The answer is Azure Container Instances (ACI) because it is the only Azure service designed to run short-lived Linux containers without requiring any server or Kubernetes management. ACI launches a container on demand, executes the task—such as a 10-minute build pipeline job—and then stops, charging only for the exact seconds of compute time used. On the AZ-104 exam, this question tests your ability to differentiate between container orchestration options: ACI is for simple, ephemeral workloads, while Azure Kubernetes Service (AKS) is for complex, long-running clusters. A common trap is choosing AKS because it also runs containers, but the key phrase “without managing servers or a Kubernetes cluster” eliminates it. Remember the memory tip: “ACI for a quick CI”—if your container job is a one-off, short-lived task like a build or test, think ACI, not AKS.
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 must run a Linux container for about 10 minutes per request. The team does not want to manage servers or a Kubernetes cluster. Which Azure service should the administrator choose?
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 correct choice because it allows you to run a Linux container directly on Azure without managing any underlying servers or orchestrators. The 10-minute execution time fits perfectly within ACI's per-second billing model, and the service automatically starts and stops the container on demand, making it ideal for short-lived, ephemeral workloads like build pipeline tasks.
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 Container Instances
Why this is correct
Azure Container Instances runs containers on demand without managing servers or orchestration clusters.
Related concept
Read the scenario before looking for a memorised answer.
✗
Azure Virtual Machines
Why it's wrong here
VMs work, but they require more ongoing administration than a serverless container option.
✗
Azure App Service
Why it's wrong here
App Service is best for web apps and APIs, not arbitrary short-lived container jobs.
✗
Azure Kubernetes Service
Why it's wrong here
AKS is powerful, but it adds cluster management that the team does not want.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Azure Container Instances with Azure Kubernetes Service, assuming that any container workload requires an orchestrator, but ACI is purpose-built for simple, serverless container execution without cluster management.
Detailed technical explanation
How to think about this question
Under the hood, ACI uses a hypervisor-level isolation technology to launch containers directly on Azure infrastructure without a VM per container. This enables sub-minute startup times and per-second billing, which is critical for build pipelines that run intermittently. A real-world scenario is a CI/CD pipeline that compiles code or runs tests in a container; ACI can be invoked via the Azure CLI or REST API to spin up the container, execute the task, and then tear down, all without any persistent infrastructure.

→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.

Variation 1. A development team needs to run a Linux container for about 12 minutes each time a request is received. The team does not want to manage a server, cluster, or virtual machine. Which Azure service should the administrator use?
easy
A.Azure Kubernetes Service
✓ B.Azure Container Instances
C.Azure Virtual Machines
D.Azure App Service
Why B: Azure Container Instances (ACI) is the correct choice because it allows the team to run a Linux container directly in Azure without managing any underlying infrastructure, such as servers, clusters, or virtual machines. ACI is ideal for short-lived, event-driven workloads like this 12-minute request-based container, as it supports rapid startup and automatic shutdown, aligning with the 'serverless' requirement.
