Which of the following statements about architecture partitioning are correct*?
1 Partitions are used to simplify the management of the Enterprise Architecture
2 Partitions are equivalent to architecture levels
3 Partitions enable different teams to work on different element of the architecture at the same time.
4 Partitions reflect the organization's structure
- A. 1 & 4
- B. 2 & 4
- C. 2 & 3
- D. 1 & 3
正解：D
解説：
Statements 1 and 3 about architecture partitioning are correct. Architecture partitioning is the technique of dividing an architecture into smaller and more manageable parts that can be developed, maintained, and governed independently. Partitions are used to simplify the management of the Enterprise Architecture and to enable different teams to work on different elements of the architecture at the same time. Partitions are not equivalent to architecture levels, which are different degrees of abstraction or detail in an architecture. Partitions do not necessarily reflect the organization's structure, which may change over time or differ from the architecture's scope and boundaries.

質問 # 27
When considering the scope of an architecture, what dimension considers to what level of detail the architecting effort should go?
- A. Depth
- B. Architecture Domains
- C. Project
- D. Breadth
正解：A
解説：
The scope of an architecture is the extent and level of detail of the architecture work. The scope of an architecture can be defined along four dimensions: project, breadth, depth, and architecture domains. The project dimension considers the boundaries and objectives of the architecture project, such as the time frame, budget, resources, and deliverables. The breadth dimension considers the coverage and completeness of the architecture across the enterprise, such as the organizational units, business functions, processes, and locations. The depth dimension considers the level of detail and specificity of the architecture, such as the granularity, abstraction, and precision of the architectural elements and relationships. The architecture domains dimension considers the aspects or segments of the architecture, such as the business, data, application, and technology domains.
Therefore, the depth dimension is the one that considers to what level of detail the architecting effort should go.
