When connecting a Bluetooth device like a hands-free car system, using a PIN code adds a layer of security.
The PIN code must be entered or confirmed during the pairing process to ensure that the connection is authorized and secure.
D: PIN code: Provides an additional security measure during Bluetooth pairing to prevent unauthorized access.
Why the other options are incorrect:
A: BitLocker: BitLocker is a drive encryption feature used to secure data on hard drives, not for securing Bluetooth connections.
B: Biometrics: Biometrics refers to authentication using physical traits like fingerprints, which are not typically used for Bluetooth connections.
C: TPM: Trusted Platform Module (TPM) is a hardware security feature used for encryption and secure boot processes, not for Bluetooth pairing.
This falls under the Mobile Devices and Security domain in the CompTIA A+ Core 1 exam.
