| Front | Back |
| Compare Azure Storage Account types | Standard (general purpose v2) for most scenarios; Premium for high-performance workloads; Blob Storage (legacy) for block/append blobs only. |
| What are Azure Availability Zones? | Physically separate datacenters within an Azure region with independent power, cooling, and networking. |
| What are Azure managed disks? | Block-level storage volumes managed by Azure that eliminate the need to create and manage storage accounts. |
| What are the key benefits of Azure Virtual Machines? | Full control over OS and configuration; support for Windows and Linux; ideal for lift-and-shift migrations; pay-per-second billing. |
| What are the main benefits of Azure App Service? | Built-in auto-scaling and load balancing; support for multiple languages/frameworks; DevOps integration; high availability with SLA of 99.95%. |
| What are the three types of Azure Blob Storage? | Block blobs (general files); Append blobs (logging scenarios); Page blobs (frequent random read/write operations, VHD files). |
| What is a subnet in Azure networking? | A range of IP addresses within a VNet that helps organize and secure resources by group or function. |
| What is Azure Active Directory/Entra Id? | Microsoft's cloud-based identity and access management service that helps employees sign in and access resources. |
| What is Azure App Service? | A PaaS offering for hosting web apps, RESTful APIs, and mobile backends without managing infrastructure. |
| What is Azure Application Gateway? | A web traffic load balancer operating at Layer 7, with features like SSL termination, URL-based routing, and WAF capabilities. |
| What is Azure Blob Storage? | Object storage solution for unstructured data like images, videos, backups, and documents. |
| What is Azure Cache for Redis? | A fully managed in-memory data store based on Redis that improves performance of data-intensive applications. |
| What is Azure Container Instances (ACI)? | The fastest and simplest way to run containers in Azure without managing servers or higher-level services. |
| What is Azure Content Delivery Network (CDN)? | A distributed network of servers that delivers web content to users based on their geographic location. |
| What is Azure Cosmos DB? | A globally distributed, multi-model database service designed for high availability, elastic scaling, and low latency. |
| What is Azure Database for MySQL? | A fully managed MySQL database service for app development with built-in security and recovery. |
| What is Azure Database for PostgreSQL? | A fully managed PostgreSQL database service for app development with built-in security and recovery. |
| What is Azure Disk Storage? | Block-level storage volumes for Azure VMs available as Ultra Disks, Premium SSDs, Standard SSDs, and Standard HDDs. |
| What is Azure DNS? | A hosting service for DNS domains that provides name resolution using Microsoft Azure infrastructure. |
| What is Azure ExpressRoute? | A private dedicated connection between your on-premises network and Azure, bypassing the public internet. |
| What is Azure Files? | Fully managed file shares accessible via SMB or NFS protocols from cloud or on-premises. |
| What is Azure Functions? | A serverless compute service that runs code in response to events without provisioning or managing servers. |
| What is Azure Key Vault? | A service for securely storing and accessing secrets, keys, certificates, and other sensitive information. |
| What is Azure Kubernetes Service (AKS)? | A managed container orchestration service that makes it easier to deploy and manage containerized applications. |
| What is Azure Load Balancer? | A service that distributes incoming network traffic across multiple virtual machines for high availability and reliability. |
| What is Azure Monitor? | A comprehensive solution for collecting, analyzing, and responding to telemetry from cloud and on-premises environments. |
| What is Azure Policy? | A service that evaluates your resources for non-compliance with defined policies and can enforce rules for resources. |
| What is Azure Queue Storage? | Service for storing large numbers of messages that can be securely accessed from anywhere. |
| What is Azure RBAC (Role-Based Access Control)? | A system that provides fine-grained access management for Azure resources based on user roles. |
| What is Azure Security Center? | A unified security management and threat protection service across hybrid cloud workloads. |
| What is Azure SQL Database? | A fully managed relational database service based on Microsoft SQL Server with built-in intelligence and security. |
| What is Azure Table Storage? | NoSQL key-attribute datastore for schema-less storage of structured data. |
| What is Azure Traffic Manager? | A DNS-based traffic load balancer that distributes traffic across Azure regions for high availability and responsiveness. |
| What is Azure Virtual Machines? | An IaaS offering that allows you to deploy and manage VMs in Azure with full control over the OS and configuration. |
| What is Azure Virtual Network (VNet)? | An isolated network in Azure that allows resources to securely communicate with each other, the internet, and on-premises networks. |
| What is Azure VPN Gateway? | A service that connects on-premises networks to Azure through IPsec/IKE VPN tunnels. |
| What's the difference between Azure Storage redundancy options? | LRS (3 copies in 1 zone); ZRS (3 zones in 1 region); GRS (2 regions, async); RA-GRS (2 regions, async, read access); GZRS (combines ZRS+GRS). |
| When would you use Azure Functions instead of Azure App Service? | For event-driven architectures; microservices; tasks that run for limited time; when you want to pay only for execution time. |
