Morris, an attacker, wanted to check whether the target AP is in a locked state.

In CEH v13 Module 11: Hacking Wireless Networks, WPS (Wi-Fi Protected Setup) is discussed as a vulnerable configuration that can be exploited using tools like Reaver and wash.

wash is a command-line utility used to detect WPS-enabled Access Points.

It provides information about:

Whether WPS is enabled or locked.

Signal strength, BSSID, channel, etc.

Very useful before attempting WPS PIN attacks.

Option Clarifications:

B. ntptrace: Used for querying NTP servers, not wireless networks.

C. macof: Part of dsniff suite; floods network with MAC addresses (DoS tool).

D. net view: Windows command for listing network shares, not for wireless or WPS.

Correct answer is A. wash.
