Google Cloud Professional Cloud Security Engineer — Question 290

You have noticed an increased number of phishing attacks across your enterprise user accounts. You want to implement the Google 2-Step Verification (2SV) option that uses a cryptographic signature to authenticate a user and verify the URL of the login page. Which Google 2SV option should you use?

Answer options

• A. Titan Security Keys
• B. Google prompt
• C. Google Authenticator app
• D. Cloud HSM keys

Correct answer: A

Explanation

The correct answer is A, Titan Security Keys, as they provide hardware-based authentication, utilizing cryptographic signatures that effectively mitigate phishing risks. Options B (Google prompt) and C (Google Authenticator app) do not offer the same level of security since they rely on software-based methods. Option D (Cloud HSM keys) is not applicable in this context, as it pertains to managing cryptographic keys in the cloud rather than user authentication.
