Why each option

Resetting a password on a Cisco TelePresence EX Series endpoint running TC7 requires a specific physical button sequence while the device is powered down.

AUse SSH to access the device and use the username "cisco" and the password "TANDBERG."

SSH access with default credentials (cisco/TANDBERG) is a factory-default login method, not a password recovery procedure for a locked device.

BHold down the mute key on the touch display for 25 seconds and reset the password using the

Holding the mute key on the touch display for 25 seconds is not a documented reset procedure for TC7 software on EX Series endpoints.

CWhen the device is powered down, hold down the power button until the power light blinks twice,Correct

On TC7 software, the hardware-based password reset procedure requires the device to be fully powered off, then holding the power button until the power LED blinks twice. This triggers the endpoint to boot into a recovery mode that allows the administrator password to be reset without needing prior credentials.

DTap the power button four times within ten seconds and then use Telnet to connect to the device

Tapping the power button four times and using Telnet is not a valid recovery procedure; Telnet is also disabled by default on TC7 endpoints.

ETap the power button five times while the device is powered off and when it boots, use Telnet to

Tapping the power button five times while powered off and using Telnet does not match the documented TC7 recovery sequence, and Telnet is not the correct access method for this procedure.
