MD-102 Practice Question: Using Microsoft Deployment Toolkit (MDT) to…
A company is using Microsoft Deployment Toolkit (MDT) to deploy Windows 11 to 200 new laptops. The deployment includes applications such as Microsoft 365 Apps for enterprise and a line-of-business (LOB) application. The LOB application requires a specific registry key to be set before installation. You have added a 'Set Registry' step in the task sequence before the application installation step. During a test deployment, the LOB application fails to install. The MDT logs show that the registry key is set correctly, but the application installer still fails. You suspect the application requires a reboot after setting the registry key. The task sequence does not have a reboot step after the registry change. Which step should you add to the task sequence?
⚠ Common exam trap
Many exam-takers think a simple wait or Group Policy refresh is sufficient, overlooking that some applications require a reboot to recognize registry changes, and that MDT's 'Restart Computer' step is the only way to enforce that reboot at the correct point in the task sequence.
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
✓
Add a 'Restart Computer' step immediately after the 'Set Registry' step
The LOB application requires a reboot after the registry key is set to make the change effective. In MDT, a 'Restart Computer' step forces a system restart, ensuring the registry modification is recognized by the application installer. Without this reboot, the installer may read stale registry data and fail, even though the key is correctly written.
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 a 'Wait' step for 60 seconds
Why it's wrong here
Waiting does not apply registry changes requiring reboot.
- ✗
Add a 'Set Task Sequence Variable' step to set a reboot variable
Why it's wrong here
Variables alone don't cause a reboot.
- ✓
Add a 'Restart Computer' step immediately after the 'Set Registry' step
Why this is correct
This ensures the registry change takes effect before application installation.
- ✗
Add a 'Run Command Line' step to run gpupdate /force
Why it's wrong here
gpupdate is for Group Policy, not registry changes.
