NEW QUESTION # 20
Given the following excerpt of the sudo configuration:
jane ANY=NOPASSWD: /bin/kill, /bin/id, PASSWD: /sbin/fdisk
Which of the following statements are true? (Choose three.)
- A. Jane can run /bin/kill without specifying a password.
- B. Jane can run /sbin/fdisk after specifying her password.
- C. Jane can run /bin/id without specifying her password.
- D. Jane can run /bin/id only after specifying her password.
- E. Jane can run /sbin/fdisk after specifying root's password.
Answer: A,B,C
Explanation:
The sudo configuration file (/etc/sudoers) defines the rules for granting privileges to users or groups to execute commands as another user, usually the superuser or root. The format of the sudo configuration file is as follows:
user_list host_list=effective_user_list tag_list command_list
The user_list specifies the users who can run the commands, the host_list specifies the hosts where the commands can be run, the effective_user_list specifies the user as whom the commands can be run, the tag_list specifies some options for the commands, and the command_list specifies the commands that can be run.
In this case, the user_list is jane, the host_list is ANY (meaning any host), the effective_user_list is not specified (meaning root by default), the tag_list is NOPASSWD or PASSWD (meaning whether a password is required or not), and the command_list is /bin/kill, /bin/id, or /sbin/fdisk.
Therefore, the sudo configuration file allows jane to run /bin/kill, /bin/id, or /sbin/fdisk as root on any host, but with different password requirements. Specifically:
* Jane can run /bin/kill without specifying a password, because the tag_list is NOPASSWD for this command. This means that jane can execute sudo /bin/kill and the command will run as root without asking for any password. This makes option D true.
* Jane can run /bin/id without specifying a password, because the tag_list is also NOPASSWD for this command. This means that jane can execute sudo /bin/id and the command will run as root without asking for any password. This makes option E true.
* Jane can run /sbin/fdisk after specifying her password, because the tag_list is PASSWD for this command. This means that jane can execute sudo /sbin/fdisk and the command will ask for jane's password before running as root. This makes option C true.
The other options are false because:
* Jane cannot run /bin/id only after specifying her password, because the tag_list is NOPASSWD for this command. This makes option A false.
* Jane cannot run /sbin/fdisk after specifying root's password, because the password that is required is jane's password, not root's password. This makes option B false.

NEW QUESTION # 26
To prevent a specific user from scheduling tasks with at, what should the administrator do?
- A. Add the specific user to nojobs group.
- B. Add the specific user to [deny] section in the /etc/atd.conf file.
- C. Add the specific user to /etc/at.deny file.
- D. Add the specific user to /etc/at.allow file.
- E. Run the following: atd --deny [user].
Answer: C
Explanation:
The /etc/at.deny file is a file that contains a list of users who are not allowed to use the at command to schedule jobs. If the file exists, any user who is not in the /etc/at.allow file and is in the /etc/at.deny file will be denied access to the at command. To prevent a specific user from scheduling tasks with at, the administrator can simply add the user's name to the /etc/at.deny file. For example, to prevent the user bob from using the at command, the administrator can use the following command:
echo "bob" | sudo tee -a /etc/at.deny
The other options are not correct. The /etc/at.allow file is a file that contains a list of users who are allowed to use the at command. Adding a user to this file will not prevent them from scheduling tasks with at. The
/etc/atd.conf file is a configuration file for the at daemon, which does not have a [deny] section. Adding a user to this file will not affect their access to the at command. The nojobs group is not a predefined group in Linux, and adding a user to this groupwill not prevent them from scheduling tasks with at. The atd command does not have a --deny option, and running this command will not prevent a user from scheduling tasks with at.

Which commands can be used to change a user's account aging information? (Choose THREE correct answers.)
- A. chage
- B. passwd
- C. usermod
- D. chsh
- E. chattr
Answer: A,B,C
Explanation:
The usermod, passwd, and chage commands can be used to change a user's account aging information. These commands can modify the password expiry date, the last password change date, the minimum and maximum number of days between password changes, the number of days of warning before password expiration, and the number of days of inactivity after password expiration. The usermod command is mainly used for modifying a user account, but it also has options for changing the password expiry and aging information, such as -e, -f, -p, and -L1. The passwd command is mainly used for changing the user password, but it also has options for changing the password expiry and aging information, such as -e, -i, -n, -w, and -x2. The chagecommand is specifically used for changing the user password expiry and aging information, and it has options such as -d, -E, -I, -m, -M, and -W3.
The other options, chattr and chsh, are not related to changing the user's account aging information. The chattr command is used to change the file attributes on a Linux file system4. The chsh command is used to change the user's login shell5.

NEW QUESTION # 37
After issuing:
function myfunction { echo $1 $2 ; }
in Bash, which output does:
myfunction A B C
Produce?
- A. A B C
- B. A C
- C. B C
- D. C B A
- E. A B
Answer: E
Explanation:
In Bash, a function is a block of code that can be invoked by its name. A function can take arguments, which are passed to the function as positional parameters. The $1 variable refers to the first argument, $2 to the second argument, and so on. The function can access the number of arguments passed to it by using the $# variable. In this case, thefunction myfunction simply echoes the first and second arguments to the standard output. Therefore, when the command myfunction A B C is executed, the output is A B, since the third argument C is ignored by the function. References:
