1Z0-1042-25 is an integration-and-reliability exam. Strong answers usually come from choosing the safest API, event, queue, and secret-handling pattern rather than just wiring services together.
Idempotency: A design property where retrying the same request does not create unwanted duplicate effects.
Connector pattern: A reusable integration path that moves or transforms data between services with a defined trigger and destination.
What this guide emphasizes
API exposure, auth, and policy boundaries
events, notifications, queues, and connector choices
functions, orchestration, and failure-handling patterns
observability, retries, secrets, and operational safety
What strong answers usually do
decide first whether the problem is synchronous API flow, asynchronous event flow, or background work
choose retry, backoff, and idempotency patterns deliberately
reduce public exposure and secret sprawl before adding more services
match the integration tool to the failure mode and operations burden, not just the happy path
