Quick Answer

The answer is that the 'alwaysOn' setting is enabled but the App Service plan is on a tier that does not support Always On. This is because the Free and Shared pricing tiers lack the Always On feature, which is designed to keep your app loaded and prevent idle timeouts; only Basic, Standard, Premium, and Isolated tiers support it. When you set 'alwaysOn' to true on an unsupported tier, the setting is silently ignored, and the app pool recycles after a few minutes of inactivity, causing your .NET 6 web API to stop responding. On the AZ-204 exam, this tests your understanding of Azure App Service plan limitations and how configuration settings interact with pricing tiers—a common trap is assuming all ARM template properties are honored regardless of the plan. Remember the memory tip: "Always On needs a Basic foundation," meaning Always On requires at least a Basic tier to function.

AZ-204 Develop Azure compute solutions Practice Question

This AZ-204 practice question tests your understanding of develop azure compute solutions. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.

Exhibit

  "resources": [
    {
      "type": "Microsoft.Web/sites",
      "apiVersion": "2022-03-01",
      "name": "[parameters('siteName')]",
      "location": "[resourceGroup().location]",
      "properties": {

          "appSettings": [

              "value": "1"
            }
          ]
        }
      }
    }
  ]
}

Refer to the exhibit. You deploy this ARM template to create an Azure App Service. After deployment, the application stops responding after a few minutes. The application is a .NET 6 web API that runs in a Linux container. What is the most likely cause?

Clue words in this question

Noticing these words before you look at the options changes how you read each choice.

  • Clue: "most likely"

    Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.

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

✓

The 'alwaysOn' setting is enabled but the App Service plan is on a tier that does not support Always On.

Option B is correct. The template sets 'alwaysOn' to true, which keeps the app loaded even when idle. However, the Free and Shared pricing tiers do not support Always On; the feature is only available in Basic, Standard, Premium, and Isolated tiers. If the hosting plan is on a tier that doesn't support Always On, the setting is ignored, but more importantly, the app might be recycled due to idle timeout. The app stops responding, indicating that the app pool recycles. Option A is wrong because 'WEBSITE_RUN_FROM_PACKAGE' is valid. Option C is wrong because 'linuxFxVersion' is correct for .NET 6. Option D is wrong because the template is valid JSON.

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.

  • ✗

    The ARM template is missing the 'dependsOn' element.

    Why it's wrong here

    Not required; template deploys correctly.

  • ✗

    The 'linuxFxVersion' is set incorrectly for .NET 6.

    Why it's wrong here

    'DOTNETCORE|6.0' is correct for .NET 6 on Linux.

  • ✓

    The 'alwaysOn' setting is enabled but the App Service plan is on a tier that does not support Always On.

    Why this is correct

    Free/Shared tiers ignore Always On; app may be unloaded.

    Clue confirmation

    The clue word "most likely" in the question point toward this answer.

    Related concept

    Read the scenario before looking for a memorised answer.

  • ✗

    The 'WEBSITE_RUN_FROM_PACKAGE' app setting is incorrectly set to '1'.

    Why it's wrong here

    Valid setting; enables running from deployment package.

Common exam traps

Common exam trap: answer the scenario, not the keyword

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

How to think about this question

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.

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.
  • Use explanations to understand the rule behind the answer.

TExam Day Tips

  • Underline the problem statement mentally.
  • 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 startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
