Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Time-based One-Time Password (TOTP) authenticator apps (e.g., Google Authenticator)

    Why this is correct

    TOTP codes generated by authenticator apps are natively supported.

  • Biometric retina scans processed by local BIOS firmware

    Why it's wrong here

    Retina scans handled solely by local BIOS are not natively integrated as a standard Google Workspace network 2SV mechanism.

  • Automatic voice call verification through landline pulse dialing tones

    Why it's wrong here

    Pulse dialing tone verification is not a supported Google 2SV authentication method.

  • Google Prompts sent to trusted mobile devices

    Why this is correct

    Google Prompts allow users to tap 'Yes, it's me' on their phone to verify sign-in.

  • Security keys (FIDO2 / U2F hardware keys like Titan keys)

    Why this is correct

    Hardware security keys provide phishing-resistant authentication.
