The correct choice is to use the 'Switch to Intune' option in the device's 'Access work or school' settings. This feature is specifically designed for a seamless migration from a legacy on-premises MDM to Intune without reset, as it triggers an automatic MDM enrollment switch by communicating directly with the Intune service, preserving all existing data and settings on Windows 10 devices already joined to Microsoft Entra ID. On the MD-102 exam, this question tests your understanding of cloud-native migration paths versus disruptive methods like Autopilot resets or PPKG re-enrollment; a common trap is choosing Group Policy, which only configures future enrollment and cannot switch an existing MDM authority. Remember the key distinction: the 'Switch to Intune' option is the only non-destructive, user-driven method for moving devices already under legacy management—think of it as a "soft handoff" that keeps the device state intact while changing the management backend.
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 the Intune administrator for a small business with 50 Windows 10 devices that are currently managed by a legacy on-premises MDM. The company wants to move to Microsoft Intune for cloud management. All devices are already joined to Microsoft Entra ID. You need to migrate the devices to Intune management without resetting them. You have the following options: A) Use Windows Autopilot to reset the devices and re-enroll. B) Use the 'Switch to Intune' option in the device's 'Access work or school' settings. C) Use a provisioning package (PPKG) to enroll devices. D) Use Group Policy to configure MDM enrollment. Which option should you choose?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use the 'Switch to Intune' option in the device's 'Access work or school' settings
The 'Switch to Intune' option in the device's 'Access work or school' settings is the correct choice because it allows a seamless migration from a legacy on-premises MDM to Microsoft Intune without requiring a device reset. This feature, available on Windows 10 devices already joined to Microsoft Entra ID, triggers an automatic MDM enrollment switch by communicating with the Intune service, preserving all existing data and settings.
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.
✗
Use Windows Autopilot to reset the devices and re-enroll
Why it's wrong here
Disruptive; not needed for existing Entra ID join.
✗
Use Group Policy to configure MDM enrollment
Why it's wrong here
Group Policy cannot switch MDM authority.
✓
Use the 'Switch to Intune' option in the device's 'Access work or school' settings
Why this is correct
Non-disruptive migration for Entra ID joined devices.

✗
Use a provisioning package (PPKG) to enroll devices
Why it's wrong here
PPKG is for fresh enrollment, not migration.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse the 'Switch to Intune' option with a simple enrollment method, assuming any enrollment method (like PPKG or Group Policy) can perform a non-destructive migration, when in fact only the built-in switch option is designed to handle the transition from an existing MDM without a reset.
Detailed technical explanation
How to think about this question
The 'Switch to Intune' option leverages the MDM enrollment authority change protocol, where the device sends a discovery request to the Intune service, which then updates the enrollment authority in the device's MDM configuration. Under the hood, this triggers a re-enrollment using the existing Entra ID token, ensuring the device remains compliant without re-joining or resetting. In real-world scenarios, this is critical for organizations that have already invested in Entra ID join and need to avoid the downtime and data loss associated with a full wipe.

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.
