OGEA-101 Exam Dumps - TOGAF Enterprise Architecture Part 1 Exam (English)

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.

When scoping an architecture in TOGAF, three key axes (dimensions) are used to frame the extent of the architecture work. The first is time period (how far into the future or over what timeframe to plan). The second is depth—how detailed or granular the architecture models will be (e.g., high level, mid level, very detailed). The third is breadth, which refers to which parts (domains, business units, functions) of the enterprise will be included, and which architecture domains (business, data, application, technology) will be in scope. This triple‐dimension model helps architects, stakeholders, and governance bodies understand how wide, deep, and forward‑looking the architecture effort will be. Thus “breadth, architecture domains” is the correct third dimension.

According to the TOGAF Standard, 10th Edition, risk is present in all phases within the Architecture Development Method (ADM), and it should be identified, classified, and mitigated before starting a transformation effort 1. Risk is defined as “the effect of uncertainty on objectives” 2, and it can have positive or negative impacts on the architecture project. Risk management is a technique that helps to assess and address the potential risks that may affect the achievement of the architecture objectives, and to balance the trade-offs between opportunities and threats. Risk management is applied throughout the ADM cycle, from the Preliminary Phase to the Requirements Management Phase, and it is integrated with other techniques, such as stakeholder management, business transformation readiness assessment, gap analysis, and migration planning 1. The other options are not correct, as they are not present in all phases within the ADM, and they are not necessarily identified, classified, and mitigated before starting a transformation effort. Budgetary constraints are the limitations on the financial resources available for the architecture project, and they are usually considered in Phase E: Opportunities and Solutions, and Phase F: Migration Planning 3. Schedule constraints are the limitations on the time available for the architecture project, and they are also usually considered in Phase E and F 3. Information gaps are the missing or incomplete data or knowledge that may affect the architecture project, and they are usually identified in Phase B: Business Architecture, Phase C: Information Systems Architecture, and Phase D: Technology Architecture .
