The correct technique that enables an IT administrator to erase data from a lost mobile device is the remote wipe. This process allows the administrator to send a command over the network to the lost device, triggering it to delete all data stored on the device, thus preventing unauthorized access to sensitive information.

Remote wiping is particularly valuable in scenarios where the device is lost or stolen, as it provides a means to protect corporate data and maintain compliance with data protection regulations. This capability is often built into mobile device management (MDM) solutions, making it a crucial security measure for organizations that handle sensitive information on mobile devices.

In contrast, a factory reset typically refers to restoring the device to its original system state, which may not always be remotely initiated and may require physical access to the device. Access control focuses on restricting who can access certain information or systems, and data encryption involves securing data to prevent unauthorized access, but it does not directly address the issue of erasing data on a lost device.
