1. Which IICS Secure Agent JVM tuning parameter should you increase when a mapping that processes large XML or JSON payloads throws 'OutOfMemoryError'? → -Xmx (maximum heap size)
2. Which IICS feature lets administrators enforce that all users must complete multi-factor authentication when logging in from outside the corporate network? → Conditional MFA policy based on network location
3. A developer wants to test an IICS connection that uses OAuth 2.0 without exposing the refresh token in task logs. What should they do? → Store the refresh token as a Secure Parameter and reference it in the connection
4. Which HTTP method should be used when designing an IICS API endpoint that creates a new resource on the server? → POST
5. What is a fundamental principle of DevOps & Deployment in Informatica Cloud Certification practice? → Following established standards and best practices
6. In IICS, what does the 'Incremental Load' pattern typically use to identify new or changed records? → A watermark column such as a timestamp or sequence ID
7. Which IICS feature enables field-level encryption so sensitive columns in a dataset are encrypted before being written to a target? → Data Masking transformation
8. In Informatica Cloud (IICS), which runtime environment executes mappings and tasks in a customer's private network? → Secure Agent
9. When integrating with a SOAP web service in IICS, which transformation is used to invoke the web service operation? → Web Service Consumer Transformation
10. When optimizing an IICS mapping that writes to Snowflake, which target load strategy generally provides the best bulk-insert performance? → Staging data in S3/Azure Blob and using Snowflake COPY INTO command
11. Which IDMC Taskflow feature helps QA teams ensure that a pipeline only proceeds to the next step when all prerequisite tasks succeed? → Success/Failure event-based sequencing
12. When using IICS to load data into Snowflake, which file staging approach typically yields the best bulk load performance? → Staging data in cloud storage (S3/Azure Blob) then using COPY INTO
13. In Informatica IICS, which feature allows a mapping to automatically restart from the last successfully committed row after a failure? → Fault tolerance with recovery
14. Which planning tool helps visualize project timelines in Informatica Cloud Certification? → Gantt chart
15. Which IICS Workflow best practice reduces the risk of long-running workflows consuming excessive Secure Agent memory? → Breaking large workflows into smaller chained or event-triggered sub-workflows
16. How does Informatica Cloud handle data security? → By encrypting data and implementing role-based access control
17. When configuring an IICS Taskflow, what is a Decision task used for? → To branch the flow based on a conditional expression evaluation
18. In IICS, which scheduler option allows a task to be triggered immediately upon the completion of another task or workflow? → Chained task execution within a Taskflow
19. Which cloud service model gives users the most control over the operating system and middleware? → IaaS
20. Which IICS transformation should be avoided in the critical path of a high-volume mapping because it blocks the pipeline until all input rows are received? → Aggregator transformation (without sorted input)
21. What is the purpose of a feasibility study in Informatica Cloud Certification project planning? → To determine if a project is viable and worth pursuing
22. In Informatica Cloud, when detecting duplicate records using a sorted input, which algorithm approach has the best time efficiency? → Sort then scan adjacent pairs in O(n log n)
23. Which IICS Data Integration transformation is best suited for parsing a nested JSON or XML hierarchy into relational rows? → Hierarchy Parser
24. What algorithmic technique does Informatica Cloud use when a joiner transformation processes two sorted inputs instead of caching one entirely in memory? → Merge (two-pointer merge of sorted arrays)
25. Which Informatica IICS feature allows you to promote objects from one organization to another without manual re-creation? → Data Integration export/import packages
26. During regression testing of an IDMC mapping after a schema change, which action should be performed first? → Refresh metadata on affected source and target objects
27. In IICS Workflow optimization, what is the main benefit of using concurrent task execution? → Reduces total elapsed time by running independent tasks simultaneously
28. Which IICS architecture layer is responsible for orchestrating multiple tasks, including decisions and loops, in a sequential or parallel flow? → Taskflow
29. In Informatica Cloud (IICS), which connection type is used to call an external REST API as a source or target in a mapping? → REST V2 Connection
30. When designing a mapping for Slowly Changing Dimension (SCD) Type 2 in IICS, which transformation pair is typically required? → Lookup and Update Strategy
