CompTIA Linux+ XK0-006 (V8) Practice Question

While troubleshooting privilege escalation on a Fedora workstation that is joined to an Active Directory (AD) domain through SSSD, you observe the following behavior: when an unprivileged user opens GNOME Settings and attempts to set the system clock, a window appears requesting the user's password. After the password is entered, the time change succeeds.

Which pair of components is responsible for (1) showing that password prompt and (2) validating the password against the AD domain?

  • (1) Polkit authentication agent, (2) PAM stack that calls pam_sss/SSSD

  • (1) Linux-PAM conversation dialog, (2) Kerberos client libraries directly

  • (1) GNOME Shell built-in prompt, (2) polkitd local authority backend

  • (1) SSSD cache responder, (2) libvirt via pam_unix.so
