• and Power Platform CLI (`pac` and `pa`) if you want to test code patterns hands-on alongside explanations

Description

Scaffolding a quick model-driven form script or basic Dataverse table takes minutes. Explaining why an unmanaged hotfix layer in UAT silently masks every new Managed deployment beneath it, why caching IOrganizationService as a class field on a C# IPlugin causes cross-user data leaks under concurrent saves, why Power Apps code apps (`pa app`) drop Application Insights beacons until `connect-src` overrides `connect-src ‘none’` and reject shared SQL logins, why Power Platform Managed Identity v2 binds a certificate-signed `.nupkg` to Entra Federated Identity Credentials with zero client secrets, or how a custom Microsoft Foundry agent consumes Dataverse’s `/api/mcp` server with Work IQ domain skills and `@microsoft/agents-copilotstudio-client` consent cards is what Exam PL-400 (and its identical-blueprint successor Exam AB-400) actually tests.
