Question 1easymultiple choice
Full question →easymultiple choiceObjective-mapped
A company has multiple on-premises web applications that need to be securely published for remote employees. The company uses Azure AD for identity management and wants to apply Conditional Access policies, including multi-factor authentication, to these applications. The security team wants to avoid exposing the on-premises infrastructure to the internet directly. Which Azure service should they deploy to meet these requirements?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
Azure Application Gateway
Application Gateway is a web traffic load balancer that can expose on-premises apps only if they are reachable from Azure, typically via a VPN or ExpressRoute, and it requires custom configuration for Azure AD authentication.
B
Distractor review
Azure Front Door
Front Door is a global load balancer for HTTP/S traffic, but it does not natively connect to on-premises applications; it typically fronts Azure-hosted or directly exposed endpoints.
C
Best answer
Azure AD Application Proxy
Azure AD Application Proxy publishes on-premises web applications externally with Azure AD pre-authentication, allowing integration with Conditional Access policies and MFA without exposing the on-premises network.
D
Distractor review
Azure VPN Gateway
VPN Gateway secures traffic between on-premises and Azure but does not provide the application-layer publishing features or Azure AD integration for web applications.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

FAQ
Questions learners often ask
What does this AZ-500 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Azure AD Application Proxy — Azure AD Application Proxy provides secure remote access to on-premises web applications without requiring a VPN. It acts as a reverse proxy, terminating the connection from the user and creating a separate connection to the on-premises app. It integrates with Azure AD for authentication and can be used with Conditional Access policies to require MFA. Azure Application Gateway can expose on-premises apps only if they are migrated to Azure or via site-to-site VPN, but it doesn't natively integrate with Azure AD pre-authentication without additional configuration. Azure Front Door is for global HTTP load balancing and acceleration, not for publishing private on-premises apps. Azure VPN Gateway creates a VPN connection, but it doesn't provide the same seamless integration with Azure AD pre-authentication and Conditional Access as Application Proxy.
