The correct answer is to configure a detection rule to verify the registry key exists. In Microsoft Intune, Win32 app prerequisite detection rules are specifically designed to check for conditions like file presence, registry key values, or custom scripts before the app installation begins; if the rule evaluates to false, Intune skips the installation entirely. This directly addresses the requirement because a detection rule acts as a gatekeeper, ensuring the target system has the necessary registry key before the app is deployed. On the MD-102 exam, this concept tests your ability to distinguish detection rules from requirements rules (which check OS architecture or version), dependencies (which check for other apps), and installation behavior (which controls user context). A common trap is confusing detection rules with requirements rules—remember that detection rules verify the prerequisite state on the device, while requirements rules filter eligible devices upfront. Memory tip: “Detect before you deploy” — detection rules confirm the environment is ready, not just the device is eligible.
MD-102 Manage applications Practice Question
This MD-102 practice question tests your understanding of manage applications. 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.
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?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure a detection rule to verify the registry key exists.
Option A is correct because you can use detection rules to check for the registry key; if not found, Intune will not attempt installation. Option B is wrong because requirements rules are for architecture/OS. Option C is wrong because dependencies are for other apps. Option D is wrong because installation behavior is for user context.
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.
✗
Configure the installation behavior as 'System' to bypass user context.
Why it's wrong here
Does not address prerequisite.
✗
Add the registry key as a dependency.
Why it's wrong here
Dependencies are for other apps, not registry keys.
✗
Set a requirement rule for the registry key.
Why it's wrong here
Requirement rules are for OS version, processor architecture, etc.
✓
Configure a detection rule to verify the registry key exists.
Why this is correct
Detection rules can be used to check prerequisites.

TExam Day Tips
→Underline the problem statement mentally.
→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.
