Quick Answer

The answer is that the policy incorrectly uses 'and' logic for user and sign-in risk, so a user with high user risk but low sign-in risk would not be blocked. This is because Conditional Access policy conditions within a single rule are combined with an implicit 'and' operator, meaning both the user risk and sign-in risk must meet the specified level for the control to apply. In this case, to block high-risk users, the policy requires both risks to be high, which fails when only one risk is elevated. On the Microsoft Cybersecurity Architect exam, this tests your understanding of how Conditional Access evaluates multiple risk conditions—a common trap is assuming you can mix risk levels in one rule without separate policies. Remember the memory tip: “One rule, one AND gate—separate policies for separate risk states.”

SC-100 Practice Question: Design security solutions for applications and data

This SC-100 practice question tests your understanding of design security solutions for applications and data. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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

{
  "properties": {
    "policyMode": "default",
    "rules": [
      {
        "name": "BlockHighRisk",
        "conditions": {
          "userRiskLevels": ["high"],
          "signInRiskLevels": ["high"]
        },
        "grantControls": {
          "builtInControls": ["block"]
        }
      },
      {
        "name": "RequireMFAForMedium",
        "conditions": {
          "userRiskLevels": ["medium"],
          "signInRiskLevels": ["medium"]
        },
        "grantControls": {
          "builtInControls": ["mfa"]
        }
      }
    ]
  }
}

Refer to the exhibit. A security administrator is reviewing a Conditional Access policy JSON. They want to ensure that users with medium risk level are prompted for multi-factor authentication (MFA), while high-risk users are blocked. The policy is not working as expected. Which issue is present in the policy?

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

✓

The policy requires both user and sign-in risk to be high to block, but a user with high user risk and low sign-in risk would not be blocked

The policy uses 'and' logic for user and sign-in risk within the same rule, meaning both must be high to block, and both must be medium to require MFA. However, the conditions are combined with implicit 'and'. For the intended effect, separate policies or different condition structure is needed. Option C is correct. Option A is wrong because the syntax is valid JSON. Option B is wrong because there is no 'Or' condition issue; it's 'and'. Option D is wrong because the policy mode is 'default'.

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.

  • ✗

    The policy mode should be 'report-only'

    Why it's wrong here

    The mode is not the issue; the logic is.

  • ✓

    The policy requires both user and sign-in risk to be high to block, but a user with high user risk and low sign-in risk would not be blocked

    Why this is correct

    Yes, the rule requires both risk levels to be high; a single high risk would not trigger the block.

    Related concept

    Read the scenario before looking for a memorised answer.

  • ✗

    The JSON syntax is invalid

    Why it's wrong here

    The JSON is valid.

  • ✗

    The conditions are combined with 'Or' instead of 'And'

    Why it's wrong here

    Conditions are combined with 'And' implicitly.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

Detailed technical explanation

How to think about this question

This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.

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.
  • Use explanations to understand the rule behind the answer.

TExam Day Tips

  • Underline the problem statement mentally.
  • 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.

Same concept, more angles

1 more ways this is tested on SC-100

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.

Variation 1. You are reviewing a Conditional Access policy in Microsoft Entra ID. The policy is intended to block sign-ins from high-risk users. However, some high-risk users are still able to sign in. What is the most likely reason?

medium
  • ✓ A.The policy is not enforced because user risk is not being evaluated (e.g., missing licenses or risk policy)
  • B.The policy does not include all client app types
  • C.The policy is set to report-only mode
  • D.The policy does not include all locations

Why A: Option C is correct because the policy only blocks based on user risk level, but if the user risk is not evaluated or the policy is not in report-only mode, it may not enforce. However, the exhibit shows the policy is enabled, but if the user risk level is not being calculated in real-time (e.g., due to licensing), it may not trigger. Option A is wrong because locations include all. Option B is wrong because client app types include all. Option D is wrong because the policy is enabled.
