Microsoft AZ-104: Azure RBAC Roles and Scope
Home/Certifications/Microsoft/Microsoft AZ-104: Azure RBAC Roles and ScopeCloud & ArchitectureUpdated October 10, 2026 · 7 min readAzure role-based access control does not grant permission through a role name alone. Every effective assignment combines a security principal, a role definition and a scope, then interacts with inherited assignments and other control boundaries. Designing least privilege requires deciding who needs access, what actions they need, and where those actions should be allowed. A role assignment that works at one resource group may unintentionally broaden access when applied at the subscription. Compare the intended…
Microsoft AZ-104: Resource Groups in Practice
Home/Certifications/Microsoft/Microsoft AZ-104: Resource Groups in Practice Cloud & ArchitectureUpdated October 10, 2026 · 11 min read Azure resource groups are more than folders in a portal. Their boundaries shape what teams can change, what can be retired safely, where policy and permissions apply, and how deployment history can be explained after something breaks. On this pageChoose boundaries by the work that changes togetherKeep location and networking separate from group membershipDesign access around operators rather than organizational labelsPolicy and locks need a useful scope, not the widest scopeTreat deployment history as…
Microsoft AZ-104: Troubleshoot VNets, Routes, and DNS
Home/Certifications/Microsoft/Microsoft AZ-104: Troubleshoot VNets, Routes, and DNSCloud & ArchitectureUpdated October 10, 2026 · 7 min readAn Azure network connection can fail even when the virtual machines are healthy and the network security groups appear permissive. A wrong destination address, an unintended next hop or an incorrect DNS answer can produce similar symptoms. Troubleshooting is faster when you prove each part of the path separately rather than changing routes, peering and security rules at once. One wrong DNS answer can send a healthy application toward a destination that no route or…
Microsoft AZ-104: Azure Private Endpoints and DNS
Home/Certifications/Microsoft/Microsoft AZ-104: Azure Private Endpoints and DNS Cloud & ArchitectureUpdated October 10, 2026 · 7 min read A private endpoint gives an Azure service a private network entry point, but successful application access still depends on correct DNS, routing, service permissions, and a clear separation between public and private paths. A private endpoint changes the name-to-address path as well as the traffic route. If the application resolves a public address or the wrong private zone, a restrictive network design may be technically correct while the connection still fails. On this…
Microsoft AZ-104: Azure Storage Account Decisions
Home/Certifications/Microsoft/Microsoft AZ-104: Azure Storage Account Decisions Cloud & ArchitectureUpdated October 10, 2026 · 9 min read The difficult storage decisions happen before the first blob is uploaded: failure-domain coverage, network paths, identity-based access, account capabilities, data lifecycle, and an owner who can explain each choice. A storage configuration that is convenient during development can become expensive or risky when access patterns, redundancy needs, and retention change. Make each account choice traceable to a workload requirement, including the identity permitted to read the data. On this pageBegin with the data’s actual…
