Question No. 1

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?

AYou would determine business continuity requirements, and undertake a gap analysis of the current Enterprise Architecture. You would make recommendations for change requirements to address the situation and create a change request. You would manage a meeting of the Architecture Board to assess and approve the change request. Once approved you would produce a new Request for Architecture Work to activate an ADM cycle to carry out a project to define the change.

BYou would monitor for technology changes from your existing suppliers that could improve resilience. 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.

CYou 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.

DYou would request an Architecture Compliance Review with the scope to examine the company's resilience 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.

Show Answer

Correct Answer: A

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.

Question No. 2

Please read this scenario prior to answering the question

You are the Chief Enterprise Architect at a large food service company specializing in sales to trade and

wholesale, for example, restaurants and other food retailers.

One of your company's competitors has launched a revolutionary product range and is running a very

aggressive marketing campaign. Your company's resellers are successively announcing that they are not

interested in your company's products and will sell your competitor's.

The CEO has stated there must be significant change to address the situation. He has made it clear that

new markets must be found for the company's products, and that the business needs to pivot, and address the retail market as well as the existing wholesale market.

A consideration is the company's ability and willingness to change its business model, and if it is a temporary or permanent change. An additional risk factor is one of culture. The company has been used to a stable business with a reasonably well known and settled client base - all with its own local understandings and practices.

The CEO is the sponsor of the EA program within the company. You have been engaged with the sales,

logistics, production, and marketing teams, enabling the architecture activity to start. An Architecture Vision, Architecture Principles, and Requirements have all been agreed. As you move forward to develop a possible Target Architecture you have identified that some of the key stakeholders' preferences are incompatible. The incompatibilities are focused primarily on time-to-market, cost savings, and the need to bring out a fully featured product range, but there are additional factors.

Refer to the scenario

You have been asked how you will address the incompatibilities between key stakeholder preferences.

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

AYou would seek to understand value preferences and priorities of the stakeholders. You would
develop alternative Target Architectures, highlighting the gaps between current state and the
alternatives. You would consider combining features from one or more alternatives in collaboration
with the stakeholders. A formal stakeholder review should then be held to decide which alternative is
fit for purpose and should be moved forward with. You will then secure the funding required.

BYou recommend that since the CEO has stated that the company must pivot, it is better to
compromise on a full product range rather than time-to-market. You would develop just enough of the
Target Architecture to demonstrate fitness of the proposed approach. You would limit the description
to just where there is a gap between the current baseline. You would seek approval by the
stakeholders to move forward with developing the Target Architecture in detail.

CYou would use the Architecture Vision, Principles, and Requirements to define a set of criteria for
alternatives and create a set of architecture views to illustrate the impact of the alternative Target
Architectures. You would identify the impact on planned projects. You would understand the strengths
and weaknesses of the alternatives. You would conduct a formal stakeholder review to decide which
alternative to move forward with. You will determine the funding required.

DYou would review the Stakeholder Map and ensure that you have addressed and represented the
concerns of all department heads. You will involve them in resolving the incompatibilities. The
Communications Plan should include a report that summarizes the key features of the architecture
with and how incompatibilities were resolved to reflects the stakeholders' requirements. You will
check with each key stakeholder they are satisfied with how the incompatibilities have been resolved.

Show Answer

Correct Answer: C

According to the TOGAF standard, the Target Architecture is the description of a future state of the architecture being developed for an organization. It should be aligned with the Architecture Vision, Principles, and Requirements that have been agreed with the stakeholders. To address the incompatibilities between key stakeholder preferences, the TOGAF standard recommends creating and evaluating multiple alternative Target Architectures that meet different sets of criteria. These criteria should reflect the value preferences and priorities of the stakeholders, as well as the business drivers and objectives. The alternative Target Architectures should be illustrated using a set of architecture views that show the impact of each alternative on the business, data, application, and technology domains. The impact on planned projects should also be identified and analyzed. The strengths and weaknesses of each alternative should be understood and documented. A formal stakeholder review should then be conducted to decide which alternative is the most fit for purpose and should be moved forward with. The funding required for implementing the chosen alternative should also be determined and secured.Reference:

Question No. 3

Please read this scenario prior to answering the question

You have been appointed as senior architect working for an autonomous driving technology development company. The mission of the company is to build an industry leading unified technology and software platform to support connected cars and autonomous driving.

