CompTIA A+ Certification Core 1 (220-1101) - Encrypting Mass Storage

The video tutorial discusses the importance of encryption for protecting sensitive data on storage devices. It explains two main types of encryption: file-based and disk-based. The tutorial demonstrates how to use the Encrypting File System (EFS) on Windows for file-level encryption and BitLocker for disk-level encryption. It also covers setting up the Trusted Platform Module (TPM) for BitLocker and using BitLocker to Go for encrypting removable media.

Why is encryption important for portable devices?

• To increase the device's speed

• To enhance the device's display quality

• To protect sensitive data from unauthorized access

• To improve battery life

What is the main difference between file-based and disk-based encryption?

• File-based encryption requires a TPM module

• Disk-based encryption is only available on Linux

• File-based encryption encrypts individual files or folders, while disk-based encryption encrypts entire drives

• File-based encryption is faster than disk-based encryption

Which file system must be used to enable EFS on Windows?

• HFS+

• NTFS

• exFAT

• FAT32

What happens to an EFS-encrypted file when the user logs in?

• It remains encrypted and inaccessible

• It gets deleted

• It requires a password to decrypt

• It automatically decrypts and becomes available for use

What is the role of the Trusted Platform Module (TPM) in disk-based encryption?

• It stores encrypted files

• It speeds up the encryption process

• It provides a key necessary for unlocking encrypted drives

• It is used for file-based encryption only

Which tool is used for full disk encryption in Windows?

• File Vault

• BitLocker

• TrueCrypt

• EFS

What is BitLocker to Go designed for?

• Encrypting network drives

• Encrypting cloud storage

• Encrypting removable media like thumb drives

• Encrypting internal hard drives
