The answer is Option B: use ConfigMgr co-management with Intune, then gradually transition workloads to Intune, and finally switch devices to Entra ID join. This is correct because co-management allows you to keep the existing ConfigMgr infrastructure and domain join intact while you selectively move workloads like compliance policies or Windows Update to Intune, minimizing user disruption and leveraging the high-speed WAN link. On the MD-102 exam, this scenario tests your understanding of co-management as the least disruptive migration path for existing domain-joined ConfigMgr devices, especially when you have a large fleet and a tight timeline. A common trap is choosing Autopilot or wipe-and-load options, which require device resets and re-provisioning, causing significant downtime. Remember the memory tip: "Co-manage first, then cut the cord" — keep both management authorities active until Intune handles all workloads, then switch to Entra ID join.
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 endpoint administrator for Contoso Ltd., a multinational company with 10,000 Windows 10 and 11 devices managed by Microsoft Intune. The company recently acquired a subsidiary that uses on-premises Active Directory and Configuration Manager. The subsidiary's devices are not joined to Microsoft Entra ID. Your goal is to migrate these devices to cloud management with Intune within six months. The subsidiary has 2,000 devices, all running Windows 10. The devices are currently domain-joined and managed by ConfigMgr. You need to choose the most efficient migration strategy that minimizes user disruption and leverages existing investments. The subsidiary has a high-speed WAN link to the corporate network. You have the following options: A) Use ConfigMgr to deploy a task sequence that performs a wipe-and-load with Windows Autopilot, then enroll in Intune. B) Use ConfigMgr co-management with Intune, then gradually transition workloads to Intune, and finally switch devices to Entra ID join. C) Use a provisioning package (PPKG) to join devices to Entra ID and enroll in Intune, while keeping ConfigMgr client for legacy apps. D) Use Windows Autopilot for existing devices by uploading hardware hashes, resetting devices, and re-provisioning. 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 ConfigMgr co-management with Intune, then gradually transition workloads to Intune, and finally switch devices to Entra ID join
Option B is correct because co-management allows you to gradually transition Configuration Manager workloads to Intune without disrupting existing management, leveraging the existing ConfigMgr infrastructure and high-speed WAN link. This minimizes user disruption by keeping devices domain-joined initially, then switching to Entra ID join after workloads are migrated, which is the most efficient path for 2,000 existing domain-joined devices.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✗
Use a provisioning package (PPKG) to join devices to Entra ID and enroll in Intune, while keeping ConfigMgr client for legacy apps
Why it's wrong here
Leads to dual management without co-management benefits.

Why it's wrong here
Disruptive and not leveraging ConfigMgr.

Why it's wrong here
Disruptive and does not leverage co-management.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often choose Autopilot or PPKG options because they seem 'modern,' but for existing domain-joined devices with ConfigMgr, co-management is the least disruptive and most efficient migration path, not a full wipe or provisioning package.
Detailed technical explanation
How to think about this question
Co-management uses a ConfigMgr client and Intune MDM agent side-by-side, with a workload slider to gradually move policies (e.g., compliance, resource access, Windows Update) from ConfigMgr to Intune. The high-speed WAN link ensures that ConfigMgr distribution points remain accessible during the transition, and devices can later switch from hybrid Entra ID join to full Entra ID join using a Group Policy or Intune policy, avoiding a full device reset.

Real-world example
How this comes up in practice
A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