The company uses the TOGAF Standard as the basis for its Enterprise Architecture (EA) framework. Architecture development within the company follows the purpose-based EA Capability model as described in the TOGAF Series Guide: A Practitioners'Approach to Developing Enterprise Architecture Following the TOGAF ADM.

An architecture to support strategy has been completed defining a long-range Target Architecture with a roadmap spanning five years. This has identified the need for a portfolio of projects over the next two years. The portfolio includes development of travel assistance systems using swarm data from vehicles on the road.

The current phase of architecture development is focused on the Business Architecture which needs to support the core travel assistance services that the company plans to provide. The core services will manage and process the swarm data generated by vehicles, paving the way for autonomous driving in the future.

The presentation and access to different variations of data that the company plans to offer through its platform poses an architecture challenge. The application portfolio needs to interact securely with various third-party cloud services, and V2X (Vehicle-to-Everything) service providers in many countries to be able to manage the data at scale. The security of V2X is a key concern for the stakeholders. Regulators have stated that the user's privacy be always protected, for example, so that the drivers' journey cannot be tracked or reconstructed by compiling data sent or received by the car.

Refer to the scenario

You have been asked to describe the risk and security considerations you would include in the current phase of the architecture development?

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

AYou will focus on the relationship with the third parties required for the travel assistance systems and define a trust framework. This will describe the relationship with each party. Digital certificates are a key part of the framework and will be used to create trust between parties. You will monitor legal and regulatory changes across all the countries to keep the trust framework in compliance.

BYou will perform a qualitative risk assessment for the data assets exchanged with partners. This will deliver a set of priorities, high to medium to low, based on identified threats, the likelihood of occurrence, and the impact if it did occur. Using the priorities, you would then develop a Business Risk Model which will detail the risk strategy including classifications to determine what mitigation is enough.

CYou will focus on data quality as it is a key factor in risk management. You will identify the datasets that need to be safeguarded. For each dataset, you will assign ownership and responsibility for the quality of data needs. 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 certain circumstances.

DYou will create a security domain model so that assets with the same level can be managed under one security policy. Since data is being shared across partners, you will establish a security federation to include them. This would include contractual arrangements, and a definition of the responsibility areas for the data exchanged, as well as security implications. You would undertake a risk assessment determining risks relevant to specific data assets.

Show Answer

Correct Answer: D

A security domain model is a technique that can be used to define the security requirements and policies for the architecture. A security domain is a grouping of assets that share a common level of security and trust. A security policy is a set of rules and procedures that govern the access and protection of the assets within a security domain.A security domain model can help to identify the security domains, the assets within each domain, the security policies for each domain, and the relationships and dependencies between the domains1

Since the data is being shared across partners, a security federation is needed to establish a trust relationship and a common security framework among the different parties. A security federation is a collection of security domains that have agreed to interoperate under a set of shared security policies and standards. A security federation can enable secure data exchange and collaboration across organizational boundaries, while preserving the autonomy and privacy of each party.A security federation requires contractual arrangements, and a definition of the responsibility areas for the data exchanged, as well as security implications2

A risk assessment is a process that identifies, analyzes, and evaluates the risks that may affect the architecture. A risk assessment can help to determine the likelihood and impact of the threats and vulnerabilities that may compromise the security and privacy of the data assets.A risk assessment can also help to prioritize and mitigate the risks, and to monitor and review the risk situation3

Therefore, the best answer is D, because it describes the risk and security considerations that would be included in the current phase of the architecture development, which is focused on the Business Architecture. The answer covers the security domain model, the security federation, and the risk assessment techniques that are relevant to the scenario.

Question No. 4

Please read this scenario prior to answering the question

You are the Lead Enterprise Architect at a major agribusiness company. The company's main

annual 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.

The CEO appreciates the seriousness of the situation and has set out a change in direction

that is effectively a new business for the company. There are opportunities for new products,

and new markets. The company will use the fields for another harvest and will cease to process

third-party lentils. Thus, the target market will change, and the end-products will be different

and more varied. This is a major decision and the CEO has stated a desire to repurpose rather

than replace so as to manage the risks and limit the costs.

The company has a mature Enterprise Architecture practice based in its headquarters and uses

the TOGAF standard as the method and guiding framework. The practice has an established

Architecture Capability, and uses iteration for architecture development. The CIO is the sponsor

of the activity.

