SC-900 Describe the capabilities of Microsoft Entra Practice Question
Your organization wants to enforce MFA for all users accessing the Azure portal. However, users accessing from the corporate office network should not be prompted for MFA. Which Conditional Access assignment should you configure?
⚠ Common exam trap
Watch out — candidates often confuse 'include' and 'exclude' assignments, mistakenly thinking that including trusted locations will skip MFA, when in fact you must exclude trusted locations to bypass MFA from those networks.

Correct answer & explanation
✓
Include all locations, exclude trusted locations.
Conditional Access policies evaluate assignments based on conditions such as user, app, and location. To enforce MFA for all users accessing the Azure portal while excluding the corporate office network, you must include all users and the Azure portal app, then exclude trusted locations (the corporate network). This ensures MFA is required only when access originates from outside the trusted corporate network.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Include all users, include trusted locations.
Why it's wrong here
This policy configuration would enforce Multi-Factor Authentication (MFA) for all users, irrespective of their network location. By explicitly including trusted locations, it overrides any implicit or explicit desire to exempt users on the secure corporate network from MFA, thereby requiring an additional authentication factor even when users are accessing resources from within the organization's trusted IP ranges. This creates unnecessary friction for internal users.
- ✗
Include all trusted locations.
Why it's wrong here
A Conditional Access policy configured to "Include all trusted locations" would specifically apply its defined controls, such as requiring MFA, only when users are accessing resources from within those pre-defined trusted IP ranges. Consequently, users attempting to access resources from any untrusted or external network locations would not fall under the scope of this particular policy, failing to enforce MFA for the high-risk, outside-the-perimeter access scenarios.
- ✗
Include Azure portal app, exclude trusted locations.
Why it's wrong here
This policy configuration would narrowly apply MFA requirements exclusively when users are attempting to access the Azure portal application. While it correctly excludes trusted locations from the MFA requirement, it critically fails to enforce Multi-Factor Authentication for users accessing any other applications or cloud services beyond the Azure portal. This does not meet the broader organizational objective of enforcing MFA for "all users" across various access points.
- ✓
Include all locations, exclude trusted locations.
Why this is correct
This Conditional Access policy configuration effectively enforces Multi-Factor Authentication (MFA) for all users attempting to access resources from any network location, while simultaneously creating a specific exception for trusted network environments. By including "all locations" and then explicitly excluding "trusted locations," the policy ensures MFA is mandated for external or untrusted access attempts, but users on the secure corporate network are not prompted for an additional factor, balancing robust security with user experience.

Key term
Conditional access
Conditional access is a security framework that evaluates signals like user location, device health, and risk level to grant or block access to resources in real time.
Key term
