Question 1mediummultiple choice
Full question →mediummultiple choiceObjective-mapped
A company is developing a containerized microservices application. They want to minimize operational overhead for managing orchestration. The application has a low-to-medium traffic pattern that can spike unpredictably. They need fast scaling and pay-per-second billing. Which Azure compute service should they use?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
A
Azure Kubernetes Service (AKS) is a managed Kubernetes cluster but still requires monitoring and management of the cluster itself, adding operational overhead for a simple microservices app.
B
Best answer
B
Azure Container Instances (ACI) runs containers directly without orchestration, scales automatically in seconds, and bills per second, minimizing overhead.
C
Distractor review
C
Azure App Service supports containers but is designed for web applications and may not provide the same per-second billing and simplicity as ACI for generic container workloads.
D
Distractor review
D
Azure Virtual Machines with Docker require full OS and container management, which is high overhead and not recommended for minimizing operations.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

FAQ
Questions learners often ask
What does this AZ-305 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: B — Azure Container Instances (ACI) provides serverless containers without requiring any orchestration management. It scales quickly, offers per-second billing, and is ideal for simple, burstable workloads. Azure Kubernetes Service (AKS) provides full orchestration but requires cluster management, adding overhead. App Service supports containers but is more focused on web apps and may not offer the same per-second pricing. Running containers on VMs introduces significant management overhead.
