The answer is that the policy requires MFA for all external users accessing any cloud app. This is correct because the Conditional Access policy in Microsoft Entra ID is configured with two key assignments: it targets "all external users" as the identity scope, and applies to "all cloud apps" as the resource scope, with the grant control set to require multi-factor authentication. There are no exclusions for specific apps, user roles, or user types like guests, so every external identity—whether a B2B collaboration guest, a partner, or a vendor—must pass MFA before accessing any cloud application. On the SC-900 exam, this scenario tests your ability to read a policy’s assignments and understand that "external users" is a broader category than just "guest users," a common trap. Remember the memory tip: "All external, all apps, no exclusions" equals MFA for everyone outside your tenant.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Requires MFA for all external users accessing any cloud app
Option D is correct because the policy includes all external users and all cloud apps, requiring MFA. Option A is incorrect because it does not exclude any apps. Option B is incorrect because it includes all external users, not just guest users. Option C is incorrect because it does not exclude external users with specific roles.
Key principle: 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.

Variation 1. Refer to the exhibit. You are reviewing a conditional access policy in Microsoft Entra ID. The policy is enabled and applies to all cloud apps. Which users are affected by this policy?
easy
A.All users who are members of any Azure AD administrative role
B.All users who are members of the Global Administrator role only
✓ C.All users who are members of the Global Administrator or Exchange Administrator role
D.All users in the organization
Why C: Option D is correct because the property 'includeRoles' specifies that only users assigned the Global Administrator or Exchange Administrator roles are included. Option A is wrong because the policy does not apply to all users. Option B is wrong because it applies only to roles, not all users. Option C is wrong because it does not apply to all admin roles, only the two specified.
