MS-900 Practice Question: Describe security, compliance, privacy, and trust in Microsoft 365
This MS-900 practice question tests your understanding of describe security, compliance, privacy, and trust in microsoft 365. 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.
```
$policies = Get-MgIdentityConditionalAccessPolicy
foreach ($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.
Refer to the exhibit.
```
$policies = Get-MgIdentityConditionalAccessPolicy
foreach ($policy in $policies) {
if ($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.
Option D is correct because the script checks if the policy state is enabled, but does not check if the policy is in 'report-only' mode. A policy can be enabled but set to report-only, which does not enforce MFA. Option A is wrong because the script checks all enabled policies. Option B is wrong because the script is used for policy listing, not enforcement. Option C is wrong because the script does not modify policies.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.

Common exam traps
Common exam trap: authentication is not authorization
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Detailed technical explanation
How to think about this question
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
KKey Concepts to Remember
Authentication checks who the user is.
Authorization controls what the user is allowed to do after login.
Privilege levels affect access to EXEC and configuration commands.
AAA, TACACS+ and RADIUS can separate login success from command access.
TExam Day Tips
→Do not assume successful login means full administrative access.
→Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
→Separate login problems from permission problems before choosing the answer.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
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.
