Question 787 of 975

Implement and manage identity and access in Microsoft Entra ID →hardMultiple SelectObjective-mapped

Quick Answer

The answer is to configure a conditional access policy targeting guest or external users and enable cross-tenant access settings to trust MFA claims from the partner tenant. This works because the conditional access policy in the resource tenant (hosting SharePoint Online) directly enforces MFA for all B2B guest users, while the cross-tenant trust setting ensures that if the guest’s home tenant has already performed MFA, that claim is accepted—avoiding redundant prompts. On the MS-102 exam, this question tests your understanding of how Entra ID conditional access policies interact with B2B collaboration, and a common trap is forgetting that simply setting a policy to require MFA for guests is insufficient without also configuring cross-tenant trust to honor MFA claims from external identity providers. A helpful memory tip is “Policy for the resource, trust for the source”—the resource tenant sets the policy, and cross-tenant trust validates the MFA from the guest’s home tenant.

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 uses Microsoft Entra ID with conditional access policies. They need to ensure that all external users who are invited via B2B collaboration must perform multi-factor authentication (MFA) when accessing the corporate SharePoint Online site. Which two configurations are required? (Choose two.)

Full question →

A
Create a conditional access policy targeting all guest users, requiring MFA, and scope to SharePoint Online.
This is the primary policy to enforce MFA for guests on the SharePoint app.
B
Enable cross-tenant access settings for the partner tenant to trust MFA claims.
Without trusting MFA from the external tenant, the resource tenant cannot enforce MFA for B2B collaboration users.
C
Configure the SharePoint Online external sharing settings to require MFA for guest users.
Why wrong: SharePoint external sharing settings control sharing capabilities but do not enforce MFA at sign-in; that is done by Conditional Access.
D
Set the guest user access level in the SharePoint admin center to require MFA.
Why wrong: There is no such setting in SharePoint admin center to require MFA; MFA enforcement is done through Microsoft Entra ID Conditional Access.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

Create a conditional access policy targeting all guest users, requiring MFA, and scope to SharePoint Online.

Option A is correct because a conditional access policy in Microsoft Entra ID can be configured to target 'Guest or external users' (the 'All guest users' scope) and require multi-factor authentication (MFA) when accessing SharePoint Online. This directly enforces MFA for B2B collaboration users accessing the corporate SharePoint site, as the policy is evaluated at the resource tenant (the tenant hosting SharePoint).

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 often confuse SharePoint's external sharing settings (which control sharing permissions) with Entra ID conditional access policies (which control authentication requirements), leading them to select Option C or D instead of recognizing that MFA enforcement must be configured at the identity layer via conditional access.

Detailed technical explanation

How to think about this question

Under the hood, B2B guest users are represented as user objects in the resource tenant's Entra ID with a UserType of 'Guest'. Conditional access policies evaluate these users based on their identity attributes, and when scoped to SharePoint Online (the 'Office 365 SharePoint Online' cloud app), the policy triggers MFA enforcement during token issuance. A subtle behavior is that if the guest user's home tenant already performs MFA, the resource tenant can trust that MFA claim via cross-tenant access settings (Option B), but this is optional and not required for the core MFA enforcement; the policy itself is the primary mechanism.

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.
