B.   Solution Context Diagram/Solution Component Diagram/Solution Application Use-Case Diagram/Solution Value Flow Diagram.

Explanation:

SAP provides several artifacts as part of the SAP Reference Solution Architecture content to guide and streamline solution design and implementation. The artifacts provided are aimed at delivering comprehensive architectural documentation to cover various aspects of the solution architecture. Option B includes the Solution Context Diagram, which provides a high-level view of the system's environment and boundaries. The Solution Component Diagram gives an overview of the components and their interactions within the system. The Solution Application Use-Case Diagram describes how different users will interact with the application. The Solution Value Flow Diagram illustrates the value that flows through the system and between stakeholders.

A.   Use "Developer Extensibility for data-intensive ABAP extensions to S/4HANA./Use "Side-by-Side Extensibility on SAP BTP ABAP Environment" when additional SAP BTP services are intensively used and SAPUI5 user interfaces are required.

Explanation:

The decision for the extension model in S/4HANA should be based on the nature of the extension required. Developer Extensibility (in-app extensibility) is suitable for data-intensive extensions that need to operate within the context of S/4HANA. This is because it allows for direct access to S/4HANA's digital core and leverages the power of the HANA database. It is the recommended approach when the extension requires tight integration with core data and processes, ensuring high performance and data consistency.

On the other hand, Side-by-Side Extensibility on SAP BTP ABAP Environment is recommended when the extensions need to utilize additional SAP BTP services such as advanced analytics, machine learning, IoT services, or when creating new user experiences with SAPUI5. This decouples the extensions from the S/4HANA core, which can be beneficial in terms of flexibility, agility, and reducing the impact on the core system during upgrades.

References= These practices are supported by SAP's extensibility guide for S/4HANA, which explains the two extensibility models and their appropriate use cases. SAP documentation on ABAP Platform extensibility options provides further insights into when to choose each extensibility approach. SAP Best Practices for Extensibility in SAP S/4HANA guide provides a comprehensive view on how to extend the digital core effectively while maintaining system integrity and upgradeability.

C.   Application Architect

D.   Business Architect

Explanation:

From the current Enterprise Architecture practice structure presented for Wanderlust GmbH, it appears that there are dedicated roles for a Chief Enterprise Architect and a Technology Architect. However, the roles of Application Architect and Business Architect are not explicitly mentioned. An Application Architect is crucial for designing and maintaining the application landscape, ensuring that it aligns with business requirements, while a Business Architect is essential for aligning IT strategy with business strategy and understanding the impact of business changes on the architecture. Their absence indicates a gap in ensuring the alignment between business processes and IT systems, as well as in defining and maintaining the application strategy.References= The roles and responsibilities within an Enterprise Architecture framework typically include both Application and Business Architects to ensure a comprehensive approach to aligning IT and business strategies.

B.   I evaluate both the SAP EA Methodology and TOGAF ADM. I recommend the approach that fits best Wanderlust's requirements.

D.   I check whether the SAP Reference Business Architecture and Reference Solution Architecture Content can help to either define the scope of the architecture work or describe a target architecture structure. If they do, I suggest to use the Reference Architecture Content of SAP.

Explanation:

When evaluating the SAP Enterprise Architecture Framework for Wanderlust GmbH, you should proceed with the following steps:

I evaluate both the SAP EA Methodology and TOGAF ADM. I recommend the approach that fits best Wanderlust’s requirements. This step is necessary because the SAP EA Methodology is based on TOGAF ADM, but extends it with additional elements and guidance specific to SAP solutions and customers4. Therefore, you need to compare and contrast the two methodologies and assess which one suits Wanderlust’s needs better. For example, you may consider factors such as the complexity, scope, scale, and objectives of Wanderlust’s architecture projects, as well as the availability of resources, skills, and tools.

I check whether the SAP Reference Business Architecture and Reference Solution Architecture Content can help to either define the scope of the architecture work or describe a target architecture structure. If they do, I suggest to use the Reference Architecture Content of SAP. This step is beneficial because the SAP Reference Business Architecture and Reference Solution Architecture Content provide a set of pre-defined architectures that cover common business scenarios and solution domains for SAP customers5. Therefore, you can use them as a starting point or a reference point for your architecture work, as they can help you to define the scope, requirements, capabilities, components, patterns, and best practices for your architecture solutions.

B.   Create a stakeholder map.

Explanation:

In order to rejuvenate the online marketing efforts with a set of employees and partners, creating a stakeholder map is the appropriate next step. A stakeholder map will help to identify and categorize all the relevant parties involved in the online marketing ecosystem, including internal and external stakeholders, their interests, influence, and the relationships between them. This artifact provides a visual representation of all stakeholders, their expectations, and requirements, which is critical for developing a targeted strategy for rejuvenation.

References= Stakeholder mapping is a common practice in enterprise architecture to ensure that all parties affected by a project are identified and their needs are considered in the decision-making process.

