Question 1

Please read this scenario prior to answering the question

You are employed as an Enterprise Architect within a multinational company. The company has been very successful and has been buying companies around the world. This has led to a growing number of manufacturing divisions in various locations with a complex supply chain.

The top management recently expressed concerns about the company's effectiveness because of its multiple data centers and duplicate applications. The EA team has been working on a project to solve this issue. An analysis shows that supply chain issues have led to not enough products being produced to meet all the customer demand.

A strategic architecture has been defined to help meet customer demand and manage the supply chain more effectively. The strategic architecture involves combining different Enterprise Resource Planning (ERP) applications that are currently used separately in the company’s production sites.

Each division has finished the Architecture Definition documentation to address their own specific manufacturing needs. The Enterprise Architects have agreed an overall strategy for the migration. They have defined a set of work packages that address the gaps found. They have defined the intermediate architectural states between the Baseline and Target architecture to add a new ERP environment into the company.

Because of the risks posed by this change from the current environment, the architects have recommended that a phased approach should be taken to implement the target architecture with several stages of change. They have created a draft roadmap with the implementation process estimated to take over two years.

The company has an established Enterprise Architecture (EA) practice and follows the TOGAF Architecture Development Method. The company also uses various management frameworks such as business planning, project/portfolio management, and operations management. The EA program is sponsored by the Chief Information Officer (CIO). In your role as an Enterprise Architect within the EA team, you work closely with the important stakeholders from the various divisions within the company.

Refer to the scenario

You have been assigned to plan the next steps for the migration. Which approach will you choose?

Based on the TOGAF standard which of the following is the best answer?

You will focus on project selection. You make sure that the Implementation and Migration plan aligns with the other management frameworks in use in the company. Next, you assign a value to each work package, taking into account the resources available and how they fit into the overall strategy. Using these work packages, you estimate resource requirements and timings. You then select which projects will be included in the Implementation and Migration Plan.
You estimate the business value for each project by applying the Business Value Assessment Technique to prioritize the migration projects and project steps. The assessment should focus on return on investment and criteria for evaluating performance to track the progress of the architecture transformation. You would confirm and plan a series of Transition Architecture phases using a table of Architecture Definition Increments that lists the projects. You then update the Implementation and Migration Plan.
You finalize the Architecture Definition documentation with updates to reflect the implementation approach. You ensure that Implementation and Migration Plan is consistent with the chosen approach. You identify the resources needed to undertake the development projects. You would then produce an Implementation Governance Model to manage the lessons learned before finishing the plan. You ensure that the lessons learned are applied to the Implementation and Migration Plan.
You conduct a series of Compliance Assessments to check that the architecture is being implemented as required by the contract. This is done now to confirm that the implementation team is following the correct development process, and if not, so course correction is viable. This involves using monitoring tools and making sure that performance targets are being achieved. If the targets are not met, you would then need to make adjustments to the performance requirements and update them in the Implementation and Migration Plan.

Question 2

Please read this scenario prior to answering the question

You are employed as an Enterprise Architect within an Enterprise Architecture (EA) team at a global company that sells consumer products.

The company uses the TOGAF standard as the foundation for its Enterprise Architecture framework, and architecture development follows the purpose-based EA Capability model outlined in the TOGAF Series Guide: A Practitioners’ Approach to Developing Enterprise Architecture Following the TOGAF® ADM. The EA team reports to the Chief Information Officer (CIO), who oversees the program.

The company has announced a major change to its products that will occur over a four-year period. This change includes the introduction of digital products and services. An architecture to support strategy has been completed, along with a roadmap for a set of projects to implement this significant change. This will be a cross-functional effort between the product design and software teams. It is planned to be developed in phases.

The company faces a challenge in presenting and providing access to different services through its products and digital platforms, while ensuring compliance with data privacy laws. In some countries and regions, the data residency requirements mean that the company must store certain data within the region where it is collected. As a result, the company’s application portfolio and infrastructure must connect with various cloud services and data repositories in different countries.

