The answer is to use a startup script to download and set JAVA_HOME. This is correct because Azure App Service on Linux executes a startup script before the application launches, allowing you to dynamically download any custom JDK version and point the JAVA_HOME environment variable to it, effectively overriding the built-in Java stack without needing a custom container. On the Microsoft Azure Developer Associate AZ-204 exam, this scenario tests your understanding of App Service configuration flexibility and the distinction between platform-managed runtimes and user-controlled startup actions. A common trap is assuming a custom container is mandatory for non-standard runtimes, but the startup script approach is both simpler and cost-effective. Remember the mnemonic “Script, Not Ship” — you script the JDK download rather than shipping an entire container image.
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.
You are deploying a Java application to Azure App Service on Linux. The application requires a specific JDK version not available in the built-in stack. You need to provide the JDK without creating a custom container. What should you do?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use a startup script to download and set JAVA_HOME
Option C is correct because Azure App Service on Linux allows you to use a startup script to download a custom JDK and set the JAVA_HOME environment variable before the application starts. This approach avoids the need for a custom container while providing the specific JDK version required by the application.
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.
✗
Mount an Azure Files share containing the JDK
Why it's wrong here
Possible but not the simplest; also requires setting JAVA_HOME.
✗
Use the Azure App Service Windows stack with a custom JDK
Why it's wrong here
Question specifies Linux; Windows not desired.
✓
Use a startup script to download and set JAVA_HOME
Why this is correct
Startup command can install the JDK and set env.

✗
Create a custom Docker container and deploy to App Service
Why it's wrong here
Question says without creating a custom container.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may think mounting a file share (Option A) is the simplest way to provide custom binaries, but they overlook that App Service on Linux does not support mounting Azure Files for executable files, and the startup script approach is the documented method for custom runtimes.
Detailed technical explanation
How to think about this question
The startup script runs before the application starts and can use commands like `curl` or `wget` to download a JDK archive, extract it, and set `JAVA_HOME` and `PATH` environment variables. This leverages the App Service's built-in support for custom startup commands, which are executed in the same container as the application, ensuring the JDK is available for the Java runtime. In real-world scenarios, this is useful when using a specific JDK version required for compatibility with legacy libraries or performance tuning.
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.
