A security analyst is troubleshooting a scenario in which an operator should only be allowed to reboot remote hosts but not perform other activities. The analyst inspects the following portions of different configuration files:
Configuration file 1:
Operator ALL=/sbin/reboot -
Configuration file 2:
Command=`/sbin/shutdown now`, no-x11-forwarding, no-pty, ssh-dss
Configuration file 3:
Operator1000:/home/operator:/bin/bash
Which of the following explains why an intended operator cannot perform the intended action?
A. The sudoers file is locked down to an incorrect command
B. SSH command shell restrictions are misconfigured
C. The passwd file is misconfigured
D. The SSH command is not allowing a pty session
