The Open Group TOGAF Enterprise Architecture Part 2 Sample Questions:

1. Scenario
Your role is that of an Enterprise Architect, reporting to the Chief Enterprise Architect, at a technology company.
The company uses 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 EA 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.
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 travel a lot for work and need to communicate over public infrastructure. They use message encryption, secure internet connections using Virtual Private Networks (VPNs), and other standard security measures. The company has provided computer security awareness training for all its staff. However, despite good education and system security, there is still a need to rely on third-party suppliers for infrastructure and software.
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, the company could be a victim of a significant attack that could completely lock them out of their important data.
A risk assessment has been completed, and the company has looked for cyber insurance that covers ransomware. The price for this insurance is very high. The CTO recently saw a survey that said 1 out of 4 businesses that paid ransoms could not get their data back, and almost thesame number were able to recover the data without paying. The CTO has decided not to get cyber insurance to cover ransom payment.
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 the company has in place up-to-date processes for managing change to the current Enterprise Architecture. Based on the scope of the concerns raised, you recommend that this be managed at the infrastructure level. Changes should be made to the baseline description of the Technology Architecture. The changes should be approved by the Architecture Board and implemented by change management techniques.
B) You would request an Architecture Compliance Review with the scope to examine the company's ability to respond to ransomware attacks. You would identify the departments involved and have them nominate representatives. You would then tailor checklists to address the requirement for increased resilience. You would circulate to the nominated representatives for them to complete. You would then review the completed checklists, identifying and resolving issues. You would then determine and present your recommendations.
C) You would assess business continuity requirements and analyze the current Enterprise Architecture for gaps. You would recommend changes to address the situation and create a change request. You would engage the Architecture Board to assess and approve the change request. Once approved, you would create a new Request for Architecture Work to begin an ADM cycle to implement the changes.
D) You would monitor for technology updates from your existing suppliers that could enhance the company's capabilities to detect, react, and recover from an IT security incident. You would prepare and run a disaster recovery planning exercise for a ransomware attack and analyze the performance of the current Enterprise Architecture. Using the findings, you would prepare a gap analysis of the current Enterprise Architecture. You would prepare change requests to address identified gaps. You would add the changes implemented to the Architecture Repository.

2. Please read this scenario prior to answering the question
You are employed as an Enterprise Architect in a team at a large company. The company sells luxury food and drinks in more than 10,000 stores worldwide. The company is a leader in using technology to connect with its customers. This includes online ordering, mobile apps, and rewards programs. The company is also famous for bringing new ideas to the market, like ordering through apps, using Al to suggest personalized options, self-service pickup stations, and changing prices based on demand.
The stores are open every day. They send timely sales data to a central system that manages inventory. This system can predict what products are needed, adjust how much stock there is, and order more stock automatically. The stores and the main inventory system work directly with the mobile apps, allowing orders to be made online. The central inventory system is located at the company's main data center.
The company will merge with a major competitor. This competitor has a synergistic business. Leaders from both companies have told shareholders that the merger will happen fast. There will be minimal impact for customers. All stores will keep the current brand names. They will combine their systems, choosing the best ones to use.
This means their store management and back-office systems will become one. They will stop using duplicate systems and use one main system to manage the stores.
They will also cut down on the number of back-office applications they use.
The Request for Architecture Work to oversee the merger has been approved.
Stakeholders, concerns, and business requirements have been identified. The stakeholders have made it clear that they expect to continue to be able to innovate quickly, and that changes should not restrict that capability. The scope of what is inside and what is outside the architecture efforts has been confirmed. The next step is to revisit and review the Architecture Principles, as they form part of the constraints on architecture work.
Business Continuity is essential given that the business depends on real-time ordering and automated inventory management. During the systems integration, maintaining service for customers and inventory operations must be prioritized Refer to the scenario You have been asked to identify the most relevant Architecture Principles for the merger besides Business Continuity.
Based on the TOGAF standard, which of the following is the best answer?
[Note: You should assume that the company follows the example set of Architecture Principles provided in the TOGAF standard, ADM Techniques, Architecture Principles chapter.]

