You have been appointed as Chief Enterprise Architect (CEA). reporting to the Chief Technical Officer (CTO), of a company established as a separate operating entity by a major automotive manufacturer. The mission of the company is to build a new industry leading unified technology and software platform for electric vehicles.
The company uses the TOGAF Standard as the basis for its Enterprise Architecture (EA) framework, and architecture development 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 end-to-end Target Architecture has been completed with a roadmap for change over a five-year period. The new platform will be a cross-functional effort between hardware and software teams, with significant changes over the old platform. It is expected to be developed in several stages over three years. The EA team has inherited the architecture for the previous generation hardware and software automotive platform, some of which can be carried over to the new unified platform. The EA team has started to define the new platform, including defining which parts of the architecture to carry forward.
Enough of the Business Architecture has been defined, so that work can commence on the Information Systems and Technology Architectures. Those need to be defined to support the core business services that the company plans to provide. The core services will feature an innovative approach with 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 pose an architecture challenge. The application portfolio and supporting infrastructure need to interact with various existing cloud services and data-

What component of the Architecture Repository represents architecture requirements agreed with the Architecture Board?
Explanation:
The Architecture Requirements Repository stores all the requirements that are output of the architecture development cycle, as well as the requirements that are input to the architecture development cycle1. The Architecture Requirements Repository includes the following types of requirements1:
* Stakeholder Requirements: These are the high-level requirements and expectations of the stakeholders, derived from the business drivers, goals, and objectives. They are captured and refined in the Architecture Vision phase and the Requirements Management phase.
* Architecture Requirements: These are the detailed requirements that specify what the architecture must do or deliver to meet the stakeholder requirements. They are derived and refined in the Business, Information Systems, and Technology Architecture phases.
* Implementation and Migration Requirements: These are the detailed requirements that specify what the implementation and migration projects must do or deliver to realize the architecture. They are derived and refined in the Opportunities and Solutions and Migration Planning phases.
The Architecture Requirements Repository is used to manage the architecture requirements throughout the architecture lifecycle, ensuring their traceability, consistency, and compliance1. The Architecture Board is the authority that reviews and approves the architecture requirements, as well as the architecture deliverables and artifacts, as part of the architecture governance process2.
Complete the following sentence:
Presenting different_________and_________to stakeholders helps architects to extract hidden agendas principles and requirements that could impact the final Target Architecture
Explanation:
According to the TOGAF Standard, an architecture view is a representation of a system from the perspective of a related set of concerns1.An architecture viewpoint is a specification of the conventions for a particular kind of architecture view1. Presenting different architecture views and architecture viewpoints to stakeholders helps architects to extract hidden agendas, principles, and requirements that could impact the final target architecture.This is because different stakeholders may have different concerns and interests in the system, and by showing them how the system addresses their concerns from different perspectives, the architects can elicit more feedback and validation from them2.For example, a business stakeholder may be interested in the business architecture view, which focuses on the business processes, functions, and capabilities of the system3.A security stakeholder may be interested in the enterprise security view, which addresses the security aspects of the system, such as confidentiality, integrity, and availability3.By presenting these views to the respective stakeholders, the architects can ensure that the system meets their expectations and needs, and also identify any potential issues or gaps that may affect the target architecture.Reference:1: The TOGAF Standard, Version 9.2 - Architectural Artifacts - The Open Group1;2: Understanding TOGAF Views and Viewpoints in Enterprise Architecture2;3: Developing Architecture Views - The Open Group4
Which of the following are the four purposes that typically frame the planning horizon, depth and breadth of an Architecture Project, and the contents of the EA Repository-?
Explanation:
Strategy Portfolio Project Solution Delivery are the four purposes that typically frame the planning horizon, depth and breadth of an Architecture Project, and the contents of the EA Repository. They correspond to different levels of abstraction and granularity in the architecture development process.

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.

You are working as the Chief Enterprise Architect within a law firm specializing in personal injury cases. Many of the firm's competitors have improved their litigation strategies, and efficiency by streamlining their processes using Artificial Intelligence {Al).
The CIO has approved a Request for Architecture Work to examine the use of Machine Learning in defining a new Al-driven litigation and finance process for the firm. This process would instruct the lawyers and analysts as to what tasks and portfolio they should work on. The key objectives are to increase task profitability, maximize staff utilization, and increase individual profitability.
The CIO has emphasized that the architecture should enable the fast implementation of continuous Machine Learning. The solution will need to be constantly measured for delivered value and be quickly iterated to success.
Some of the partners have expressed concerns about letting the Al make the decisions, others about the risks associated with use of it for the type of service they deliver. The CIO wants to know if these concerns can be addressed, and how risks will be covered by a new architecture enabling Al and Machine Learning.
