質問 # 10
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?

正解:C

解説:
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.


質問 # 11
Please read this scenario prior to answering the question
You are serving as the Lead Architect for an Enterprise Architecture team within a leading multinational biotechnology company. The company works in three major industries, including healthcare, crop production, and agriculture. Your team works within the healthcare division.
The healthcare division is developing a new vaccine, and has to demonstrate its effectiveness and safety in a set of clinical trials that satisfy the regulatory requirements of the relevant health authorities. The clinical trials are undertaken by its research laboratories at multiple facilities worldwide. In addition to internal research and development activities, the healthcare division is also involved in publicly funded collaborative research projects with industrial and academic partners.
The Enterprise Architecture team has been engaged in an architecture project to develop a secure system that will allow the healthcare researchers to share information more easily about their clinical trials, and work more collaboratively across the organization and also with its partners. This system will also connect with external partners.
The Enterprise Architecture team uses the TOGAF ADM with extensions required to support healthcare manufacturing practices and laboratory practices. Due to the highly sensitive nature of the information that is managed, special care has been taken to ensure that each architecture domain considers the security and privacy issues that are relevant.
The Vice President for Worldwide Clinical Research is the sponsor of the Enterprise Architecture activity. She has stated that disruptions must be minimized for the clinical trials, and that the rollout must be undertaken incrementally.
Refer to the scenario
You have been asked to recommend the approach to identify the work packages for an incremental rollout meeting the requirements.
Based on the TOGAF standard which of the following is the best answer?

正解:A


質問 # 12
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?

正解:B

解説:
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.

質問 # 13
Scenario:
You are working as an Enterprise Architect at a large company. The company runs a chain of home improvement stores, as well as a website for selling products. The website lets many brands work with the company.
The stores open seven days a week and use a standard method to track sales and inventory. This involves sending accurate and timely sales data to a central inventory management system that can predict demand, adjust stock levels, and automate reordering. The website is supported by regional fulfillment centers and also uses the central inventory management system. The central inventory management system is housed at the company's central data center.
The company has agreed to merge with a major competitor. The leadership teams of both organizations have said they are committed to a smooth transition for customers. All stores will keep their own brand names. They will combine the systems of the organizations, which includes merging retail operations and systems. Duplicated systems will be replaced with one standard retail management system. Additionally, they will reduce the number of applications being used. The CIO expects that these changes will lead to substantial cost savings for the newly merged company.
An enterprise plan for both organizations has been created. The aim is to set priorities for the transition, especially in terms of information management and application development. It is crucial to make decisions that will create long-term value.
The company has a mature Enterprise Architecture (EA) practice and uses the TOGAF standard for its architecture development method. The EA program is sponsored by the Chief Information Officer (CIO).
The Request for Architecture Work to oversee the transition has been approved. The project has been scoped, and you have been assigned to work on it.
You have been asked to confirm the most relevant architecture principles for the transition.
Based on the TOGAF Standard, which of the following is the best answer?

正解:D

解説:
The correct answer is C, as it aligns with the key TOGAF principles necessary for guiding enterprise architecture in a merger scenario where retail operations and systems are being consolidated.
Analysis of the Principles in Option C:
Common Use Applications
Since the two companies are merging, it is essential to standardize applications across the enterprise.
Using common applications ensures consistency, reduces costs, and improves efficiency.
TOGAF emphasizes this principle to prevent duplicate or redundant systems, which aligns with the CIO's goal of reducing the number of applications used.
Data is an Asset
In the scenario, a central inventory management system is a core business function.
Treating data as an asset ensures it is managed properly, shared efficiently, and used strategically across the merged organization.
This principle supports the company's ability to predict demand, adjust stock levels, and automate reordering.
Common Vocabulary and Data Definitions
The merger requires integrating different systems and data structures.
Having a common vocabulary ensures that all stakeholders (stores, fulfillment centers, and digital platforms) use consistent terminology and data definitions.
This minimizes confusion and ensures interoperability across business functions.
Maximize Benefit to the Enterprise
Every architectural decision should focus on the overall benefit to the business.
By consolidating IT systems and reducing redundancies, the company achieves cost savings, which directly supports this principle.
Business Continuity
The stores operate seven days a week, so system changes must ensure uninterrupted service.
Business continuity ensures that customers are not affected during the transition and that critical retail operations (sales, inventory tracking, and fulfillment) remain functional.
Why Other Options Are Incorrect?
Option A: Control Technical Diversity, Interoperability, Data is an Asset, Data is Shared, Business Continuity Control Technical Diversity is not the primary concern here. The focus is on system consolidation, not necessarily on limiting technology diversity.
Interoperability is important but not as critical as defining a common system and data structure.
Option B: Service Orientation, Compliance with the Law, Requirements-Based Change, Responsive Change Management, Data Security While service orientation and compliance are valuable, they are not the most relevant to this specific business transition.
Change management and data security are important but do not address the primary enterprise-wide architectural concerns of system consolidation.
Option D: Ease of Use, Common Use Applications, Data is an Asset, Technology Independence, Business Continuity Ease of Use is beneficial but is not a core architecture principle in this case.
Technology Independence is useful but does not align directly with the scenario's priority, which is consolidating applications and data structures.

