- A
Azure Container Apps
Azure Container Apps is a serverless platform for running containers. It provides automatic scaling based on HTTP traffic or events, built-in load balancing, and supports rolling updates via revisions. It abstracts away underlying infrastructure, so no VMs to manage.
- B
Azure Container Instances
Why wrong: Azure Container Instances launches individual containers quickly but does not provide automatic scaling, load balancing, or rolling updates for microservices deployments.
- C
Azure Batch
Why wrong: Azure Batch is for running large-scale parallel and HPC workloads, not for managing containerized microservices with rolling updates.
- D
Azure Functions
Why wrong: Azure Functions is a serverless compute service for event-driven functions, not designed for running containerized microservices.
Quick Answer
Azure Container Apps is the correct choice because it delivers a fully managed serverless platform for running containerized microservices with auto scaling, eliminating the need to manage virtual machines while supporting built-in load balancing via Envoy and rolling updates with revision management for zero-downtime deployments. This solution directly meets the requirement for a fully managed containerized microservices environment that automatically scales based on HTTP traffic or events, making it distinct from Azure Kubernetes Service, which still requires cluster management. On the AZ-305 exam, this question tests your ability to differentiate between Azure’s container services—a common trap is choosing Azure Kubernetes Service for its orchestration power, but the key phrase “without managing virtual machines” points to the serverless nature of Container Apps. Remember the mnemonic “CAMS” for Container Apps: Containerized, Auto-scaling, Managed, Serverless—if the scenario emphasizes zero infrastructure overhead and event-driven scaling, Container Apps is your answer.
AZ-305 Design infrastructure solutions Practice Question
This AZ-305 practice question tests your understanding of design infrastructure 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.
A company wants to deploy containerized microservices on Azure without managing virtual machines. The solution must support automatic scaling based on demand, built-in load balancing, rolling updates for zero-downtime deployments, and a fully managed platform. Which Azure compute service should they choose?

Correct answer & explanation
Azure Container Apps
Azure Container Apps is the correct choice because it provides a fully managed, serverless platform for running containerized microservices without managing virtual machines. It supports automatic scaling based on HTTP traffic or events, built-in load balancing via Envoy, and rolling updates with revision management to ensure zero-downtime deployments. This aligns perfectly with the requirement for a fully managed platform that abstracts away infrastructure.
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 often confuse Azure Container Instances (ACI) with a managed orchestration solution, but ACI lacks the automatic scaling, load balancing, and rolling update capabilities that Container Apps provides for microservices.
Detailed technical explanation
How to think about this question
Under the hood, Azure Container Apps leverages the open-source Kubernetes Event-Driven Autoscaling (KEDA) for scaling based on demand and Envoy as a sidecar proxy for built-in load balancing and traffic splitting. It also uses Azure Container Registry (ACR) for image storage and supports revision-level traffic management, allowing you to gradually shift traffic during rolling updates. A subtle behavior is that Container Apps abstracts Kubernetes entirely, so you cannot directly manage pods or nodes, which is ideal for teams wanting to avoid operational overhead.
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.
