Develop Azure compute solutions →hardMultiple ChoiceObjective-mapped

Quick Answer

The answer is that the WEBSITE_RUN_FROM_PACKAGE setting must be set to the blob URL, not to '1', because the value '1' tells Azure App Service to use a local package stored in the site’s wwwroot folder rather than an external URL. When you deploy a new ZIP package to Azure Blob Storage and update the setting with the new URL, the service ignores that URL if the value remains '1', continuing to run the old local package instead. On the AZ-204 exam, this tests your understanding of how App Service retrieves application code—specifically the difference between local storage and external blob storage for run-from-package deployments. A common trap is assuming any non-empty value triggers an update, but '1' is a reserved constant for local packages. Remember the mnemonic: "One is local, URL is global"—if you see '1', the service stays home; only a full blob URL forces it to fetch the new code.

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

Refer to the exhibit.

```json
{
  "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
  "contentVersion": "1.0.0.0",
  "parameters": {
    "webAppName": {
      "type": "string",
      "defaultValue": "myWebApp"
    }
  },
  "resources": [
    {
      "type": "Microsoft.Web/sites",
      "apiVersion": "2022-09-01",
      "name": "[parameters('webAppName')]",
      "location": "[resourceGroup().location]",
      "properties": {
        "siteConfig": {
          "appSettings": [
            {
              "name": "WEBSITE_RUN_FROM_PACKAGE",
              "value": "1"
            }
          ]
        }
      }
    }
  ]
}
```

You deploy the above ARM template. Later, you update the web app's code by deploying a new ZIP package to Azure Blob Storage and updating the WEBSITE_RUN_FROM_PACKAGE setting with the new package URL. However, the web app continues to run the old code. 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 value '1' indicates the package is from local storage, not an external URL.

Option D is correct because when the WEBSITE_RUN_FROM_PACKAGE app setting is set to '1', it tells Azure App Service to use a local package stored in the site's wwwroot folder. To use an external package from Azure Blob Storage, the setting must be set to the full URL of the blob (with a SAS token if private). Keeping the value as '1' means the service ignores the new blob URL and continues to run the old local package.

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 app setting name is misspelled. It should be 'WEBSITE_RUN_FROM_ZIP'.

    Why it's wrong here

    The correct setting name is WEBSITE_RUN_FROM_PACKAGE.

  • ✗

    The setting requires a value of '0' to enable external packages.

    Why it's wrong here

    Value '0' disables the feature.

  • ✗

    The ARM template uses an incorrect apiVersion.

    Why it's wrong here

    The apiVersion is valid and does not affect the setting interpretation.

  • ✓

    The value '1' indicates the package is from local storage, not an external URL.

    Why this is correct

    A value of '1' means the package is already deployed locally. To use a URL, set the value to the URL directly.

    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.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates assume setting the value to '1' is a generic 'enable' flag, not realizing it has a specific meaning (local package) and that external packages require the full URL as the setting value.

Detailed technical explanation

How to think about this question

Under the hood, when WEBSITE_RUN_FROM_PACKAGE is set to '1', Azure App Service extracts the package from the local D:\home\data\SitePackages folder. For external URLs, the setting must be a direct HTTPS URL to the blob, and the service downloads and caches the package at startup. A common subtlety is that changing the setting value to a new URL does not automatically trigger a restart; you must restart the app or use the 'sync' operation to force re-download.

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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
