Exam CISA topic 1 question 1355 discussion

A. Application architecture Data flow, interfaces and relationships are all part of the application architecture.

In this scenario, when an IS auditor is tasked with reviewing an organization's technology relationships, interfaces, and data, the most appropriate enterprise architecture (EA) area for this review would be the Reference Architecture (option C). Reference architecture provides a standardized way of representing and organizing an organization's technology landscape, including its relationships, interfaces, and data flows. It serves as a blueprint or guideline for designing and implementing technology solutions within the organization. Therefore, reviewing the reference architecture would provide the IS auditor with insights into how technology components interact, exchange data, and interface with each other within the organization's IT environment.

D is indeed relevant, it primarily addresses the security aspects of the organization's technology relationships, interfaces, and data. However, the question seems to emphasize a broader scope, including not only security but also the overall structure, interactions, and flows of technology within the organization.
