Question 61 · 300 in bank
Joe, a user, is unable to log in to the Linux system. Given the following output:
Which of the following commands would resolve the issue?
Show answer
Answer: A
Explanation
The command usermod -s /bin/bash joe changes the login shell of the user named "joe" to "/bin/bash". Explanation: usermod is a command in Linux used to modify user account details. -s /bin/bash is an option used with the usermod command to specify the new login shell for the user. In this case, the login shell is changed to "/bin/bash". "joe" is the username of the user whose account is being modified. Changing the login shell of a user can be useful in cases where a different shell is required for a particular user. In this case, the user "joe" will now use the Bash shell as their default shell when they log in.

Question 66 · 300 in bank
Which of the following commands is used to configure the default permissions for new files?
Show answer
Answer: C
Explanation
C. umask Explanation: umask is a command in Linux that sets the default file permissions for newly created files and directories. The default permissions are calculated by subtracting the umask value from 777 for files and 666 for directories. The result is the default permission for each bit (r, w, and x). For example, a umask value of 022 would result in file permissions of 644 (666 - 022) and directory permissions of 755 (777 - 022). Option A (setenforce) is used to set the enforcement mode of SELinux, the security module in Linux. It is not used to configure the default permissions for new files. Option B (sudo) is used to run commands with administrative privileges. It is not used to configure the default permissions for new files. Option D (chmod) is used to change the permissions of existing files and directories, but not to configure the default permissions for new files.

The -w option specifies that the change should be written to the running system and not just displayed.
