Quick Answer
The answer is the Client ID, Issuer URL, and Allowed Token Audiences. The Client ID uniquely identifies your application registration to Microsoft Entra ID, while the Issuer URL tells App Service where to fetch and validate the signing keys for incoming tokens. The Allowed Token Audiences ensure that the token was issued specifically for your app, preventing token replay across different applications. On the AZ-204 exam, this tests your understanding of the App Service Authentication configuration components as a three-part trust relationship between the app, the identity provider, and the token itself. A common trap is confusing the Client Secret (optional for implicit flows) or the Tenant ID (which is already embedded in the Issuer URL) as required fields. Remember the memory tip: “ID, URL, Audience” — the app’s identity, the issuer’s location, and the token’s intended recipient.
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 application uses Azure App Service and needs to authenticate users via Microsoft Entra ID. Which THREE components must be configured in the App Service authentication settings?
Client ID
Required to identify the application.
Allowed token audiences
Ensures the token is intended for this app.
Issuer URL
Required to validate token issuer.
Client secret
Why wrong: Not required if using client credentials flow or other methods.
Tenant ID
Why wrong: Tenant ID is part of the issuer URL.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Client ID
Option A is correct because the client ID identifies the application to Entra ID. Option B is correct because the issuer URL tells App Service where to validate tokens. Option D is correct because allowed token audiences ensure the token is intended for this app. Option C is wrong because client secret is optional for some flows. Option E is wrong because tenant ID is part of the issuer URL.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.

Same concept, more angles
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. You deploy a web application in Azure App Service. You need to authenticate users via Microsoft Entra ID (Microsoft Entra ID) with minimal custom code. Which App Service feature should you configure?
mediumWhy A: App Service Authentication (also known as Easy Auth) is the correct choice because it provides a turnkey authentication layer that integrates directly with Microsoft Entra ID. It requires minimal custom code by handling the OAuth 2.0 authorization code flow, token validation, and session management at the App Service platform level, allowing you to simply configure the identity provider in the Azure portal.
Variation 2. Your application uses Azure App Service and needs to authenticate users via Microsoft Entra ID. You want to minimize code changes. Which feature should you use?
easyWhy C: App Service Authentication (Easy Auth) provides built-in authentication with Microsoft Entra ID without requiring code changes. Option A is correct. Option B is wrong because Microsoft.Identity.Web requires code changes. Option C is wrong because MSAL requires code. Option D is wrong because Azure AD B2C is for external identities.
