MD-102 Requirement rule Practice Question
You are planning to deploy a Win32 app to Windows 10 devices using Microsoft Intune. The app requires a specific registry key to be present before installation. How should you ensure the prerequisite is met?
⚠ Common exam trap
The trap is that candidates often confuse requirement rules with detection rules. Requirement rules are pre-installation checks, while detection rules are post-installation checks. In this scenario, the need is to ensure a registry key exists before installation, so a requirement rule (option C) is the correct choice, not a detection rule (option D).
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
✓
Set a requirement rule for the registry key.
Requirement rules are used to evaluate conditions that must be met before the app installation begins. By setting a requirement rule to check for the existence of the specific registry key, Intune will verify the prerequisite and only install the app if the key is present. Detection rules, on the other hand, are intended to verify the app's installation status after deployment, not to check prerequisites before installation. Therefore, option D is incorrect.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Configure the installation behavior as 'System' to bypass user context.
Why it's wrong here
Configuring installation behavior as 'System' installs the app in the system context but does not check for the prerequisite registry key. This does not ensure the key exists before installation.
- ✗
Add the registry key as a dependency.
Why it's wrong here
Adding the registry key as a dependency is not a valid method in Intune Win32 app deployment. Dependencies are other apps, not registry keys.
- ✓
Set a requirement rule for the registry key.
Why this is correct
Correct. A requirement rule evaluates device conditions before installation. By setting a rule to check for the specific registry key, Intune will only proceed if the key exists.
- ✗
Configure a detection rule to verify the registry key exists.
Why it's wrong here
Incorrect. Detection rules are used after installation to confirm the app is present, not to check prerequisites before installation. They are evaluated at each sync to determine if the app needs to be installed.
