AZ-204 Develop Azure compute solutions Practice Question

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.

Exhibit

{
  "type": "Microsoft.Web/sites/slots",
  "apiVersion": "2022-03-01",
  "name": "[concat(parameters('siteName'), '/', parameters('slotName'))]",
  "location": "[resourceGroup().location]",
  "properties": {
    "serverFarmId": "[parameters('hostingPlanId')]",
    "siteConfig": {
      "appSettings": [
        {
          "name": "DEPLOYMENT_SLOT",
          "value": "[parameters('slotName')]"
        }
      ]
    }
  }
}

Refer to the exhibit. You are deploying this ARM template to create a deployment slot for an Azure App Service. The template deploys successfully. However, the slot-specific app setting 'DEPLOYMENT_SLOT' is not visible in the Azure portal under the slot's Configuration > Application settings. 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 template does not set 'slotSticky' to true for the app setting

Option B is correct because in ARM templates, app settings are made slot-specific (sticky) by setting the 'slotSticky' property to true. Without this property, the setting is treated as a regular, non-sticky app setting that is not pinned to the deployment slot, so it will not appear under the slot's Configuration > Application settings in the Azure portal.

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.

  • ✗

    Slot settings are not supported in ARM templates

    Why it's wrong here

    Wrong: They are supported.

  • ✓

    The template does not set 'slotSticky' to true for the app setting

    Why this is correct

    Correct: Without slotSticky, the setting is not pinned to the slot.

    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.

  • ✗

    Deployment slots have been deprecated for App Service

    Why it's wrong here

    Wrong: They are still fully supported.

  • ✗

    The app setting name must be prefixed with 'APPSETTING_'

    Why it's wrong here

    Wrong: App settings in App Service do not require a prefix.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates assume all app settings defined in a slot's ARM template are automatically slot-sticky, but Azure requires explicit declaration via the 'slotSticky' property to make them deployment-slot-specific.

Detailed technical explanation

How to think about this question

Under the hood, slot-sticky settings are stored in the slot's configuration blob and are not swapped when a slot swap occurs. The 'slotSticky' property in the ARM template maps to the 'sticky' flag in the Azure Resource Manager API. A real-world scenario is when you need to keep a database connection string or a deployment slot name constant across swaps; failing to set 'slotSticky' to true means the setting will be overwritten during a swap, defeating the purpose of slot-specific configuration.

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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
