Where are user specific crontabs stored?
- A. As individual per-user files in /etc/cron.user.d.
- B. In the .crontab file in the user's home directory.
- C. In the file /var/cron/user-crontab which is shared by all users.
- D. As individual per-user files within /var/spool/cron.
- E. In the database file /etc/crontab.db which is shared by all users.
Answer: D
Explanation:
The user-specific crontab files are stored in the /var/spool/cron/crontabs directory, where each file is named after the username of the owner. These files are not meant to be edited directly, but rather through the crontab command. The other options are either incorrect or non-existent locations for user crontab files. Reference:
Where is the user crontab stored?
crontab running as a specific user

Which TWO statements about crontab are true?
- A. Every user may have their own crontab.
- B. The cron daemon reloads crontab files automatically when necessary.
- C. Changing a crontab requires a reload/restart of the cron daemon.
- D. hourly is the same as "0 * * * *".
- E. A cron daemon must run for each existing crontab.
Answer: A,B
Explanation:
A). It is true that every user may have their own crontab. This allows individual users to schedule tasks to be run at specific times without requiring administrative privileges1.
C). The cron daemon does indeed reload crontab files automatically when necessary. This means that after editing a crontab file, there is no need to manually restart the cron service for the changes to take effect1.

NEW QUESTION # 51
Which of the following commands connects to the remote host example.com which has OpenSSH listening on TCP port 2222? (Choose TWO correct answers.)
- A. ssh -p 2222 example.com
- B. ssh -o GatewayPort=2222 example.com
- C. ssh example.com:2222
- D. ssh --port 2222 example.com
- E. ssh -o Port=2222 example.com
Answer: A,E
Explanation:
T The ssh command is used to connect to a remote host using the Secure Shell (SSH) protocol, which provides encrypted and authenticated communication. The ssh command has the following syntax:
ssh [options] [user@]hostname [command]
The options can modify the behavior of the ssh command, such as specifying the port number, the identity file, the cipher, the compression, and the timeout. The user@hostname specifies the username and the hostname of the remote host to connect to. The command is an optional argument that specifies the command to execute on the remote host.
To connect to the remote host example.com which has OpenSSH listening on TCP port 2222, two possible options are:
B . ssh -p 2222 example.com: This option uses the -p flag to specify the port number of the remote host. The -p flag is a shortcut for the Port option, which can also be used with the -o flag.
C . ssh -o Port=2222 example.com: This option uses the -o flag to specify a configuration option for the ssh command. The -o flag can be followed by any option that is valid in the ssh_config file, such as Port, IdentityFile, Cipher, Compression, and ConnectTimeout. The Port option sets the port number of the remote host.
The other options in the question are not correct for this task. The --port option is not a valid option for the ssh command. The GatewayPort option is used to specify whether remote hosts are allowed to connect to local forwarded ports. The example.com:2222 syntax is not valid for the ssh command.

NEW QUESTION # 52
Which of the following is a legacy program provided by CUPS for sending files to the printer queues on the command line?
- A. lpd
- B. lpq
- C. lpr
- D. lpp
Answer: C
Explanation:
The lpr command is a legacy program provided by CUPS for sending files to the printer queues on the command line. It is one of the Berkeley (lpr) printing commands that CUPS supports for compatibility with other Unix-like systems. The lpr command accepts one or more filenames asarguments and sends them to the default or specified printer. It also supports several options to control the printing process, such as the number of copies, the page size, the orientation, and the priority. The lpr command is equivalent to the lp command, which is one of the System V (lp) printing commands that CUPS also supports. However, the lp command has more options and features than the lpr command, and is recommended for use with CUPS. References:

