What primary metric of scanning can stations use to select the best AP for connectivity to the desired BSS?

Question

Options

• ASignal strength of AP beacons received.
• BPING latency when testing against an Internet server.
• CThroughput speed in Mbps.
• DFCS errors in frames transmitted to and from the AP.

• A
  89% (34)
• B
  3% (1)
• C
  5% (2)
• D
  3% (1)

Explanation

When a station scans for available wireless networks, it listens for beacon frames sent by APs. A beacon frame contains information about the BSS, such as SSID, supported rates, channel, security, etc. The station also measures the signal strength of the beacon frames, which indicates how well the station can communicate with the AP. The signal strength is usually expressed in dBm or RSSI units. The higher the signal strength, the better the connection quality and performance. Therefore, the station can use the signal strength of AP beacons as the primary metric to select the best AP for connectivity to the desired BSS. Exam Questions, Study Guides, Practice Tests.
