- A
Define the roles as Microsoft Entra ID app roles and include them in the token claims.
Why wrong: Microsoft Entra ID app roles are static and require updating the app manifest; they are not suitable for dynamic role mappings stored in a database.
- B
Store the role mappings in an Azure SQL Database and use a custom authorization policy that queries the database after authentication.
This allows dynamic role assignments and leverages policy-based authorization in ASP.NET Core.
- C
Include the roles as claims in the Microsoft Entra ID token by using a custom claim mapping policy.
Why wrong: Custom claim mapping can add roles from Microsoft Entra ID but not from an external database; it would require synchronization.
- D
Store the role mappings in the web.config file and read them at runtime.
Why wrong: web.config is static, not secure for sensitive data, and cannot be updated dynamically without redeployment.
AZ-204 Implement Azure security Practice Question
This AZ-204 practice question tests your understanding of implement azure security. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 are developing an ASP.NET Core web API that authenticates users via Microsoft Entra ID. The application needs to authorize access to resources based on custom roles (e.g., 'Admin', 'Editor') that are not present in Microsoft Entra ID. The role mappings are dynamic and stored in an application database. How should you implement authorization?
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
Store the role mappings in an Azure SQL Database and use a custom authorization policy that queries the database after authentication.
Option B is correct because the custom roles are dynamic and stored in an application database, not in Microsoft Entra ID. After authentication, a custom authorization policy can query the database to retrieve the role mappings for the authenticated user and enforce access control. This approach decouples role management from the identity provider and supports dynamic role assignments.
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 assume custom roles must be embedded in the token via claims, overlooking that dynamic roles from a database can be evaluated post-authentication using a custom authorization policy.
Detailed technical explanation
How to think about this question
Under the hood, a custom authorization policy in ASP.NET Core implements IAuthorizationPolicyProvider or uses the built-in AuthorizationHandler to evaluate claims against database-stored roles. The policy typically calls a repository or DbContext after the user is authenticated, mapping the user's object ID (sub claim) to roles in the database. This pattern is common in multi-tenant applications where role assignments change frequently and cannot be embedded in tokens due to size limits (e.g., 200 claims in a Microsoft Entra ID token).
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
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.
