Explanation
The inetd.conf file is the configuration file that needs to be edited before the TFTP service will start on a BSD system. The inetd daemon handles the TFTP service and other network services, and its configuration file contains settings that determine howthese services are managed. To enable the TFTP service, the corresponding entry in inetd.conf must be uncommented and properly configured. References:

Explanation
The zpool create command is used to initialize ZFS on one or more block devices and create a storage pool. A storage pool is a collection of devices that provide physical storage and data replication for ZFS datasets. The zpool create command takes the name of the pool and the devices to be added as arguments. For example, zpool create mypool c0t0d0 c0t1d0 c0t2d0 would create a pool named mypool with three devices. The other options are either invalid or do not initialize ZFS. References: 1:

Explanation
The command grep "non [-] disclosure" legalfile matches the lines in the file that contain the pattern non [-] disclosure, where the brackets indicate a character class that matches either a space or a dash. Therefore, the lines that contain non-disclosure or non - disclosure are matched by the command, while the line that contains disclosure only is not matched. The file has two lines that contain non-disclosure, so the correct answer is E. non-disclosure and non-disclosure Only. References:

Explanation
The last command displays a list of the last logged in users on a BSD system. The output consists of several columns that show the user name, the terminal name, the login date and time, and the logout date and time or the current status. The option C is the only line that matches the format of the last command output. It shows that the user root logged in on the terminal ttyv0 on Saturday, May 18, 2023 at 13:35 and is still logged in. The other options are either invalid lines or belong to othercommands or sources. For example, option A is the output of the uptime command, option B is a line from the /var/log/auth.log file, option D is a line from the ps command, and option E is the output of the uname -a command.
