I think the answer should be B: Aircrack-ng. It's made specifically for wifi networks. I havent been able to find anything that says Nikto does this. Just that is scans ports on web servers and verify server versions. Cant find are reason it would be A. https://www.aircrack-ng.org/

I feel aircrack ng would be more appropriate in this case

Nikto is right

The Aircrack-ng suite of utilities (aircrack-ng.org) is one of the early tools designed for wireless network security testing. Aircrack-ng is made up of a number of command-line tools. The principal tools in the suite are as follows: airmon-ng—Enable and disable monitor mode. airodump-ng—Capture 802.11 frames. Use this output to identify the MAC address of the access point (its Basic Service Set ID) and the MAC address of a victim client device. aireplay-ng—Inject frames to perform an attack to obtain the authentication credentials for an access point. This is usually performed using a deauthentication attack. Forcing the victim station to reauthenticate generates the required traffic. A deauthentication attack can also be used for DoS.

WiFi Specific Aircrack-ng Aircrack-ng is an 802.11 WEP and WPA-PSK keys cracking program that can recover keys once enough data packets have been captured. It implements the standard FMS attack along with some optimizations like KoreK attacks, as well as the all-new PTW attack, thus making the attack much faster compared to other WEP cracking tools. In fact, Aircrack-ng is a set of tools for auditing wireless networks

Did anyone stop to think that the first part of the question is a red herring? He wants to gain access to information found on the Hotel Network... Does the Hotel have a web site? Nikto is a tool used to test web-specific vulnerabilities... SQL inj, XSS, cross script... mcvbm got it but it flew over the rest of your heads...

Aircrack for sure, option B.

tcpdump sounds too difficult. See here https://networkengineering.stackexchange.com/questions/19802/tcpdump-and-listening-to-wifi-traffic-of-others. I would go for aircrack-ng. It is a more complete solution, being able to monitor, crack and attack.

First off this question is missing info, my thoughts: tcpdump, if your trying capture traffic to get guest credentials from people staying at the hotel, aka logging into accounts through websites or Aircrack-ng if they are trying to get the password to get authenticated access to the Hotels network. Nikto and Nessus you have 2 vulnerability scanners(nothing to do with the question)

The answer is Nikto because in the question it say "to gain access to information found on the hotel network?" Aircrack-ng is used for password cracking.

says nothing at all about wifi, therefore aircrack is not right. Think the answer is nikto

I think it is tcpdump! This would packet capture the info. Nikto is a web vulnerability scanner. Am I wrong?
