- A
Azure AD B2C (Business-to-Consumer).
Why wrong: Azure AD B2C is for customer-facing identity management, not for publishing internal applications. It does not proxy traffic to on-premises apps.
- B
Azure Application Gateway with Web Application Firewall (WAF).
Why wrong: Application Gateway is a Layer 7 load balancer that can handle public web traffic, but it does not provide Azure AD pre-authentication or the ability to connect to on-premises apps without a VPN. It requires the backend to be accessible.
- C
Azure AD Application Proxy.
Application Proxy is specifically designed for this scenario: it allows on-premises HTTP/HTTPS applications to be published through Azure AD, providing pre-authentication, MFA, and Conditional Access.
- D
Azure Front Door.
Why wrong: Azure Front Door is a global load balancer and CDN for web applications. It does not integrate with Azure AD pre-authentication by default and requires the backend to be publicly accessible or connected via private link, not suitable for on-premises apps without a VPN.
Quick Answer
The answer is Azure AD Application Proxy, which is the correct choice because it enables you to publish an on-premises web application to external users over the internet without requiring a VPN, while fully supporting Modern Authentication like Azure Multi-Factor Authentication and enforcing Conditional Access policies. This service works by installing a lightweight connector on your internal network that establishes an outbound-only connection to Azure AD, proxying traffic so that authentication and policy checks happen in the cloud before the request reaches the on-prem app—even for legacy applications that do not support SAML or OAuth. On the Microsoft Azure Security Engineer Associate AZ-500 exam, this scenario tests your understanding of secure remote access solutions; a common trap is confusing Application Proxy with Azure VPN Gateway or Azure Front Door, but remember that Application Proxy is specifically designed for legacy apps needing Modern Auth without network changes. A helpful memory tip: think of the connector as a “secure bridge” that lets Azure AD handle authentication first, so the app never sees unauthenticated traffic.
AZ-500 Manage identity and access Practice Question
This AZ-500 practice question tests your understanding of manage identity and access. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
A company has an on-premises web application that they want to expose to external users over the internet without requiring a VPN. External users must authenticate with Modern Authentication (e.g., using Azure Multi-Factor Authentication) and access policies must be enforced via Conditional Access. The application does not support SAML or OAuth. Which Azure service should they use to publish this application securely?
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
Azure AD Application Proxy.
Azure AD Application Proxy is the correct choice because it allows publishing on-premises web applications to external users without requiring a VPN, supports Modern Authentication (including Azure MFA), and enforces Conditional Access policies. It works by installing a connector on-premises that proxies traffic through Azure AD, enabling authentication and policy enforcement even for legacy applications that do not support SAML or OAuth.
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.
- ✗
Azure AD B2C (Business-to-Consumer).
Why it's wrong here
Azure AD B2C is for customer-facing identity management, not for publishing internal applications. It does not proxy traffic to on-premises apps.
- ✗
Azure Application Gateway with Web Application Firewall (WAF).
Why it's wrong here
Application Gateway is a Layer 7 load balancer that can handle public web traffic, but it does not provide Azure AD pre-authentication or the ability to connect to on-premises apps without a VPN. It requires the backend to be accessible.
- ✓
Azure AD Application Proxy.
- ✗
Azure Front Door.
Why it's wrong here
Azure Front Door is a global load balancer and CDN for web applications. It does not integrate with Azure AD pre-authentication by default and requires the backend to be publicly accessible or connected via private link, not suitable for on-premises apps without a VPN.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Azure AD Application Proxy with Azure Application Gateway, assuming that WAF provides authentication, but Application Gateway does not integrate with Azure AD for Modern Authentication or Conditional Access enforcement.
Detailed technical explanation
How to think about this question
Azure AD Application Proxy uses a lightweight connector service installed on-premises that establishes outbound connections to Azure AD, eliminating the need for inbound firewall rules. The connector forwards requests to the internal application, while Azure AD handles pre-authentication using Modern Authentication (OAuth 2.0/OpenID Connect) and enforces Conditional Access policies before the request reaches the connector. This architecture allows legacy applications that only support Integrated Windows Authentication (IWA) or header-based authentication to be secured with MFA and access policies without modifying the application code.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
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
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 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.
