AZ-104 Deploy and Manage Azure Compute Practice Question

This AZ-104 practice question tests your understanding of deploy and manage azure compute. 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.

A container group runs a one-time import job that writes data to an external system. If the job succeeds, the container must stop and stay stopped. If the job fails, it should automatically retry by restarting. Which restart policy should the administrator choose?

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

OnFailure

The OnFailure restart policy is correct because it instructs Azure Container Instances (ACI) to restart the container only when the process exits with a non-zero exit code, indicating failure. For a one-time import job that must stop permanently on success (exit code 0) and retry on failure, OnFailure matches this exact behavior without unnecessary restarts.

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.

  • Always

    Why it's wrong here

    Always restarts the container regardless of success or failure. That would cause a completed import job to start again even after successful completion, which is not the requirement.

    When this WOULD be correct

    For a long-running service like a web server or a background worker that must be kept running continuously, such as a container hosting an API that should restart after any crash or stop to maintain availability.

  • Never

    Why it's wrong here

    Never prevents any restart behavior. That means a failed job would not retry automatically, which conflicts with the requirement to restart on failure.

    When this WOULD be correct

    If the question stated that the container should run exactly once and never be restarted under any circumstances (e.g., a data export that must not duplicate records), then 'Never' would be correct.

  • OnFailure

    Why this is correct

    OnFailure matches a batch-style workload that should retry after an error but remain stopped after a successful run. It allows the container group to restart when the process exits unsuccessfully while avoiding unnecessary reruns after completion.

    Related concept

    Read the scenario before looking for a memorised answer.

  • Manual

    Why it's wrong here

    Manual is not the standard ACI restart policy for an unattended job. It would leave the workload dependent on operator action instead of automatically retrying on failure.

    When this WOULD be correct

    In a scenario where a container group runs a batch job that must be manually monitored and restarted by an administrator after failure, and the environment does not support automatic restart policies, a 'Manual' policy would be correct. For example, in a custom orchestration system where the container is expected to exit and be restarted only via external triggers.

Option-by-option analysis

Why each answer is right or wrong

Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The AZ-104 exam frequently reuses these exact scenarios with slightly different constraints.

OnFailureCorrect answer

Why this is correct

OnFailure matches a batch-style workload that should retry after an error but remain stopped after a successful run. It allows the container group to restart when the process exits unsuccessfully while avoiding unnecessary reruns after completion.

AlwaysWrong answer — click to see why

Why this is wrong here

The 'Always' policy restarts the container regardless of exit code, so even after a successful job completion, the container would restart, preventing it from staying stopped as required.

★ When this WOULD be the correct answer

For a long-running service like a web server or a background worker that must be kept running continuously, such as a container hosting an API that should restart after any crash or stop to maintain availability.

Why candidates choose this

Candidates may confuse a one-time job with a service that needs high availability, assuming that any stop is a failure and should be restarted, overlooking the requirement to stop on success.

NeverWrong answer — click to see why

Why this is wrong here

The 'Never' restart policy means the container will never be restarted, even if the job fails. Since the requirement is to automatically retry on failure, 'Never' does not satisfy the retry condition.

★ When this WOULD be the correct answer

If the question stated that the container should run exactly once and never be restarted under any circumstances (e.g., a data export that must not duplicate records), then 'Never' would be correct.

Why candidates choose this

Candidates might think 'Never' is appropriate because the container should stop after success, but they overlook the need for automatic retry on failure.

ManualWrong answer — click to see why

Why this is wrong here

The 'Manual' restart policy is not a valid option for Azure Container Instances; the available policies are Always, Never, and OnFailure. Therefore, it cannot be selected for any restart behavior.

★ When this WOULD be the correct answer

In a scenario where a container group runs a batch job that must be manually monitored and restarted by an administrator after failure, and the environment does not support automatic restart policies, a 'Manual' policy would be correct. For example, in a custom orchestration system where the container is expected to exit and be restarted only via external triggers.

Why candidates choose this

Candidates may mistakenly think 'Manual' is a valid Azure Container Instances restart policy, confusing it with other Azure services like Azure Container Apps or Docker Compose where manual restart is an option.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates often confuse 'OnFailure' with 'Always' for retry scenarios, not realizing that 'Always' restarts even after success, which would break the 'stop on success' requirement.

Detailed technical explanation

How to think about this question

Under the hood, ACI evaluates the container's exit code against the restart policy: exit code 0 triggers no restart under OnFailure, while any non-zero exit code triggers a restart with exponential backoff (up to 5 retries by default). In real-world scenarios, this policy is ideal for batch jobs or ETL processes where idempotency is ensured, as it avoids infinite loops from successful runs while providing automatic fault recovery.

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.
