AZ-204 Develop Azure compute solutions Practice Question
This AZ-204 practice question tests your understanding of develop azure compute solutions. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The server farm resource (Microsoft.Web/serverfarms) is not defined in the template
The error 'The serverFarmId property is required' indicates that the ARM template is missing a reference to an App Service Plan (Microsoft.Web/serverfarms) resource. In Azure, a web app or function app must be associated with an App Service Plan, which defines the compute resources and pricing tier. The template must define the server farm resource and link it via the 'serverFarmId' property on the site resource.
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 server farm resource (Microsoft.Web/serverfarms) is not defined in the template
Why this is correct
The template references a server farm that is not defined, causing the error.
Related concept
Read the scenario before looking for a memorised answer.
✗
The 'location' property is missing from the site resource
Why it's wrong here
The location property is present: "[resourceGroup().location]".
✗
The apiVersion should be '2018-02-01'
Why it's wrong here
apiVersion '2022-09-01' is valid.
✗
The 'kind' property should be 'functionapp'
Why it's wrong here
'app' is a valid kind for a web app.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often think the error is about a missing property on the site resource itself (like location or kind), rather than realizing the entire server farm resource definition is absent from the template.
Detailed technical explanation
How to think about this question
Under the hood, the ARM template's 'dependsOn' element and 'serverFarmId' property create an explicit dependency between the site resource and the server farm resource. The serverFarmId must be set to the resource ID of the Microsoft.Web/serverfarms resource, typically using the format '[resourceId('Microsoft.Web/serverfarms', parameters('hostingPlanName'))]'. In real-world scenarios, forgetting to include the server farm resource is common when copying templates from documentation that only shows the site resource snippet.
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 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.
