Azure Fundamentals: AZ-900 Certification +Practice Questions

Explore cloud concepts and the benefits of moving to the cloud, compare public, private, and hybrid models, differentiate IaaS, PaaS, and SaaS, and examine cost management and administration.

Track monthly updates to the Azure portal and Microsoft 365 portal, noting minor changes like renamed options or moved tabs, while the course is updated quarterly to reflect evolving interface.

Learn the difference between CapEx and OpEx, contrasting hardware upfront costs and tax deductions with pay-as-you-go cloud services that replace physical infrastructure.

The private cloud is a single-company owned, access-restricted environment secured by a site-to-site vpn. The company owns hardware and licensing and relies on a smee for cloud security.

Understand how a hybrid cloud combines public and private clouds, where a public web server connects to a private database, enabling secure, publicly accessible applications for sensitive data.

Explore the different types of cloud services—infrastructure as a service, platform as a service, and software as a service—and define their characteristics.

Explore core Azure services and architectural components, learn how regions and geographies affect data storage, and review Azure product offerings, solutions, and management tools for public and hybrid clouds.

Explore how Azure resource groups organize resources for an application as a manageable unit. Set up metering, billing, quotas, policies, and access controls while understanding deletion effects.

Explore Azure compute and virtual machines, including on-demand provisioning, disks, memory, networking, and containers, with emphasis on VM scale sets, App Services, and Functions.

Configure a Windows VM as a web server by installing the IIS role, verify access via the public IP, then stop and restart the VM in the Azure portal.

Explore how Azure dedicated hosts place your virtual machines on dedicated physical servers, with host groups, regions, availability zones, and fault domains to achieve high availability.

Demonstrates installing the Azure PowerShell module, authenticating to an Azure subscription, and using tab completion to create, manage, and delete resource groups with get-help.

Explore Azure network services, including the Azure virtual network for VM-to-VM communication and on-premises connections, plus VPN gateway, load balancer, application gateway, and CDN across regions.

Explore Azure virtual networks, where an address space defines subnets and network IDs, and where computers can communicate only when they share the same virtual network.

ExpressRoute offers private, high-speed connectivity between your on premise network and Azure resources via a site-to-site link, encrypted and provider-dependent, with configurable bandwidth in the Azure portal.

Demo shows configuring Azure blob storage by creating a storage account and container, uploading data, and mapping a Z drive with a PowerShell script.

Explore Azure database services, including Cosmos DB for globally distributed data with user updates, and a managed Azure SQL Database, plus a migration tool for on prem to Azure migrations.

Explore the Azure marketplace to search, trial for 30 days, purchase, and provision thousands of applications in your Azure environment, with categories like artificial intelligence, machine learning, and blockchain compute.

Azure arm templates let you reuse settings to quickly deploy Windows virtual machines and related resources. Visualize, edit, and reuse templates to reduce administrative errors.

Apply Azure locks to protect resources from accidental modification or deletion, using read-only and delete locks, which can be applied and removed in the portal.

Watch a Windows 11 autopilot demo that gathers hardware information using PowerShell, installs the get-windows-autopilot-info script, and exports a hwid.csv to the desktop.

Import Windows autopilot devices from a CSV into Intune, create a deployment profile, and assign devices to an Azure AD joined, user-driven autopilot group.

Sign in with a Microsoft account confirms autopilot device is assigned, configured, and connected to Azure AD, with serial-number naming and possible multi-factor authentication or pin requirements.

Azure Virtual Desktop (AVD) provides secure remote access across devices, delivering applications and desktops on demand while centralizing updates and administration for scalable, cost-efficient resource use.
