Which feature of Windows enhances security by encrypting the entire drive, requiring authentication at startup?
File-level encryption
System restore
Full disk encryption
Data backup options
Full disk encryption - This is correct. Full disk encryption, provided by features like BitLocker in Windows, enhances security by encrypting the entire drive. It protects data by requiring authentication (such as a password, PIN, or hardware key) at startup before the drive can be accessed, ensuring that unauthorized users cannot access the data even if the drive is removed from the computer.
File-level encryption - File-level encryption protects individual files or folders rather than the entire drive. It allows selective encryption but does not secure the whole disk as full disk encryption does.
System restore - System restore is a feature that allows users to revert their computer to a previous state, often to fix issues. It does not involve encryption or enhance security.
Data backup options - Data backup options focus on creating copies of data to prevent loss. While backups are essential for data recovery, they do not enhance security through encryption.
