CompTIA Linux+ XK0-006 (V8) Practice Question

A system administrator needs to allow users in the 'developers' group to restart a specific systemd service, dev-app.service, without entering a password. The administrator wants to use a centralized, fine-grained authorization framework instead of granting broad sudo privileges. Which of the following approaches correctly implements this requirement using Polkit?

  • Create a .pkla file in /etc/polkit-1/localauthority/50-local.d/ specifying the org.freedesktop.systemd1.manage-units action and the 'developers' group, with ResultActive=yes.

  • Create a JavaScript rule in /etc/polkit-1/rules.d/ that grants permission for the org.freedesktop.systemd1.manage-units action to the 'developers' group when the unit is dev-app.service, returning polkit.Result.YES.

  • Use visudo to add the line %developers ALL=(ALL) NOPASSWD: /usr/bin/systemctl restart dev-app.service to the /etc/sudoers file.

  • Configure a new service file in /etc/pam.d/ that uses the pam_succeed_if.so module to grant access to systemctl for members of the 'developers' group.
