The answer is that the enrollment restrictions are set to block personally owned devices, which is the most likely cause of the "This device is not allowed to enroll" error when users try to enroll their iOS devices via the Company Portal. In Microsoft Intune, enrollment restrictions control which device platforms and ownership types—corporate versus personal—are permitted to enroll; when personal devices are blocked, any user attempting to enroll a personally owned iOS device will see this exact error, regardless of other configurations. This scenario tests your understanding of how enrollment restrictions interact with device ownership settings, a common pitfall on the MD-102 exam where candidates often confuse enrollment blocks with later-stage policies like conditional access or terms of use. A key memory tip is to remember that enrollment restrictions are the gatekeeper: if personal devices are blocked, the error appears immediately at the enrollment screen, not after authentication or policy evaluation.
MD-102 Prepare infrastructure for devices Practice Question
This MD-102 practice question tests your understanding of prepare infrastructure for devices. 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.
You are setting up Microsoft Intune for the first time. You need to ensure that users can enroll their iOS devices using the Company Portal app. You have configured the enrollment restrictions to allow iOS enrollment. However, users report that they see an error 'This device is not allowed to enroll' when trying to enroll. What is the most likely cause?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
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 enrollment restrictions are set to block personally owned devices.
Option D is correct because enrollment restrictions must allow personal devices if users are using personal iOS devices. Option A is wrong because Apple MDM push certificate is required for enrollment, but the error message is different. Option B is wrong because terms of use appear after enrollment attempt. Option C is wrong because conditional access policies do not block enrollment but access after enrollment.
Key principle: 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.
