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?
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.
Why this answer
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.
Exam trap
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.
How to eliminate wrong answers
Option A is wrong because the Advanced Protection Program is designed for high-risk users (e.g., executives, IT admins) and enforces hardware security keys, but it is not a policy that can be applied to all employees by default; it requires manual enrollment per user. Option C is wrong because Cloud Identity-Aware Proxy (IAP) controls access to applications based on identity and context, but it does not enforce hardware key authentication for Google Workspace apps themselves; it is used for securing access to custom or cloud-hosted apps behind a load balancer. Option D is wrong because Cloud Armor is a web application firewall and DDoS protection service that filters traffic based on IP addresses or other criteria, but it does not enforce multi-factor authentication or eliminate the need for 2FA; it cannot replace a second authentication factor.
