The Open Group OGEA-102 問題集

質問 1：
Please read this scenario prior to answering the question
You are working as an Enterprise Architect at a large supermarket. The company runs many retail stores, as well as an online grocery shop. Many of the stores used to remain open 24/7, but the number has decreased in recent years. Instead, they now focus on fulfilling online orders during the night.
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).
Each store uses a standard method to track sales and inventory. This involves sending accurate timely sales data to a central Al-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 bought a major rival. The Chief Executive Officer believes that a merger will enable growth through combined offerings and cost savings. The decision has been taken to fully integrate the two organizations, including merging retail operations and systems. This means that duplicated systems will be replaced with one standard retail management system. Also, the company will reduce the number of applications that are used. The CIO expects significant savings will be achieved by implementing these changes across the newly merged company.
One improvement that the rival has successfully implemented is the use of hand-held devices within stores, for both customers and staff. This has increased both customer and staff employee satisfaction due to the time savings this has brought. The CIO has given the go-ahead to roll out the devices in all stores but has stated that training on how to use the hand-held devices should be brief because there are a lot of employees, many of whom are part-time.
The Request for Architecture Work to oversee the merger has been approved. The project has been scoped and you have been assigned to work on it. Your role includes managing the architecture for the retail stores.

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?
A. You would ensure that business value and cost of continuity measures areunderstood by key stakeholders, and that the company has in place up-to-dateprocesses for managing change to the current Enterprise Architecture. Yourecommend that DDoS mitigation be addressed at the infrastructure level toensure effective, scalable protection. Changes should be made to the baselinedescription of the Technology Architecture. The changes should be approvedby the Architecture Board and implemented by change managementtechniques.
B. You would run a planning exercise to assess the business continuityrequirements and analyze the current Enterprise Architecture for gaps. Youcreate a formal change request related to business resilience and maintainingcritical business functions. You would arrange a meeting of the ArchitectureBoard to assess and approve the change request. Once approved you wouldcreate a new Request for Architecture Work to begin an ADM cycle toimplement the changes.
C. You would hold an Architecture Compliance Review with the scope to examinethe company's ability to respond to such attacks. You would identify thedepartments involved and have them nominate representatives. You wouldthen tailor checklists to address the requirement for increased businesscontinuity and resilience. You would circulate the checklists to the nominatedrepresentatives for them to complete. You would review the completedchecklists, identifying and resolving issues. You would then determine andpresent your recommendations to the Architecture Board.
D. You would request technology updates from existing suppliers that improve thecompany's capabilities to detect, react, and recover from an incident. Youwould run a simulated ransomware attack to evaluate the current EnterpriseArchitecture's resilience and recovery capabilities. Using the findings, youwould perform a gap analysis of the current Enterprise Architecture, andprepare change requests to address identified gaps. You would document thechanges implemented and add to the Architecture Repository.

Scenario:
You are working as an Enterprise Architect within a company providing legal services. The company operates in many countries and has a complicated structure. Every office must follow the local regulations in their country.
The company's Enterprise Architecture (EA) department has been operating for several years and has mature, well-developed architecture governance and development processes based on the TOGAF standard. In addition to the EA program, the company has several management frameworks, including business planning, project/portfolio management, and operations management. The Architecture Board includes representatives from all parts of the company.
The Chief Information Officer (CIO) is the sponsor of the Enterprise Architecture program. The CIO has actively encouraged architecting with agility within the EA department as the preferred approach for projects. The CIO has given approval for a Request for Architecture Work to explore the adoption of an AI-powered system for managing legal cases and financial processes.
Senior management has become more concerned about business performance, especially with the advancements in Artificial Intelligence (AI). Many of the company's competitors have started using AI to assist with legal strategies, streamline processes, and boost productivity. One of the most important benefits AI has for the business is its ability to increase accuracy and minimize mistakes.
Some of the top managers are worried about a change in the way of working, and if it will achieve the business goals. Their staff also fear that management will use the AI system to measure their performance. The CIO wants to know how to address these concerns and reduce risks.
The new system is expected to guide legal professionals and analysts on which tasks to focus on. The main goals are to improve productivity and make better use of staff. In addition, the CIO hopes these changes will lead to higher customer satisfaction.
Refer to the scenario:
You have been asked to respond to the Chief Information Officer (CIO) recommending an approach that would enable the development of an architecture that addresses the concerns of the top managers and the multiple branches in different parts of the company.
Based on the TOGAF standard, which of the following is the best answer?
A. You recommend that an analysis of the stakeholders is undertaken. This will allow the architects to define groups of partners (the stakeholders) who have common concerns and include development of a Stakeholder Map. The concerns and relevant views should then be defined for each group and recorded in the Architecture Vision document. To reduce risk, you include a requirement that there be progressive development of the target architecture to get regular feedback.
B. You recommend that a Communications Plan be created to address the key stakeholders, particularly influential partners. This plan should include a report summarizing the key features of the architecture with respect to each location and reflect the stakeholders' requirements. You will check with each key stakeholder that their concerns have been addressed. Risk mitigation should be explicitly addressed as a component of the architecture being developed.
C. You recommend creation of a set of business models that can be applied uniformly across all AI-related architecture projects. These should be developed in a portable format to ensure maximum portability across the many tools used in the firm. Each architecture should then be defined based on this fixed set of models. All concerned stakeholders can then examine the models to ensure that their needs have been addressed.
D. You recommend that models be created for each of the Business, Application, and Technology architectures. These can be used to ensure that the system will be compliant with the local regulations for each operating entity. This ensures that all necessary data and detail is addressed. A formal review should be held with the stakeholders to verify that their concerns have been properly addressed by the models.

