CompTIA Linux+ XK0-006 (V8) Practice Question

While hardening a server's SSH configuration, an administrator adds the following two lines to /etc/ssh/sshd_config and restarts sshd:

DenyUsers test*
AllowGroups admins

No other Allow/ Deny directives are present. Which statement correctly describes the effect of this change on future SSH login attempts?

  • Members of the admins group can always log in; the AllowGroups directive overrides the DenyUsers rule.

  • Any account whose username begins with test is denied SSH access even if that account belongs to the admins group.

  • Because both directives are present, sshd will fail to start until one of them is removed.

  • AllowGroups checks only a user's primary group; users who have admins solely as a supplementary group will still be rejected.
