The file on the hard disk and the data sent over the network will remain encrypted.B. The file on the hard disk and the data sent over the network will be decrypted andremain that way.C. The file on the hard disk will be decrypted, so EFS can send it encrypted over thenetwork.D. The file on the hard disk will remain encrypted, but data sent over the network willbe unencrypted.D.The file on the hard disk will remain encrypted, but data sent over the network willbe unencrypted. EFS only encrypts data on NTFS volumes.When data that isencrypted with EFS is sent over the network, it isn’t encrypted. For data to beencrypted during transmission, other methods like IPSec are needed.A, B, C. Answer A is incorrect because EFS only encrypts data on hard disks. It doesnot encrypt data transmitted over the network. Answer B is incorrect because when afile is transmitted over the network, the original file on the hard disk isn’t decryptedand left that way. EFS will keep the file on the hard disk encrypted, so others cannotaccess it. Answer C is incorrect, because EFS isn’t used for transmitting encrypted dataover the network.
