Question 371 of 507

Trust and security with Google Cloud →easyMultiple ChoiceObjective-mapped

Quick Answer

The answer is multi-factor authentication (MFA), also known as two-step verification (2SV). This security feature enforces the requirement to verify identity beyond a password by demanding two or more distinct factors—typically something you know (a password), something you have (a time-based one-time password from an authenticator app or a hardware security key like FIDO2), or something you are (a biometric). On the Google Cloud Digital Leader exam, this concept tests your understanding of how Identity Platform policies, such as security key enforcement and 2SV, directly mitigate credential theft. A common trap is confusing MFA with single sign-on (SSO); remember that SSO simplifies login but does not inherently add a second factor. The exam emphasizes that password compromise alone must be insufficient for access, which is exactly what MFA ensures. Memory tip: think “MFA = More Factors Always” to recall that it requires at least two distinct verification methods to enforce multi-factor authentication for Google Cloud access.

Cloud Digital Leader Trust and security with Google Cloud Practice Question

This GCDL practice question tests your understanding of trust and security with google cloud. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

A company's security policy requires all employees to verify their identity using more than just a password when accessing Google Cloud resources. What security feature enforces this requirement?

A
Password complexity requirements — enforcing long, complex passwords.
Why wrong: Strong passwords improve security but are still a single factor. Multi-factor authentication adds a second independent factor (something you have or are) that is much more resistant to compromise.
B
Multi-factor authentication (MFA) / Two-step verification (2SV).
MFA requires a second factor beyond the password — physical security keys, TOTP apps, or other verifiers. Even if a password is stolen, the second factor prevents unauthorized access.
C
IP allowlisting — only allowing access from office IP addresses.
Why wrong: IP allowlisting restricts access by network location. It doesn't verify user identity beyond the network they're on, and blocks legitimate remote access from trusted employees.
D
Session timeout — automatically logging out users after 30 minutes of inactivity.
Why wrong: Session timeout limits exposure from unattended sessions but doesn't verify identity at login. MFA is an authentication mechanism, not a session management policy.

Correct answer & explanation

✓

Multi-factor authentication (MFA) / Two-step verification (2SV).

Multi-factor authentication (MFA) / Two-step verification (2SV) is the correct answer because it explicitly requires users to provide two or more verification factors (e.g., something you know, something you have, something you are) to access Google Cloud resources. This directly enforces the policy of verifying identity beyond just a password, as MFA/2SV adds an additional layer of security by requiring a second factor such as a time-based one-time password (TOTP) from an authenticator app, a hardware security key (e.g., FIDO2), or a push notification. Google Cloud Identity Platform supports this via security key enforcement and 2SV policies, ensuring that password compromise alone is insufficient for access.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates confuse 'stronger authentication' with 'stronger passwords' (Option A) or 'access restrictions' (Option C), failing to recognize that the core requirement is adding an independent second factor, not just hardening the single password factor.

Detailed technical explanation

How to think about this question

Under the hood, Google Cloud's MFA/2SV leverages the Time-based One-Time Password (TOTP) algorithm (RFC 6238) or FIDO2/WebAuthn standards for hardware security keys, which generate cryptographically bound credentials that cannot be reused or phished. A subtle behavior is that when MFA is enforced via Google Workspace or Cloud Identity, it can be applied at the organization level or per OAuth client, and users must enroll at least one second factor before accessing resources. In a real-world scenario, an attacker who steals a user's password via phishing cannot authenticate without the second factor (e.g., a YubiKey or Google Authenticator code), even if they have the password and the user's IP address.

TExam Day Tips

Watch for words such as best, first, most likely and least administrative effort.
Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example

How this comes up in practice

A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
