The answer is to add the script as a device management extension (PowerShell script) in Intune, assigned to 'All Devices'. This is correct because the device management extension is the only Intune mechanism that runs PowerShell scripts in the system context during automatic enrollment, executing before the user logs on and without requiring a user session. On the MD-102 exam, this concept tests your understanding of enrollment-time versus post-enrollment script execution, with a common trap being to select a user-targeted script or a configuration profile, both of which require a logged-on user context. Remember that the device management extension is the only tool that bridges the gap between device enrollment and user logon for system-level tasks. A helpful memory tip is "System before Session" — the extension runs in the system context before any user session begins.
MD-102 Prepare infrastructure for devices Practice Question
This MD-102 practice question tests your understanding of prepare infrastructure for devices. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
Your company uses Microsoft Intune to manage Windows 10 devices. You need to deploy a PowerShell script that runs in the system context during automatic enrollment. The script must run before the user logs on. Which approach should you use?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Add the script as a device management extension (PowerShell script) in Intune, assigned to 'All Devices'.
Option A is correct because device management extension (PowerShell scripts) in Microsoft Intune run in the system context and execute during automatic enrollment before the user logs on. This is the only Intune method that supports system-context script execution at enrollment time without requiring a user session.
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.
✓
Add the script as a device management extension (PowerShell script) in Intune, assigned to 'All Devices'.
Why this is correct
Device management extension scripts run in system context during enrollment.
Related concept
Read the scenario before looking for a memorised answer.
✗
Assign the script as a compliance policy remediation.
Why it's wrong here
Compliance policies do not run scripts.
✗
Deploy the script as a proactive remediation in Microsoft Intune.
Why it's wrong here
Proactive remediations run after enrollment and in user context.
✗
Embed the script in a device configuration profile using a custom OMA-URI.
Why it's wrong here
Not possible to run PowerShell via OMA-URI.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse proactive remediations (which also run PowerShell scripts) with device management extension scripts, not realizing that proactive remediations require a user session and are intended for post-enrollment health checks, not pre-logon provisioning.
Detailed technical explanation
How to think about this question
Device management extension scripts leverage the Intune Management Extension service, which runs as LocalSystem on Windows 10/11 devices. During automatic enrollment (e.g., via Windows Autopilot or GPO), the extension downloads and executes assigned PowerShell scripts before the user logon screen appears, making it ideal for provisioning tasks like installing certificates or configuring local accounts. The script execution order is controlled by the 'Run this script using the logged on credentials' setting, which must be set to 'No' for system-context execution.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
