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. 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.
A security architect is implementing a Zero Trust strategy. They state that all access requests must be verified continuously, regardless of where the request originates (corporate network or remote). They also emphasize that access is granted based on a policy that evaluates user identity, device health, location, and risk in real-time. Which Zero Trust guiding principle does this scenario primarily illustrate?
Correct. The 'Verify explicitly' principle means always authenticating and authorizing based on all available signals—identity, device, location, risk—not just network location.
B
Use least privilege access
Why wrong: 'Use least privilege access' focuses on minimizing permissions and granting just-in-time/just-enough access, not on continuous verification.
C
Assume breach
Why wrong: 'Assume breach' is about segmenting access, monitoring threats, and minimizing blast radius as if a breach has already occurred, not about the verification process itself.
D
Enforce session controls
Why wrong: 'Enforce session controls' is a technique used within Zero Trust but is not one of the three core principles defined by Microsoft.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Verify explicitly
The scenario explicitly describes continuous verification of all access requests based on real-time signals (user identity, device health, location, risk). This directly maps to the 'Verify explicitly' Zero Trust principle, which mandates that every access attempt must be authenticated and authorized using all available data points before granting access, regardless of network location.
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 often confuse 'Verify explicitly' with 'Assume breach' because both involve continuous monitoring, but 'Verify explicitly' is specifically about authenticating and authorizing every request, while 'Assume breach' is about containment and detection after a compromise.
Detailed technical explanation
How to think about this question
Under the hood, 'Verify explicitly' relies on technologies like Conditional Access in Azure AD, which evaluates signals such as user risk (from Identity Protection), device compliance (via Intune), and real-time location (IP geolocation) before issuing a token. For example, a request from a non-compliant device or a high-risk user would be blocked or require MFA even if the user is on the corporate network, enforcing the principle that trust is never implicit.

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.

What is the correct answer to this question?
The correct answer is: Verify explicitly — The scenario explicitly describes continuous verification of all access requests based on real-time signals (user identity, device health, location, risk). This directly maps to the 'Verify explicitly' Zero Trust principle, which mandates that every access attempt must be authenticated and authorized using all available data points before granting access, regardless of network location.
