CDP Data Integration and Interoperability 3

Question 1

What role does metadata play in supporting data integration processes?

Accepted Answer

It describes the structure, origin, lineage, and transformation history of integrated data

Answer

Metadata provides context about integrated data — including its structure, source systems, transformation rules applied, and lineage — enabling teams to understand, govern, and troubleshoot integrations.

Question 2

In Service-Oriented Architecture (SOA), which principle is most critical for achieving system interoperability?

Accepted Answer

Services expose standard, language-agnostic interfaces that any compliant consumer can invoke

Answer

SOA achieves interoperability by requiring services to use standard, technology-neutral interfaces (such as WSDL/SOAP or REST), allowing any system to consume them regardless of underlying implementation.

Question 3

What is the purpose of a staging area in a data integration architecture?

Accepted Answer

To provide a temporary zone where data is validated, cleansed, and transformed before loading to the target

Answer

A staging area is a transient workspace that holds data extracted from source systems while it undergoes validation, cleansing, and transformation before being loaded into the final target.

Question 4

Which lightweight, human-readable data interchange format has become widely dominant for REST API data exchange?

Accepted Answer

JSON (JavaScript Object Notation)

Answer

JSON has become the dominant format for REST API data exchange due to its lightweight structure, human readability, and native compatibility with modern programming languages.

Question 5

What is the key distinction between synchronous and asynchronous data integration?

Accepted Answer

In synchronous integration the sender waits for a response before proceeding; in asynchronous the sender continues without waiting

Answer

Synchronous integration requires the calling system to wait for a response before proceeding, while asynchronous integration allows the sender to continue processing after sending a message, receiving any response later.
