The answer is BitLocker To Go, which is the correct Windows feature to encrypt a USB flash drive for use on both Windows 10 and Windows 11 devices. This tool, available in the Pro and Enterprise editions of Windows, applies full-disk encryption to removable drives, ensuring that if the drive is lost, its data remains unreadable on any other computer without the password or recovery key. On the CompTIA A+ Core 2 220-1202 exam, this question tests your knowledge of Windows security features and their appropriate use cases, often appearing as a scenario where a user needs portable data protection across different Windows versions. A common trap is confusing BitLocker To Go with standard BitLocker, which only encrypts internal drives, or with EFS, which encrypts individual files. Remember the memory tip: “To Go” means it goes with you on a removable drive, while standard BitLocker stays inside the computer.
