Why Your Conditional Access Policy Is Not Prompting for MFA: Report-Only Mode
This MS-900 practice question tests your understanding of describe security, compliance, privacy, and trust in microsoft 365. 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.
Exhibit
Refer to the exhibit.
```
$policies = Get-MgIdentityConditionalAccessPolicy
foreach ($policy in $policies) {
if ($policy.State -eq 'enabled') {
Write-Host "$($policy.DisplayName) is enabled"
}
}
```
Refer to the exhibit. A Microsoft 365 administrator runs the PowerShell script against Microsoft Entra ID. The script outputs several enabled Conditional Access policies. However, users report they are not prompted for MFA even though there is an enabled policy that should require MFA for all users. What is the most likely reason?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Exhibit
Refer to the exhibit.
```

if ($policy.State -eq 'enabled') {
Write-Host "$($policy.DisplayName) is enabled"
}
}
```
A
The policy is set to 'report-only' mode.
A policy in report-only mode does not enforce MFA.
B
The script is not executed with administrative privileges.
Why wrong: Administrative privileges are needed to run the script, but that doesn't affect MFA enforcement.
C
The script does not run against all policies.
Why wrong: The script retrieves all policies.
D
The script disables the MFA policy inadvertently.
Why wrong: The script only reads policies, it does not modify them.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The policy is set to 'report-only' mode.
The most likely reason users are not prompted for MFA despite an enabled Conditional Access policy requiring MFA is that the policy is set to 'report-only' mode. In report-only mode, the policy is evaluated and logged but not enforced, meaning users will not be prompted for MFA. This is a common configuration used for testing before enabling the policy in 'on' mode.
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 may assume any 'enabled' policy is enforced, but Microsoft distinguishes between 'enabled' (the policy is active) and 'enforced' (the policy applies controls), and report-only mode is a separate state that still shows as enabled in PowerShell output.
Detailed technical explanation
How to think about this question
Conditional Access policies in Microsoft Entra ID have three states: 'on' (enforced), 'off' (disabled), and 'report-only' (evaluated but not enforced). The report-only mode uses the same evaluation engine as enforcement but logs results to the Sign-in logs without blocking or prompting users. This allows administrators to validate policy impact before full deployment, but if left in report-only, MFA prompts will not occur.

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.