The EA team has taken over the architecture used by the current products, some of which can be carried over to the new products. The EA team has started to choose which parts of the architecture to carry over. 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 key digital services that the company plans to provide.

Refer to the scenario

You have been asked how to decide and organize the work to deliver the requested architectures?

Based on the TOGAF standard which of the following is the best answer?

The architecture to support strategy should be used to guide the approach. Review the identified projects, dependencies, and overlaps, then decide the order for starting the projects. Develop high-level architecture descriptions. For each project determine how much work is needed, identify reference architectures, and candidate building blocks. Identify the resource needs, considering cost and value. Document the different options, risks, and ways to control them to enable feasibility analysis and trade-off with the stakeholders.
Architecture descriptions for the Application, Data, and Technology Architectures should be developed at a suitable level to address the problems, and to identify the different options. For each project this includes identification of candidate architecture and solution building blocks. Solution providers should be identified, a readiness assessment performed, and an assessment of the viability and fitness of the solution options. The results should be added to the draft Implementation and Migration plan.
Follow a standard pattern for cloud solutions that manage complex data and that fits with the architecture to support strategy. Develop high-level Target Data, Application and Technology Architectures. Review the Architecture Vision to determine the level of detail, time, and scope of the ADM cycle phases required for architecture development for the project. Identify and estimate the cost of the main work packages. Create an Architecture Roadmap and request the Architecture Board to approve the roadmap. Start the project.
Start an iteration of ADM Phase A, perform a Stakeholder Analysis, identifying the key stakeholders and revising the Architecture Vision. Update the Stakeholder map created for the strategic architecture, so it reflects the stakeholders who are now the most important for the projects that are to be developed. Hold a formal review with the CTO, who should decide which projects to include in the Architecture Roadmap and update the Implementation and Migration Plan to reflect the decisions.

Select an answer above, then submit your vote. Reading or practicing does not cast a vote.

Question 3

Please read this scenario prior to answering the question

You are employed as an Enterprise Architect for a company that is an international supplier of manufacturing systems.

The company has multiple manufacturing plants where it assembles both standard and customized products for industrial production automation. Each of these plants has been operating its own planning and production scheduling systems, as well as applications and control systems that drive the automated production line. The current systems work with the local partners in the supply chain at each plant.

The company has been facing competition in the marketplace and its leadership has been considering how to improve production efficiency. A favored proposal is to replace many of the systems with a centralized system communicating with the manufacturing plants. The CIO has asked the EA team to develop an architecture for this approach that supports both standardized and customized production across multiple manufacturing plants, while maintaining enterprise-wide integration and governance.

The company has an Enterprise Architecture (EA) practice and uses the TOGAF standard as the basis for its work. It has been running for many years and has established governance and development processes for EA. The Chief Information Officer (CIO) sponsors the Enterprise Architecture program. You are part of an Enterprise Architecture (EA) team that has responsibilities across the company.

As a supplier of manufacturing systems with multiple plants, there are many interested parties that will need to be satisfied.

The Architecture Board has approved the Request for Architecture Work to find out if such an architecture transformation would lead to efficiency improvements.

Refer to the scenario

You have been assigned to lead this project and asked to outline your next steps.

Based on the TOGAF standard, which of the following is the best answer?

You would run multiple workshops at the manufacturing plants to discover and document business requirements. This would also help you understand the location-specific problems and identify the actors and roles at each location. You would create a matrix of stakeholders to identify key people involved and their concerns. You would then determine and record the main stakeholder requirements for the architecture. Finally, you would create clear high-level descriptions of the current and future architectures.
You would conduct a series of workshops with the local partners to gather requirements from them. Based on the findings from the workshops, you would define a preliminary Architecture Vision including summary views, high-level requirements, and high-level definitions of the baseline and target environments from a business, information systems, and technology perspective. You would then use the Architecture Vision to build agreement among the local partners.
You would create high level views of the baseline and target Architectures for each manufacturing plant, and then a set of views corresponding to selected viewpoints to address key concerns of the stakeholders. The gap analysis results for the architectures should be reviewed and consolidated into a single list. A set of work packages should be identified. A formal stakeholder review should be held to obtain approval before moving to the Target Architecture phase.
You would run a proof-of-concept project to allow your suppliers to demonstrate candidate off-the-shelf solutions that address the concerns of the stakeholders. After looking at the results of the project, you would select the most efficient solution and use that to set the requirements. Once the requirements are complete, there should be a formal stakeholder review, and permission requested to move forward to develop the Target Architecture.

