1Z0-1084-25 is a service-composition and delivery exam. Strong answers usually come from deciding whether the problem is API exposure, event handling, asynchronous processing, or safe retry behavior before picking the OCI service.
Idempotency: The property that lets a request or retry be processed safely without creating duplicate side effects.
Workflow orchestration: The coordination of multiple tasks, decisions, and failure paths across services.
What this guide emphasizes
OCI developer-facing services such as Functions, API Gateway, Events, and Streaming
CLI and service automation patterns that support repeatable delivery
retry, async flow, and connector-style integration logic
common exam traps around service boundaries and safe operation
What strong answers usually do
identify whether the issue is synchronous API exposure, async work delivery, or workflow coordination
separate transport, execution, and retry concerns instead of mixing them together
prefer answers that improve reliability and repeatability without adding unnecessary glue code
treat safe retry and event flow as design decisions, not afterthoughts
