質問 # 18
Please read this scenario prior to answering the question
Your role is that of a senior architect, reporting to the Chief Enterprise Architect, at a medium-sized company with 400 employees. The nature of the business is such that the data and the information stored on the company systems is their major asset and is highly confidential.
The company employees travel extensively for work and must communicate over public infrastructure using message encryption, VPNs, and other standard safeguards. The company has invested in cybersecurity awareness training for all its staff. However, it is recognized that even with good education as well as system security, there is a dependency on third-parly suppliers of infrastructure and software.
The company uses the TOGAF standard as the method and guiding framework for its Enterprise Architecture (EA) practice. The CTO is the sponsor of the activity.
The Chief Security Officer (CSO) has noted an increase in ransomware (malicious software used in ransom demands) attacks on companies with a similar profile. The CSO recognizes that no matter how much is spent on education, and support, it is likely just a matter of time before the company suffers a significant attack that could completely lock them out of their information assets.
A risk assessment has been done and the company has sought cyber insurance that includes ransomware coverage. The quotation for this insurance is hugely expensive. The CTO has recently read a survey that stated that one in four organizations paying ransoms were still unable to recover their data, while nearly as many were able to recover the data without paying a ransom. The CTO has concluded that taking out cyber insurance in case they need to pay a ransom is not an option.
Refer to the scenario
You have been asked to describe the steps you would take to improve the resilience of the current architecture?
Based on the TOGAF standard which of the following is the best answer?
正解:C
解説:
Business continuity is the ability of an organization to maintain essential functions during and after a disaster or disruption. Business continuity requirements are the specifications and criteria that define the acceptable level of performance and availability of the business processes and services in the event of a disaster or disruption. A gap analysis is a technique that compares the current state of the architecture with the desired state, and identifies the gaps or differences that need to be addressed. A change request is a formal proposal for an amendment to some product or system, such as the architecture. A Request for Architecture Work is a document that describes the scope, approach, and expected outcomes of an architecture project123 The best answer is A, because it describes the steps that would improve the resilience of the current architecture, which is the ability to withstand and recover from a ransomware attack or any other disruption. The steps are:
Determine the business continuity requirements, which specify the minimum acceptable level of performance and availability of the business processes and services in case of a ransomware attack. This would involve identifying the critical business functions, the recovery time objectives, the recovery point objectives, and the dependencies and resources needed for recovery.
Undertake a gap analysis of the current Enterprise Architecture, which compares the current state of the architecture with the desired state based on the business continuity requirements. This would involve assessing the strengths and weaknesses of the current architecture, the risks and opportunities for improvement, and the gaps or differences that need to be addressed.
Make recommendations for change requirements to address the situation and create a change request. This would involve proposing solutions and alternatives to close the gaps, enhance the resilience, and mitigate the risks of the current architecture. The change request would document the rationale, scope, impact, and benefits of the proposed changes, and seek approval from the relevant stakeholders.
Manage a meeting of the Architecture Board to assess and approve the change request. The Architecture Board is a governance body that oversees the architecture work and ensures compliance with the architecture principles, standards, and goals. The meeting would involve presenting the change request, discussing the pros and cons, resolving any issues or conflicts, and obtaining the approval or rejection of the change request.
Once approved, produce a new Request for Architecture Work to activate an ADM cycle to carry out a project to define the change. The Request for Architecture Work would describe the scope, approach, and expected outcomes of the architecture project that would implement the approved change request. The Request for Architecture Work would initiate 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 architecture.

質問 # 19
You are working as an Enterprise Architect within an Enterprise Architecture (EA) team at a multinational energy company. The company is committed to becoming a net-zero emissions energy business by 2050. To achieve this, the company is focusing on shifting to renewable energy production and adopting eco-friendly practices.
The EA team, which reports to the Chief Technical Officer (CTO), has been tasked with overseeing the transformation to make the company more effective through acquisitions. The company plans to fully integrate these acquisitions, including merging operations and systems.
To address the integration challenges, the EA team leader wants to know how to manage risks and ensure that the company succeeds with the proposed changes. Based on the TOGAF Standard, which of the following is the best answer?
