AZ-500 Secure identity and access Practice Question
This AZ-500 practice question tests your understanding of secure 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.
You need to ensure that external users who are invited to collaborate via Microsoft Entra B2B can only access the applications assigned to them. Which configuration should you use?
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 that applies to guest users and targets the specific applications.
Option B is correct because Conditional Access policies in Microsoft Entra ID can be scoped to guest/external users and specific applications, allowing you to enforce access controls such as requiring MFA or blocking access for unapproved apps. This directly meets the requirement to restrict B2B guest users to only the applications assigned to them, without affecting other sign-in behaviors or tenant-wide settings.
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.
✗
Require guest users to register for MFA before accessing any applications.
Create a Conditional Access policy that applies to guest users and targets the specific applications.
Why this is correct
Conditional Access can restrict guest access to specific apps.

✗
Configure cross-tenant access settings to block all applications except those assigned.
Why it's wrong here
Cross-tenant access settings control trust and access at the tenant level, not per application.
✗
Configure SharePoint external sharing settings to limit application access.
Why it's wrong here
SharePoint settings only affect SharePoint.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse cross-tenant access settings (which manage trust and sharing at the tenant level) with per-application access control, leading them to choose Option C even though it cannot enforce app-specific restrictions for individual guest users.
Detailed technical explanation
How to think about this question
Conditional Access policies evaluate signals like user type (guest), application ID, and device state to grant or block access. Under the hood, the policy is enforced during token issuance by Azure AD STS; if the policy blocks access, the token is not issued, effectively preventing the guest user from reaching the application. This is distinct from application assignment in the enterprise application blade, which controls who can see and launch the app in the My Apps portal but does not enforce runtime access unless combined with Conditional Access or SAML app role assignments.

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.
