MS-102 Practice Question: Implement and manage identity and access in Microsoft Entra ID
This MS-102 practice question tests your understanding of implement and manage identity and access in microsoft entra id. 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 (Contoso) frequently collaborates with a partner company (Fabrikam) via B2B collaboration. Contoso wants to require Fabrikam's guest users to perform MFA using Contoso's MFA policies, ignoring any MFA claims from the Fabrikam home tenant. However, Fabrikam's users already have MFA enabled in their home tenant. What should Contoso configure in their cross-tenant access settings?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Disable trust for MFA from the external tenant in the cross-tenant access settings
Option D is correct because Contoso wants to ignore MFA claims from Fabrikam's home tenant and enforce its own MFA policies on Fabrikam's guest users. In cross-tenant access settings, disabling trust for MFA from the external tenant ensures that Contoso does not honor any MFA claims issued by Fabrikam, thereby requiring Fabrikam's users to perform MFA again according to Contoso's conditional access policies.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Set the inbound trust settings to accept MFA claims from Fabrikam
Why it's wrong here
This would accept the home tenant's MFA, not force Contoso's MFA.
✗
Set the inbound trust settings to accept compliant device claims
Why it's wrong here
Device compliance claims are not related to MFA enforcement.
✗
Set the inbound trust settings to block MFA and require Contoso's MFA
Why it's wrong here
There is no 'block MFA' option; the correct approach is to not accept MFA from the external tenant.
✓
Disable trust for MFA from the external tenant in the cross-tenant access settings
Why this is correct
By disabling trust for MFA claims from the external tenant, Contoso ensures that its own MFA policies apply to guest users.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may think they need to explicitly 'block MFA' (Option C) rather than understanding that disabling trust for MFA claims achieves the same effect by ignoring the external tenant's MFA, forcing Contoso's own MFA policies to apply.
Detailed technical explanation
How to think about this question
Under the hood, cross-tenant access settings in Microsoft Entra ID use inbound trust settings to control which claims (MFA, compliant device, hybrid Azure AD joined) from an external tenant are accepted. When MFA trust is disabled, the external tenant's MFA claim is ignored, and the resource tenant's conditional access policies evaluate the user as if no MFA was performed, triggering a fresh MFA challenge. This is critical in scenarios where the resource tenant has stricter MFA requirements or wants to ensure step-up authentication for sensitive apps.

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.
