OGEA-101 Exam Questions 2026 – Real Practice Test with Verified Answers

Explanation:
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.

Explanation:
The following activities are part of Risk Management:
Initial risk assessment
Risk mitigation and residual risk assessment
Risk monitoring
Risk Management is the process of identifying, assessing, and responding to risks that may affect the achievement of the enterprise’s objectives. Risk Management involves balancing positive and negative outcomes resulting from the realization of either opportunities or threats.

Explanation:
Gap Analysis is a technique that compares the Baseline Architecture and the Target Architecture to identify the differences and gaps between them. The purpose of this technique is to determine the changes and additions that are required to achieve the desired future state of the architecture. One of the main aspects of Gap Analysis is to identify the functions that are missing or overlapping in the current and future architectures, and to plan how to address them. This helps to ensure that the architecture is complete, consistent, and aligned with the business objectives and requirements3

Explanation:
The purpose of the Gap Analysis technique is similar to the previous question, but with a focus on the Target Architecture. The technique helps to identify the items that are not included or specified in the Target Architecture, such as capabilities, services, components, standards, or technologies. These items may be essential for achieving the vision and goals of the enterprise, or for addressing the stakeholder concerns and requirements. By identifying the items omitted from the Target Architecture, the technique helps to ensure that the architecture is comprehensive, feasible, and realistic.

Explanation:
The TOGAF standard covers the development of four architecture domains: Business, Data, Technology and Application. These domains represent different aspects of an enterprise’s architecture and provide a consistent way of describing, analyzing, and designing them.
