A company wants to run a containerized microservices application on Azure. They need automatic scaling based on demand, service discovery, and rolling updates without manual intervention. They want to avoid managing the underlying virtual machines. Which Azure compute service should they choose?
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
Azure Container Instances (ACI)
ACI runs individual containers quickly but does not provide orchestration features like automatic scaling, service discovery, or rolling updates.
B
Best answer
Azure Kubernetes Service (AKS)
AKS is a managed Kubernetes service that offers full container orchestration, including scale, service discovery, rolling updates, and manages the underlying VMs for you.
C
Distractor review
Azure App Service
App Service can host web apps and APIs but is not designed for container orchestration; it uses a container runtime but lacks native Kubernetes capabilities.
D
Distractor review
Azure Functions
Functions is for event-driven, serverless code snippets, not for managing a set of microservices with orchestration requirements.
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.

Question 1
A developer is building a serverless application that requires integration with an on-premises SQL Server database for real-time data processing. The on-premises network is connected to Azure via a site-to-site VPN. Which Azure service would allow the function to securely access the on-premises database without exposing it to the public internet?
Question 2
A solutions architect is designing a storage solution for a large media company. The company needs to store video files that are accessed infrequently but must be retained for several years for compliance. Which two Azure storage options meet these requirements? (Select two.)
Question 3

The web tier VMs must be evenly distributed across two distinct data centers within an Azure region to avoid a single point of failure from an infrastructure outage. Which Azure construct should they use to meet this requirement?
Question 4
A company wants to enforce a set of security policies across all their Azure subscriptions. They have created several individual policy definitions. Which Azure construct should they use to group these policies together and assign them as a single package?
Question 5
A company deploys a line-of-business application on an Azure virtual machine. The IT team wants to ensure the application remains secure. According to the shared responsibility model, which of the following security tasks is the sole responsibility of the customer (the company)?
Question 6
A company develops a web API that runs on Azure App Service. The development team wants to deploy a new version of the API to a staging environment, run integration tests against it, and then gradually shift production traffic to the new version. If any issues are detected, they want to immediately roll back to the previous version without redeploying. Which Azure App Service feature should the team use to meet these requirements?
FAQ
Questions learners often ask
What does this AZ-900 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Azure Kubernetes Service (AKS) — Azure Kubernetes Service (AKS) is a managed Kubernetes service that handles the orchestration of containerized applications. It provides automatic scaling, service discovery, rolling updates, and abstracts the underlying VMs. Azure Container Instances (ACI) is for simple container deployment without orchestration. Azure App Service is for web apps, not native container orchestration. Azure Functions is serverless compute, not suited for multiple microservices with persistent state.
