System Architecture & Design Flashcards

What is the primary purpose of the IICS 'Serverless Runtime Environment'?

Answer: To run mappings on Informatica-managed cloud compute without provisioning or managing agents

The Serverless Runtime Environment lets IICS execute mappings on Informatica-managed infrastructure, eliminating the need to provision or maintain Secure Agents.

Which IICS design consideration is critical when integrating Salesforce using the standard Salesforce connector?

Answer: API governor limits in Salesforce must be factored into batch size and frequency design

Salesforce enforces daily API call limits (governor limits), so mappings must be designed with appropriate batch sizes and scheduling to avoid exceeding them.

In an IICS architecture with multiple Secure Agents in a group, how are tasks assigned to specific agents?

Answer: IICS load-balances tasks across available agents in the group automatically

IICS automatically distributes tasks across all active agents in a Secure Agent Group, providing load balancing without manual assignment.

Which transformation in IICS is used to flatten hierarchical (nested) data structures such as JSON arrays into relational rows?

Answer: Hierarchy Parser

The Hierarchy Parser transformation processes hierarchical input formats like JSON or XML and outputs flattened relational rows for downstream processing.

What is the recommended IICS architecture pattern for sharing common transformation logic (e.g., standardized address parsing) across multiple mappings?

Answer: Create a reusable Mapplet and reference it across mappings

A Mapplet encapsulates reusable transformation logic that can be embedded into multiple mappings, ensuring consistency and reducing maintenance overhead.

In IICS, which scheduler option allows a task to be triggered immediately upon the completion of another task or workflow?

Answer: Chained task execution within a Taskflow

Within a Taskflow, tasks can be chained so that one task starts automatically upon the successful (or failed) completion of a preceding task.

When designing IICS integrations that must comply with data residency regulations (e.g., GDPR), which architectural control is most relevant?

Answer: Selecting a Secure Agent and IICS pod region that keeps data within the required geography

Data residency compliance requires that both the IICS pod (cloud infrastructure region) and the Secure Agent processing data are located within the required geographic boundary.
