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 company is planning to migrate its on-premises applications to Azure. They have a mix of monolithic and microservices-based applications. Which Azure compute service should they choose for a microservices architecture that requires independent scaling and deployment of components?
Explanation: Azure Kubernetes Service (AKS) is the correct choice because it provides a managed Kubernetes orchestration platform designed specifically for microservices architectures. AKS enables independent scaling, deployment, and management of containerized components, which aligns with the requirement for decoupled services that can be updated or scaled individually without affecting the entire application.
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.)
Explanation: Blob Storage Cool tier is correct because it is designed for data that is accessed infrequently but needs to be stored for at least 30 days, offering lower storage costs than the Hot tier while maintaining low-latency access. Blob Storage Archive tier is correct because it is the lowest-cost storage option for data that is rarely accessed and has a flexible retrieval time (hours), making it ideal for long-term compliance retention of video files.
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?
Explanation: Option B is correct because Azure Functions in the Premium plan supports VNet integration, allowing the function to securely access resources in a connected on-premises network via a site-to-site VPN without exposing the database to the public internet. The Consumption plan lacks VNet integration, and Azure SQL Database is a PaaS service, not a compute service for running serverless code.
A company is designing a multi-tier application on Azure. The web tier needs to scale out based on CPU usage, while the database tier requires high-performance storage for transactional data. Which combination of Azure services should they choose?
Explanation: Azure App Service provides built-in autoscaling based on metrics like CPU usage, making it ideal for the web tier that needs to scale out. Azure SQL Database offers high-performance, low-latency storage for transactional data with features like automatic indexing and in-memory OLTP, meeting the database tier's requirements.
A company is deploying a mission-critical application that must remain available even if a physical Azure datacenter within a region fails. The application will run on multiple virtual machines. Which Azure feature should they use to protect against this specific failure scenario?
Explanation: Availability Zones are physically separate datacenters within an Azure region, each with independent power, cooling, and networking. By deploying VMs across multiple zones, the application remains available even if one entire datacenter fails. This directly addresses the requirement for protection against a physical datacenter failure within a region.
