- A
Azure App Service Authentication (EasyAuth) with Microsoft Entra ID as identity provider.
EasyAuth integrates with Microsoft Entra ID and other providers, automatically handling token validation and session management, requiring no code changes.
- B
IP restrictions in the app’s web.config.
Why wrong: IP restrictions control access based on network addresses, not user identity; they do not authenticate users.
- C
Client certificate authentication.
Why wrong: Client certificates require application code to validate certificates and are not a built-in no-code solution for Microsoft Entra ID authentication.
- D
Shared access signatures (SAS) for the app URL.
Why wrong: SAS tokens are used for Azure Storage access, not for authenticating users to a web application.
AZ-204 Implement Azure security Practice Question
This AZ-204 practice question tests your understanding of implement azure security. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
Your company uses Azure App Service to host a web application. You need to allow only authenticated users from your Microsoft Entra ID tenant to access the app, without writing any authentication code. Which feature should you configure?
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 App Service Authentication (EasyAuth) with Microsoft Entra ID as identity provider.
Azure App Service Authentication (EasyAuth) is the correct feature because it provides a built-in, code-free way to authenticate users by integrating with Microsoft Entra ID (formerly Azure AD). When configured, the App Service automatically validates tokens and redirects unauthenticated users to the identity provider, enforcing authentication at the platform level without requiring any changes to the application code.
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 network-level access controls (like IP restrictions) with identity-based authentication, or mistakenly think SAS tokens can secure a web app URL, when in fact SAS are strictly for Azure Storage access and have no role in user authentication for App Service.
Detailed technical explanation
How to think about this question
Under the hood, EasyAuth works by intercepting all incoming HTTP requests at the App Service front-end layer (the 'front end' role). It redirects unauthenticated requests to the Microsoft Entra ID login endpoint, handles the OAuth 2.0 authorization code flow, and injects the resulting identity claims into HTTP headers (e.g., X-MS-CLIENT-PRINCIPAL-NAME) that the application can read without writing authentication logic. A subtle behavior is that EasyAuth can also be configured to allow anonymous requests while still populating claims for authenticated users, enabling a hybrid approach.
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.