Question 4

Please read this scenario prior to answering the question

You are employed as an Enterprise Architect working within an Enterprise Architecture (EA) team at a car manufacturing company. Enterprise Architecture (EA) provides the company with a comprehensive framework to develop and manage their manufacturing infrastructure, processes for component production, and design and testing systems.

The company is moving ahead with switching to electric power for its vehicles. The shift from combustion engines to electric motors marks a fundamental transformation for the company. As a result, the company has invested heavily in a new standardized design, production efforts, and components to use across all its brands.

A challenge that the company is facing is to maintain quality while increasing the number of vehicles coming off the production line to meet customer demand. Significant supply chain shortages for some components are impacting production. In response to this the company has taken design and production of the battery pack in-house and contracted new suppliers.

You are working on a project to improve the manufacturing process and systems to design, produce, and test the battery pack. As part of putting the new battery pack into production, changes to the assembly processes need to be made. A successful trial has been completed at a single location. The Chief Engineer, sponsor of the project, and the Architecture Board have approved the plan to roll out these changes to each of the manufacturing plants.

The EA team leader has called a meeting. He notes that the Architecture Contract will serve as the key connection between architecture and implementation organizations. Preliminary Architecture Contracts are being developed to detail the work needed to put in place the new processes for each location. The company mixes internal teams with a few third-party contractors at the locations. The Chief Engineer is worried that the implementation and deployment will not be consistent and of satisfactory quality across all the locations.

The company uses the TOGAF standard as the foundation for its work, including the company's internal Enterprise Architecture framework. Also, the company uses different management frameworks including business planning, project management, and operations management. The company has factories in North America, Europe, and Asia. The EA team is responsible for all the manufacturing plants.

Refer to the scenario

The EA team leader has asked you for the best way to address the Chief Engineer's concern.

Based on the TOGAF standard, which of the following is the best answer?

The contracts must specify goals, measures, acceptance terms, and risks. Third-party contracts need to be legally enforceable. There needs to be a schedule of compliance reviews at key points in the implementation process. The Architecture Board must review all deviations from the Architecture Contract. The Architecture Board must consider whether to grant a dispensation to allow the process to be customized for local needs. Establish a dispute resolution mechanism for issues not resolved through the compliance and dispensation processes.
The contracts must be checked to ensure they can direct and control the implementation teams. There must be a memorandum of understanding between the Architecture Board and the implementation organization for project work undertaken by an internal team. There must be fully enforceable legal contracts for any contracts issued to third-party contractors. The Architecture Board must review all deviations from the Architecture Contract and decide if to grant a dispensation to allow the implementation organization to customize the process to meet their local needs.
The contracts must be checked to ensure they have flexibility. There must be a legal contract in place for all changes assigned to be made by contractors. There must be a memorandum of understanding between the Architecture Board and the implementation organization for changes made by internal teams. If the implementation organization needs to customize the process to meet their local needs, the Architecture Board will grant a dispensation to allow deviation from the contract.
The contracts must be used to manage the architecture governance processes across the locations. Monitoring tools will be used to assess the performance of each completed battery pack at each location and used to identify the change requirements if necessary. If a deviation from the contract is needed to meet local needs, the Architecture Board should allow the Architecture Contract to be modified. In such cases the Architecture Board must issue a new Request for Architecture Work to implement a modification to the Architecture Definition.

Question 5

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. The goal of the company is to build the best technology and software platform to support self-driving cars.

An architecture to support strategy has been completed defining a long-term Target Architecture with a roadmap over five years. This has identified the need for a portfolio of projects over the next two years. The portfolio includes development of an advanced driver assistance system using data gathered from multiple vehicles on the road.

