Which of the following best describes BitLocker?

BitLocker is a full disk encryption feature integrated into certain editions of the Windows operating system, which effectively encrypts the entire drive on which the operating system is installed, as well as any additional data drives. This technology uses the Advanced Encryption Standard (AES) algorithm to secure data against unauthorized access and protects the entire volume from tampering or theft.

By encrypting the disk at the full volume level, BitLocker ensures that all files and folders are encrypted, providing a robust security measure that safeguards sensitive information. It also integrates with the computer's trusted platform module (TPM) hardware, which enhances security by storing encryption keys and providing a secure boot process.

This approach differs from other forms of encryption or backup solutions. Unlike a hardware-based tool, which may involve dedicated hardware components, or a software solution focused solely on portable drives, BitLocker encompasses a comprehensive disk encryption process for the Windows operating system. A backup solution focuses on recovering lost data, while BitLocker specifically protects data by preventing unauthorized access, rather than providing a restoration mechanism.
