Microsoft describes the Azure Administrator as someone who implements, manages, and monitors an organization's Azure environment. That is broader than memorizing portal locations. A useful lab should force you to make identity, network, storage, compute, governance, and monitoring decisions and then troubleshoot the consequences.
Manage identities and governance
Practice Microsoft Entra users and groups, role-based access control, subscriptions, resource groups, Azure Policy, tags, locks, and cost/governance boundaries. Be able to explain the difference between directory identity, Azure RBAC authorization, resource ownership, and policy compliance.
Implement and manage storage
Work with storage accounts, redundancy choices, access control, shared access patterns, lifecycle rules, file services, object storage, encryption, private endpoints, and network restrictions. Know what belongs in identity policy versus a storage configuration.
Deploy and manage compute
Build and operate virtual machines, availability patterns, scale sets, containers where applicable, and application-hosting options. Practice images, disks, extensions, backup, sizing, identity, networking, and the operational effect of changing a resource after deployment.
Virtual networking and monitoring
Practice VNets, subnets, routing, NSGs, DNS, peering, load-balancing concepts, private connectivity, Network Watcher, Azure Monitor, alerts, Log Analytics, and recovery signals. Troubleshooting is where separate objectives become one administrator workflow.
