Quick Answer
The answer is to use a Win32 app. This is the correct choice because Win32 apps in Microsoft Intune allow you to set the 'Install behavior' to system context, granting the necessary elevated privileges, and they support custom installation scripts that can handle an untrusted certificate by installing the signing certificate first or using silent switches. On the MD-102 exam, this question tests your understanding of app deployment methods and their contextual limitations—a common trap is choosing a Line-of-Business (LOB) app, which installs in user context and requires the device to trust the app's certificate at deployment time. Remember the key distinction: LOB apps are for simple, trusted .msi or .appx files in user context, while Win32 apps are for complex, system-level deployments with certificate flexibility. A useful memory tip is "Win32 for Win-System"—if it needs system context and an untrusted cert, think Win32.
This MD-102 practice question tests your understanding of manage and maintain 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.
You manage devices with Microsoft Intune. You need to deploy a line-of-business (LOB) app that is signed with a certificate not trusted by the devices. The app requires installation in the system context. Which deployment method should you use?
Microsoft Store for Business app
Why wrong: Store apps are not LOB and require Store integration.
Win32 app
Win32 apps can be unsigned and run in system context.
Microsoft Intune LOB app (msi/appx)
Why wrong: LOB apps require a trusted certificate signature.
Web link
Why wrong: Web links only open a URL, they do not install an app.

Correct answer & explanation
Win32 app
Win32 apps in Microsoft Intune support installation in the system context via the 'Install behavior' setting, and they can be deployed using a custom installation script that handles certificate trust issues (e.g., by installing the signing certificate first or using a silent install switch). This method also allows the app to run with elevated privileges, which is required for system-context installation, and does not depend on the device trusting the app's signing certificate at deployment time.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.

Why it's wrong here
Web links only open a URL, they do not install an app.
Common exam traps
The trap here is that candidates often assume 'LOB app' must use the Intune LOB app type (MSI/APPX), but the requirement for system context and untrusted certificate forces the use of the Win32 app type, which provides the flexibility to handle certificate trust via scripting.
Detailed technical explanation
Win32 app deployment in Intune uses the Intune Management Extension to execute a detection and installation script under the SYSTEM account (via the 'Install behavior' setting). This allows the script to pre-install the necessary certificate into the Trusted Publishers or Trusted Root store using certutil or PowerShell, enabling the LOB app to install without error. In contrast, MSI LOB apps rely on the built-in Windows Installer service which validates the certificate chain at install time and will fail if the root is not trusted.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