A) Service orientation will speed up the merger and make it easier to integratesystems while maintaining business operations. Maximize Benefit to theEnterprise will make sure that merger decisions prioritize the overall benefit tothe combined company. Common Use Applications across the mergedcompany is preferred over the use of similar or duplicative applications forcertain parts of the company. This help supports the goal of merging back-office systems to reduce duplication.
B) Compliance with the Law makes sure that all company activities comply withrelevant laws and regulations. This principle provides the foundation forensuring the merger meets all legal requirements. Requirements-BasedChange will make sure that when combining systems, changes to applicationsand technology are only made if required by business needs. ResponsiveChange Management focuses on the speed needed to achieve the goals setby the leaders for a quick merger. We are committed to quickly blending thecompanies as planned.
C) Control Technical Diversity will help by standardizing technology platforms aspart of the integration process. This will be vital for standardizing the appintegration for digital orders with the back-office systems, and will reducecomplexity and costs during integration. Data Trustee will establish owners tomanage the shared data across the company, thereby assuring data quality.Ease-of-Use is needed to make sure that new user interfaces for the appscontinue to be easy to use.
D) Primacy of Principles will make sure that the same principles apply to bothorganizations of the newly merged operation, creating consistency acrosslocations. Data as an Asset is critical. Since you're maintaining separate mobileapps but consolidating back-end systems, treating data as an asset becomesessential. This principle helps ensure that customer data, and inventoryinformation from both brands are properly integrated and managed.Technology Independence is important when consolidating the back-officeapplications and order processing systems.

3. 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?

A) Conduct an analysis of stakeholders, documenting their concerns and recording them in the Architecture Vision document. Risks should be recorded in the Architecture Requirements Specification and reviewed regularly.
B) Identify key stakeholders and develop a Communication Plan that addresses their needs. Ensure the architecture addresses risk management and summarizes features of the architecture.
C) Create an organization map to show the links between different agency parts. Hold a meeting to teach stakeholders to interpret the models. Manage risks as part of Security Architecture development.
D) Separate stakeholders into groups and categorize them. Develop models for each group and verify that their concerns are addressed in Phase G, Implementation Governance.

4. Please read this scenario prior to answering the question
You are employed as an Enterprise Architect working within the Enterprise Architecture (EA) team at an electric vehicle manufacturer. The company focuses on designing, manufacturing, and advancing battery technology for sustainable transportation, while also investing in charging infrastructure, autonomous driving systems, and renewable energy integration.
The company is introducing a major change to its vehicle design over a five-year period. This will be a cross-functional effort between hardware and software teams, delivering significant new features in the vehicles they manufacture. It is planned to be developed in phases. An architecture to support strategy has been completed with a roadmap for a set of projects.
The EA team has taken over the architecture for the hardware and software automotive platform used by current vehicles, some of which will be used again in the new vehicle design. The EA team has started to pick which parts of the architecture to use again.
The presentation and access to different variations of data that the company plans to offer through its vehicles creates a design challenge. The application portfolio and supporting infrastructure must connect with multiple cloud services and data repositories in different countries to be able to handle the data at a large scale.
Enough of the Business Architecture has been defined, so that work can commence on the Information Systems and Technology Architectures. Those architectures need to be defined to support the primary business services that the company plans to provide. These services will handle and use the data created by vehicles, preparing the way for self-driving vehicles in the future.
The company uses the TOGAF standard as the basis for its Enterprise Architecture framework. The EA team reports to the Chief Technical Officer (CTO), who is the sponsor of the EA program. The CTO requires that the EA team follow the purpose- based EA Capability model as described in the TOGAF Series Guide: A Practitioners' Approach to Developing Enterprise Architecture Following the TOGAF ADM.
Refer to the scenario
How would you plan, organize, and manage the architecture development at this stage?
Based on the TOGAF standard which of the following is the best answer?

A) Architecture descriptions for the Application, Data, and TechnologyArchitectures should be developed at a suitable level to address the problems,and to identify the different options. For each project this includes identificationof candidate architecture and solution building blocks. Solution providersshould be identified, a readiness assessment performed, and an assessmentof the viability and fitness of the solution options. The results should be addedto the draft Implementation and Migration plan.
B) The superior architecture should be used to guide the approach. Review theidentified projects, dependencies, and potential overlaps, then decide the orderfor starting the projects. Develop high-level architecture descriptions. For eachproject determine how much work is needed, identify reference architectures,and candidate building blocks. Identify the resource needs, considering costand value. Document the different options, risks, and ways to control them toenable feasibility analysis and trade-off with the stakeholders.
C) Follow a standard pattern for cloud solutions that manage complex data, andwhich fits with the architecture to support strategy. Develop high-level TargetData, Application and Technology Architectures. Review the Architecture Visionto determine the level of detail, time, and scope of the ADM cycle phasesrequired for architecture development for the project. Identify and estimate thecost of the main work packages. Create an Architecture Roadmap and requestthe Architecture Board to approve the roadmap. Start the project.
D) Start an iteration of ADM Phase A, perform a Stakeholder Analysis, identifyingthe key stakeholders and revising the Architecture Vision. Update theStakeholder map created for the strategic architecture, so it reflects thestakeholders who are now the most important for the projects that are to bedeveloped. Hold a formal review with the CTO, who should decide whichprojects to include in the Architecture Roadmap and update the Implementationand Migration Plan to reflect the decisions.
