- A
The need for orchestration of multiple containers
ACI is suitable for single-container deployments or simple multi-container groups; AKS is better for complex orchestration.
- B
The restart policy for containers
ACI provides configurable restart policies (Always, OnFailure, Never), which is a factor for reliability.
- C
The need for GPU-accelerated compute
Why wrong: AKS supports GPU node pools, while ACI has limited GPU support; this is actually a factor, but the question asks for THREE correct factors; E is incorrect because it is a factor but the correct answer includes A, B, C.
- D
The availability of Azure Application Gateway Ingress Controller
Why wrong: Application Gateway Ingress Controller is a feature of AKS, but it is not a decision factor for choosing between ACI and AKS; ACI does not support it.
- E
The maximum resource limits per container instance
ACI has resource limits (e.g., 4 vCPUs, 16 GB memory per container group) that may not meet high-performance requirements.
Quick Answer
The answer is the maximum resource limits per container instance, along with orchestration complexity and scaling requirements. This is correct because Azure Container Instances (ACI) offers a simple, per-second billing model with fixed resource caps per container group, making it ideal for burstable or short-lived tasks, whereas Azure Kubernetes Service (AKS) provides full orchestration with dynamic scaling, service discovery, and load balancing across a cluster, handling complex multi-container workloads. On the Microsoft Azure Developer Associate AZ-204 exam, this question tests your ability to match workload characteristics to the right compute service—a common trap is choosing ACI for stateful or multi-service apps that actually need AKS’s orchestration. Remember the memory tip: “ACI for atomic, AKS for clusters”—if your workload needs more than a few containers or advanced scheduling, lean toward AKS.
AZ-204 Develop Azure compute solutions Practice Question
This AZ-204 practice question tests your understanding of develop azure compute solutions. 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.
Which THREE factors should you consider when choosing between Azure Container Instances (ACI) and Azure Kubernetes Service (AKS) for a containerized workload? (Choose three.)
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
The need for orchestration of multiple containers
Option A is correct because AKS provides full orchestration capabilities for managing multiple containers across a cluster, including service discovery, load balancing, and scaling. ACI is designed for single-container or simple multi-container groups without native orchestration, making AKS the appropriate choice when complex orchestration is required.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates mistakenly think GPU support is exclusive to AKS, but ACI also supports GPU-accelerated compute, making it a non-differentiating factor; similarly, the Application Gateway Ingress Controller is an AKS-only feature, so it is not a factor to 'consider when choosing' but rather a feature that only exists in one service.
Detailed technical explanation
How to think about this question
ACI's restart policy options (Always, OnFailure, Never) are applied at the container group level and determine behavior after container exit, whereas AKS uses pod restart policies (Always, OnFailure, Never) combined with controller-level strategies like ReplicaSet or StatefulSet. ACI's maximum resource limits per container instance (e.g., 4 vCPUs, 16 GB memory for Linux) are fixed by region and SKU, while AKS allows custom node sizes and resource quotas via Kubernetes resource requests and limits, offering greater flexibility for large workloads.
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
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.
