The answer is to configure a conditional access policy in Microsoft Entra ID to require compliant devices. This is correct because conditional access policies act as the enforcement gatekeeper, checking device compliance—managed by Intune—before granting access to sensitive resources like SharePoint Online containing PHI. While Intune device compliance policies define the rules (encryption, OS version), they cannot block access on their own; conditional access is the mechanism that evaluates those rules and denies non-compliant devices. On the SC-900 exam, this scenario tests your understanding of how Microsoft Entra ID, Intune, and compliance policies work together to enforce zero-trust security, often appearing as a trap where candidates confuse DLP or app protection policies with device-level access control. A common memory tip is: “Intune sets the rules, but Conditional Access enforces the bouncer at the door.”
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. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
You are a compliance officer at a healthcare organization that uses Microsoft 365. The organization must comply with HIPAA regulations. You have Microsoft Purview, Microsoft Defender for Cloud Apps, and Microsoft Intune. You need to ensure that all devices accessing patient health information (PHI) are compliant with the organization's security policies, which require device encryption, a minimum OS version, and the use of a compliant mobile device management (MDM) provider. Currently, some devices are not managed by Intune. You need to enforce that only compliant devices can access PHI stored in SharePoint Online. What should you do?

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure a conditional access policy in Microsoft Entra ID to require compliant devices
Option B is correct because conditional access policies in Microsoft Entra ID can require devices to be compliant (managed by Intune) and meet compliance policies before accessing SharePoint. Option A is wrong because DLP policies do not enforce device compliance. Option C is wrong because app protection policies apply to mobile apps but do not require device management. Option D is wrong because device compliance policies require devices to be enrolled in Intune first; conditional access is needed to enforce the requirement.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Create a device compliance policy in Microsoft Intune and assign it to all users
Why it's wrong here
Compliance policy alone does not enforce access; conditional access is needed.
✗
Deploy an app protection policy in Microsoft Intune to restrict data access
Why it's wrong here
App protection policies apply to apps, not device compliance.
✓
Configure a conditional access policy in Microsoft Entra ID to require compliant devices
Why this is correct
Conditional access can require devices to be marked as compliant.
Clue confirmation
The clue word "minimum / minimize" in the question point toward this answer.
Related concept
Static NAT maps one inside address to one outside address.
✗
Create a DLP policy in Microsoft Purview to block access from non-compliant devices
Why it's wrong here
DLP does not enforce device compliance.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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.

Variation 1. An organization wants to ensure that only managed and compliant devices can access corporate email in Exchange Online. Which Microsoft Entra ID Conditional Access policy setting should they use?
easy
✓ A.Require device to be marked as compliant
B.Require approved client app
C.Require hybrid Azure AD joined device
D.Require multi-factor authentication
Why A: Correct: 'Require device to be marked as compliant' enforces compliance. Option B: 'Require MFA' is about authentication. Option C: 'Require approved client app' is for app-level. Option D: 'Require hybrid Azure AD joined' is for domain-joined devices.
