Google Workspace Advanced Protection Program, which enforces hardware security key requirements for high-risk users
Why wrong: The Advanced Protection Program provides the strongest protections for specific high-risk individuals (executives, admins). For an organization-wide requirement for all employees, a broader 2SV policy requiring hardware security keys is the correct administrative control.
- B
Google Workspace 2-Step Verification policy configured to require hardware security keys (FIDO2/WebAuthn) for all employees, making it impossible to sign in without a physical key
Google Workspace administrators can configure the 2SV enrollment and method requirements in the Admin Console. Setting the policy to require security keys (and disabling other 2SV methods) enforces hardware key use organization-wide. Hardware keys are phishing-resistant because they cryptographically verify the site they're authenticating to.
- C
Google Cloud Identity-Aware Proxy, which enforces hardware key authentication for all Google Workspace apps
Why wrong: IAP provides application-level access control for web applications hosted on Google Cloud. It's not the tool for enforcing hardware key requirements for Google Workspace sign-in.
- D
Cloud Armor, which blocks sign-in attempts that don't come from corporate IP addresses, eliminating the need for 2FA
Why wrong: IP allowlisting through Cloud Armor doesn't apply to Google Workspace sign-in and wouldn't eliminate phishing risk (attackers can operate from allowed IPs). Hardware keys provide cryptographic authentication that makes phishing irrelevant.
Quick Answer
The answer is the Google Workspace 2-Step Verification policy configured to require hardware security keys (FIDO2/WebAuthn) for all employees. This is correct because the policy allows administrators to enforce a physical security key as the sole second factor, effectively blocking phishing-vulnerable methods like SMS or authenticator app codes by making it impossible to complete sign-in without the key. On the Google Cloud Digital Leader exam, this tests your understanding of how Workspace security policies map to real-world phishing defense, often appearing as a scenario where you must choose the policy that eliminates weak factors rather than just adding them. A common trap is selecting a general security setting that permits multiple factors; remember that the key phrase is “enforce hardware security key” to lock out all other options. Memory tip: think “FIDO2 forces out the fakes” — if the policy doesn’t require the key, it doesn’t block the phishing.
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. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 employees use Google Workspace for email, documents, and collaboration. The IT team wants to require all employees to use a physical security key (like a YubiKey) as their second authentication factor when signing in — eliminating phishing-vulnerable SMS and authenticator app codes. Which Google Workspace security capability supports this requirement?
Answer choices

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Google Workspace 2-Step Verification policy configured to require hardware security keys (FIDO2/WebAuthn) for all employees, making it impossible to sign in without a physical key
Option B is correct because Google Workspace's 2-Step Verification policy allows administrators to enforce the use of hardware security keys (FIDO2/WebAuthn) as the sole second factor. This policy can be configured to require a physical security key for all employees, effectively blocking sign-ins that use SMS or authenticator app codes, which are vulnerable to phishing. The policy directly meets the IT team's requirement to eliminate phishing-vulnerable authentication methods.
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
Google Cloud often tests the distinction between a user-level program (Advanced Protection Program) and an organization-wide policy (2-Step Verification policy), leading candidates to choose Option A because it mentions hardware security keys, but they miss that it is not a blanket enforcement for all employees.
Detailed technical explanation
How to think about this question
Under the hood, the 2-Step Verification policy enforces FIDO2/WebAuthn standards, which use public-key cryptography to bind the security key to the user's account, preventing phishing even if credentials are stolen. A subtle behavior is that if a user loses their security key, they must be enrolled in a backup method (e.g., backup codes) or be temporarily exempted by an admin, as the policy can be set to 'required' with no fallback to SMS or TOTP. In a real-world scenario, this policy is critical for organizations subject to compliance frameworks like SOC 2 or FedRAMP, where phishing-resistant MFA is mandatory.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
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.
