Question 221 - XK0-005 discussion

The reason that the administrator is unable to perform the assigned duties is because the administrator is not a part of the correct group. This is option B.

Based on the image that you sent, I can see that the user comptia has a user ID and a group ID of 1000, and belongs to only one group, which is also comptia. However, the sudoers file, which defines the permissions for users to run commands as root or other users, does not include the comptia group in any of the entries. Therefore, the user comptia cannot use sudo to perform privileged functions on the system.

The other options are incorrect because:

A) The administrator needs a password reset.

This is not true, because the password aging information for the user comptia shows that the password was last changed on Oct 24, 2023, and it does not expire until Jan 22, 2024. There is no indication that the password is locked or expired.

C) The administrator did not update the sudo database.

This is not necessary, because the sudo database is automatically updated whenever the sudoers file is modified. There is no separate command to update the sudo database.

D) The administrator's credentials need to be more complex.

This is not relevant, because the complexity of the credentials does not affect the ability to use sudo. The sudoers file does not specify any password policy for the users or groups that are allowed to use sudo.