NEW QUESTION # 53
Which of the following commands shows the current color depth of the X Server?
- A. cat /etc/X11
- B. xcd
- C. xcdepth
- D. xcolordepth
- E. xwininfo
Answer: E
Explanation:
The command that can be used to show the current color depth of the X Server is xwininfo. xwininfo is a command-line tool that provides information about X windows. When executed, it opens a small window and waits for the user to select a window by clicking on it. Then, it displays various characteristics about the window in question, such as its geometry, position, size, depth, class, name, id, and more. The depth value indicates the number of bits per pixel used to represent the colors of the window. xwininfo is part of the X Window System, which is a graphical user interface system for Unix-like operating systems. xwininfo can be useful for debugging, testing, or scripting purposes.
The other options are incorrect because they are either invalid commands or do not show the color depth of the X Server:
xcd is not a valid command in Linux. It may be confused with cd, which is used to change the current working directory.
xcdepth is not a valid command in Linux. It may be confused with xrandr, which is used to change the screen resolution and orientation.
xcolordepth is not a valid command in Linux. It may be confused with xcalib, which is used to load, alter, and query the color profile of the X display.
cat /etc/X11 is not a command, but a directory. cat is used to concatenate files and print them to the standard output. /etc/X11 is a directory that contains configuration files for the X Window System. However, these files do not necessarily show the current color depth of the X Server, as it may be overridden by other settings or options. Reference:

https://x.org/releases/X11R7.5/doc/man/man5/xorg.conf.5.html

This command updates the MTA's aliases database and makes the changes effective. It is equivalent to the commands sendmail -bi or sendmail -I12. The newaliases command should be run after making modifications to the /etc/aliases file, which contains the email aliases for the system3.
NEW QUESTION # 57
Which command is used to add an empty group to the system? (Specify ONLY the command without any path or parameters.)
Answer:
Explanation:
groupaddusrsbingroupadd
Explanation:
The groupadd command is used to add an empty group to the system. It takes the name of the group as an argument and creates an entry for it in the /etc/group file. The groupadd command also assigns a unique group ID (GID) to the new group. The groupadd command can take various options to specify the GID, the password, and other attributes of the new group. For example, groupadd -g 1000 mygroup will create a new group named mygroup with a GID of 1000. Reference:

To exclude all log messages of a given logging facility, you should use a logging priority of _____ .
Answer:
Explanation:
none
Explanation:
To exclude all log messages of a given logging facility, you should use a logging priority of none. This means that no messages from that facility will be logged, regardless of their severity level. For example, if you want to exclude all messages from the local0 facility, you can use local0.none in your syslog configuration file. This will prevent any messages from local0 from being written to any log file or destination that matches that selector12. The logging priority of none is part of the LPI's multi-level Linux professional certification program, and it is covered in the topic 106.1 System logging of the exam 102 objectives3. Reference: 1: logging - exclude syslog facility from all others - Server Fault 2: rsyslog.conf(5) - Linux manual page - man7.org 3: Exam 102 Objectives

NEW QUESTION # 62
What output is produced by the following command sequence?
echo '1 2 3 4 5 6' | while read a b c; do
echo result $c $b $a;
done
- A. result: 3 4 5 6 2 1
- B. result: 1 2 3 4 5 6
- C. result: 6 5 4
- D. result: 6 5 4 3 2 1
- E. result: 3 2 1
Answer: C
Explanation:
The command sequence uses a while loop to read the input from the echo command and assign the values to the variables a, b, and c. The read command reads one line of input at a time and splits it into words according to the IFS variable, which is a space by default. The first word is assigned to the first variable, the second word to the second variable, and so on. If there are more words than variables, the remaining words are assigned to the last variable. In this case, the input line has six words, so the read command assigns 1 to a, 2 to b, and 3 4 5
6 to c. Then, the echo command prints the result with the variables in reverse order, i.e., $c $b $a. Therefore, the output is result: 6 5 4 3 2 1. However, the answer choices only show the first three words of the output, so the correct answer is A. result: 6 5 4.

