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. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 scans their fingerprint to unlock a corporate laptop. After unlocking, the user attempts to open a confidential database. The system checks the user's role and grants access because the user is a member of the 'Data Analyst' group. Which two security concepts are demonstrated in this scenario?
Correct. The fingerprint scan authenticates the user, and the role check authorizes access to the database.
B
Confidentiality and integrity
Incorrect. Confidentiality and integrity are security goals, not the specific concepts demonstrated by the login and access control steps.
C
Identification and non-repudiation
Why wrong: Incorrect. Identification is claiming an identity, but the scenario shows authentication (proof). Non-repudiation is not demonstrated here.
D
Availability and accountability
Why wrong: Incorrect. Availability ensures resources are accessible, and accountability tracks actions, but neither is directly shown in the login and access decision.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Authentication and authorization
The fingerprint scan is a form of authentication, verifying the user's identity through a biometric factor. The subsequent check of the user's group membership ('Data Analyst') to grant access to the database is authorization, determining what resources the authenticated user can access. This scenario directly maps to the identity and access management (IAM) concepts of authentication (proving who you are) and authorization (what you are allowed to do).
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 confuse 'identification' (claiming an identity, e.g., typing a username) with 'authentication' (proving that identity, e.g., fingerprint), and they may incorrectly select Option C because they see the fingerprint as identification rather than a proof factor.
Trap categories for this question
Command / output trap

Scenario analysis trap
Incorrect. Identification is claiming an identity, but the scenario shows authentication (proof). Non-repudiation is not demonstrated here.
Detailed technical explanation
How to think about this question
Under the hood, authentication in Windows environments often uses Kerberos (RFC 4120) or NTLM, where the fingerprint scan triggers a credential provider to validate against Active Directory or a local SAM database. Authorization then relies on access control lists (ACLs) and security tokens containing group SIDs (e.g., S-1-5-21-... for 'Data Analyst'), which the system checks against the resource's discretionary access control list (DACL) to determine if access is granted. A subtle behavior is that if the user's token is not refreshed after group membership changes, authorization may fail until re-authentication.

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.
