Quick Answer

The correct answer is that this configuration allows cross-origin requests from app.contoso.com and portal.contoso.com without credentials. This is because the ARM template snippet sets `allowedOrigins` to those two specific domains while explicitly setting `supportCredentials` to `false`. According to the CORS specification, when `supportCredentials` is false, the browser will permit the cross-origin HTTP requests from the listed origins, but it will not include any cookies, HTTP authentication headers, or client-side certificates in those requests, effectively treating them as anonymous. On the Microsoft Azure Developer Associate AZ-204 exam, this scenario tests your understanding of how CORS interacts with credential propagation in App Services, often appearing as a trap where candidates mistakenly assume that setting `allowedOrigins` alone implies credential support. A common memory tip is to think of `supportCredentials` as the "cookie gatekeeper": when it's false, the gate stays closed, so even though the origins are allowed through, no credentials can follow.

This AZ-204 practice question tests your understanding of develop azure compute solutions. 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.

        "https://portal.contoso.com"
      ],
      "supportCredentials": false
    }
  }
}
```

You find the above ARM template snippet in a deployment. What is the effect of this configuration on the App Service?

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

✓

Allows cross-origin requests from app.contoso.com and portal.contoso.com without credentials.

Option A is correct because the ARM template snippet sets `allowedOrigins` to specific domains (`app.contoso.com` and `portal.contoso.com`) and `supportCredentials` to `false`. This configuration allows cross-origin requests from those two origins but does not include credentials (cookies, HTTP authentication, or client-side certificates) in the requests, as per the CORS specification.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ✓

    Allows cross-origin requests from app.contoso.com and portal.contoso.com without credentials.

    Why this is correct

    CORS allows listed origins, and supportCredentials: false prevents credentials.

    Related concept

    Read the scenario before looking for a memorised answer.

  • ✗

    Configures the App Service to require authentication for cross-origin requests.

    Why it's wrong here

    CORS settings do not enforce authentication.

  • ✗

    Enables CORS for all origins by setting allowedOrigins to a wildcard.

    Why it's wrong here

    The snippet uses specific origins, not a wildcard.

  • ✗

    Blocks all cross-origin requests because supportCredentials is false.

    Why it's wrong here

    supportCredentials false does not block all origins.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates often confuse `supportCredentials: false` with blocking all cross-origin requests, when in fact it only disallows credentials while still allowing non-credentialed requests from the specified origins.

Detailed technical explanation

How to think about this question

Under the hood, the App Service CORS feature adds the `Access-Control-Allow-Origin` header to responses for allowed origins, and `supportCredentials` controls the `Access-Control-Allow-Credentials` header. When `supportCredentials` is `false`, the browser will not send credentials (e.g., cookies) with the cross-origin request, even if the origin is allowed. A real-world scenario is a public API that needs to be consumed by specific front-end apps without exposing user-specific data via cookies.

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.