NEW QUESTION # 64
Which configuration file would be edited to change default options for the OpenSSH server?
- A. /etc/ssh/server
- B. /etc/ssh/ssh_config
- C. /etc/ssh/sshd_config
- D. /etc/ssh/ssh_server
- E. /etc/ssh/ssh
Answer: C
Explanation:
The configuration file for the OpenSSH server is called sshd_config. It is typically located in /etc/ssh on most
*NIX systems, but is /etc/sshd_config in the case of MacOS X and perhaps other systems. OpenSSH has two different sets of configuration files: one for client programs (ssh, scp, and sftp) and one for the server daemon (sshd). System-wide SSH configuration information is stored in the /etc/ssh/ directory1. References: 1: Where is the configuration file for OpenSSH server?
NEW QUESTION # 65
Which commands can you use to change a user's account aging information? (Choose THREE correct answers.)
- A. usermod
- B. passwd
- C. chattr
- D. chsh
- E. chage
Answer: A,B,E
Explanation:
The commands that can be used to change a user's account aging information are:
usermod: this command can modify various user account properties, including the password expiration date, the account expiration date, the minimum and maximum password age, the password warning period, and the password inactivity period. To use this command, you need to specify the option and the value for the property you want to change, followed by the username. For example, to set the password expiration date for the user test to February 11, 2022, you can run:
usermod -e 2022-02-11 test
To view the current account aging information for a user, you can use the -l option with the usermod command. For example, to view the information for the user test, you can run:
usermod -l test
passwd: this command can change the password of a user account, as well as some password aging options. To use this command, you need to specify the username and the option for the property you want to change. For example, to change the password of the user test, you can run:
passwd test
To set the maximum password age for the user test to 90 days, you can run:
passwd -x 90 test
To view the current password aging information for a user, you can use the -S option with the passwd command. For example, to view the information for the user test, you can run:
passwd -S test
chage: this command can change the user password expiry and aging information, such as the password expiration date, the account expiration date, the minimum and maximum password age, the password warning period, and the password inactivity period. To use this command, you need to specify the option and the value for the property you want to change, followed by the username. For example, to set the account expiration date for the user test to February 11, 2022, you can run:
chage -E 2022-02-11 test
To view the current account aging information for a user, you can use the -l option with the chage command. For example, to view the information for the user test, you can run:
chage -l test
The other options are incorrect because:
chattr: this command can change the file attributes on a Linux file system, such as making a file immutable, append-only, or undeletable. It has nothing to do with user account aging information.
chsh: this command can change the login shell of a user account, such as bash, zsh, or ksh. It has nothing to do with user account aging information.

The system's timezone may be set by linking /etc/localtime to an appropriate file in which directory? (Provide the full path to the directory, without any country information)
Answer:
Explanation:
usrsharezoneinfo
Explanation:
The /usr/share/zoneinfo directory contains the binary time zone files that are used by the system to determine the local time for any region. The files are organized in subdirectories by continent, country, or ocean. Some files represent the standard time zones, while others may have historical or political variations. To set the system's timezone, one can create a symbolic link from /etc/localtime to the appropriate file in the /usr/share/zoneinfo directory. For example, to set the timezone to America/New_York, one can use the command sudo ln -sf /usr/share/zoneinfo/America/New_York /etc/localtime. Alternatively, one can use the timedatectl command to set the timezone without creating the link manually. Reference:

NEW QUESTION # 69
In an xinetd configuration file, which attribute specifies the network address that will be used to provide the service?
Answer:
Explanation:
bind, interface
Explanation:
The bind attribute in an xinetd configuration file specifies the network address that will be used to provide the service. It can be either an IP address or a hostname. If the bindattribute is not specified, xinetd will listen on all available addresses on the system. The bind attribute can be used to restrict the service to a specific interface or network. For example, bind = 192.168.1.100 will only allow the service to be accessed from the
192.168.1.0/24 network. The bind attribute can also be used to provide different configurations for the same service on different addresses. For example, one can have two telnet configuration files, one with bind =
192.168.1.100 and another with bind = 192.168.2.100, to offer different access rules or options for the telnet service on each address.
