The Open Group OGEA-101: TOGAF Enterprise Architecture Part 1 (Foundation)

Last checked November 10, 2026 against the official The Open Group exam page.

1. Question 1Concepts of Enterprise Architecture and the TOGAF Standard

   A newly appointed head of architecture at a retail group wants one repeatable method that every business unit's architects follow, so their outputs can be compared. Which TOGAF component should she adopt as the core process?

   1. AA catalog of Solution Building Blocks for each product line
   2. BThe Architecture Development Method (ADM)
   3. CA taxonomy of reusable assets in the Architecture Continuum
   4. DA stakeholder map showing power and interest for each business unit
   Show answer and explanationHide answer

   Correct answer: B

   The Architecture Development Method is the repeatable process TOGAF provides for developing architectures, so it meets the need for one shared method. Solution Building Blocks are implementation components, the Architecture Continuum classifies reusable assets, and a stakeholder map is an engagement technique rather than a process for building architecture.

2. Question 2Key terminology of the TOGAF Standard

   Which description matches the TOGAF term 'deliverable'?

   1. AA work product such as a diagram, catalog or matrix produced during architecture work
   2. BA reusable component that delivers a defined functionality within a solution
   3. CA formal output that is agreed with stakeholders and is contractually defined
   4. DA group of people or organizations that has an interest in the architecture
   Show answer and explanationHide answer

   Correct answer: C

   In TOGAF, a deliverable is a formal, contractually agreed output of an architecture project that is reviewed and signed off. The first option describes an artifact, the second a building block, and the third a stakeholder, so none of them is the deliverable.

3. Question 3Architecture Development Method (ADM) cycle

   Which ADM phase establishes the architecture capability, such as principles, framework tailoring and governance arrangements, before any specific architecture project begins?

   1. APhase A, which validates the business context, defines the scope and produces the Architecture Vision and statement of work
   2. BThe Preliminary Phase, which establishes the architecture capability, principles and framework
   3. CPhase G, which governs implementation against the target architecture
   4. DPhase H, which manages changes to the architecture after deployment
   Show answer and explanationHide answer

   Correct answer: B

   The Preliminary Phase prepares the organization by establishing the architecture capability, including frameworks, principles and governance arrangements. Phase A starts a specific architecture project, Phase G governs implementation, and Phase H handles change, so none of those prepares the capability.

4. Question 4Techniques supporting the ADM

   Which technique compares the baseline architecture with the target architecture to identify what is missing, mismatched or needs to change?

   1. ABusiness scenarios, which capture actors, goals and processes to derive requirements
   2. BArchitecture patterns, which record reusable solutions to recurring problems
   3. CGap analysis, comparing baseline and target architectures
   4. DStakeholder management, which identifies and engages people who have concerns
   Show answer and explanationHide answer

   Correct answer: C

   Gap analysis is a TOGAF technique that compares the baseline architecture with the target architecture to identify gaps. The other techniques support requirements capture, reusable solutions and stakeholder engagement rather than comparing architecture states.

5. Question 5Applying the ADM

   A bank's architecture team has finished its information systems work for a retail division. New regulation then arrives, so the team loops back to revisit its business architecture before continuing. What is this return to an earlier stage called in the ADM?

   1. APartitioning of the architecture into smaller, independent segments
   2. BA formal compliance review carried out by the Architecture Board
   3. CAn iteration of part of the ADM cycle, revisiting an earlier phase
   4. DArchitecture change management under Phase H of the cycle
   Show answer and explanationHide answer

   Correct answer: C

   Iteration means revisiting earlier parts of the ADM when new requirements or conditions arise, so looping back to Phase B is an iteration. Partitioning divides the architecture work, Phase H covers changes after deployment, and a compliance review is a governance activity, so none of the other options describes revisiting an earlier phase.
