys can verify SNR, signal level, and detect interferers without association, so those are not unique to active surveys. Active surveys reflect real-world client behavior more accurately than passive surveys.
