The answer is that the device does not meet authentication requirements, because the JSON restrictions define a version range that excludes all Windows 10 builds. Specifically, the configuration sets a minimumVersion of 10.0.22000 (Windows 11) and a maximumVersion of 10.0.22621.0 (Windows 11 22H2), so any Windows 10 device falls outside this allowed range and is blocked from enrollment. On the MD-102 exam, this scenario tests your ability to interpret JSON-based enrollment restrictions and understand that version ranges are inclusive; a common trap is assuming the error relates to user credentials or device compliance policies rather than the version filter itself. To remember this, think of the version range as a “Windows 11 only” gate—if the build number doesn’t land between the two specified values, enrollment is denied regardless of authentication status.
MD-102 Prepare infrastructure for devices Practice Question
This MD-102 practice question tests your understanding of prepare infrastructure for devices. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
Refer to the exhibit. You are configuring Windows enrollment restrictions in Intune. After applying this JSON, a user tries to enroll a Windows 10 device but receives an error that enrollment is blocked. What is the most likely cause?
Clue words in this question

Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The device does not meet authentication requirements
The JSON configuration sets 'minimumVersion' to '10.0.22000' (Windows 11) and 'maximumVersion' to '10.0.22621.0' (Windows 11 22H2), which excludes all Windows 10 builds. Since the user is attempting to enroll a Windows 10 device, it falls outside the allowed version range, causing the enrollment block. The error message 'enrollment is blocked' aligns with a version restriction failure, not an authentication issue.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
The device does not meet authentication requirements
Why this is correct
requireDeviceAuthentication prevents enrollment without proper device auth.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
The enrollment is restricted to Windows Holographic only
Why it's wrong here
Both windows10AndLater and Holographic are included.
✗
The device type filter excludes Windows 10
Why it's wrong here
It includes windows10AndLater.
✗
The user already has 5 devices enrolled
Why it's wrong here
Limit is 5, not exceeded.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates assume the error 'enrollment is blocked' always points to authentication or device count limits, but the JSON's version range silently excludes Windows 10, which is the actual root cause.
Detailed technical explanation
How to think about this question
Intune enrollment restrictions evaluate JSON policies in order, and the 'minimumVersion' and 'maximumVersion' fields use the Windows build number (e.g., 10.0.22000 for Windows 11 21H2). Windows 10 build numbers (e.g., 10.0.19041) fall below the minimum, so the device is blocked before any other checks. In real-world scenarios, administrators often mistakenly set version ranges that inadvertently exclude older but supported Windows 10 builds, causing unexpected enrollment failures.

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.
