Informatica CAI R42 Professional study plan

Map the CAI service architecture end to end by sketching how a published process is exposed, invoked, and monitored, then labeling each component

Define the core building blocks (process, service, service connector, guide, app connection, event) in your own words and record where each one is configured in the user interface

Create a free Informatica organization or trial environment and confirm you can open the Process Designer and the Service Connector catalog

List the connection types available in your environment and group them by protocol family (REST, SOAP, database, file, messaging)

Build a process that accepts an input parameter, transforms it with an assignment step, and returns a response to a synchronous caller

Add conditional branching and a loop over a collection, and verify behavior by running the process in debug mode with sample payloads

Configure error handling with a fault path or scope so a failing step produces a controlled error response instead of an unhandled exception

Document how process variables differ from parameters and when each should be used

Create app connections for at least two different connector types and validate each with a test operation

Invoke a REST endpoint from a process, map the JSON response into process variables, and handle a non-200 status code explicitly

Consume a SOAP operation and explain how the WSDL drives the generated request structure

Compare connection-level authentication options (basic, OAuth, token-based) and pick the right one for a given scenario

Design a process that reacts to an event or message rather than a direct call, and explain the difference in invocation and lifetime

Add a human task or approval step and describe how the guide surfaces it to an end user

Publish a process as a service and invoke it from an external client such as a REST tool

Review the monitoring view to locate run history, step-level status, and error details for a failed execution

Implement retry and timeout behavior around an unreliable external call and prove the retry path executes

Add logging and audit steps so each run records key input, output, and decision values

Design a process that reads from a database and writes to a file or message target, handling empty result sets

Explain how process versions and redeployment affect running instances

Build a small integration that chains three services with data transformation between each hop

Apply mapping and expression functions to reshape a nested payload into a flat target structure

Test the chained integration with malformed and partial data to confirm defensive handling

Identify where secrets and credentials should live and how they are referenced from a connection

Review the full domain outline and list every objective you cannot yet explain without notes

Re-implement, from a blank process, the two designs you found hardest in weeks 2 through 6

Write a troubleshooting checklist covering connection failures, mapping errors, and runtime exceptions

Time yourself on scenario-style questions and record which themes produce the most wrong answers

Close every remaining open item on the week 7 gap list

Explain aloud, without notes, the end-to-end lifecycle of a CAI process from design to monitoring

Run a full timed practice set and review every missed item to root cause

Consolidate your glossary, diagrams, and checklists into a single review document for the final days
