Which directories contain start scripts for services on FreeBSD? (Choose TWO correct answers.)  /etc/red/  /usr/rc.d/  /var/boot/rc.d/  /usr/local/etc/rc.d/  /boot/red/ ExplanationThe directories that contain start scripts for services on FreeBSD are /usr/rc.d/ and /usr/local/etc/rc.d/. The/usr/rc.d/ directory contains the system-provided scripts for the base system services, such as cron, sshd, syslogd, etc. The /usr/local/etc/rc.d/ directory contains the scripts for the additional services installed from ports or packages, such as apache, mysql, nginx, etc. These scripts follow the BSD rc.d framework, which allows for fine-grained control and customization of the startup process. The scripts are invoked by the main/etc/rc script, which sources the /etc/rc.conf file for configuration optionshttps://docs.freebsd.org/en/articles/rc-scripting/Q14. What FreeBSD and NetBSD command manages services started at boot time? (Specify ONLY the command without any path or parameters.) sysrcExplanationThe sysrc command is used in FreeBSD and NetBSD to manage system-wide daemon and service settings, including those that are started at boot time. It allows administrators to safely edit system rc files, such as /etc/rc.conf, where services to be started at boot time are specified1.References:FreeBSD Handbook – rc.confFreeBSD Man Pages – sysrcQ15. Which option of the crontab command opens the current user’s crontab in an editor?  -w  -i  -vi  -rw  -e ExplanationThe -e option of the crontab command opens the current user’s crontab in an editor. The editor used is determined by the environment variables VISUAL or EDITOR. If neither of these variables is set, the default editor is vi. The user can edit the crontab file to add, modify, or delete cron jobs, which are scheduled commands or scripts that run at a specified time or interval. The crontab file has the following format:minute hour day-of-month month day-of-week commandEach field can be a number, a range, a list, or an asterisk (*), which means all possible values. The command can be any valid shell command or script. For example, the following crontab entry runs the backup.sh script every day at 2:30 AM:30 2 * * * /home/user/backup.shTo save and install the crontab file, the user needs to exit the editor. The crontab command will check the syntax of the file and report any errors. If the file is valid, it will be installed and the cron daemon will execute the cron jobs according to the schedule.

Which command can be used to display the local filesystems that are currently mounted’?  cat /etc/fstab  df -h C du -s  mount -a  rpcinfo ExplanationThe command df -h displays the disk space usage of all mounted filesystems in a human-readable format. It shows the size, used, available, and percentage of each filesystem, as well as the mount point. This command can be used to check the local filesystems that are currently mounted.https://unix.stackexchange.com/questions/24182/how-to-get-the-complete-and-exact-list-of-mounted-filesystemshttps://www.tecmint.com/find-mounted-file-systems-in-linux/https://itslinuxfoss.com/check-filesystem-mounted-linux/Q17. What is the purpose of the file /boot/loader. conf on OpenBSD?  Specify where to install the bootloader.  Specify the kernel image to load.  Specify options for starting operating systems other than BSD.  Specify kernel configuration options.  Specify which system services to start. ExplanationThe file /boot/loader.conf on OpenBSD is used to specify the kernel image that the bootloader should load.This file contains various settings that can be used to control the boot process, including kernel parameters and device driver options.References:boot(8) – OpenBSD manual pagesQ18. What symbol is used in the vi editor to start the forward search for a string? (Specify ONLY the single character symbol without any parameters) /ExplanationThe symbol / is used in the vi editor to start the forward search for a string. It is followed by the string to be searched and then Enter to execute the search. The vi editor highlights the first occurrence of the string after the cursor position. To find the next occurrence of the string in the same direction, press n. To find the previous occurrence of the string in the opposite direction, press N.

