The correct answer is authorization, alongside authentication, because the scenario demonstrates both proving identity and enforcing permissions. Authentication is the process of verifying who the user is—here, by logging in with Microsoft Entra ID credentials—while authorization determines what that authenticated user is allowed to do, such as viewing only region-specific data on the dashboard. On the SC-900 exam, this distinction is frequently tested in real-world scenarios where a single action, like accessing an application, involves both concepts; a common trap is confusing the initial login step with the subsequent access control step. To remember, think of authentication as the “who” (identity verification) and authorization as the “what” (permission enforcement)—a simple mnemonic is “AuthN before AuthZ.”
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. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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 financial application using their Microsoft Entra ID credentials. After successful sign-in, the application displays a dashboard with data for only the regions the user is authorized to manage. Which two security concepts are demonstrated in this scenario? (Select all that apply.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Authentication
Authentication is demonstrated because the user proves their identity by logging in with Microsoft Entra ID credentials, confirming they are who they claim to be. Authorization is demonstrated because after authentication, the application restricts the dashboard to show only data for regions the user is permitted to manage, enforcing access control based on assigned permissions.
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.
✓
Authentication
Why this is correct
The sign-in with credentials verifies the user's identity, which is authentication.

✓
Authorization
Why this is correct
After authentication, the application restricts data based on the user's permissions, which is authorization.

✗
Accounting
Why it's wrong here
Accounting (auditing) would involve logging user actions, not the initial access control.
✗
Non-repudiation
Why it's wrong here
Non-repudiation ensures users cannot deny their actions (e.g., via digital signatures), not demonstrated here.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse authentication (verifying identity) with authorization (granting permissions), and may incorrectly select accounting or non-repudiation because they associate logging in with tracking or non-denial, but the scenario explicitly describes identity verification and access restriction, not logging or signature-based proof.
Detailed technical explanation
How to think about this question
Under the hood, Microsoft Entra ID uses OAuth 2.0 and OpenID Connect for authentication, issuing an ID token that verifies the user's identity. Authorization is then enforced by the application using claims from the token (e.g., roles or group memberships) to filter data access, often via attribute-based access control (ABAC) or role-based access control (RBAC). In a real-world scenario, a finance app might use Azure RBAC to assign the 'Finance Reader' role for specific regions, and the application checks these claims before rendering the dashboard.

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.
