A sign-in requires both a password and a PIN. How many distinct factor categories does this combination use?

  1. A

    Two factors, because the password and PIN are separate credentials

  2. B

    One factor, because both are things the user knows

  3. C

    Two factors, because a PIN is always a possession factor

  4. D

    No factors, because neither credential identifies an account

A company has verified an employee's identity. Which process determines whether that employee may open a particular project folder?

  1. A

    Authentication, because it determines which files the user may open

  2. B

    Authorization, because it determines what an authenticated identity may access

  3. C

    Multi-factor authentication, because the user is opening a protected folder

  4. D

    Enrollment, because a user has requested access to a resource

A device uses a fingerprint to unlock a cryptographic key before connecting to a service. Which description best fits this design?

  1. A

    The fingerprint is sent to the network as the user's password

  2. B

    The fingerprint replaces the need for any device-held credential

  3. C

    The fingerprint locally unlocks a device-held key used to authenticate

An organization wants stronger protection against an impostor site capturing and reusing sign-in proof. Which method best meets that goal?

  1. A

    A manually entered code, because a short-lived code cannot be relayed

  2. B

    A properly implemented cryptographic authenticator, because it can bind authentication to the legitimate service or session

  3. C

    A password, because using a unique password prevents phishing

  4. D

    A push prompt, because an approval notification cannot be targeted

    Store passwords using salted, purpose-built password hashing rather than readable text

  2. B

    Monitor authentication logs for unusual failures, locations, devices, and repeated MFA prompts

  4. D

    A password combined with a PIN

A user receives a push-approval request while not trying to sign in. What is the safest response?

  1. A

    Approve the prompt if it arrives on a registered device, since registration confirms the request is legitimate.

  2. B

    Approve one prompt but ignore any later prompts, since only repeated requests indicate risk.

An organization uses certificate-based authentication for enterprise Wi-Fi. Why should client devices validate the network’s server certificate?

  1. A

    To help ensure the device is connecting to the legitimate network rather than sending credentials to a rogue network.

  2. B

    To let the device skip authentication whenever a familiar network name is detected.

  3. C

    To ensure that every Wi-Fi user receives broad access after presenting any certificate.
