AZ-104 Deploy and Manage Azure Compute Practice Question
This AZ-104 practice question tests your understanding of deploy and manage azure compute. 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.
A build pipeline starts a containerized data-processing job every evening. Each run finishes in under 20 minutes, does not need persistent servers, and never receives inbound traffic. Which compute service best fits this workload?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Clue: "never"
Why it matters: Absolute qualifier. True only if the statement has zero exceptions — be cautious of options that seem obvious but break down in edge cases.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Azure Container Instances
Azure Container Instances (ACI) is the best fit because it allows you to run a containerized job directly in Azure without provisioning or managing any underlying infrastructure. The workload is short-lived (under 20 minutes), requires no persistent servers, and has no inbound traffic, which aligns perfectly with ACI's pay-per-second billing and ability to start containers on demand from a build pipeline.
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.
✗
Azure App Service
Why it's wrong here
App Service is intended for continuously running web apps, not short-lived batch containers.
✓
Azure Container Instances
Why this is correct
Azure Container Instances is designed for on-demand container execution without managing a cluster or servers.
Clue confirmation
The clue words "best", "never" in the question point toward this answer.

✗
Azure Virtual Machines
Why it's wrong here
Virtual machines would add unnecessary patching and infrastructure management for a short batch workload.
✗
Azure Kubernetes Service
Why it's wrong here
AKS is appropriate for orchestrated container platforms, but it is too much overhead for this simple job.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often choose Azure Kubernetes Service (D) because they associate containers with Kubernetes, overlooking that ACI is the simpler, more cost-effective solution for single, short-lived containerized jobs without orchestration needs.
Detailed technical explanation
How to think about this question
Under the hood, Azure Container Instances uses a hypervisor-level isolation technology similar to Hyper-V containers, ensuring each container group runs in its own security boundary. ACI supports direct integration with Azure Container Registry (ACR) and can be triggered via Azure CLI, PowerShell, or SDK, making it ideal for CI/CD pipelines where a container is spun up, executes a task, and is torn down automatically. A real-world scenario is a nightly ETL job that processes logs into a data warehouse, where ACI eliminates the need to maintain a cluster and reduces costs by only charging for the seconds the container runs.

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.
