Exam OGEA-101 Topic 2 Question 68 Discussion

Comprehensive and Detailed Explanation
Architecture Partitioning is an ADM technique in TOGAF that addresses how large and complex architectures can be broken down into manageable parts. The intent is to make architecture development more effective, especially in large enterprises with multiple teams, stakeholders, and domains.
Key points from TOGAF:
* TOGAF does not mandate a partitioning model. It provides guidelines and techniques to help architects determine whether and how to partition. This means statement 1 is incorrect.
* Statement 2: Correct. Architectures may be partitioned to allow different teams to work on different elements in parallel (e.g., by domain, line of business, geographic scope). Partitioning provides clear ownership and reduces overlap or conflict.
* Statement 3: Correct. Partitions can be structured in a way that supports architecture re-use, since well-defined partitions (e.g., capability-based or domain-based) enable consistent re-use of architecture building blocks across projects.
Correct Mapping
* Statement 1: Incorrect (partitioning is not required by ADM).
* Statement 2: Correct.
* Statement 3: Correct.
Correct answer is D (2 and 3).
Why the other options are incorrect
* A (1, 2 and 3): Incorrect because TOGAF does not require partitioning.
* B (1 and 3): Incorrect because 1 is not correct.
* C (1 and 2): Incorrect because 1 is not correct.