The design of the presentation and accessibility of different types of data that the company plans to offer through its platform is challenging. It is important for the application portfolio to work securely with third-party cloud services, and V2X (Vehicle-to-Everything) service providers across many countries in order to effectively manage large amounts of data. Stakeholders are particularly concerned about the security of V2X. Regulations in various markets mandate that user privacy must always be safeguarded, to prevent tracking and compiling of data that could reveal the drivers' journey.

The company follows the TOGAF standard as the basis for its Enterprise Architecture practice and uses the purpose-based EA Capability model as described in the TOGAF Series Guide: A Practitioners’ Approach to Developing Enterprise Architecture Following the TOGAF® ADM. The EA team reports to the Chief Information Officer (CIO), who is the sponsor of the EA program.

You have been assigned to lead the architecture development effort for the driver assistance system. A security resource plan and a vision for a security-specific architecture design have been completed. You have a meeting with the EA team leader to talk about the progress of your work.

Refer to the scenario

You have been asked how you will address risk and security at this stage of the architecture project.

Based on the TOGAF standard which of the following is the best answer?

Since data is being shared across multiple service providers, a security federation should be established. This includes contractual arrangements, and a definition of the responsibility areas for the data exchanged, as well as security implications. Assets with the same security criteria should be grouped together so they can be managed under one security policy. A risk assessment should be carried out to determine the risks relevant to specific data assets.
A qualitative risk assessment should be carried out for the data assets exchanged with the service providers. This will deliver a set of priorities, high to medium to low, based on identified threats, the likelihood of occurrence, and the impact. Using the priorities, a Business Risk Model can then be developed detailing the risk strategy including classifications to determine what mitigation is sufficient. This model can then used to determine the risk strategy for the company.
A trust framework should be established with the third parties required for the travel assistance systems. This will describe the relationship with each party and establish the foundation for secure cloud operations. Digital certificates should be a key part of the framework and will be used to create trust between the parties. Regular monitoring for legal and regulatory changes across all the countries should occur to keep the trust framework in compliance.
Data quality is a key factor in risk management. The datasets that need to be safeguarded should be identified. For each dataset, ownership and responsibility for the quality of data should be assigned. A security classification will be defined and applied to each dataset. The dataset owner will then be able to authorize processes that are trusted for a certain activity on the dataset under specific circumstances.

Question 6

Please read this scenario prior to answering the question

You are employed as an Enterprise Architect at a large company. The company runs an online platform that connects buyers and sellers in one place. It also runs a large number of retail stores.

The retail stores serve as local fulfillment hubs for online orders, enabling faster delivery and reducing shipping costs. When a customer places an order, the system checks for nearby stores that have the item in stock. If available, the store prepares the order for same-day pickup, or local courier delivery.

Each retail store follows the same method to track sales and inventory. They send accurate timely sales data to a central inventory management system that uses AI (Artificial Intelligence) to forecast 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 retail 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 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 and has been engaged for this project. The company has an Architecture Board with representatives from different parts of the business. The EA program is sponsored by the Chief Information Officer (CIO).

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. The next step is to revisit and review the Architecture Principles, as they form part of the constraints on architecture work.

Business Continuity is an essential principle given that the business depends on real-time ordering and automated inventory management.

Refer to the Scenario

In addition to Business Continuity, which Architecture Principles do you consider most relevant for guiding the transformation?

Based on the TOGAF standard, which of the following is the best answer?

[Note: The sequence of the principles listed in each answer does not matter. You should assume the company follows the example set of principles that are provided in the TOGAF standard, ADM Techniques, Architecture Principles chapter.]

Common Use Applications, Data is an Asset, Data is Accessible, Ease of Use
Control Technical Diversity, Interoperability, Data Trustee, Data is Shared
Maximize Benefit to the Enterprise, Common Use Applications, Responsive Change Management, Technology Independence
Common Vocabulary and Data Definitions, Compliance with the Law, Requirements Based Change, Data Security
