The correct answer is to create a Conditional Access policy in Microsoft Entra ID that requires device compliance and use Intune compliance policies to block jailbroken devices, with seamless SSO. This works because Conditional Access evaluates signals from Intune—specifically, the device compliance status defined by Intune compliance policies—to grant or block access, and jailbroken devices can be flagged as non-compliant within those policies. On the SC-900 exam, this scenario tests your understanding of how Conditional Access and Intune integrate to enforce device-based controls, often contrasting with app-based controls like MAM. A common trap is choosing Azure AD Join alone, which registers a device but does not enforce compliance policies. Remember the key pairing: Conditional Access is the gatekeeper, Intune compliance policies are the rulebook, and seamless SSO provides the frictionless experience for compliant devices. A helpful mnemonic is "CIA" for Compliance, Intune, Access—where the policy checks compliance, Intune defines it, and access is the result.
SC-900 Practice Question: Describe the concepts of security, compliance, and identity
This SC-900 practice question tests your understanding of describe the concepts of security, compliance, and identity. 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.
Your organization uses Microsoft Intune and Microsoft Entra ID. You need to enforce that only compliant and managed devices can access corporate email in Microsoft 365. Additionally, if a device is jailbroken, access should be blocked. You also want to provide a seamless sign-in experience for compliant devices. You have Microsoft Entra ID P1 licenses. What should you configure?
Configure Mobile Application Management (MAM) policies to restrict access.
Why wrong: MAM applies to apps, not device compliance.
B
Configure Azure AD Join for all devices and enable device registration.
Why wrong: Device registration alone does not enforce compliance.
C
Create a Conditional Access policy in Microsoft Entra ID that requires device compliance and use Intune compliance policies to block jailbroken devices, with seamless SSO.
Conditional Access with device compliance ensures only compliant devices access email.
D
Configure Microsoft Defender for Endpoint to detect jailbroken devices.
Why wrong: Defender for Endpoint does not enforce Conditional Access.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a Conditional Access policy in Microsoft Entra ID that requires device compliance and use Intune compliance policies to block jailbroken devices, with seamless SSO.
Option D is correct because Conditional Access can require device compliance (from Intune compliance policies) and allow SSO via seamless sign-in. Option A is incorrect because MAM without device enrollment does not manage device compliance. Option B is incorrect because Windows Defender for Endpoint is for threat protection. Option C is incorrect because Azure AD Join alone does not enforce compliance policies.
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
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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.
