The Open Group TOGAF Enterprise Architecture Part 2 Exam Sample Questions (Q20-Q25):

NEW QUESTION # 20
Please read this scenario prior to answering the question
You are employed as an Enterprise Architect at a technology company, reporting directly to the Chief Enterprise Architect. The company supplies personnel and delivers cloud- based solutions to numerous government agencies.
The nature of the business is such that the data and the information stored on the company systems is the company's major asset and is highly confidential. The company employees work remotely and need constant access to the company systems, which is done by the public infrastructure. They use message encryption, secure internet connections using Virtual Private Networks (VPNs), and other standard security measures. The company provides computer security awareness training for all its staff.
The Chief Security Officer (CSO) has noted an increase in distributed denial of service (DDoS) attacks on companies with a similar profile. The CSO understands that even with thorough preparation, a major attack could stop employees from being able to do their jobs. This could lead to a large financial loss, damage to the company's reputation with customers, and employees being unable to work.
A risk assessment has been completed and the company has looked for cyber insurance that covers such attacks. The price for this insurance is very high. The CTO has decided not to get cyber insurance to cover such attacks.
The company follows the TOGAF standard as the method and guiding framework for its Enterprise Architecture (EA) practice. The Chief Technology Officer (CTO) is the sponsor of the activity. The practice uses an iterative approach for its architecture development.
This has enabled the decision makers to gain valuable insights into the different aspects of the business Please read this scenario prior to answering the question You have been asked to describe the steps you would take to strengthen the current architecture to improve data protection.
Based on the TOGAF standard which of the following is the best answer?

Answer: B

Explanation:
In this scenario, the CTO has not purchased cyber-insurance, the CSO is concerned about increased DDoS risk, and YOU (the EA) are asked "to describe the steps you would take to strengthen the current architecture to improve data protection." Because the company follows the TOGAF standard and uses an iterative ADM cycle, the correct response must:
Start with the risk/continuity concern
Use the formal TOGAF change management process
Lead to a Request for Architecture Work
Initiate a new ADM cycle to update the architecture properly
Ensure Architecture Board governance
Option B is the only answer that matches TOGAF's required process.
✔ Why Option B is correct (TOGAF-aligned)
Option B follows TOGAF's Architecture Change Management (Phase H) process:
Assess the business continuity requirements
- Correct: Phase H requires evaluating change triggers such as new risks, threats, or incidents.
- DDoS risk → business continuity concern → legitimate architecture change trigger.
Analyze the current architecture for gaps
- Correct: TOGAF Phase H requires assessing whether the current baseline architecture can support required resilience.
Create a formal Change Request
- Exactly correct: Phase H outputs Architecture Change Requests (ACRs) for significant changes.
- ACR includes description, rationale, and impact (in this case: resilience, continuity, and data protection).
Architecture Board reviews/approves the change request
- Correct: All major architecture changes must go through Architecture Governance.
Create a new Request for Architecture Work (RFAW)
- Required when the change is significant and needs a new ADM cycle.
- Strengthening data protection and business continuity DEFINITELY qualifies as a major change.
Begin a new ADM cycle to implement the changes
- Perfectly aligned with TOGAF's iterative approach:
Business continuity → update Technology Architecture → updated security patterns → updated Target Architecture.
This is exactly the TOGAF-prescribed method to strengthen an architecture when significant new risks appear.
Therefore, Option B is the correct and TOGAF-compliant answer.
✘ Why the other options are incorrect
A - Not TOGAF-aligned
Starts with vendors and simulations (not TOGAF-first steps).
No mention of Architecture Board or Change Management.
No Request for Architecture Work.
Gap analysis alone is not the first step for significant architectural risk.
C - Too narrow and skips TOGAF governance
Jumps straight to modifying the Technology Architecture baseline.
No Change Request, no RFAW, no ADM cycle initiation.
Recommends a solution ("DDoS mitigation at infrastructure level") before architectural assessment.
D - Misuses Architecture Compliance Review
Architecture Compliance Reviews check conformity to an existing architecture-not evaluate new risks or design resilience enhancements.
A compliance review is not the correct first step for addressing new threats.


