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?

Answer options
A:

A. You 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.
B:

B. You 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.
C:

C. You 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.
D:

D. You 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.

 Correct answer
Correct Answer:
D. D. You 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.
Explanation

This answer is the most comprehensive and appropriate for the Business Architecture phase (Phase B) as described in the TOGAF standard. It correctly addresses the scenario's key challenges: managing security across multiple third parties (federation), defining business-level responsibilities (contractual arrangements), and protecting key assets (data). Creating a security domain model provides a structured way to apply policy at a business level. Establishing a security federation is a business-level decision to manage trust and identity with partners. Defining responsibilities and conducting a risk assessment on data assets are all core security activities within the Business Architecture phase, focusing on what needs to be protected and how organizations will interact, rather than on specific technical implementations.

Why Incorrect

A. This option is incorrect because it prematurely focuses on a specific technical solution (digital certificates), which is more appropriate for the Technology Architecture phase (Phase D), not the Business Architecture phase. B. While performing a risk assessment is a valid and necessary activity, this option is less complete than D. It omits the crucial business-level structures (federation, contractual arrangements) needed to manage the complex multi-party environment described in the scenario. C. This option is too narrowly focused on data classification and ownership. While these are important aspects, it fails to address the broader architectural challenge of establishing trust and defining security responsibilities with external V2X and cloud partners.

Phase B: Business Architecture

Section 5.4.2 Security Architecture. This section states that during Phase B

architects should "Identify the trust requirements between the organization and external parties" and "Identify the security policies that will be required". A security federation and contractual arrangements are business-level constructs that define these trust requirements.

which include: "Perform a business-level risk assessment"

"Identify the business assets to be protected"

and defining "trust requirements". These activities directly support the comprehensive approach outlined in option D

which combines risk assessment with the business structures (domains

federation) needed to manage that risk.

discusses identity federation as a process that "allows an organization to trust identity information from another organization". Establishing this trust through federation and contractual agreements is a business-level concern

fitting for Phase B.
