The TOGAF standard divides Enterprise Architecture into four primary architecture domains: business, data, application, and technology. These domains represent different aspects of an enterprise and how they relate to each other. The business domain defines the business strategy, governance, organization, and key business processes. The data domain describes the structure of the logical and physical data assets and data management resources. The application domain provides a blueprint for the individual applications to be deployed, their interactions, and their relationships to the core business processes. The technology domain describes the logical software and hardware capabilities that are required to support the deployment of business, data, and application services. Other domains, such as motivation, security, or governance, may span across these four primary domains. References:

TOGAF and the history of enterprise architecture | Enable Architect

Business principles business goals, and business drivers provide context for architecture work, by describing the needs and ways of working employed by the enterprise. They define what the enterprise wants to achieve, how it wants to operate, and what factors influence its decisions and actions.

Comprehensive and Detailed In-Depth Explanation from Expert in Enterprise Architecture, guiding in TOGAF and ArchiMate:

Architecture Partitioning is a technique supported by TOGAF to manage complexity and scale, especially in large enterprises.

Correct statements:

Statement 2 is correct: Partitioning enables parallel work by multiple teams on different parts of the architecture.

Statement 3 is correct: Partitioning supports architecture re-use by isolating common or shared components.

Why Statement 1 is incorrect:

TOGAF does not mandate a partitioning model. It supports and recommends partitioning where appropriate, but it is not a required element of the ADM.
