SC-900 Practice Question: Describe the capabilities of Microsoft security solutions

This SC-900 practice question tests your understanding of describe the capabilities of microsoft security solutions. 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.

Exhibit

Refer to the exhibit.

```json
{
  "properties": {
    "displayName": "Block high-risk sign-ins",
    "conditions": {
      "userRiskLevels": ["high"],
      "signInRiskLevels": []
    },
    "grantControls": {
      "builtInControls": ["block"]
    }
  }
}
```

Refer to the exhibit. You are reviewing a Conditional Access policy JSON in Microsoft Entra ID. What will this policy do?

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

Block access when user risk is high

The policy JSON specifies `"userRiskLevels": ["high"]` and `"builtInControls": ["block"]`, meaning it blocks access when the user risk level is high. User risk reflects the likelihood that the user's identity is compromised, based on Microsoft's risk detection signals. Option D correctly identifies this behavior.

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.

  • Block access when user risk is medium or high

    Why it's wrong here

    Only high user risk is specified.

  • Block sign-ins when sign-in risk is high

    Why it's wrong here

    Sign-in risk levels are empty.

  • Require MFA when user risk is high

    Why it's wrong here

    Grant control is block, not MFA.

  • Block access when user risk is high

    Why this is correct

    Policy blocks based on high user risk.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is confusing user risk with sign-in risk; candidates often pick 'block sign-ins when sign-in risk is high' because they overlook the `userRiskLevels` field in the JSON and assume the policy targets sign-in risk instead.

Detailed technical explanation

How to think about this question

User risk is calculated by Microsoft Entra ID Protection using signals like leaked credentials, impossible travel, or anomalous behavior, and is stored as a property on the user object. The Conditional Access policy evaluates this risk at sign-in time by checking the `userRiskLevels` condition; if the user's current risk level matches, the policy enforces the specified controls. In real-world scenarios, blocking high-risk users prevents compromised accounts from accessing resources until the risk is remediated (e.g., via password reset or admin action).

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.