A.   Programming language and buildpacks

In the SAP BTP Cloud Foundry environment, several factors are critical during runtime to ensure optimal application performance and scalability. The correct answer, A, highlights two fundamental aspects:

Programming language:This determines the specific buildpack to be used, as Cloud Foundry supports multiple programming languages through different buildpacks which provide framework and runtime support for applications.

Buildpacks:These are key components in the Cloud Foundry architecture that provide runtime and framework support necessary to build and deploy applications in various programming languages effectively.

These elements are crucial as they directly impact how applications are built, deployed, and run within the Cloud Foundry environment, influencing performance, compatibility, and scalability.

B.   If the data objects are built with data from different SAP and non-SAP sources that can be structured and unstructured, change with high frequency, and need to be cleansed, correlated and partly newly calculated.

Explanation:

A data-oriented integration approach is optimal when dealing with diverse data sources and complex data requirements. This includes scenarios where the data is both structured and unstructured, changes rapidly, and needs significant processing such as cleansing, correlation, and partial recalculation. The advantage of this approach is that it centralizes data handling and transformation logic, allowing for more efficient data processing and integration into a central store like SAP HANA Cloud.

References= SAP's guidelines on data integration recommend this approach when handling large and complex data sets that require intensive processing and are sourced from a variety of SAP and non-SAP systems. It is supported by SAP's data management and integration tools that are designed to handle such complexity and frequency of change.

C.   Business Capability Model/Business Process Model

A.   Conduct a Fit Gap Assessment to identify requirements that cannot be met

B.   Define the Solution Context for the architecture work.

E.   Outline the aspirational Solution Concept to address the stakeholders' needs and business requirements.

Explanation:

The Statement of Architecture Work should encompass a Fit Gap Assessment to understand what requirements are currently not met by existing capabilities, the definition of the Solution Context to set the boundaries and scope of the architecture project, and the outline of the aspirational Solution Concept thatencapsulates the stakeholders' needs and business requirements. These steps are vital in the preparatory phase to ensure that the architecture work is well-defined and targeted to deliver the anticipated outcomes.

References= These activities are part of standard enterprise architecture practices and are necessary to develop a comprehensive and actionable Statement of Architecture Work that guides the SAP IBP implementation initiative.

B.   I use the SAP Discovery Center to check which of the selected SAP BTP services are offered by which hyperscaler. With help from the SAP Trust Center, I check in which data center the involved SAP SaaS solutions are available.

Explanation:

According to the SAP Discovery Center 1 and the SAP Trust Center 2, the steps involved in this validation are:

Use the SAP Discovery Center to check which of the selected SAP BTP services are offered by which hyperscaler. The SAP Discovery Center is a platform that provides access to SAP BTP services, events, and related resources, and helps you to implement your use cases on SAP BTP with step-by-step guidance and support from topic experts and SAP Community. In the Service Catalog section of the SAP Discovery Center, you can browse and filter the available SAP BTP services by category, region, or hyperscaler. You can also compare the features and pricing of different services, and learn how to use them in your projects.

Use the SAP Trust Center to check in which data center the involved SAP SaaS solutions are available. The SAP Trust Center is a platform that provides information on cloud performance, security, privacy, and compliance. In the Certification and Compliance section of the SAP Trust Center, you can find certificates, reports, and attestations that show how SAP meets various industry standards and regulatory requirements. You can also filter the documents by solution, region, or hyperscaler, and download them for your reference.

The other options (A and C) are not correct for how to validate the availability of SAP BTP services and SAP SaaS solutions in the desired hyperscaler’s data center, because they either do not exist or do not provide the required information. For example:

Option A is not correct because there is no such platform as SAP Business Accelerator Hub (api.sap.com) that provides all the required information regarding SAP BTP service and SAP SaaS solution availability for each hyperscaler. The correct name of the platform is SAP API Business Hub (api.sap.com), which is a platform that provides access to SAP APIs, events, and related resources, but it does not provide any information on the availability of SAP BTP services or SAP SaaS solutions for each hyperscaler or data center.

Option C is not correct because the SAP Discovery Center does not provide any information on the availability of SAP SaaS solutions for each hyperscaler or data center. The SAP Discovery Center only provides information on the availability of SAP BTP services for each hyperscaler or region, but not for specific data centers. To check the availability of SAP SaaS solutions for each data center, you need to use the SAP Trust Center instead.

C.   SAPUI5 (SAP Fiori) applications

Explanation:

SAP Business Application Studio is a modern development environment designed to support the development of various SAP-centric applications. Among the supported application types are:

SAPUI5 (SAP Fiori) applications (C):SAP Business Application Studio provides extensive tools and templates specifically tailored for developing SAPUI5 applications, which are the backbone of the SAP Fiori user experience. This includes support for frontend development with rich user interfaces, integration with SAP services, and adherence to SAP Fiori design principles.

Options A and B are incorrect because SAP Business Application Studio does not support ABAP development directly within its environment. ABAP development traditionally requires a different set of tools and environments provided by SAP, such as the ABAP Development Tools (ADT) in Eclipse or the ABAP environment on SAP Cloud Platform.