正解:B
解説:
In TOGAF, creating a Business Scenario is a foundational step in defining and understanding the business problem, especially for complex transformations involving multiple stakeholders and systems, such as in this scenario. This method aligns with Phase A (Architecture Vision) of the TOGAF Architecture Development Method (ADM). Here's why this approach is the most effective:
Understanding Business Requirements:
A Business Scenario provides a structured way to capture and analyze the business requirements, stakeholder concerns, and the contextual elements related to the problem. In this scenario, the company faces challenges in integrating newly acquired companies with existing operations, which includes complex stakeholder concerns across different functional areas. Developing a Business Scenario allows the EA team to break down these complexities into identifiable and manageable parts.
Risk Evaluation and Management:
By using the Business Scenario approach, the EA team can not only define the requirements but also assess associated risks systematically. TOGAF emphasizes the importance of risk management through identifying potential risks, evaluating their impact, and defining strategies for handling these risks. The process includes assessing how risks can be avoided, transferred, or reduced-a necessary step in large-scale transformations to ensure that risks are proactively managed.
Residual Risks and Governance:
Any risks that cannot be fully resolved should be identified as residual risks and escalated to the Architecture Board, which is aligned with TOGAF's governance approach. The Architecture Board's role in TOGAF is to provide oversight and make critical decisions on risks that exceed the control of the EA team. This ensures that unresolved risks are managed at the appropriate level of the organization.
Alignment with TOGAF ADM Phases:
The Business Scenario approach directly aligns with the Preliminary and Architecture Vision phases of the TOGAF ADM, which focuses on establishing a baseline understanding of the business context and the strategic transformation required. The detailed understanding of requirements, stakeholder concerns, and risks identified here will guide the subsequent phases of the ADM, including Business Architecture and Information Systems Architecture.
TOGAF Reference (Section 2.6, ADM Techniques):
TOGAF provides guidelines on the creation of Business Scenarios as part of ADM Techniques, highlighting the importance of defining a business problem comprehensively to ensure successful transformation. This method includes identification of stakeholders, business requirements, and associated risks, which aligns well with the company's need for strategic and systematic integration of new business units.
By utilizing a Business Scenario, the EA team ensures that all aspects of the transformation are well understood, risks are identified early, and residual risks are managed effectively, aligning with the company's strategic objectives and the TOGAF framework's guidance on risk management and stakeholder alignment.

Your role is consultant to the Lead Architect within a multinational company that manufactures electronic components. The company has several manufacturing divisions located worldwide and a complex supply chain. After a recent study, senior management have stated a concern about business efficiency considering the company's multiple data centers and duplication of applications.
The company has a mature Enterprise Architecture (EA) practice and uses the TOGAF architecture development method in its EA practice. In addition to the EA program, the company has several management frameworks in use, including business planning, project/portfolio management, and operations management. The EA program is sponsored by the CIO.
A strategic architecture has been defined to improve the ability to meet customer demand and improve management of the supply chain. The strategic architecture includes the consolidation of multiple Enterprise Resource Planning (ERP) applications that have been operating independently in the divisions' production facilities.
Each division has completed the Architecture Definition documentation to meet its own specific manufacturing requirements. The enterprise architects have defined a set of work packages that address the gaps identified. They have identified the value produced, effort required, and dependencies between work packages to reach a farget architecture that would integrate a new ERP environment into the company.
Because of the risks posed by change from the current environment, the architects have recommended that a phased approach occurs to implement the target architecture with several transition states. The overall implementation process is estimated to take several years.
Refer to the scenario
You have been asked what the next steps are for the migration planning.
Based on the TOGAF standard which of the following is the best answer?
正解:D
解説:
The Business Value Assessment Technique is a technique that can be used to estimate and compare the business value of the projects and project increments that implement the architecture work packages, which are the sets of actions or tasks that are required to implement a specific part of the architecture. The business value is the measure of the benefits or advantages that the project or project increment delivers to the business, such as increased revenue, reduced costs, improved quality, or enhanced customer satisfaction1 The steps for applying the Business Value Assessment Technique are:
Identify the criteria and factors that are relevant to the business value assessment, such as costs, benefits, risks, and opportunities. The criteria and factors should be aligned with the business goals and drivers that motivate the architecture work, and the stakeholder requirements and concerns that influence the architecture work.
