    • Floppy drive

    • Monitor

    • Keyboard

    Correct Answer(s)
    A. SMPS
    A. Monitor
    Explanation
    SMPS (Switched Mode Power Supply) and Monitor can cause great harm to one's life with lethal electric shocks. SMPS is responsible for converting the AC power from the wall outlet to the DC power required by the computer components. If not handled properly, it can deliver high voltage electric shocks. Similarly, monitors can store high levels of electrical charge which can be dangerous if mishandled. Floppy drives and keyboards, on the other hand, do not possess the same level of electrical risk.

    Correct Answer
    A. It involves two or more methods as part of the authentication process
    Explanation
    The correct answer is "it involves two or more methods as part of the authentication process". This means that multi-factor authentication requires the use of multiple methods or factors to verify the identity of a user. These factors can include something the user knows (such as a password), something the user has (such as a smart card), or something the user is (such as a fingerprint). By combining multiple factors, multi-factor authentication provides an extra layer of security compared to single-factor authentication methods.
