When problems are reported
When external audits are scheduled

Correct answer: Regularly at defined intervals with additional reviews triggered by significant events

Regular scheduled reviews ensure ongoing monitoring while event-triggered reviews capture the impact of significant changes.

Question 2: Which component of PowerCenter manages the execution of workflows and sessions?

Repository Service.
PowerCenter Client.
Integration Service (Correct answer)
Workflow Manager.

Correct answer: Integration Service

The Informatica PowerCenter Integration Service is the core execution engine responsible for running workflows and sessions. It connects to source and target systems, extracts data, applies the transformation logic defined in mappings, and loads the processed data. Essentially, it performs the actual data integration and ETL tasks as orchestrated by the workflow.

Question 3: Which of the following is a common cause of session failures?