Assign weights and scores to the criteria and factors, using various methods, such as expert judgment, historical data, or analytical models. The weights and scores should reflect the importance and performance of the criteria and factors, and the trade-offs and preferences of the stakeholders.
Calculate the business value for each project or project increment, using various techniques, such as net present value, return on investment, or balanced scorecard. The business value should indicate the expected or actual outcomes and impacts of the project or project increment on the business.
Prioritize the implementation projects and project increments, based on the business value and other considerations, such as dependencies, resources, or risks. The prioritization should determine the order or sequence of the projects and project increments, and the allocation and utilization of the resources.
Therefore, the best answer is C, because it describes the next steps for the migration planning, which are the activities that support the transition from the Baseline Architecture to the Target Architecture. The answer covers the Business Value Assessment Technique, which is relevant to the scenario.
質問 # 22
You are working as an Enterprise Architect within the Enterprise Architecture (EA) team at a healthcare and life sciences company. The EA team is developing a secure system for researchers to share clinical trial information easily across the organization and with external partners.
Due to the highly sensitive nature of the information, each architecture domain must consider privacy and safety concerns. The healthcare division has been directed to minimize disruptions to clinical trials while introducing the new system gradually.
How would you identify the work packages for introducing the new system? Based on the TOGAF standard, which of the following is the best answer?
正解:C
解説:
In the TOGAF framework, understanding and addressing stakeholder concerns is crucial, particularly for complex projects with high stakes like the AI-first initiative described in the scenario. This approach aligns well with TOGAF's ADM (Architecture Development Method) and its emphasis on effective stakeholder management and risk assessment. Here's why this is the best course of action:
Stakeholder Analysis and Documentation:
Conducting a stakeholder analysis is foundational in the early stages of any TOGAF project, particularly during the Preliminary and Architecture Vision phases. This process involves identifying the different stakeholders, understanding their positions, documenting their concerns, and considering any cultural factors that might influence their perspective on the AI-first initiative. Given the diverse concerns raised (such as job security, skill requirements, and cybersecurity), it's essential to have a clear understanding of each stakeholder group's priorities and fears.
Recording Concerns in the Architecture Vision Document:
The Architecture Vision phase in TOGAF focuses on defining the high-level scope and objectives of the architecture project. By documenting stakeholder concerns and the corresponding views in the Architecture Vision document, the EA team ensures that these concerns are transparently acknowledged and addressed as part of the strategic direction. This step not only aligns with TOGAF best practices but also helps in building stakeholder buy-in and trust.
Architecture Requirements Specification and Risk Management:
Risk management is a key aspect of TOGAF's ADM, particularly in the Requirements Management and Implementation Governance phases. Documenting the requirements for addressing specific risks in the Architecture Requirements Specification provides a structured way to ensure that identified risks are acknowledged and managed throughout the transformation. Regular assessments and feedback loops ensure ongoing alignment and adaptability to emerging risks, which is particularly important given the dynamic nature of AI and its associated challenges.
Alignment with TOGAF ADM Phases:
This approach follows the prescribed flow of TOGAF's ADM, starting with stakeholder engagement in the Preliminary and Architecture Vision phases and progressing to risk assessment in the Requirements Management phase. By maintaining a focus on stakeholder needs and formalizing these into architecture requirements, the EA team can ensure that the architecture not only meets business objectives but also mitigates stakeholder concerns.
TOGAF Reference on Stakeholder Management Techniques:
TOGAF places significant emphasis on managing stakeholder concerns through its stakeholder management techniques, which highlight the need to systematically identify, analyze, and address the concerns of all involved parties. This practice helps ensure that the architecture is viable and accepted across the organization.
By conducting a thorough stakeholder analysis and integrating the findings into both the Architecture Vision and the Architecture Requirements Specification, the EA team can proactively address stakeholder concerns, manage risks, and align the AI-first initiative with the agency's strategic objectives. This approach is consistent with TOGAF's guidance and provides a structured framework for addressing both business and technical challenges in the context of an AI-first transformation.
