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

   A procurement lead at a logistics company asks why the enterprise architecture team should use the TOGAF Standard instead of inventing its own method. Which description of the TOGAF Standard is most accurate?

   1. AA proprietary software product that automatically generates an enterprise architecture repository from existing system inventories
   2. BAn open, vendor-neutral framework and method for enterprise architecture that gives a common vocabulary and a repeatable approach
   3. CA legal regulation that requires every organization to publish its complete IT systems inventory to a government registry each year
   4. DA mandatory technology platform that every vendor product must be certified on before any architecture work can begin
   Show answer and explanationHide answer

   Correct answer: B

   The TOGAF Standard is an open, vendor-neutral framework and method that organizations can tailor. Option A describes a tool rather than the standard, option C describes a legal obligation the standard does not impose, and option D invents a platform requirement that does not exist.

2. Question 2Key terminology of the TOGAF Standard

   During an architecture engagement, the regional sales director asks for faster quote turnaround, while the finance team asks that every change keeps a complete audit trail. The architect records both requests so the architecture can address them. In TOGAF terminology, what are these requests?

   1. AArchitecture principles, which set the general rules for how the enterprise uses its resources over time
   2. BConcerns, which are the interests of stakeholders that the architecture must address
   3. CBusiness capabilities, which are the abilities the enterprise needs in order to achieve its purpose
   4. DBuilding blocks, which are the reusable components that the solution will be assembled from
   Show answer and explanationHide answer

   Correct answer: B

   TOGAF defines a concern as an interest in the system held by a stakeholder, and both requests come from stakeholders, so they are concerns. Principles, building blocks, and capabilities are different architecture terms that describe rules, components, and abilities.

3. Question 3Introduction to the ADM cycle

   A team has been asked to define the target business processes, capabilities, and organization for a new operating model, before any applications or infrastructure are selected. Which ADM phase does this work belong to?

   1. APhase B, Business Architecture, which covers business strategy, organization, functions, and processes
   2. BPhase D, Technology Architecture, which covers the platforms that will host the solution
   3. CPhase E, Opportunities and Solutions, which identifies and evaluates the implementation projects
   4. DPhase C, Information Systems Architectures, which covers the data and application design needed to support the new operating model
   Show answer and explanationHide answer

   Correct answer: A

   Business Architecture (Phase B) describes business strategy, organization, functions, and processes, so it comes before the information systems and technology work. Phases C and D come after it, and Phase E turns the architectures into implementation options, so none of them is the right home for this work.

4. Question 4Business Modeling in a TOGAF context

   A product company wants a one-page view of how it creates and captures value, covering its target customers, value propositions, channels, revenue streams, and key partners, before detailed process work starts. Which business modelling aid best fits this need?

   1. AA sequence diagram that shows the order of messages exchanged between two software services over time
   2. BA high-level business model view that shows how value is created, delivered, and captured
   3. CAn entity-relationship diagram that shows the tables, keys, and relationships in the customer database
   4. DA network topology diagram that shows the physical links between the company's offices and data centres
   Show answer and explanationHide answer

   Correct answer: B

   A business model view shows how the enterprise creates, delivers, and captures value, which is the question the company is asking at this stage. The other three diagrams describe software interaction, data design, or physical infrastructure, which belong to later architecture work rather than to business modelling.

5. Question 5Business Capabilities and capability modeling

   Which statement best describes a business capability in TOGAF?

   1. AA specific sequence of tasks that a team follows to complete a customer order from start to finish
   2. BA software application that automates a single step in a business workflow and stores its own data
   3. CAn organizational unit with its own budget, headcount, and reporting line within the enterprise structure
   4. DAn ability that the business has, or can obtain from others, in order to achieve a specific purpose
   Show answer and explanationHide answer

   Correct answer: D

   A business capability is an ability the business possesses, or can obtain from others, to achieve a purpose. The other options describe a process, an organizational unit, and an application, which are different concepts that architects model separately.
