1What does the IDMC platform stand for in Informatica's product naming?
A.Informatica Data Migration Cloud
B.Intelligent Data Management Cloud
C.Integrated Data Mart Cluster
D.Informatica Distributed Mapping Console
Explanation: IDMC stands for Intelligent Data Management Cloud. It is Informatica's unified, AI-powered, cloud-native platform that hosts services such as Cloud Data Integration, Cloud Mass Ingestion, Cloud Data Quality, and Cloud Data Governance and Catalog, all powered by the CLAIRE AI engine.
2Which IDMC service is most commonly used by data engineers to design batch and ELT data pipelines?
A.Cloud Application Integration (CAI)
B.Cloud Data Integration (CDI)
C.Cloud Data Quality (CDQ)
D.Cloud Data Governance and Catalog (CDGC)
Explanation: Cloud Data Integration (CDI) is the IDMC service for designing and executing batch and ELT data pipelines using the Mapping Designer. CAI focuses on real-time API and process integration, CDQ enforces data quality rules, and CDGC handles governance and lineage.
3What is the primary purpose of the Cloud Mass Ingestion (CMI) service in IDMC?
A.Designing complex transformation logic with the Mapping Designer
B.Bulk and continuous ingestion of databases, files, applications, and streaming sources into cloud targets
C.Profiling and scoring data quality on landed datasets
D.Defining business glossary terms and certified data assets
Explanation: Cloud Mass Ingestion is purpose-built to move large volumes of data into cloud targets quickly. It supports four ingestion subtypes — Database, File, Application, and Streaming — with wizard-driven configuration and built-in change data capture for databases.
4Which difference best distinguishes ETL from ELT in cloud data engineering?
A.ETL transforms data before loading the target; ELT loads first and transforms inside the target
B.ELT only works with relational sources, while ETL works with any source
C.ETL always uses Spark, while ELT always uses SQL
D.ELT requires a Secure Agent, while ETL does not
Explanation: In ETL the transformation happens in a dedicated engine before the target is loaded. In ELT the raw data is loaded first and transformations are pushed down as SQL inside a cloud warehouse such as Snowflake, BigQuery, or Databricks SQL, leveraging the warehouse's compute.
5In the medallion lakehouse architecture, what does the bronze layer typically contain?
A.Final business-ready aggregated marts
B.Cleansed and conformed dimensional data
C.Raw ingested data, kept as close to the source as possible
D.Machine learning feature stores only
Explanation: The medallion architecture organizes a lakehouse into bronze, silver, and gold layers. Bronze stores raw, append-only data as it lands from sources, silver stores cleansed and conformed data, and gold stores business-ready aggregates for analytics and ML.
6Which open table format was originally created by Databricks and is widely used for ACID transactions on cloud object storage?
A.Apache Iceberg
B.Apache Hudi
C.Delta Lake
D.Apache ORC
Explanation: Delta Lake is the open table format originally created by Databricks that adds ACID transactions, schema enforcement, and time travel on top of Parquet files in cloud object storage. Iceberg and Hudi are alternative open table formats with similar goals.
7What does the CLAIRE AI engine do across IDMC services?
A.Replaces the Secure Agent for runtime execution
B.Provides metadata-driven recommendations, classifications, and automation
C.Acts as the only supported data quality scoring engine
D.Stores all customer data inside the Informatica cloud
Explanation: CLAIRE is Informatica's metadata-driven AI engine. It powers recommendations, automated classification, mapping suggestions, optimal pushdown mode selection, and natural-language data management through CLAIRE GPT across the entire IDMC platform.
8Which runtime is required to connect IDMC to on-premises databases or files behind a corporate firewall?
A.Hosted Agent
B.Serverless runtime
C.Secure Agent
D.Spark cluster runtime
Explanation: The Secure Agent is the IDMC runtime installed on a customer-controlled VM, container, or on-prem server. It establishes outbound connections to IDMC, allowing it to access on-premises sources and targets without inbound firewall holes.
9Which file format is the default underlying storage layout for a Delta Lake table?
A.Avro
B.Parquet
C.CSV
D.JSON
Explanation: Delta Lake stores its data as Parquet files in object storage and adds a transaction log (the _delta_log directory) to provide ACID semantics and time travel. Avro, CSV, and JSON are not the underlying storage layout for Delta tables.
10In a CDI mapping, which transformation is best suited to combine rows from two heterogeneous sources on a join condition?
A.Aggregator
B.Joiner
C.Router
D.Sequence Generator
Explanation: The Joiner transformation combines rows from two pipelines on a user-defined join condition, supporting normal, master outer, detail outer, and full outer joins. It is required when the two sources cannot be joined directly in the source query.
