Explanation
According to the SAP Enterprise Architecture Framework, which is a methodology and toolset by the German multinational software company SAP that helps enterprise architects define and implement an architecture strategy for their organizations, the first phase of the architecture development cycle is the architecture vision, which involves defining the scope, objectives, and stakeholders of the architecture project, and creating a high-level vision of the desired outcome. The questions in option C are aligned with this phase, as they aim to understand and assess the business strategy and transformation drivers of Green Elk & Company, and to identify the value proposition, value chain, and business capabilities that are relevant for the new business model. The questions in option C are:
How is the value chain transformed? Which parts of the value chain must be optimized? This question helps to understand how the new business model affects the way Green Elk & Company creates and delivers value to its customers, and which activities or processes need to be improved or changed to support the new business model.
What is the competitive advantage and what are the value potentials that can be realized through the transformation? This question helps to understand what differentiates Green Elk & Company from its competitors, and what benefits or opportunities it can achieve by adopting the new business model.
Which business capabilities will be required or need to mature to support future business models? This question helps to identify the skills, resources, and competencies that Green Elk & Company needs to develop or enhance to enable and sustain the new business model.
The other options (A, B, D) are not correct for the set of questions to ask the owner of the business unit of finished goods, because they either skip or misrepresent some of the aspects of the architecture vision phase.
For example:
Option A is not correct because it focuses too much on the technological aspects of the architecture project, such as technological concepts, integration technology, and partner organization. These aspects are more relevant for later phases of the architecture development cycle, such as application architecture or technology architecture. The questions in option A do not address the business aspects of the architecture project, such as business goals, drivers, constraints, or value proposition.
Option B is not correct because it does not include asking about the value chain or the business capabilities, which are important aspects of the architecture vision phase. The value chain describes how Green Elk & Company creates and delivers value to its customers, and the business capabilities describe what Green Elk & Company can do or needs to do to achieve its goals. The questions in option B only focus on the transformation drivers and the future business model, which are not enough to define a comprehensive architecture vision.
Option D is not correct because it also focuses too much on the technological aspects of the architecture project, such as technological concepts and hyperscaler strategy. These aspects are not relevant for interviewing the owner of the business unit of finished goods, who is more concerned with the business aspects of the architecture project. The questions in option D do not address the value proposition or the value chain, which are essential for understanding how Green Elk & Company creates and delivers value to its customers.

Explanation
The clean-core strategy is a SAP initiative to keep the core of SAP applications as clean as possible by moving customizations and extensions to the side-by-side layer. This allows SAP to more easily deliver new releases of applications without having to worry about breaking custom code.
The following are the benefits of following the clean-core strategy:
Stability: Extensions that are developed in accordance with the clean-core strategy are less likely to break when the underlying application is upgraded.
Maintainability: Extensions that are developed in the side-by-side layer are easier to maintain than extensions that are embedded in the core application.
Flexibility: The clean-core strategy allows for more flexibility in how extensions are developed.
Therefore, the clean-core strategy is a good way to ensure that future extensions to the Digital Core of the enterprise guarantee stable and reliable operations.
The clean-core strategy is a SAP initiative to keep the core of SAP S/4HANA as clean as possible by moving customizations and extensions to the side-by-side layer. This allows SAP to more easily deliver new releases of S/4HANA without having to worry about breaking custom code. The clean-core strategy ensures that extensions do not break an upgrade, and upgrades do not break an extension. This means that extensions are compatible with the latest version of SAP S/4HANA and do not require any changes or adaptations when a new release is applied. To achieve this, extensions must access SAP business objects only through well defined, upgrade-stable interfaces, such as public APIs, OData services, or events. These interfaces are documented and maintained by SAP and guarantee backward compatibility and stability across releases.

Explanation
Starting with the current processes will help to understand the capabilities that are needed in a new application.
This will help to narrow down the field of potential applications and identify those that are most likely to meet the needs of Wanderlust.
Mapping business capabilities to these processes will help to identify the gaps in the current capabilities and the areas where improvement is needed. This will help to ensure that the new application meets the needs of Wanderlust and addresses the issues plaguing the existing application.
Relating Wanderlust processes to industry standard processes will help to identify applications that are already being used by other organizations. This can be a good way to ensure that the new application is compatible with other systems and that it can be easily integrated with existing systems.
The other two options, Comparing the costs of those market leading online marketing applications and Understanding the features of leading online marketing applications available in the market through product demonstrations and ranking the applications in terms of features, are not as critical at this stage. The costs of the applications can be compared once the shortlist of applications has been finalized. The features of the applications can be understood through product demonstrations once the shortlist has been finalized.
Therefore, the best course of action is to start with the current processes, map business capabilities to these processes, and identify which application(s) in the market can deliver such capabilities. This will help to narrow down the field of potential applications and identify those that are most likely to meet the needs of Wanderlust.
Here are some of the benefits of taking a process-centric approach to selecting a new marketing application:
It can help to ensure that the new application meets the needs of the business.
It can help to identify applications that are already being used by other organizations.
It can help to ensure that the new application is compatible with other systems and that it can be easily integrated with existing systems.

Explanation
Identifying the online marketing business capabilities and processes will help to understand the current state of the ecosystem and identify the areas where improvement is needed. For example, if the ecosystem does not have the ability to track leads or manage customer relationships, then these will be areas that need to be addressed.
Identifying the key organizational units, partners, and stakeholder groups that make up the online marketing ecosystem will help to understand the relationships between the different entities in the ecosystem and identify the dependencies between them. For example, if the marketing team relies on the sales team to provide leads, then this dependency will need to be considered when designing the new ecosystem.
The other two options, Identifying a suitable online marketing application that is better integrated with SAP CRM and ECC and can replace the existing one and Drawing an organization map highlighting the inter relationships and hierarchies amongst the above organizational units, partners, and stakeholder groups, are not as critical at this stage. The application can be identified and the organization map can be drawn once the business capabilities and processes have been identified and the key organizational units, partners, and stakeholder groups have been identified.
Therefore, the best course of action is to identify the online marketing business capabilities and processes and identify the key organizational units, partners, and stakeholder groups that make up the online marketing ecosystem. This will help to understand the current state of the ecosystem and identify the areas where improvement is needed.
