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.
You are deploying an application to Azure App Service that requires a custom startup script to initialize the environment. Where should you place the startup script in the application code?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
As a startup command in the App Service configuration
Option D is correct because Azure App Service allows you to specify a custom startup command or script in the App Service configuration (under 'General settings' or via the Azure CLI with `--startup-file`). This startup command runs before the application starts, enabling you to initialize the environment, run pre-deployment tasks, or set up dependencies. Placing the startup script in the configuration ensures it is executed by the App Service platform, which handles the runtime environment (Windows or Linux) and integrates with the application lifecycle.
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.
✗
In the 'web.config' file
Why it's wrong here
web.config is for IIS configuration, not for running arbitrary startup scripts.
✗
In a 'docker-compose.yml' file
Why it's wrong here
docker-compose is used for multi-container apps, not for custom startup scripts in App Service.
✗
In the root of the application code as 'startup.sh'
Why it's wrong here
App Service does not automatically run a startup script; it must be specified in the configuration.
✓
As a startup command in the App Service configuration
Why this is correct
You can set the startup command (e.g., 'dotnet myapp.dll' or a script path) in the Azure portal or CLI.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates assume placing a script file in the application root is sufficient for execution, but Azure App Service requires explicit configuration to designate a startup file or command, as the platform does not automatically scan for or execute arbitrary scripts.
Detailed technical explanation
How to think about this question
Under the hood, Azure App Service on Linux uses a containerized environment based on the chosen runtime stack (e.g., Node.js, Python, .NET Core). When you specify a startup command, it is passed as the `CMD` instruction to the underlying container, overriding the default entry point. For Windows App Service, the startup command can be a PowerShell script or an executable, and it runs as part of the site initialization process before the application pool starts. A subtle behavior is that the startup script must be accessible within the application's `/home/site/wwwroot` directory (or a subpath) and must have execute permissions; otherwise, the script will fail silently.

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.
