MD-102 Prepare infrastructure for devices Practice Question
A company uses Microsoft Intune to manage its Windows devices. The IT team wants to ensure that new Windows devices can enroll without requiring users to manually enter the enrollment server address. The devices are already joined to Microsoft Entra ID. Which infrastructure component enables this automatic discovery?
⚠ Common exam trap
The trap here is attributing automatic discovery to a DNS SRV record or the Company Portal, when the cloud discovery endpoint in Microsoft Entra ID is what cloud-joined devices actually use.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The MDM discovery endpoint published in Microsoft Entra ID through the mobility settings.
Microsoft Entra ID publishes the MDM discovery endpoint when automatic enrollment is configured. A Microsoft Entra joined Windows device queries that endpoint during the join process and receives the Intune enrollment URL, so users do not need to enter a server address manually. This is the standard cloud-based discovery path.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
A DNS SRV record for _enterpriseregistration in the on-premises DNS zone.
Why it's wrong here
The _enterpriseregistration SRV record is associated with device registration for hybrid or on-premises scenarios and is not the mechanism used by Microsoft Entra joined devices to discover the Intune MDM endpoint. Relying on this record would not provide the automatic discovery required for cloud-joined Windows devices enrolling in Intune.
- ✓
The MDM discovery endpoint published in Microsoft Entra ID through the mobility settings.
Why this is correct
When automatic MDM enrollment is configured in Microsoft Entra ID, the service publishes the MDM discovery endpoint to enrolled clients. A Microsoft Entra joined device queries this endpoint during the join process and learns the Intune enrollment URL, enabling enrollment without the user typing a server address. This is the mechanism that enables automatic discovery.
- ✗
The Company Portal app installed on the device before enrollment.
Why it's wrong here
The Company Portal is used by users to enroll devices manually and to access corporate resources, but it is not the automatic discovery mechanism for Microsoft Entra joined devices. Installing it does not cause the device to locate the MDM endpoint automatically, so it does not meet the requirement described in the scenario.
- ✗
The Intune enrollment policy in the Microsoft Intune admin center.
Why it's wrong here
Intune enrollment policies in the admin center control settings such as device platform restrictions and enrollment limits, but they do not provide the discovery mechanism that lets a Microsoft Entra joined device find the MDM enrollment endpoint automatically. This policy type governs eligibility and behavior after discovery rather than the discovery itself.
