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. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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.
```powershell
Get-MgPolicyConditionalAccessPolicy -Filter "id eq '12345678-1234-1234-1234-123456789abc'" | Select-Object -ExpandProperty Conditions
```
Refer to the exhibit. You run the PowerShell command to retrieve a conditional access policy's conditions. The output shows Applications: All, Users: All, and Locations: All trusted. You need to ensure that only trusted locations are used when accessing Microsoft 365. What change should you make?

```powershell
Get-MgPolicyConditionalAccessPolicy -Filter "id eq '12345678-1234-1234-1234-123456789abc'" | Select-Object -ExpandProperty Conditions
```
A
Modify the Locations condition to include all trusted locations and exclude untrusted locations
This ensures access only from trusted locations.
B
Add a condition to block legacy authentication
Why wrong: Legacy auth is unrelated to location.
C
Under Grant, require multi-factor authentication
Why wrong: MFA is not location-specific.
D
Set sign-in frequency to 4 hours
Why wrong: Sign-in frequency controls session timeout.

Correct answer & explanation
✓
Modify the Locations condition to include all trusted locations and exclude untrusted locations
The correct answer is A because the current policy condition 'Locations: All trusted' only includes trusted locations but does not explicitly exclude untrusted locations. To ensure that only trusted locations are used when accessing Microsoft 365, you must modify the Locations condition to include all trusted locations and exclude untrusted locations. This enforces access exclusively from trusted networks, blocking any sign-in from untrusted IP ranges.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam trap: answer the scenario, not the keyword
The trap here is that candidates assume selecting 'All trusted' in the Locations condition automatically blocks untrusted locations, but in Conditional Access, conditions are evaluated as 'include' only; you must explicitly add an exclusion to deny access from untrusted locations.
Detailed technical explanation
How to think about this question
Conditional Access policies in Azure AD evaluate conditions (including Locations) against named locations, which can be defined by IPv4/IPv6 ranges, countries, or trusted networks (e.g., hybrid Azure AD joined devices or MFA-trusted IPs). The 'All trusted' option includes locations marked as trusted, but without an explicit exclusion of 'All untrusted' locations, the policy does not block access from unknown IPs. To enforce a strict location-based restriction, you must configure the Locations condition to include 'All trusted' and exclude 'All untrusted' (or specific untrusted locations), ensuring the policy applies only when the user is not coming from a trusted network.

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.
