When a post-installation audit is performed using the Ekahau Survey tool, which two steps are associated with the passive portion of the audit? (Choose two.)

Question

Options

• ACheck to see if the signal levels on other access points that are heard on the same channel are at
• BSurvey by SSID to ensure that smooth roaming is taking place
• CVerify that the real-world network traffic (for example, physical data rate, packet loss, etc.) meets
• DWhen you have completed the post-installation surveys, compare them to the surveys that were
• EVerify that user applications are running smoothly over the wireless network

• A
  78% (52)
• B
  12% (8)
• C
  3% (2)
• E
  7% (5)

Explanation

A passive survey involves walking the survey area while the tool listens and records beacon frames and signal levels without actively transmitting or associating to a network. (A) Checking signal levels of neighboring APs heard on the same channel is a passive measurement-the tool simply receives and records RSSI from those beacons with no active transmission. (D) Comparing post-installation survey results to the pre-installation/design surveys is an analysis step performed on passively collected data. Options C and E involve active traffic testing (measuring throughput, packet loss, application performance), which requires an active association and data transmission-these belong to the active portion of the audit. Option B (surveying by SSID for roaming) also requires associating and actively roaming between APs.
