AZ-104 ACI offers serverless container execution. 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. A key principle to apply: aCI offers serverless container execution.. 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 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?
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 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.
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Azure Kubernetes Service
Why it's wrong here
AKS is useful for container orchestration, but it adds cluster management overhead.
✓
Azure Container Instances
Why this is correct
ACI runs containers directly without managing servers or a Kubernetes cluster.
Related concept
ACI offers serverless container execution.
✗
Azure Virtual Machines
Why it's wrong here
A VM would require operating system administration and ongoing server management.
✗
Azure App Service
Why it's wrong here
App Service is best for web apps, not for a simple one-off container runtime.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often choose Azure Kubernetes Service (AKS) because they associate containers with Kubernetes, but the question explicitly prohibits managing a cluster, making ACI the only serverless container option that meets the 'no management' requirement.
Detailed technical explanation
How to think about this question
Azure Container Instances uses a hypervisor-level isolation technology that launches containers directly on Azure's infrastructure, with startup times often under 5 seconds. Under the hood, ACI leverages a container group model where containers share a lifecycle, network, and storage, and it supports a 'restart policy' of 'Never' to ensure the container runs once and stops, ideal for batch or event-driven tasks. In a real-world scenario, this is commonly used for processing messages from Azure Queue Storage or Event Grid, where each message triggers a container that runs and then terminates, minimizing costs.
KKey Concepts to Remember
ACI offers serverless container execution.
ACI eliminates the need to manage VMs or orchestrators.
ACI is ideal for burstable, short-lived, or event-driven workloads.
ACI charges per second for container runtime.
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
ACI offers serverless container execution.
Real-world example
How this comes up in practice
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