The CIO has assigned the Enterprise Architecture team to this activity. At this stage there is no

shared vision, or requirements.

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?

AYou propose that the team focus on architecture definition, with emphasis on defining
the change parameters to support this new business strategy that the CEO has
identified. Once understood, the team will be in the best position to identify the
requirements, drivers, issues, and constraints for the change. You would ensure that the
architecture development addresses non-functional requirements to assure that the
target architecture is robust and secure.

BYou propose that this engagement define the baseline Technology Architecture first in
order to assess the current infrastructure capacity and capability for the company. Then
the focus should be on transition planning and incremental architecture deployment.
This will identify requirements to ensure that the projects are sequenced in an optimal
fashion so as to realize the change.

CYou propose that the priority is to understand and bring structure to the definition of the
change. The team should focus iteration cycles on a baseline first approach to
architecture development, and then transition planning. This will identify what needs to
change in order to transition from the baseline to the target, and can be used to work out
in detail what the shared vision is for the change.

DYou propose that the team focus its iteration cycles on architecture development by
going through the architecture definition phases (B-D) with a baseline first approach.
This will support the change in direction as stated by the CEO. It will ensure that the
change can be defined in a structured manner and address the requirements needed to
realize the change.

Show Answer

Correct Answer: C

Based on the TOGAF standard, this answer is the best approach for architecture development to realize the CEO's change in direction for the company. The reason is as follows:

The scenario describes a major business transformation that requires a clear understanding of the current and future states of the enterprise, as well as the gaps and opportunities for change. Therefore, the priority is to understand and bring structure to the definition of the change, rather than focusing on the implementation details or the technology aspects.

The team should use the TOGAF ADM as the method and guiding framework for architecture development, and adapt it to suit the specific needs and context of the enterprise. The team should also leverage the existing Architecture Capability and the Architecture Repository to reuse and integrate relevant architecture assets and resources.

The team should focus iteration cycles on a baseline first approach to architecture development, which means starting with the definition of the Baseline Architecture in each domain (Business, Data, Application, and Technology), and then defining the Target Architecture in each domain. This will help to identify the current and desired states of the enterprise, and to perform a gap analysis to determine what needs to change in order to achieve the business goals and objectives.

The team should then focus on transition planning, which involves identifying and prioritizing the work packages, projects, and activities that will deliver the change. The team should also create an Architecture Roadmap and an Implementation and Migration Plan that will guide the execution and governance of the change.

The team should use the Architecture Vision phase and the Requirements Management phase to work out in detail what the shared vision is for the change, and to capture and validate the stakeholder requirements and expectations. The team should also use the Architecture Governance framework to ensure the quality, consistency, and compliance of the architecture work.

Question No. 5

Please read this scenario prior to answering the question

Your role is that of a consultant to the Lead Enterprise Architect in a multinational automotive manufacturer.

The company has a corporate strategy that focuses on electrification of its portfolio, and it has invested

heavily in a new shared car platform to use across all its brands. The company has four manufacturing

facilities, one in North America, two in Europe, and one in Asia.

A challenge that the company is facing is to scale up the number of vehicles coming off the production line to meet customer demand, while maintaining quality. There are significant supply chain shortages for electronic components, which are impacting production. In response to this the company has taken on new suppliers and has also taken design and production of the battery pack in-house.

The company has a mature Enterprise Architecture practice. The TOGAF standard is used for developing

the process and systems used to design, manufacture, and test the battery pack. The Chief Information

Officer and the Chief Operating Officer co-sponsor the Enterprise Architecture program.

As part of putting the new battery pack into production, adjustments to the assembly processes need to be made. A pilot project has been completed at a single location. The Chief Engineer, sponsor of the activity, and the Architecture Board have approved the plan for implementation and migration at each plant.

Draft Architecture Contracts have been developed that detail the work needed to implement and deploy the new processes for each location. The company mixes internal teams with a few third-party contractors at the locations. The Chief Engineer has expressed concern that the deployment will not be consistent and of acceptable quality.

Refer to the scenario

The Lead Enterprise Architect has asked you to review the draft Architecture Contracts and recommend the best approach to address the Chief Engineer's concern.

