Sample IDMC for Databricks Foundation Practice Questions

Try these sample questions to test your IDMC for Databricks Foundation exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1What is the Databricks Lakehouse architecture?
A.A pure data warehouse with no support for unstructured data
B.A unified platform that combines data lake storage with data warehouse capabilities on a single source of truth
C.An on-premises mainframe replacement
D.A cache layer in front of a traditional Oracle database
Explanation: The Databricks Lakehouse unifies the openness and low cost of a data lake with the ACID transactions, governance, and performance of a data warehouse. Built on Delta Lake, it lets data engineering, BI, ML, and AI workloads run against a single source of truth rather than separate systems.
2Which open-source storage layer powers ACID transactions and time travel on the Databricks Lakehouse?
A.Apache Parquet
B.Delta Lake
C.Apache ORC
D.HDFS
Explanation: Delta Lake is the open-source storage layer that adds ACID transactions, scalable metadata, schema enforcement, and time-travel queries on top of Parquet files in cloud object storage. It is the native storage format of the Databricks Lakehouse.
3What is Unity Catalog in Databricks?
A.A scheduling service for Databricks jobs
B.A unified governance layer for data and AI assets across Databricks workspaces
C.A replacement for Delta Lake storage
D.A connector marketplace
Explanation: Unity Catalog is Databricks' unified governance solution for data and AI assets. It centralizes access control, auditing, lineage, and data discovery across workspaces with a three-level namespace of catalog.schema.table.
4What does IDMC stand for in the Informatica platform?
A.Integrated Data Management Cloud
B.Intelligent Data Management Cloud
C.Informatica Data Migration Console
D.Integrated Data Mart Cluster
Explanation: IDMC stands for Intelligent Data Management Cloud. It is Informatica's cloud-native, AI-powered platform for data integration, application integration, governance, quality, MDM, and ingestion, all powered by the CLAIRE AI engine.
5Which IDMC connector is used to read from and write to Databricks Delta tables?
A.Snowflake Data Cloud Connector
B.Databricks Connector (Databricks Delta)
C.Generic JDBC only
D.Oracle Connector
Explanation: The Databricks Connector (also referred to as the Databricks Delta connector) is the native IDMC connector for reading and writing Delta tables on Databricks SQL Warehouses or Databricks clusters. It supports both Cloud Data Integration and Mass Ingestion use cases.
6In an IDMC mapping, what does pushdown optimization (PDO) targeted at Databricks accomplish?
A.It compresses log files on the Secure Agent
B.It generates native Databricks SQL and pushes transformation logic into the Databricks SQL Warehouse for execution
C.It disables the Spark engine
D.It moves data through the Hosted Agent
Explanation: Pushdown optimization to Databricks converts mapping logic into native Spark SQL or ANSI SQL and runs it inside a Databricks SQL Warehouse or cluster. This minimizes data movement and uses Databricks compute for the heavy lifting.
7Which authentication method is commonly used by IDMC to connect to a Databricks workspace?
A.FTP credentials
B.Databricks Personal Access Token (PAT) or OAuth M2M
C.SMB share password
D.Telnet
Explanation: IDMC connects to Databricks using a Personal Access Token (PAT) or OAuth machine-to-machine (M2M) credentials, configured in the Databricks connection. OAuth M2M is recommended for production because tokens can be rotated centrally.
8What is Delta Live Tables (DLT) in Databricks?
A.A backup utility for Delta tables
B.A declarative framework for building reliable, maintainable, and testable data pipelines on the Lakehouse
C.A replacement for Unity Catalog
D.A monitoring dashboard
Explanation: Delta Live Tables (DLT) is a declarative ETL framework on Databricks that lets engineers define streaming and batch pipelines in SQL or Python, with built-in expectations, lineage, and orchestration. DLT manages dependencies and quality automatically.
9Which IDMC service designs and runs cloud ETL/ELT data pipelines that can land data in Databricks?
A.Cloud Application Integration (CAI)
B.Cloud Data Integration (CDI)
C.Cloud Data Quality (CDQ)
D.Operational Insights
Explanation: Cloud Data Integration (CDI) is the IDMC service that designs and runs batch and ELT pipelines using the Mapping Designer. CDI mappings can read sources and write to Databricks Delta tables using the Databricks connector.
10What is the role of the IDMC Secure Agent when integrating with Databricks?
A.It hosts the Databricks workspace itself
B.It acts as the runtime that executes mappings and connects securely to Databricks endpoints
C.It replaces Unity Catalog
D.It is only used for on-prem Oracle sources
Explanation: The Secure Agent is a lightweight runtime that executes IDMC tasks and manages secure outbound connections to Databricks workspaces and SQL Warehouses. Even when work is pushed down to Databricks, the Secure Agent orchestrates the job and handles credentials.
