Question 1

Which data integration pattern is most appropriate for synchronizing large volumes of data between enterprise systems on a scheduled basis?

Accepted Answer

Batch ETL (Extract, Transform, Load) processing

Answer

Batch ETL is designed to extract, transform, and load large volumes of data at scheduled intervals, making it well-suited for high-volume, time-insensitive data synchronization workloads.

Question 2

What is the key architectural difference between a data lake and a data warehouse?

Accepted Answer

A data lake stores raw data in native format while a data warehouse stores processed, structured data

Answer

A data lake stores raw data in native format (structured, semi-structured, unstructured) using schema-on-read, while a data warehouse uses schema-on-write with processed, integrated, structured data.

Question 3

What does the CAP theorem state about distributed data systems?

Accepted Answer

A distributed system cannot simultaneously guarantee Consistency, Availability, and Partition tolerance

Answer

The CAP theorem states that a distributed data system can only guarantee two of three properties simultaneously: Consistency, Availability, and Partition tolerance.

Question 4

What is the primary advantage of a data mesh architecture approach?

Accepted Answer

Enabling domain teams to own, manage, and serve their data as products

Answer

Data mesh decentralizes data ownership to domain teams who treat data as products, improving scalability, agility, and the application of domain expertise to data quality and management.

Question 5

Which integration approach best supports real-time data flow between microservices with loose coupling?

Accepted Answer

Event streaming using a message broker such as Apache Kafka

Answer

Event streaming with message brokers like Apache Kafka enables real-time, decoupled data integration through publish-subscribe patterns, ensuring services remain independent and scalable.
