- A
A Conditional Access policy requiring MFA for high-risk sign-ins
Why wrong: MFA requirement does not block the sign-in; it only adds a step. The requirement is to block the sign-in automatically.
- B
A user risk policy configured to require a password change
Why wrong: A user risk policy addresses compromised accounts after the fact, but does not block the current sign-in. The question specifies blocking the sign-in.
- C
A sign-in risk policy configured to block access
Sign-in risk policies in Identity Protection can block sign-ins based on risk level (e.g., High). The user can later remediate their account via a user risk policy.
- D
An MFA registration policy for all users
Why wrong: MFA registration enforcement does not block high-risk sign-ins; it only ensures users are registered for MFA.
Identity Protection Sign-In Risk Policy
This SC-900 practice question tests your understanding of describe the capabilities of microsoft entra. 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.
An organization uses Microsoft Entra ID Protection. A user's sign-in is flagged with a risk level of 'High' because of an anonymous IP address. The administrator wants to automatically block the sign-in while allowing the user to self-remediate. Which should be configured?
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
A sign-in risk policy configured to block access
A sign-in risk policy in Microsoft Entra ID Protection can be configured to automatically block access when a sign-in is detected as high risk (e.g., from an anonymous IP address). This policy operates at the sign-in level, allowing the administrator to block the sign-in while still enabling the user to self-remediate (e.g., by signing in again after the risk is mitigated). Option C directly matches this requirement.
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.
- ✗
A Conditional Access policy requiring MFA for high-risk sign-ins
Why it's wrong here
MFA requirement does not block the sign-in; it only adds a step. The requirement is to block the sign-in automatically.
When this WOULD be correct
This would be correct if the question asked for a policy that requires additional verification (MFA) for high-risk sign-ins, without blocking access, and the user can self-remediate by completing MFA.
- ✗
A user risk policy configured to require a password change
Why it's wrong here
A user risk policy addresses compromised accounts after the fact, but does not block the current sign-in. The question specifies blocking the sign-in.
When this WOULD be correct
A user risk policy requiring a password change would be correct if the question described a user risk (e.g., leaked credentials) and the goal was to force the user to self-remediate by changing their password after the risk is detected.
- ✓
A sign-in risk policy configured to block access
Why this is correct
Sign-in risk policies in Identity Protection can block sign-ins based on risk level (e.g., High). The user can later remediate their account via a user risk policy.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
An MFA registration policy for all users
Why it's wrong here
MFA registration enforcement does not block high-risk sign-ins; it only ensures users are registered for MFA.
When this WOULD be correct
This option would be correct if the question asked: 'An organization wants to ensure all users are registered for MFA before accessing cloud apps. Which policy should be configured?' In that case, an MFA registration policy would enforce registration.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The SC-900 exam frequently reuses these exact scenarios with slightly different constraints.
✓A sign-in risk policy configured to block accessCorrect answer▾
Why this is correct
Sign-in risk policies in Identity Protection can block sign-ins based on risk level (e.g., High). The user can later remediate their account via a user risk policy.
✗A Conditional Access policy requiring MFA for high-risk sign-insWrong answer — click to see why▾
Why this is wrong here
This option requires MFA for high-risk sign-ins but does not block access, which contradicts the administrator's goal to automatically block the sign-in while allowing self-remediation.
★ When this WOULD be the correct answer
This would be correct if the question asked for a policy that requires additional verification (MFA) for high-risk sign-ins, without blocking access, and the user can self-remediate by completing MFA.
Why candidates choose this
Candidates may think requiring MFA is sufficient to mitigate risk, but they overlook the explicit requirement to block the sign-in, not just challenge it.
✗A user risk policy configured to require a password changeWrong answer — click to see why▾
Why this is wrong here
The question specifies a sign-in risk (anonymous IP address), not user risk. A user risk policy targets user account compromise, not sign-in events, and would not block the sign-in based on sign-in risk.
★ When this WOULD be the correct answer
A user risk policy requiring a password change would be correct if the question described a user risk (e.g., leaked credentials) and the goal was to force the user to self-remediate by changing their password after the risk is detected.
Why candidates choose this
Candidates may confuse user risk with sign-in risk, or think that requiring a password change is a common remediation for high-risk events, not realizing that sign-in risk policies handle sign-in blocking directly.
✗An MFA registration policy for all usersWrong answer — click to see why▾
Why this is wrong here
An MFA registration policy requires users to register for MFA but does not block sign-ins or allow self-remediation for high-risk sign-ins. The question specifically asks to block access and allow self-remediation, which is achieved by a sign-in risk policy configured to block access.
★ When this WOULD be the correct answer
This option would be correct if the question asked: 'An organization wants to ensure all users are registered for MFA before accessing cloud apps. Which policy should be configured?' In that case, an MFA registration policy would enforce registration.
Why candidates choose this
Candidates may confuse MFA registration with risk-based policies, thinking that requiring MFA for all users addresses high-risk sign-ins, but it does not block access or provide self-remediation for specific risk events.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is confusing sign-in risk policies (which block or challenge at the sign-in event) with user risk policies (which require password changes after a compromise), leading candidates to choose a user risk policy when the scenario explicitly describes a sign-in-level risk from an anonymous IP.
Detailed technical explanation
How to think about this question
Under the hood, Entra ID Protection evaluates sign-in risk using real-time signals (e.g., anonymous IP, atypical travel) and assigns a risk level (Low, Medium, High). A sign-in risk policy can be configured with an action such as 'Block access' or 'Allow access with MFA'—the 'Block access' action immediately denies the authentication token, preventing the session from being established. Self-remediation occurs when the user later signs in from a trusted location or after the risk event expires, allowing the policy to evaluate the new sign-in without the previous risk flag.
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.
