The answer is to configure automatic enrollment via Microsoft Entra ID for Windows devices, deploy conditional access policies that require compliance for iOS and Android, and run a communications campaign to drive enrollment. This approach is correct because automatic enrollment via Microsoft Entra ID scales Windows device registration without user intervention, while conditional access policies enforce encryption and a 6-digit PIN on non-compliant Android and iOS devices, directly addressing the security team’s mandates and the 95% enrollment target. On the MD-102 exam, this scenario tests your ability to combine automated enrollment, compliance enforcement, and user awareness to meet a business goal, often appearing as a multi-step design question where a common trap is to rely solely on manual enrollment or to forget that conditional access requires prior enrollment. A useful memory tip is “Auto for Windows, Condition for Mobile, Campaign for Culture” — remember that automation handles Windows at scale, conditional access forces mobile compliance, and a communications campaign bridges the gap to hit aggressive adoption targets.
MD-102 Prepare infrastructure for devices Practice Question
This MD-102 practice question tests your understanding of prepare infrastructure for devices. 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.
You are the endpoint administrator for Contoso, Ltd., a company with 10,000 employees. The environment includes Windows 10/11 devices, iOS/iPadOS, and Android Enterprise devices. The company recently acquired a subsidiary that uses non-compliant Android devices. The security team mandates that all devices must have encryption enabled and a PIN of at least 6 digits. Additionally, the company wants to use Microsoft Defender for Endpoint on all Windows devices. Currently, only 60% of devices are enrolled in Intune. The CIO wants to increase enrollment to 95% within 6 months. You need to design a device preparation strategy. Which approach should you recommend?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "least"
Why it matters: You want the option with minimum overhead, fewest steps, or lowest impact — not the most feature-rich or comprehensive answer.
Deploy Windows Autopilot for all new devices and ignore existing devices.
Why wrong: This does not address existing devices.
B
Purchase a third-party MDM tool to manage non-compliant devices.
Why wrong: This adds cost and complexity without solving the enrollment gap.
C
Ask all users to manually enroll their devices using the Company Portal app.
Why wrong: Manual enrollment is not scalable for 10,000 devices.
D
Configure automatic enrollment via Microsoft Entra ID for Windows devices, deploy conditional access policies that require compliance for iOS/Android, and run a communications campaign to drive enrollment.
This leverages automation and policy enforcement to increase enrollment.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure automatic enrollment via Microsoft Entra ID for Windows devices, deploy conditional access policies that require compliance for iOS/Android, and run a communications campaign to drive enrollment.
Option D is correct because it leverages Microsoft Entra ID automatic enrollment for Windows devices (via Group Policy or MDM discovery), which scales enrollment without user intervention, and uses Conditional Access policies to enforce compliance for iOS/Android devices, requiring encryption and a 6-digit PIN. This approach addresses the 95% enrollment target within 6 months by combining automated enrollment, compliance enforcement, and user awareness, while also integrating Microsoft Defender for Endpoint for Windows devices.
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
The trap here is that candidates may assume manual enrollment (Option C) is sufficient, overlooking the scalability and enforcement capabilities of automatic enrollment and Conditional Access, which are essential for achieving high enrollment rates in a large enterprise with mixed device platforms.
Detailed technical explanation
How to think about this question
Automatic enrollment for Windows devices uses MDM discovery via DNS CNAME records or Group Policy, triggering enrollment during Microsoft Entra ID join or hybrid join. Conditional Access policies evaluate device compliance status (e.g., encryption, PIN length) before granting access to cloud apps, and can block non-compliant devices, creating a strong incentive for enrollment. In real-world scenarios, a communications campaign combined with a grace period in Conditional Access helps users transition without productivity loss, while Microsoft Defender for Endpoint onboarding can be automated via Intune device configuration profiles.

Key takeaway

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.
