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.
A company uses Microsoft Entra ID. The IT team wants to provide remote employees with secure, single sign-on (SSO) access to a critical on-premises web application that uses password-based authentication, without requiring a VPN connection. Which Microsoft Entra ID feature should they use?
Correct. Application Proxy provides secure remote access and SSO for on-premises web apps without needing a VPN.
B
Microsoft Entra Connect
Why wrong: Entra Connect synchronizes on-premises Active Directory identities to Microsoft Entra ID, but does not enable remote access to applications.
C
Microsoft Entra Domain Services
Why wrong: Domain Services provides managed domain services (e.g., domain join, group policy) for Azure VMs, not remote access to on-premises apps.
D
Microsoft Entra ID P2 license
Why wrong: Entra ID P2 is a licensing plan that includes Identity Protection and Privileged Identity Management, but it is not a feature for remote app access.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Microsoft Entra Application Proxy
Microsoft Entra Application Proxy enables secure remote access to on-premises web applications by publishing them through an external endpoint, without requiring a VPN. It supports password-based SSO by securely storing and replaying credentials to the legacy application, allowing users to authenticate once via Entra ID. This makes it the correct choice for providing SSO to a password-based on-premises app without a VPN.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Microsoft Entra Connect (a sync tool) with Application Proxy, mistakenly thinking that syncing identities alone provides remote access and SSO to on-premises apps.
Detailed technical explanation
How to think about this question
Entra Application Proxy uses a connector agent installed on-premises that establishes outbound connections to the Entra ID cloud service, eliminating the need for inbound firewall ports. For password-based SSO, the proxy injects credentials into the application's login form using a browser extension or a dedicated credential store, which works with legacy apps that lack modern federation protocols like SAML or OIDC. This architecture ensures that remote users never directly connect to the internal network, maintaining security while enabling SSO.

→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.
