- A
Authentication
Why wrong: Authentication is the process of verifying the user's identity (e.g., verifying the username and password). The scenario describes a check after authentication, so this is not the correct concept.
- B
Authorization
Authorization is the process of granting or denying access to resources based on the authenticated user's permissions. The role check determines if the user is authorized to access the user management page, making this the correct answer.
- C
Accounting
Why wrong: Accounting (or auditing) refers to tracking and logging user activities for compliance or monitoring purposes, not to the permission check itself.
- D
Non-repudiation
Why wrong: Non-repudiation ensures that a party cannot deny having performed an action, often achieved through digital signatures or audit logs. It does not relate to checking role memberships.
Quick Answer
The answer is authorization. While authentication verifies who you are—in this case, confirming the user’s identity with a username and password—authorization determines what you are allowed to do after that identity is established. The role check for the 'Admin' group is a classic authorization action because it controls access to a specific resource (the user management page) based on assigned permissions. On the Microsoft SC-900 exam, this distinction is frequently tested through scenario-based questions that describe a login step followed by a permission check; the common trap is confusing the initial login (authentication) with the subsequent access control (authorization). Microsoft’s identity and access management enforces authorization via role-based access control (RBAC), where claims in the access token, such as role membership, are evaluated. A simple memory tip: authentication answers “Are you who you say you are?” while authorization answers “Are you allowed to do that?”—think of the role check as the gatekeeper after the ID check.
SC-900 Practice Question: Describe the concepts of security, compliance, and identity
This SC-900 practice question tests your understanding of describe the concepts of security, compliance, and identity. 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 user logs into a company's application using their username and password. After logging in, the application checks whether the user belongs to the 'Admin' role before granting access to the user management page. Which security concept is primarily illustrated by the role check?

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
Authorization
The role check after login determines what actions the authenticated user is allowed to perform, specifically whether they can access the user management page. This is the essence of authorization, which controls access to resources based on identity and assigned permissions. In Microsoft identity and access management, authorization is enforced via role-based access control (RBAC), where the application verifies the user's role claim (e.g., 'Admin') in the access token.
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
Microsoft often tests the distinction between authentication and authorization by presenting a scenario where a user is already logged in and then a permission check occurs, leading candidates to mistakenly select 'authentication' because they focus on the login step rather than the subsequent access control decision.
Trap categories for this question
Scenario analysis trap
Authentication is the process of verifying the user's identity (e.g., verifying the username and password). The scenario describes a check after authentication, so this is not the correct concept.
Detailed technical explanation
How to think about this question
Under the hood, authorization in modern applications often uses OAuth 2.0 scopes and claims in JSON Web Tokens (JWTs). When the application checks the 'Admin' role, it is inspecting the 'roles' claim in the token issued by the identity provider (e.g., Microsoft Entra ID). A real-world scenario where this matters is in a multi-tenant SaaS application: a user might be authenticated but not authorized to access another tenant's data, and the role check ensures proper tenant isolation.
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.
