According to the scenario, John wants to break the my_backup.tgz file into two files in which the size of the first file named my_backup.tgz.aa should be 600MB and that of the second file named my_backup.tgz.ab should be 200MB. Hence, he will use the the split --verbose -b 600 my_backup.tgz my_backup.tgz. command, which will automatically break the first file into 600MB named my_backup.tgz.aa, and the rest of the data (200MB) will be assigned to the second file named my_backup.tgz.ab. The reason behind the names is that the split command provides suffixes as 'aa', 'ab', 'ac', ..., 'az', 'ba', 'bb', etc. in the broken file names by default. Hence, both conditions, the file names as well as the file sizes, match with this command. Note: If the size of the tar file my_backup.tgz is 1300MB, the command split --verbose -b 600 my_backup.tgz my_backup.tgz. breaks the my_backup.tgz file into three files, i.e., my_backup.tgz.aa of size 600MB, my_backup.tgz.ab of size 600MB, and my_backup.tgz.ac of size 100MB.

John can use the UserInfo, PsFile, and PsPasswd tools in the enumeration phase. UserInfo is a utility that retrieves all available information about any known user from any Windows 2000/NT operating system (accessible by TCP port 139). UserInfo returns mainly the following information: SID and Primary group Logon restrictions and smart card requirements Special group Password expiration Note: UserInfo works as a NULL user even if the RestrictedAnonymous value in the LSA key is set to 1 to specifically deny anonymous enumeration. PsFile is a command-line utility that shows a list of files on a system that are opened remotely. It also allows a user to close opened files either by name or by a file identifier. The command syntax for PsFile is as follows: psfile [\\RemoteComputer [-u Username [-p Password]]] [Id | path] [-c] -u specifies the optional user name for logging in to a remote computer. -p specifies a password for a user name. If this is omitted, the user is prompted to enter the password without it being echoed to the screen. Id is the identifier of the file about which the user wants to display information. -c closes the files identifed by the ID or path. PsPasswd is a tool that helps Network Administrators change an account password on the local or remote system. The command syntax of PsPasswd is as follows: pspasswd [\\computer[,computer[,..] | @file [-u user [-p psswd]] Username [NewPassword]

AirSnort is a Linux-based WLAN WEP cracking tool that recovers encryption keys. AirSnort operates by passively monitoring transmissions. It uses Ciphertext Only Attack and captures approximately 5 to 10 million packets to decrypt the WEP keys. Answer: C is incorrect. Kismet is an IEEE 802.11 wireless network sniffer and intrusion detection system.
