- A
Microsoft Entra ID Conditional Access
Why wrong: Conditional Access can require device compliance, but it only works for applications that support modern authentication. The legacy app does not, so this alone is insufficient.
- B
Microsoft Entra ID Application Proxy
Application Proxy publishes the legacy app to the cloud, adds Microsoft Entra ID authentication, and allows Conditional Access policies to enforce device compliance.
- C
Microsoft Entra ID Identity Protection
Why wrong: Identity Protection detects risks but does not provide a way to add modern authentication to a legacy application.
- D
Microsoft Entra ID Privileged Identity Management
Why wrong: PIM manages privileged roles and does not address application access or device compliance requirements.
Quick Answer
The answer is Microsoft Entra ID Application Proxy. This is the correct choice because it allows you to enforce device compliance on legacy apps via application proxy, bridging the gap between modern Conditional Access policies and applications that lack modern authentication support. By publishing the internal app through Application Proxy, the proxy acts as a front-end that can evaluate device compliance—such as requiring a PIN and encryption—before forwarding traffic to the legacy app, even though the app itself only uses legacy protocols. On the AZ-305 exam, this scenario tests your understanding of how to extend identity-driven security to non-modern apps without rewriting them; a common trap is choosing a VPN or direct network solution, which cannot enforce device compliance at the identity layer. Remember the mnemonic: “Proxy for legacy, policy for compliance”—if the app can’t talk modern auth, the proxy does the talking for it.
AZ-305 Practice Question: Design identity, governance, and monitoring solutions
This AZ-305 practice question tests your understanding of design identity, governance, and monitoring solutions. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. A key principle to apply: application Proxy publishes on-premises web apps securely to the internet.. 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.
A company uses Microsoft Entra ID (Microsoft Entra ID). They need to enforce that all users accessing the company's internal application from mobile devices must be compliant with device management policies (e.g., require a PIN and encryption). The application does not support modern authentication. Which Microsoft Entra ID feature should they use?

Correct answer & explanation
Microsoft Entra ID Application Proxy
Microsoft Entra ID Application Proxy is the correct choice because it enables secure remote access to on-premises web applications that do not support modern authentication. By publishing the internal application through Application Proxy, you can enforce device compliance policies (e.g., requiring a PIN and encryption) via Conditional Access policies applied to the Application Proxy service, even though the application itself uses legacy authentication.
Key principle: Application Proxy publishes on-premises web apps securely to the internet.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume Conditional Access alone can enforce device compliance on any application, but they miss the critical requirement that the application must support modern authentication; Application Proxy is the bridge that enables Conditional Access to work with legacy apps.
Detailed technical explanation
How to think about this question
Application Proxy works by installing a connector on-premises that establishes outbound connections to the Entra ID service, allowing users to access internal apps via the same Entra ID authentication and authorization policies. When Conditional Access policies are applied to the Application Proxy enterprise app, they evaluate device compliance before the request is forwarded to the on-premises application, effectively wrapping legacy apps with modern security controls. This approach is commonly used for apps like legacy SharePoint or custom line-of-business applications that cannot be updated to support modern authentication.
KKey Concepts to Remember
- Application Proxy publishes on-premises web apps securely to the internet.
- It provides Microsoft Entra ID pre-authentication for legacy applications.
- Conditional Access policies can be applied to apps published via Application Proxy.
- Application Proxy connectors are lightweight agents installed on-premises.
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
Application Proxy publishes on-premises web apps securely to the internet.
Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
