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 deploy a container to Azure Container Instances (ACI). The container runs a background job that should automatically restart only if it exits with a non-zero exit code (i.e., crashes). You want to minimize costs. Which restart policy should you configure?

Clue words in this question

Noticing these words before you look at the options changes how you read each choice.

Clue: "minimum / minimize"
Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.

A
Set restart policy to Always and use a private container registry
Why wrong: The Always policy restarts the container even on successful exits, which is unnecessary for a background job and increases costs. A private registry is irrelevant to the restart behavior.
B
Set restart policy to OnFailure and use a single container group
OnFailure restarts only on crashes, and a single container group is the simplest and lowest-cost configuration.
C
Set restart policy to Never and use a public container registry
Why wrong: The Never policy does not restart the container if it crashes, which would require manual intervention.
D
Set restart policy to OnFailure and deploy in a virtual network
Why wrong: While OnFailure is correct, adding a virtual network is unnecessary for the restart behavior and increases complexity and cost.

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

✓

Set restart policy to OnFailure and use a single container group

The OnFailure restart policy restarts the container only when it exits with a non-zero exit code, which matches the requirement to restart only on crashes. This policy minimizes costs because the container does not run continuously when it exits successfully, unlike the Always policy. Using a single container group is the simplest and most cost-effective deployment for a single background job.

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.

✗
Set restart policy to Always and use a private container registry
Why it's wrong here
The Always policy restarts the container even on successful exits, which is unnecessary for a background job and increases costs. A private registry is irrelevant to the restart behavior.
✓
Set restart policy to OnFailure and use a single container group
Why this is correct
OnFailure restarts only on crashes, and a single container group is the simplest and lowest-cost configuration.

Why it's wrong here
The Never policy does not restart the container if it crashes, which would require manual intervention.

While OnFailure is correct, adding a virtual network is unnecessary for the restart behavior and increases complexity and cost.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates may confuse OnFailure with Always, thinking that any restart policy that restarts on failure must also restart on success, or they may over-engineer the solution by adding unnecessary features like a virtual network or private registry.

Detailed technical explanation

How to think about this question

Azure Container Instances supports three restart policies: Always, OnFailure, and Never. The OnFailure policy relies on the container's exit code; a non-zero exit code (typically 1-255) indicates a crash or error, triggering a restart, while exit code 0 means success and no restart. Under the hood, ACI uses the container's exit code from the init process (PID 1) to determine the restart action, and the container group's restart count is tracked in the container instance's properties.

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.