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

AFor changes requested by an internal team, you recommend a memorandum of understanding
between the Architecture Board and the implementation organization. For contracts issued to third-
party contractors, you recommend that it is a fully enforceable legal contract. You recommend that
the Architecture Board reviews all deviations from the Architecture Contract and considers whether to
grant a dispensation to allow the implementation organization to customize the process to meet their
local needs.

BFor changes undertaken by internal teams, you recommend a memorandum of understanding
between the Architecture Board and the implementation organization. If a contract is issued to a
contractor, you recommend that it is a fully enforceable legal contract. If a deviation from the
Architecture Contract is found, you recommend that the Architecture Board grant a dispensation to
allow the implementation organization to customize the process to meet their local needs.

CYou review the contracts ensuring that they address project objectives, effectiveness metrics,
acceptance criteria, and risk management. Third-party contracts must be legally enforceable. You
recommend a schedule of compliance reviews at key points in the implementation process. You
recommend that the Architecture Board reviews all deviations from the Architecture Contract and
considers whether to grant a dispensation to allow the process to be customized for local needs.

DYou recommend that the Architecture Contracts be used to manage the architecture governance
processes across the locations. You recommend deployment of monitoring tools to assess the
performance of each completed battery pack at each location and develop change requirements if
necessary. If a deviation from the contract is detected, the Architecture Board should allow the
Architecture Contract to be modified meet the local needs. In such cases they should issue a new
Request for Architecture Work to implement a modification to the Architecture Definition.

Show Answer

Correct Answer: C

According to the TOGAF Standard, Version 9.2, anArchitecture Contractis a joint agreement between development partners and sponsors on the deliverables, quality, and fitness-for-purpose of an architecture1.It defines the scope, responsibilities, and governance of the architecture work, and ensures the alignment and compliance of the architecture with the business goals and objectives1.

In the scenario, the Lead Enterprise Architect has asked you to review the draft Architecture Contracts and recommend the best approach to address the Chief Engineer's concern about the consistency and quality of the deployment of the new processes for the battery pack production at each location.

The best answer is C, because it follows the guidelines and best practices for defining and using Architecture Contracts as described in the TOGAF Standard, Version 9.22. It ensures that the contracts cover the essential aspects of the project objectives, effectiveness metrics, acceptance criteria, and risk management, and that they are legally enforceable for third-party contractors. It also recommends a schedule of compliance reviews at key points in the implementation process, and a mechanism for handling any deviations from the Architecture Contract, involving the Architecture Board and the possibility of granting a dispensation to allow the process to be customized for local needs.

The other options are not correct because they either23:

A . For changes requested by an internal team, you recommend a memorandum of understanding between the Architecture Board and the implementation organization. For contracts issued to third-party contractors, you recommend that it is a fully enforceable legal contract. You recommend that the Architecture Board reviews all deviations from the Architecture Contract and considers whether to grant a dispensation to allow the implementation organization to customize the process to meet their local needs.: This option does not address the need to review the contracts to ensure that they address the project objectives, effectiveness metrics, acceptance criteria, and risk management. It also does not recommend a schedule of compliance reviews at key points in the implementation process. Moreover, it suggests that a memorandum of understanding is sufficient for internal teams, which may not be legally binding or enforceable.

B . For changes undertaken by internal teams, you recommend a memorandum of understanding between the Architecture Board and the implementation organization. If a contract is issued to a contractor, you recommend that it is a fully enforceable legal contract. If a deviation from the Architecture Contract is found, you recommend that the Architecture Board grant a dispensation to allow the implementation organization to customize the process to meet their local needs.: This option has the same problems as option A, and also implies that the Architecture Board should always grant a dispensation for any deviation, which may not be appropriate or desirable in some cases.

D . You recommend that the Architecture Contracts be used to manage the architecture governance processes across the locations. You recommend deployment of monitoring tools to assess the performance of each completed battery pack at each location and develop change requirements if necessary. If a deviation from the contract is detected, the Architecture Board should allow the Architecture Contract to be modified meet the local needs. In such cases they should issue a new Request for Architecture Work.: This option does not address the need to review the contracts to ensure that they address the project objectives, effectiveness metrics, acceptance criteria, and risk management. It also does not recommend a schedule of compliance reviews at key points in the implementation process. Moreover, it suggests that the Architecture Board should always allow the Architecture Contract to be modified for any deviation, which may not be appropriate or desirable in some cases. It also implies that a new Request for Architecture Work should be issued for each deviation, which may not be necessary or feasible.
