MS-900 Describe cloud concepts Practice Question

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

{
  "policy": {
    "description": "Conditional Access Policy: Block legacy authentication for all users except emergency accounts.",
    "conditions": {
      "clientAppTypes": ["exchangeActiveSync", "otherClients"],
      "users": {
        "includeUsers": ["All users"],
        "excludeUsers": ["EmergencyAccount@contoso.com"]
      }
    },
    "grantControls": {
      "builtInControls": ["block"]
    }
  }
}

Refer to the exhibit. A Contoso administrator configures a Conditional Access policy as shown. Users report they cannot access email on their Android phones using the default email app. What is the most likely cause?

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.
