The correct answer is Azure Kubernetes Service (AKS) and Azure Application Gateway. AKS orchestrates Linux containers and supports horizontal pod autoscaling, which can automatically scale container replicas based on HTTP traffic metrics like request rate or latency. The Application Gateway acts as a Layer-7 load balancer, terminating HTTP traffic and routing it to the AKS cluster, enabling fine-grained scaling decisions tied directly to web traffic patterns. On the AZ-305 exam, this scenario tests your ability to choose services for a highly available, scalable containerized web app—a common design pattern for the “Design for high availability” and “Design for scalability” domains. A frequent trap is selecting Azure Load Balancer (Layer-4) or Azure Container Instances (no orchestration), but remember: HTTP-aware scaling requires a Layer-7 ingress controller and an orchestrator. Memory tip: “AKS + App Gateway = HTTP scale on autopilot.”
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.
Which TWO services should you use to design a highly available and scalable web application on Azure that runs on Linux containers and requires automatic scaling based on HTTP traffic? (Choose two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Azure Application Gateway
A and D are correct. Azure Kubernetes Service (AKS) orchestrates containers and supports horizontal pod autoscaling based on HTTP traffic. Azure Application Gateway acts as a load balancer and can route traffic to AKS. B is wrong because Azure Container Instances is for simple container deployments without orchestration. C is wrong because Azure Load Balancer is for TCP/UDP traffic, not HTTP-specific scaling. E is wrong because Azure Web App for Containers does not support automatic scaling based on HTTP traffic as granularly as AKS.
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
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
