The answer is to check that the MDM enrollment URL (https://enrollment.manage.microsoft.com) is reachable and not blocked by a proxy. This is correct because after a Windows update, network or proxy settings can be reset or altered, preventing devices from reaching the required Intune enrollment endpoint even when internet connectivity appears normal. On the MD-102 exam, this scenario tests your understanding that MDM enrollment relies on specific service URLs, not general internet access, and that domain-joined devices often use Group Policy to configure proxy exceptions. A common trap is to blame firewall rules or user credentials, but the core issue is routing to the enrollment service. Remember the mnemonic “URL First” — always verify the enrollment URL is accessible before diving into deeper configuration checks.
MD-102 Manage and maintain devices Practice Question
This MD-102 practice question tests your understanding of manage and maintain 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.
You manage Windows 10 devices with Microsoft Intune. Users report that after a recent Windows update, some devices fail to enroll in mobile device management (MDM). You verify that the devices are domain-joined and can reach the internet. Which configuration should you check first?

Correct answer & explanation
✓
Check that the MDM enrollment URL (https://enrollment.manage.microsoft.com) is reachable and not blocked by a proxy.
Option D is correct because the MDM enrollment URL must be accessible and properly configured in Group Policy or Intune. Option A is wrong because BitLocker is not related to enrollment. Option B is wrong because Windows Defender Firewall is not the primary cause. Option C is wrong because user credentials are valid but routing is the 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.
✗
Confirm that the user is assigned a Microsoft Entra ID P1 license.
Why it's wrong here
License assignment alone does not prevent enrollment if the URL is unreachable.
✗
Verify that the BitLocker recovery key is backed up to Microsoft Entra ID.
Why it's wrong here
BitLocker recovery is unrelated to MDM enrollment.
✗
Ensure the Windows Defender Firewall allows inbound RPC traffic.
Why it's wrong here
Firewall rules for RPC are not required for MDM enrollment.
✓
Check that the MDM enrollment URL (https://enrollment.manage.microsoft.com) is reachable and not blocked by a proxy.
Why this is correct
The enrollment URL must be reachable for successful MDM enrollment.

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.