質問 # 14
You are working as an Enterprise Architect at a large company. The company runs many retail stores as well as an online marketplace that allows hundreds of brands to partner with the company. The company has a mature Enterprise Architecture (EA) practice and uses the TOGAF standard for its architecture development method. The EA practice is involved in all aspects of the business, with oversight provided by an Architecture Board with representatives from different parts of the business. The EA program is sponsored by the Chief Information Officer (CIO).
Many of the stores remain open all day and night. Each store uses a standard method to track sales and inventory, which involves sending accurate, timely sales data to a central AI-based inventory management system that can predict demand, adjust stock levels, and automate reordering. The central inventory management system is housed at the company's central data center.
The company has acquired a major rival. The Chief Executive Officer (CEO) believes that the merger will enable growth through combined offerings and cost savings. The decision has been made to fully integrate the two organizations, including merging retail operations and systems. Duplicated systems will be replaced with one standard retail management system. The CIO expects significant savings from these changes across the newly merged company.
The rival company has successfully implemented the use of hand-held devices within stores for both customers and staff, which has increased satisfaction due to time savings. The CIO has approved the rollout of these devices to all stores but has stated that training should be brief, as there are many part-time employees.
You have been asked to confirm the most relevant architecture principles for this transformation. Based on the TOGAF Standard, which of the following is the best answer?

正解:C

解説:
In this scenario, the enterprise is undergoing significant transformation due to a merger and the adoption of new technology (hand-held devices). Several key principles from TOGAF ' s ADM Techniques-particularly those focused on promoting enterprise-wide standardization, adaptability, and data utilization-are pertinent here:
* Maximize Benefit to the Enterprise:This principle emphasizes that all architectural decisions should deliver maximum business value. Given that the company is integrating systems to cut costs and improve offerings, maximizing the benefit is crucial. Ensuring that the EA efforts align with enterprise- wide benefits supports the goal of optimizing costs and enhancing offerings, which aligns with the CEO' s vision for the merger.
* Common Use Applications:Standardizing applications across the merged entity will be essential to achieve cost savings and to simplify operations. The goal of reducing the number of applications fits with this principle, ensuring that reusable and widely adopted applications support business functions across the organization. Adopting this principle will also aid in harmonizing the systems from both organizations and avoiding unnecessary diversity.
* Data is an Asset:Data plays a central role in the company ' s operations, especially with the use of AI- driven inventory management and the integration of systems. Treating data as an asset is essential for reliable and accurate decision-making. This principle ensures that data is viewed as a critical enterprise resource and is managed with care, maintaining integrity, accuracy, and value.
* Responsive Change Management:The organization's ability to adapt quickly and effectively to changes, such as integrating new handheld devices and merging systems, is essential. This principle will facilitate the smooth transition required for integrating the new handheld devices and the merger-related system updates while minimizing disruption to store operations.
* Technology Independence:Since the enterprise will likely encounter varied technologies from the merger, it is crucial to maintain flexibility. This principle advocates for using technology solutions that are adaptable and not bound to a single vendor or specific technology. This ensures that the enterprise can integrate various technological components from both organizations and evolve with minimal constraints.
These principles align well with TOGAF ' s broader recommendations for guiding architectural changes, as found in Section 2.6 of the TOGAF ADM Techniques. They ensure that the EA practice is aligned with business objectives while maintaining flexibility, data integrity, and a focus on enterprise-wide benefits.
These guiding principles are critical for the successful execution of the integration and adoption of new technologies while achieving cost efficiencies and improving service delivery.
For reference, TOGAF ' s ADM Techniques highlight the importance of architectural principles in guiding transformational initiatives, ensuring that decisions are made consistently across the enterprise. Each principle supports organizational agility, system integration, and the efficient use of technology resources, all of which are vital for the enterprise ' s stated objectives.
