20+ practice questions focused on Describe Azure architecture and services — one of the most tested topics on the Microsoft Azure Fundamentals AZ-900 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Describe Azure architecture and services PracticeA development team wants to deploy a microservices-based application using containers. They want to orchestrate the containers with automatic scaling and rolling updates, but they want to avoid managing the underlying infrastructure such as virtual machines. Which Azure compute service meets these requirements?
Explanation: Azure Kubernetes Service (AKS) is the correct choice because it provides a managed Kubernetes orchestration platform that handles container deployment, automatic scaling, and rolling updates. To fully avoid managing virtual machine infrastructure, you can enable virtual nodes (backed by Azure Container Instances), which allow pods to run on serverless infrastructure without managing any VMs. This meets the team's requirement to avoid managing underlying infrastructure.
A company has a virtual machine running a legacy application that needs high-performance, low-latency storage for transactional data. They need to attach a storage solution that provides the highest IOPS and throughput. Which Azure managed disk type should they choose?
Explanation: Ultra Disk is the correct choice because it offers the highest IOPS and throughput of any Azure managed disk, with sub-millisecond latency, making it ideal for high-performance, low-latency transactional workloads. It supports up to 300,000 IOPS and 4,000 MB/s throughput per disk (depending on disk size), and allows independent scaling of IOPS and throughput without requiring a disk swap.
A company wants to migrate an on-premises application to Azure. The application requires consistently high disk throughput for database files. They plan to use Azure virtual machines with managed disks. Which disk type should they choose to get the highest possible IOPS and throughput at a premium cost?
Explanation: Ultra Disk (Option C) is correct because it provides the highest IOPS and throughput of any Azure managed disk type, with sub-millisecond latency, making it ideal for I/O-intensive workloads like database files. It is designed for premium cost scenarios where maximum performance is required, offering configurable IOPS and throughput independent of disk size.
A company needs to run a simple background job that runs every hour for 10 minutes. They want to containerize the job but do not want to manage a container orchestration platform. Which Azure service is simplest and most cost-effective?
Explanation: Azure Container Instances (ACI) is the simplest and most cost-effective choice because it allows you to run a containerized job directly without managing any underlying infrastructure or orchestration platform. For a short-lived hourly job that runs for only 10 minutes, ACI provides fast startup and per-second billing. To schedule the job to run every hour, combine ACI with a scheduler such as Azure Logic Apps or Azure Automation, but ACI itself is the container execution service. The `--restart-policy Never` flag ensures the container doesn't restart after it finishes, which is appropriate for a one-time job execution.
A company needs to share a set of files between multiple Azure VMs using the SMB protocol. They require a managed file share that can be mounted simultaneously by multiple VMs with permissions managed via Active Directory. Which Azure storage services should they use? (Select all that apply.)
Explanation: Azure Files provides fully managed SMB file shares that can be mounted concurrently by multiple Azure VMs and supports Active Directory authentication. However, Azure NetApp Files is also a managed file share service that supports SMB and NFS, can be mounted by multiple VMs, and supports Active Directory permissions. Therefore, both A and D satisfy the criteria as written. The question needs to be revised to differentiate between them (e.g., cost, performance, or service tier), or the correct answer set should include both.
