E. Data Architecture
Answer
A. Technology Architecture
C. Application Architecture
D. Business Architecture
E. Data Architecture
Explanation
According to the Oracle Cloud Infrastructure (OCI) Cloud Adoption Framework and standard Enterprise Architecture (EA) practice, Enterprise Architecture is typically composed of four main domains:
- D. Business Architecture – defines the organization’s strategy, capabilities, processes, and governance that the cloud must support.
- E. Data Architecture – describes how data is collected, stored, governed, and used across the organization.
- C. Application Architecture – specifies how applications are structured, integrated, and aligned with business processes.
- A. Technology Architecture – covers the underlying infrastructure, such as networks, compute, storage, and platform services, that hosts the applications and data.
While Process Architecture (B) is sometimes discussed in broader EA or process‑management contexts, OCI CAF and most mainstream EA references group process concerns within Business Architecture rather than as a separate, core EA component.
