Create user app01 and create its home directory at /srv/home/app01.
Which command is appropriate?
× Incorrect
Use -d to set the home path and -m to create that directory. Registration and physical creation are separate options.
Detailed explanation
Incorrect
useradd -d /srv/home/app01 app01Incorrect. -d registers the path but without -m creation depends on defaults.
Correct
useradd -m -d /srv/home/app01 app01Correct. It specifies the path and creates the home directory.
Incorrect
useradd -m -s /srv/home/app01 app01Incorrect. -s sets the login shell.
Incorrect
useradd -M -d /srv/home/app01 app01Incorrect. -M explicitly disables creation.
