A systems administrator needs to encrypt all data on employee laptops. Which of the following encryption levels should be implemented?

Full disk encryption (FDE) is the most appropriate choice for encrypting all data on employee laptops because it encrypts the entire storage device, including the operating system, applications, and all user data. This ensures that if a laptop is lost or stolen, all information on it remains protected. Volume encryption encrypts a logical volume, which might not cover the entire disk if there are multiple volumes or unallocated space. Partition encryption encrypts a specific partition, leaving other partitions or the boot sector vulnerable. File encryption only encrypts individual files, which is insufficient for comprehensive laptop security as it leaves the operating system and other unencrypted files exposed.
