CompTIA A+ Certification Core 2 (220-1102) - Multifactor Authentication (MFA)

The video tutorial explains multi-factor authentication (MFA) and its importance in enhancing security. It covers four types of MFA: 'something you know' (e.g., passwords), 'something you have' (e.g., SMS codes, authenticator apps), 'something you are' (e.g., biometrics like fingerprints and facial recognition), and 'somewhere you are' (e.g., GPS-based verification). The tutorial also highlights Windows 11's sign-in options, including facial recognition and fingerprint scanning, emphasizing the need for multiple authentication methods to protect systems and data.

What is a common vulnerability of using only 'something you know' as a form of authentication?

• It can be shared or hacked.

• It can be easily forgotten.

• It requires special hardware.

• It is too expensive to implement.

Which of the following is an example of 'something you have' in two-factor authentication?

• Facial recognition

• An SMS code

• A fingerprint scanner

• A password

What type of authentication involves using biometrics like fingerprint scanners?

• Somewhere you are

• Something you have

• Something you know

• Something you are

In which environments is 'somewhere you are' authentication primarily used?

• Public Wi-Fi networks

• Corporate or critical infrastructure environments

• Home networks

• Personal devices

What is a key feature of Windows Hello in Windows 11?

• It does not support biometric authentication.

• It only supports password login.

• It allows for facial recognition setup.

• It requires a physical key for login.