When replacing the system MTA with another mail server program, which configuration file needs to be updated with the path to the new MTA?  mail.conf  mailer.conf  mta.conf  postfix.conf  sendmail. conf ExplanationThe mailer.conf file is used to configure the mailer programs on a BSD system. It allows the system administrator to replace the default mailer programs, such as sendmail, with alternative ones, such as postfix or exim. The mailer.conf file contains a series of entries, each consisting of a label, an equal sign, and a command. The label is the name of the default mailer program, and the command is the path to the alternative mailer program that will be executed instead. For example, to replace sendmail with postfix, the mailer.conf file should contain the following entries:sendmail /usr/local/sbin/sendmail send-mail /usr/local/sbin/sendmail mailq /usr/local/sbin/sendmail newaliases/usr/local/sbin/sendmail hoststat /usr/local/sbin/sendmail purgestat /usr/local/sbin/sendmail The mailer.conf file is read by the mailwrapper program, which is a binary that acts as a wrapper for the mailer programs. The mailwrapper program is installed as /usr/sbin/sendmail and /usr/libexec/sendmail/sendmail, and it invokes the appropriate mailer program based on the mailer.conf file. Therefore, to replace the system MTA with another mail server program, the mailer.conf file needs to be updated with the path to the new MTA.References:Chapter 31.

Which of the following chmod commands changes the permission of the file text. txt to 750?  chmod user:rw, group:r, other:x  chmod text.txt=u:rw,g:r,o:r  chmod u=rwx,g=rx,o= text.txt  chmod -u rw -g rx -o – text.txt  chmod text.txt 750 ExplanationPermissions involve read, write, and execute roles that can be assigned to the owner, a group, or other users1.To use the chmod command, you must specify the permission you want to set and the file or directory you want to modify1.For example,chmod +rwx filenameto add permissions,chmod -rwx directorynameto remove permissions, orchmod +x filenameto allow executable permissions2.There are two ways to specify the permissions with the chmod command: symbolic notation and numeric notation1.Symbolic notation uses letters and symbols to represent the user classes and the permissions1.Numeric notation uses octal numbers (0-7) to represent the permissions for each user class1.Each octal digit corresponds to a combination of read , write (w), and execute (x) permissions, as shown in the table below3:Octal digitBinary representationPermissions0000–1001-x2010-w-3011-wx4100r-5101r-x6110rw-7111rwxTo use numeric notation, you need to provide three octal digits, one for each user class (owner, group, and others)1.For example,chmod 644 filenamemeans that the owner has read and write permissions (6), the group has read permissions (4), and others have read permissions (4)1.In this question, the desired permission for the file text.txt is 750, which means that the owner has read, write, and execute permissions (7), the group has read and execute permissions (5), and others have no permissions (0)1. Therefore, the correct chmod command to change the permission of the file text.txt to 750 ischmod text.txt 750.References:1: Chmod Command in Linux (File Permissions) | Linuxize2: How to change directory permissions in Linux | Pluralsight3: How to Use the chmod Command on Linux – How-To GeekQ21. Which line in a cron job runs myscript once per hour?  ***** /pathto/myscript  0 * * * * /pathto/myscript  * 0 * * * /pathto/myscript  * * o * * /pathto/myscript  * * * o * /pathto/myscript ExplanationThe cron job syntax consists of five fields that specify the time and date of execution, followed by the command or script to run. The fields are: minute, hour, day of month, month, and day of week. Each field can have a specific value, a range, a list, a wildcard (), or a step value. The wildcard () means any possible value for that field. The option B sets the minute field to 0 and the hour field to *, which means the script will run at the 0th minute of every hour, regardless of the day, month, or weekday. This is equivalent to once per hour.The other options are either invalid syntax or do not match the desired frequency. For example, option A sets all fields to *, which means the script will run every minute of every hour of every day, month, and weekday.Option C sets the minute field to * and the hour field to 0, which means the script will run every minute of the0th hour, or once per day at midnight. Option D has a typo (o instead of *) and option E sets the day of month field to o, which is not a valid value.