NEW QUESTION # 21
You are working as an Enterprise Architect within an Enterprise Architecture (EA) team at a large government agency with multiple divisions. The agency has a well-established EA practice and follows the TOGAF standard as its method for architecture development. The government has mandated that the agency prepare for an "AI-first" world.
The agency wants to determine the impact and role of AI in its future services. The CIO has approved a Request for Architecture Work to explore the use of AI in services. Some leaders are concerned about reliance on AI, security, and employees' need to acquire new skills.
The EA team leader seeks suggestions on managing the risks associated with a new architecture for the AI-first project. Based on the TOGAF standard, which of the following is the best answer?

Answer: B


NEW QUESTION # 22
Please read this scenario prior to answering the question
You have been appointed as senior architect working for an autonomous driving technology development company. The mission of the company is to build an industry leading unified technology and software platform to support connected cars and autonomous driving.
The company uses the TOGAF Standard as the basis for its Enterprise Architecture (EA) framework. Architecture development within the company follows the purpose-based EA Capability model as described in the TOGAF Series Guide: A Practitioners'Approach to Developing Enterprise Architecture Following the TOGAF® ADM.
An architecture to support strategy has been completed defining a long-range Target Architecture with a roadmap spanning five years. This has identified the need for a portfolio of projects over the next two years. The portfolio includes development of travel assistance systems using swarm data from vehicles on the road.
The current phase of architecture development is focused on the Business Architecture which needs to support the core travel assistance services that the company plans to provide. The core services will manage and process the swarm data generated by vehicles, paving the way for autonomous driving in the future.
The presentation and access to different variations of data that the company plans to offer through its platform poses an architecture challenge. The application portfolio needs to interact securely with various third-party cloud services, and V2X (Vehicle-to-Everything) service providers in many countries to be able to manage the data at scale. The security of V2X is a key concern for the stakeholders. Regulators have stated that the user's privacy be always protected, for example, so that the drivers' journey cannot be tracked or reconstructed by compiling data sent or received by the car.
Refer to the scenario
You have been asked to describe the risk and security considerations you would include in the current phase of the architecture development?
Based on the TOGAF standard which of the following is the best answer?

Answer: C

Explanation:
A security domain model is a technique that can be used to define the security requirements and policies for the architecture. A security domain is a grouping of assets that share a common level of security and trust. A security policy is a set of rules and procedures that govern the access and protection of the assets within a security domain. A security domain model can help to identify the security domains, the assets within each domain, the security policies for each domain, and the relationships and dependencies between the domains1 Since the data is being shared across partners, a security federation is needed to establish a trust relationship and a common security framework among the different parties. A security federation is a collection of security domains that have agreed to interoperate under a set of shared security policies and standards. A security federation can enable secure data exchange and collaboration across organizational boundaries, while preserving the autonomy and privacy of each party. A security federation requires contractual arrangements, and a definition of the responsibility areas for the data exchanged, as well as security implications2 A risk assessment is a process that identifies, analyzes, and evaluates the risks that may affect the architecture. A risk assessment can help to determine the likelihood and impact of the threats and vulnerabilities that may compromise the security and privacy of the data assets. A risk assessment can also help to prioritize and mitigate the risks, and to monitor and review the risk situation3 Therefore, the best answer is D, because it describes the risk and security considerations that would be included in the current phase of the architecture development, which is focused on the Business Architecture. The answer covers the security domain model, the security federation, and the risk assessment techniques that are relevant to the scenario.


NEW QUESTION # 23
Please read this scenario prior to answering the question
You are employed as an Enterprise Architect at a large technology company with diverse business lines. The company has multiple divisions, engaged in mobile, e-commerce, cloud computing services, and a social network.
The company has an established Enterprise Architecture (EA) practice based on the TOGAF standard, including the TOGAF ADM. The EA program is sponsored by the Chief Information Officer (CIO). The use of EA has enabled the company to gain valuable insights into different parts of the business. One of the primary goals in the EA program charter is to coordinate efforts between the teams in each division. This has made sure that the mobile, e-commerce, cloud, and social media initiatives remain aligned with business strategy.
The practice has an established Architecture Capability and uses iteration for architecture development. The iterative approach is well-suited for modern digital transformation initiatives, where the company must adapt quickly to new business and market challenges. In addition to the EA program, the company uses several management frameworks, including business planning, project/portfolio management, and operations management.
The company is growing rapidly. A consequence of this rapid growth has been the proliferation of multiple IT solutions, with architecture giving way to growth. The company appears to be failing to architect its growth.
Several systems have proved unreliable with some major outages, including the e-commerce system being offline for eight hours at the start of the holiday sales period, as well as the cloud computing services outage, which took down several popular websites. The service management organization within the company has blamed the outages on misalignment of the IT solutions.
The Governing Board has raised concerns about the outages. As a consequence, the CEO has asked for better reporting and management of the IT portfolio. The task has been assigned to the EAteam, with a constraint to maintain business as usual.
Refer to the Scenario
You have been asked to assess the IT solutions to determine where problems are occurring and where change is needed.
Based on the TOGAF standard, which of the following is the best answer?

