Consider the following statements:The TOGAF ADM requires a partitioning model for architecture development.

The correct answer is A .

Statement 1 is not correct as written. TOGAF 9.2 does discuss architecture partitioning and states that each enterprise needs to adopt a partitioning model that reflects its own operating model. However, TOGAF also states that it is impractical to present a definitive partitioning model for architecture. Therefore, the ADM does not impose one universal required partitioning model for all architecture development. Partitioning is an important technique, especially for large and complex enterprises, but the model must be tailored to the enterprise context.

Statement 2 is correct. TOGAF 9.2 explicitly states that architectures are partitioned when different teams need to work on different elements of architecture at the same time. Partitioning allows specific groups of architects to own and develop specific elements of the architecture. This supports parallel work, clearer ownership, and better governance.

Statement 3 is correct. TOGAF 9.2 states that effective architecture re-use requires modular architecture segments that can be taken and incorporated into broader architectures and solutions. Architecture partitioning therefore supports re-use by creating modular, manageable, and governable parts of the Architecture Landscape.

Therefore, only statements 2 and 3 are correct.
