Quick Answer
The answer is Windows Hello for Business. This is the correct passwordless authentication method for hybrid users because it operates directly on Microsoft Entra joined Windows 10/11 devices, supporting both cloud-only and synced users without requiring additional hardware like security keys or mobile phones. For Fabrikam’s environment, Windows Hello for Business meets all requirements: it works on joined devices, eliminates the need for mobile devices for users without phones, and supports both identity types, while its built-in biometric or PIN enrollment offers the lowest administrative overhead compared to distributing FIDO2 keys or managing a PKI for certificate-based authentication. On the MS-102 exam, this scenario tests your ability to match passwordless methods to hybrid identity constraints—common traps include choosing FIDO2 for its hardware independence or Microsoft Authenticator for its ubiquity, but remember that Windows Hello for Business is the only option that combines device-bound authentication with zero enrollment infrastructure for hybrid users. Memory tip: “Hello works on joined hardware, no keys or phones required.”
This MS-102 practice question tests your understanding of implement and manage microsoft entra identity and access. 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.
Your organization, Fabrikam Inc., uses Microsoft Entra ID with a hybrid identity configuration. You have 500 cloud-only users and 5,000 synced users from on-premises Active Directory. The company wants to implement a passwordless authentication strategy. The following requirements must be met: 1) All users must be able to sign in without a password on Windows 10/11 devices that are Microsoft Entra joined. 2) Users who are not assigned a mobile phone must be able to use a security key (FIDO2). 3) The solution must work for both cloud-only and synced users. 4) The passwordless method should require the lowest administrative overhead for enrollment. Which passwordless authentication method should you recommend?
Certificate-based authentication
Why wrong: Requires certificate infrastructure and manual enrollment.
Microsoft Authenticator app
Why wrong: Requires a mobile phone, which not all users have.
FIDO2 security keys
Why wrong: Security keys require physical distribution and user enrollment.
Windows Hello for Business
Works on joined devices, supports all users, and can be deployed via policy.

Correct answer & explanation
Windows Hello for Business
Option C is correct because Windows Hello for Business works on Microsoft Entra joined devices and supports both cloud-only and synced users, and can be deployed with minimal enrollment effort. Option A is wrong because FIDO2 security keys require key distribution and enrollment. Option B is wrong because Microsoft Authenticator requires a mobile device. Option D is wrong because certificate-based authentication requires PKI infrastructure.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.

Variation 1. Your organization uses Microsoft Entra ID for identity management. You need to ensure that users can access internal applications using single sign-on (SSO) without storing passwords in the cloud. Which authentication method should you implement?
easyWhy B: Windows Hello for Business is correct because it enables passwordless single sign-on (SSO) to internal applications using biometric or PIN credentials, with the private key stored on the user's device rather than in the cloud. This meets the requirement of no passwords stored in the cloud while still providing seamless SSO access.
