Q

How can BitLocker be implemented on Windows systems that don’t have a TPM chip on the motherboard?

A

If a computer doesn’t have a TPM, saving a startup key on a removable drive, such as a USB flash drive, becomes mandatory when enabling BitLocker.

Q

Which of the following security solutions would prevent you from reading a file that you did not create?

a)EFS
b)BitLocker
c)IPSec
d)VPN

A

a)EFS

18
Q

Remote Desktop Protocol (RDP)

A

is used by Windows Terminal Services-based applications, including Remote Desktop.

19
Q

FTP (File Transfer Protocol)

A

is used for transferring files. It does not establish a secure connection.

20
Q

WPA (Wi-fi Protected Access) and WEP (Wired Equivalent Privacy)

A

are protocols used to secure wireless communications.

21
Q

Encrypting File Server (EFS)

A

is a Windows feature that can encrypt a single file or multiple files and folders.

22
Q

BitLocker

A

is a Windows feature that encrypts an entire disk

23
Q

.

Single sign-on (SSO)

A

permits a user to employ the same credentials to automatically log in to other sites and services. SSO is not used for encryption.

24
Q

An administrative share

A

is used by administrators to access system drives. It is not used for encryption.

25
Q

BitLocker is designed to protect files against offline access only.
True or False

A

True

26
Q

BitLocker is not designed to protect file against online access. This is the purview of EFS.
True or False

A

True

27
Q

BitLocker is not designed to encrypt individual files. BitLocker encrypts the entire hard drive.
True or False

A

True

28
Q

BitLocker is not designed for use on the Home edition of Windows 10 or later. BitLocker is only available on the Ultimate and Enterprise editions.
True or False

A

True

29
Q

BitLocker is not designed for use on the Home edition of Windows 10 or later. BitLocker is only available on the Ultimate and Enterprise editions.

A

True

30
Q

BitLocker To Go

A

provides drive encryption for removable data drives, including USB flash drives. You can use BitLocker To Go to encrypt the data on a flash drive. The only way to decrypt the data on the flash drive is through the recovery password. Using BitLocker To Go and not sharing the recovery password would keep the data on the flash drive secure.

31
Q

BitLocker

A

is a drive encryption program that is designed to be used with NTFS files on your hard drive, not on non-NTFS removeable devices. Most USB flash drives use FAT32 or exFAT storage.

32
Q

Files that are encrypted with ____________ , lose their encryption when they are copied to a USB flash drive, which is commonly formatted with FAT32 or exFAT.

A

EFS, or Encrypting File System

33
Q

Microsoft Defender

A

is an antivirus program for Windows that does not encrypt files on a flash drive.

34
Q

A Trusted Platform Module (TPM)

A

is a special hardware chip included on a computer’s motherboard that contains software (within the firmware) that generates and stores cryptographic keys.

35
Q

BitLocker

A

is an encryption program, not a hardware chip.

36
Q

A USB device

A

is what saves the BitLocker key on a system that does not have a TPM chip.

37
Q

The TPM chip must be enabled in the BIOS/UEFI, but the BIOS/UEFI is not the chip itself. True or False

A

True

38
Q

BitLocker with TPM

A

BitLocker checks the integrity of the early boot components and the boot configuration data by using the Trusted Platform Module (TPM) to ensure that the data is accessible only when the computer’s boot components appear unaltered. Also, the encrypted disk must be in the same computer it was in when it was originally encrypted with BitLocker. This means that if someone were to obtain that hard drive and put it in a different computer, they wouldn’t be able to access the data on that drive. The data stays encrypted.

39
Q

BitLocker To Go

A

While BitLocker is designed to protect system hard drives, BitLocker To Go is designed to protect removeable storage devices, such as flash drives.

40
Q

Microsoft Defender

A

is an antivirus program designed to protect the Windows system from malware. This program would have no effect on preventing access to a stolen hard drive’s data.

41
Q

Windows Security

A

is a program that scans for security threats, malware, and viruses. It would have no effect on preventing access to a stolen hard drive’s data.
