SY0-301 · Question #566
A computer supply company is located in a building with three wireless networks. The system security team implemented a quarterly security scan and saw the following. Which of the following is this…
The correct answer is A. Rouge access point. The company has three known wireless networks but the scan reveals four SSIDs, with 'Computer AreUs4' being an unauthorized access point not belonging to the organization. This is a classic rogue access point scenario where an unauthorized AP appears on the network.

Why each option
The company has three known wireless networks but the scan reveals four SSIDs, with 'Computer AreUs4' being an unauthorized access point not belonging to the organization. This is a classic rogue access point scenario where an unauthorized AP appears on the network.
A rogue access point is an unauthorized wireless access point that has been installed or connected to a network without the administrator's knowledge. The scan reveals four SSIDs when only three are authorized, meaning 'Computer AreUs4' is operating in the same building and could be used to intercept traffic or provide unauthorized network access. This is identified by comparing the known authorized SSIDs against those discovered during the wireless scan.
Near field communication (NFC) operates at very short range (a few centimeters) and would not appear as a Wi-Fi SSID in a wireless network scan.
Jamming involves deliberately interfering with wireless signals to disrupt communication, not creating an additional SSID on a wireless scan.
Packet sniffing is a passive technique for capturing network traffic and would not result in an additional SSID appearing in a wireless scan.
