Which of the following would prevent an active discovery toll like InSSIDer from detecting a wireless access point?

The correct answer is C. The AP doesn't respond to beacon packets without a specified SSID. Active tools like NetStumbler and InSSIDer work by sending out a constant stream of probe requests without an SSID. If an AP is configured to not respond to a probe that omits an SSID (another feature of SSID cloaking), NetStumbler and InSSIDer cannot determine the SSID. InSSIDer

Explanation

Active tools like NetStumbler and InSSIDer work by sending out a constant stream of probe requests without an SSID. If an AP is configured to not respond to a probe that omits an SSID (another feature of SSID cloaking), NetStumbler and InSSIDer cannot determine the SSID. InSSIDer does not send ICMP requests and does not need to authenticate to an AP to detect it.
