AZ-900 Microsoft Azure Fundamentals: Exam Prep in 5 Hours

Explore the three cloud models—public, private, and hybrid—and weigh their accessibility, security, control, and cost implications for your organization.

Identify use cases for public, private, and hybrid clouds by weighing budget, scalability, and compliance; apply public for unpredictable workloads and testing, private for security, and hybrid for balanced trade-offs.

Discover how high availability and scalability in cloud computing enable continuous operations by adapting resources on demand. Learn about service level agreements, downtime benchmarks, horizontal and vertical scaling, and elasticity.

Discover how reliability and predictability in the cloud build trust by ensuring resiliency and consistent performance, with autoscaling, load balancing, regions, and cost forecasting through the TCO calculator.

Describe how security and governance protect cloud assets, using Azure Policy and Defender for Cloud to enforce rules, monitor compliance, and improve the secure score.

Centralize Azure resource management with the Azure portal, Azure CLI, and infrastructure as code to automate tasks, monitor activity, and standardize deployments across your subscription.

Explore when to use IaaS, PaaS, and SaaS in Azure, weighing control and time to migrate, develop, and deploy with real-world scenarios like web development, analytics, and collaboration.

Describe how an Azure subscription acts as the logical unit linking user accounts to resources, bounding billing and access control under Microsoft contract, with free trial, pay-as-you-go, or enterprise agreement.

Describe how management groups provide scope above subscriptions to enforce policies, RBAC, and compliance across multiple subscriptions in Azure.

Explain how management groups, subscriptions, and resource groups organize resources from top to bottom with waterfall inheritance, policy application, and rbac with least privilege for secure access and clear billing.

Explore compute options—virtual machines, containers, and serverless functions—balancing control and management. Understand IaaS, container as a service, and function as a service distinctions with Azure offerings.

Compare Azure virtual machines, containers, and App Service to determine hosting options. IaaS offers full control, containers enable portability for microservices, and App Service delivers scalable HTTP-based web hosting.

Azure storage tiers, including hot, cool, cold, and archive, move data over time from hot to cool to cold to archive, balancing storage cost, access cost, and retrieval time.

Explain Azure storage redundancy options such as LRS, ZRS, GRS, and GZRS across primary and secondary regions to protect data, offer read access RA, and improve durability.

examine storage account options and types, including unique namespaces and urls, unified access to blobs, files, queues, tables, and disks, plus standard vs premium storage considerations.

Explore easy copy (azcopy), storage explorer, and file sync to move data between storage accounts, using command line bulk transfers or a graphical interface.

Discover how Azure external identities securely share apps and resources with partners and customers, using B2B collaboration, B2C authentication, and BYO identity federation.

Describe how Microsoft Entra conditional access uses signals from the user, location, device, and application to enforce policies by blocking, granting access, or requiring additional verification.

Master Azure RBAC to grant access on resources using Azure Resource Manager, enforce least privilege, separation of duties, and managed identities via access control IAM across subscriptions and resource groups.

Microsoft Defender for Cloud acts as a security advisor and active guard for your Azure subscription, identifies vulnerabilities and threats, shows a secure score, and offers recommendations to improve protection.

Understand how Azure costs come from resource specs, storage tiers, and region choices, then apply visibility, accountability, and optimization to optimize pay-as-you-go, reserved, and spot spending.

Describe how tags, as name-value metadata labels, organize Azure resources into a taxonomy and support cost management by revealing department, team, cost center, and environment details.
