The Open Group Updated OGEA-101 Exam Questions and Answers by helena

Architecture partitioning is not the same as architecture levels (so 1 is incorrect).

It allows different teams of architects to work on different parts of the architecture in parallel (2 is correct).

TOGAF does not prescribe a fixed partitioning model; it provides guidance (so 3 is incorrect).

Partitioning is used to simplify management of Enterprise Architecture in large or complex organizations (4 is correct).

Within the TOGAF Architecture Repository, the Architecture Capability component contains the organizational and governance support needed to operate the repository and the architecture function effectively. This includes the parameters, structures, roles, processes, and control mechanisms that allow the repository and architecture practice to be governed in a disciplined way. Because of that, option D is the correct match.

The other descriptions relate to different repository components. “The architectural representation of assets in use or planned” belongs more closely to the Landscape Repository, which captures current and planned architecture assets. “The standards with which new architectures must comply” corresponds to the Standards Information Base, where relevant standards and rules are maintained. “A record of governance activity across the enterprise” aligns with the Governance Log, which tracks governance-related actions and decisions. “Authorized change requests from the Architecture Board” would be treated as governance-controlled change information rather than the Architecture Capability itself.

TOGAF distinguishes the Architecture Capability from the content held in the repository because capability is about how architecture is governed and supported, not only what architecture content is stored. Therefore, the correct answer is the parameters, structures, and processes to support governance of the Repository, which is option D.

===========

 According to the TOGAF template for Architecture Principles, the Rationale section should describe the relationship to other principles, as well as the business benefits and the intentions of adhering to the principle. The Rationale section should use business terminology and point to the similarity of information and technology principles to the principles governing business operations. The Rationale section should also explain how the principle supports the achievement of the business objectives and key architecture drivers. References:

The Open Group Exam OGEA-103 Topic 1 Question 4 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.
