Should this be A? It can restore default settings and lock encrypted data when necessary. Remote wipe is a security feature that allows administrators or device owners to remotely clear data off of a smart device, usually in the event it is lost or stolen. While it restores the device to default settings, locking encrypted data, it does not affect data that has been backed up elsewhere, such as to a desktop or via cloud computing. It's important to note that the remote wipe feature is primarily designed to protect data on the actual device. It does not enable the erasure and reformatting of SD cards (option B), which would require additional steps or settings. It also cannot delete data that has been backed up to a desktop (option C) or via cloud services (option D) since those backups exist outside of the control of the device's remote wipe capabilities.
