Which of the following commands will accomplish this task?

A Linux administrator is tasked with adding users to the system. However, the administrator wants to ensure the users’ access will be disabled once the project is over. The expiration date should be 2021-09-30.

Which of the following commands will accomplish this task?
A . sudo useradd -e 2021-09-30 Project_user
B . sudo useradd -c 2021-09-30 Project_user
C . sudo modinfo -F 2021-09-30 Project_uses
D . sudo useradd -m -d 2021-09-30 Project_user

Answer: A

Explanation:

The command that will accomplish this task is sudo useradd -e 2021-09-30 Project_user. This command will create a new user account named Project_user with an expiration date of 2021-09-30. The -e option of useradd specifies the date on which the user account will be disabled in YYYY-MM-DD format.

The other options are not correct commands for creating a user account with an expiration date. The sudo useradd -c 2021-09-30 Project_user command will create a new user account named Project_user with a comment of 2021-09-30. The -c option of useradd specifies a comment or description for the user account, not an expiration date. The sudo modinfo -F 2021-09-30 Project_user command is invalid because modinfo is not a command for managing user accounts, but a command for displaying information about kernel modules. The -F option of modinfo specifies a field name to show, not an expiration date. The sudo useradd -m -d 2021-09-30 Project_user command will create a new user account named Project_user with a home directory of 2021-09-30. The -m option of useradd specifies that the home directory should be created if it does not exist, and the -d option specifies the home directory name, not an expiration date.
