AZ-204 Develop Azure compute solutions Practice Question
This AZ-204 practice question tests your understanding of develop azure compute solutions. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
Refer to the exhibit. You deploy this ARM template to a resource group. The template fails with a 'ResourceNotFound' error. 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 the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The App Service plan 'myplan' does not exist in the resource group.
The ARM template references an App Service plan named 'myplan' in the 'serverFarmId' property of the Microsoft.Web/sites resource. If 'myplan' does not exist in the same resource group, the deployment fails with a 'ResourceNotFound' error because Azure Resource Manager cannot resolve the dependency on a non-existent resource. The template does not include a definition for the App Service plan, so it must already exist in the resource group.
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 Service plan 'myplan' does not exist in the resource group.
Why this is correct
The plan must exist or be defined in the template.
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 'apiVersion' is incorrect.
Why it's wrong here
The apiVersion is valid.
✗
The template is missing the 'dependsOn' property.
Why it's wrong here
Missing dependsOn may cause ordering issues but not ResourceNotFound.
✗
The 'type' property is incorrect for a web app.
Why it's wrong here
The type is correct.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Microsoft often tests the distinction between a missing resource and a missing dependency; the trap here is that candidates assume a 'ResourceNotFound' error always means a missing 'dependsOn' property, when in fact it indicates the referenced resource does not exist at all.
Detailed technical explanation
How to think about this question
Under the hood, Azure Resource Manager evaluates the 'serverFarmId' property as a resource reference. If the referenced App Service plan does not exist, the deployment engine throws a 'ResourceNotFound' exception during validation. This behavior is distinct from missing 'dependsOn', which only affects ordering, not existence. In real-world scenarios, this often occurs when deploying a web app to a shared or pre-existing plan without ensuring the plan is deployed first or already present.
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.

What is the correct answer to this question?
The correct answer is: The App Service plan 'myplan' does not exist in the resource group. — The ARM template references an App Service plan named 'myplan' in the 'serverFarmId' property of the Microsoft.Web/sites resource. If 'myplan' does not exist in the same resource group, the deployment fails with a 'ResourceNotFound' error because Azure Resource Manager cannot resolve the dependency on a non-existent resource. The template does not include a definition for the App Service plan, so it must already exist in the resource group.
