Which BitLocker encryption mode is selected in this lab?

• A. Legacy mode
• B. AES-CBC
• C. AES-XTS
• D. New encryption mode

Answer: (D)

BitLocker encryption modes determine how the encryption algorithm is applied to the disk. The older option uses AES in CBC mode ( Legacy), which is considered weaker for modern drives. The newer approach uses AES in XTS mode ( AES-XTS), designed for sector-based disk encryption and offering stronger protection against certain attacks. In this lab, the interface labels the newer option as “New encryption mode.” That label directly signals that the modern, XTS-based method is in use. So choosing the lab’s “New encryption mode” reflects selecting the AES-XTS-based configuration, which is why it’s the best answer here. The other terms correspond to older or different configurations—Legacy mode is AES-CBC, AES-CBC is the older CBC variant, and AES-XTS is the underlying newer algorithm but the lab specifically indicates the option with the label “New encryption mode.”
