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
Best answer
Microsoft Entra Application Proxy
Correct. Application Proxy provides secure remote access and SSO for on-premises web apps without needing a VPN.
B
Distractor review
Microsoft Entra Connect
Entra Connect synchronizes on-premises Active Directory identities to Microsoft Entra ID, but does not enable remote access to applications.
C
Distractor review
Microsoft Entra Domain Services
Domain Services provides managed domain services (e.g., domain join, group policy) for Azure VMs, not remote access to on-premises apps.
D
Distractor review
Microsoft Entra ID P2 license
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.
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.

It provides SSO for password-based, Kerberos, and header-based authentication methods, and eliminates the need for inbound VPN connections. Microsoft Entra Connect (Option B) syncs on-premises directories to Entra ID but does not provide remote access. Microsoft Entra Domain Services (Option C) provides managed domain services like domain join, not remote app access. Microsoft Entra ID P2 (Option D) is a license tier that includes features like Identity Protection, but is not a solution itself for remote app access.
