Discuss Isaca CDPSE Exam Topic 1 Question 79

An organization want to develop an application programming interface (API) to seamlessly exchange personal data with an application hosted by a third-party service provider. What should be the FIRST step when developing an application link?

AData tagging

BData normalization

CData mapping

DData hashing

Suggested Answer: C

Data mapping is the process of defining how data elements from different sources are related, transformed, and transferred to a common destination. Data mapping is the first step when developing an application link because it helps to ensure that the data exchanged between the API and the third-party application is consistent, accurate, and compatible. Data mapping also helps to identify any gaps, errors, or conflicts in the data and resolve them before the data transfer occurs.