Which command updates the database used by locate to find files’?  searchdb  locate.updatedb  find  whereis  which ExplanationThe command locate.updatedb updates the database used by locate to find files. The locate command searches for files by name in a pre-built database of files and directories. The database is usually updated periodically by a cron job, but the locate.updatedb command can be used to manually update it. The command may require root privileges to run, depending on the system configuration.

What file contains the configuration for the network interface em0on an OpenBSD system’? (Specify the full name of the file, including path.) /etc/hostname.em0ExplanationThe file /etc/hostname.em0 contains the configuration for the network interface em0 on an OpenBSD system.This file specifies the IP address, netmask, gateway, and other options for the interface. The file is read by the netstart script during boot or when the interface is restarted. The file name is derived from the interface name, which is usually based on the driver name and the device number. For example, em0 is the first interface using the em driver, which supports Intel PRO/1000 network adapters.References:Networking | OpenBSD Handbook[hostname.if(5) – OpenBSD manual pages]Q24. What is the purpose of the nice command’?  Run a command with the permissions of another user  Run a command with limited access to a specified directory  Run a command with additional filesystem permissions  Run a command with additional secondary groups.  Run a command with a non-standard priority. ExplanationThe nice command is used to run a command with a modified scheduling priority, which affects how much CPU time the command receives. The priority can be specified by the -n option, which takes an integer value between -20 and 19, where lower values indicate higher priority. By default, the nice value is incremented by10, which means the command runs with lower priority than normal. Only the superuser can specify a negative increment, which means the command runs with higher priority than normal. For example, the command nice-n 5 date runs the date command with a priority of 5, while the command nice -n -10 ls runs the ls command with a priority of -10, but only if the user is the superuser. The nice command is useful for running CPU-intensive commands that do not need to finish quickly, or for running commands that need more CPU time than normal.

Which FreeBSD command updates packages to newer versions’?  pkg update  pkg refresh  pkg upgrade  pkg audit  pkg pull ExplanationThe command pkg upgrade is used to update FreeBSD packages to newer versions. It compares the versions of installed packages with those in the repositories and performs upgrades as necessary. The pkg update command is used to update the repository catalog, but it does not perform the actual package upgrades1.References:FreeBSD Handbook – Packages and PortsQ26. Which device stands for the first BSD disk slice in the disk label on the first partition on the second SATA disk on OpenBSD?  /dev/sdla  /dev/d2sl  /dev/slld2  /dev/sdlp2d  /dev/sata2a ExplanationAccording to the BSD disklabel documentation1, the device name for a BSD disk slice consists of three parts:the disk name, the partition letter, and the slice number. The disk name is determined by the driver and the order of detection, and it usually follows the pattern of sdX, where X is a letter from a to z. The partition letter is a lowercase letter from a to p, excluding c, which is reserved for the whole disk. The slice number is a decimal number from 0 to 15, indicating the MBR partition that contains the BSD disklabel. Therefore, the device name for the first BSD disk slice in the disk label on the first partition on the second SATA disk on OpenBSD is /dev/sdlp2d, where sdl is the disk name, p is the partition letter, and 2 is the slice number.References1: BSD disklabel – WikipediaQ27. Which of the following tar options handle compression’? (Choose TWO correct answers)  -x  -c  -z  -J  -v ExplanationThe tar command is used to create or extract compressed archive files on BSD systems. It can handle various compression formats, such as gzip, bzip2, xz, and lzma. The tar command takes different options to specify the compression type, such as -z for gzip, -j for bzip2, -J for xz, and -Z for lzma. The other options are not related to compression, but to other functions of the tar command, such as -x for extracting, -c for creating, and -v for verbose output.

When using the default TFTP server on a BSD system, which configuration file needs to be edited before the TFTP service will start?  inetd.conf  init.conf  rc.conf  tftpd.conf  service, conf ExplanationThe 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.
