Question

A user has a file that contains sensitive data.

Which of the following can be used to encrypt a single file?
O EFSO BitLockerO Trusted Platform Module (TPM)O Bitlocker To Go

Answer 1

Of the options listed, EFS (Encrypting File System) and BitLocker To Go can be used to encrypt a single file.

EFS is a built-in Windows feature that can be used to encrypt individual files and folders on an NTFS file system. It provides file-level encryption, allowing you to encrypt a single file. However, note that EFS is not available in all editions of Windows.

BitLocker To Go is another Windows feature that can be used to encrypt a single file. It is designed for removable storage devices such as USB drives and external hard drives. With BitLocker To Go, you can encrypt individual files on the device.

BitLocker and TPM are not designed to encrypt single files, but rather to encrypt entire volumes or disks. BitLocker can be used to encrypt entire hard drives, while TPM (Trusted Platform Module) is a hardware chip that provides secure storage of encryption keys and can be used in combination with BitLocker to protect the data on the disk.

So in summary, EFS and BitLocker To Go can be used to encrypt a single file, while BitLocker and TPM are not suitable for this purpose.