Answer: D

Explanation:
D is the best answer because the assignment is diagnostic: assess existing IT solutions, determine where problems are occurring, and identify where change is needed while maintaining business as usual. TOGAF supports different ADM iteration styles, including a baseline-first approach when the current landscape is complex, poorly understood, or suspected of containing misalignment. The company has grown quickly, accumulated multiple IT solutions, and experienced serious operational outages. The right architectural response is therefore to evaluate current IT resources against business needs and operational performance data, including availability and responsiveness. This must cover both applications and technology infrastructure because the problem is not necessarily only infrastructure capacity; it may involve application dependencies, service coupling, integration weaknesses, duplicated solutions, or portfolio fragmentation. A is too narrow because it starts only with Technology Architecture. B is premature because it starts by defining a target before understanding the baseline failure pattern. C is broader than A but less precise because it frames the work as a full B-D architecture definition cycle rather than a baseline-first assessment focused on portfolio and operational misalignment. References: Applying the ADM; Iteration; Baseline-first architecture development; Architecture Portfolio Management; Operational performance assessment.


NEW QUESTION # 24
Please read this scenario prior to answering the question
You are the Lead Enterprise Architect at a major agribusiness company. The company's main harvest is lentils, a highly valued food grown worldwide. The lentil parasite, broomrape, has been an increasing concern for many years and is now becoming resistant to chemical controls. In addition, changes in climate favor the propagation and growth of the parasite. As a result, the parasite cannot realistically be exterminated, and it has become pandemic, with lentil yields falling globally.
In response to the situation, the CEO has decided that the lentil fields will be used for another harvest. The company will also cease to process third-party lentils and will repurpose its processing plants. Thus, the target market will change, and the end-products will be different and more varied.
The company has recently established an Enterprise Architecture practice based on the TOGAF standard as method and guiding framework. The CIO is the sponsor of the activity. A formal request for architecture change has been approved. At this stage there is no fixed scope, shared vision, or objectives.
Refer to the scenario
You have been asked to propose the best approach for architecture development to realize the CEO's change in direction for the company.
Based on the TOGAF standard which of the following is the best answer?

Answer: D

Explanation:
A Request for Architecture Work is a document that describes the scope, approach, and expected outcomes of an architecture project. A Request for Architecture Work is usually initiated by the sponsor or client of the architecture work, and approved by the Architecture Board, which is a governance body that oversees the architecture work and ensures compliance with the architecture principles, standards, and goals. A Request for Architecture Work triggers a new cycle of the Architecture Development Method (ADM), which is the core process of the TOGAF standard that guides the development and management of the enterprise architecture12 An Architecture Vision is a high-level description of the desired outcomes and benefits of the proposed architecture. An Architecture Vision is the output of Phase A: Architecture Vision of the ADM cycle, which is the first phase of the architecture development. An Architecture Vision defines the scope and approach of the architecture work, and establishes the business goals and drivers that motivate the architecture work. An Architecture Vision also involves obtaining the approval and commitment of the sponsors and other key stakeholders, and initiating the Architecture Governance process3 A trade-off analysis is a technique that can be used to evaluate and compare different architecture alternatives and select the most suitable one. A trade-off analysis involves identifying the criteria and factors that are relevant to the decision, such as costs, benefits, risks, and opportunities, and assessing the strengths and weaknesses of each alternative. A trade-off analysis also involves balancing and reconciling the multiple, often conflicting, requirements and concerns of the stakeholders, and ensuring alignment with the Architecture Vision and the Architecture Principles.
Therefore, the best answer is D, because it proposes the best approach for architecture development to realize the CEO's change in direction for the company. The answer covers the Request for Architecture Work, the Architecture Vision, and the trade-off analysis techniques that are relevant to the scenario.
