Which two video endpoints can you set back to factory reset by using physical button presses? (Choose two.)

The C40 is a rack-mounted codec unit that does not expose a physical factory reset button and requires a software-initiated reset instead.

The Cisco TelePresence EX90 is a personal video unit with a physical reset pinhole button that, when held during power-up, initiates a factory reset. This button is designed to be accessible on the device chassis without requiring rack removal or software access.

The C60 is a rack-mounted codec without an accessible physical reset button, requiring administrative access via web interface or CLI to perform a factory reset.

The Cisco TelePresence SX20 also has a physical reset button on its chassis that can be pressed to restore the unit to factory defaults. Both the EX90 and SX20 share this physical accessibility as personal and small-room endpoints.

The C90 is a high-end rack-mounted codec that does not provide a physical button for factory reset and requires software-based procedures to restore defaults.