Scenario
You are working as an Enterprise Architect within a large manufacturing company. The company has multiple divisions located worldwide.
After a recent study, senior management is concerned about the impact of the company's multiple data centers and duplication of applications on business efficiency. To address this concern, a strategic architecture has been defined; it will help improve the ability to meet customer demand and improve the efficiency of operations. The strategic architecture involves the consolidation of multiple application programs that are currently used in different divisions and putting them all onto a cloud-based solution instead.
Each division has completed the Architecture Definition documentation to meet its own specific operational requirements. The enterprise architects have analyzed the corporate changes and implementation constraints. A consolidated gap analysis has been completed. Based on its results, the architects have reviewed the requirements, dependencies, and interoperability requirements needed to integrate the cloud-based solution. The architects have completed the Business Transformation Readiness Assessment. Based on all these factors, they have produced a risk assessment. They have also completed the draft Implementation and Migration Plan, the draft Architecture Roadmap, and the Capability Assessment deliverables.
Due to the risks of changing from the current environment, the decision has been taken that a gradual approach is needed to implement the target architecture. It will likely take a few years to complete the whole implementation process.
The company has a mature Enterprise Architecture (EA) practice and uses the TOGAF standard for its architecture development method. The EA practice is engaged throughout all the divisions, with implementation governance assigned to a business line. In addition to providing guidance on using architecture frameworks, including business planning, project/portfolio management, and operations management, the EA program is sponsored by the Chief Information Officer (CIO).
You have been asked to decide on the next steps for the migration planning.
Based on the TOGAF standard, which of the following is the best answer?
A. You conduct a series of Compliance Assessments to ensure that the architecture is being implemented according to the contract. The Compliance Assessment verifies that the implementation team is using the proper development methodology. It should include deployment of monitoring tools and ensure that performance targets are being met. If they are not met, then you would identify changes to performance requirements and update those in the Implementation and Migration Plan.
B. You update the Architecture Definition Document, which includes setting project objectives and documenting the final requirements. This will ensure that the architecture remains relevant and responsive to the needs of the enterprise. You then produce an Implementation Governance Model to manage the lessons learned prior to finalizing the Implementation and Migration Plan. You recommend that lessons learned be applied as changes to the architecture without review.
C. You assess the business value for each project by applying the Business Value Assessment Technique. The assessment should focus on return on investment and performance evaluation criteria to prioritize the most progress of the architecture transformation. You confirm and plan a series of Transition Architecture phases using an Architecture Definition Increments Table. You document the lessons learned and generate the final Implementation and Migration Plan.
D. You examine how the Implementation and Migration Plan affects the other frameworks being used in the organization. You coordinate the planning with the business planning, project/portfolio management, and operations management frameworks. You assign a business value to each project, considering the available resources and how well they align with the strategy. You then update the architecture roadmap and the Implementation and Migration Plan.
