An administrator created a PIN for the ProxySG front panel, disabled the built-in administrative account and introduced policy-based admin authoritarian, and secured die serial port. After this was done, all the PINs, passwords and policy settings were lost. What options are available to regain access to the appliance?
(Choose all that apply)
(a) Return ProxySG appliance to Blue Coat to restore a default SGCS image
(b) Restore the factory settings by pressing and holding a reset button for 5 seconds, configure the appliance anew or restore its configuration from a backup
(c) Try out all 10000 combinations of PIN for the front panel until you find the right one
(d) Remove the hard disk from the ProxySG, connect it as an external SAT A disk to any
Windows or Linux computer; clear the admin entry in the /etc/ pssswd file on that disk. Put the hard disk back in ProxySG, start it up and reset the admin's password.
