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. Microsoft Entra Application Proxy publishes on-premises web apps externally and provides secure remote access with single sign-on, eliminating the need for a VPN.
B
Distractor review
Microsoft Entra Self-Service Password Reset (SSPR)
SSPR allows users to reset their own forgotten passwords using verified methods, but it does not provide remote access to on-premises applications.
C
Distractor review
Microsoft Entra Privileged Identity Management (PIM)
PIM manages just-in-time and time-bound access to privileged roles in Azure AD, Azure, and other Microsoft services; it is not designed for general remote access to on-premises apps.
D
Distractor review
Microsoft Entra Identity Protection
Identity Protection detects and automates responses to identity-based risks using signals such as leaked credentials and anomalous sign-ins; it does not provide remote application access.
Common exam trap
Common exam trap: authentication is not authorization
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Technical deep dive
How to think about this question
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
KKey Concepts to Remember
- Authentication checks who the user is.
- Authorization controls what the user is allowed to do after login.
- Privilege levels affect access to EXEC and configuration commands.
- AAA, TACACS+ and RADIUS can separate login success from command access.
TExam Day Tips
- Do not assume successful login means full administrative access.
- Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
- Separate login problems from permission problems before choosing the answer.
