C_CPI_2506 SAP Certified Associate - Integration Developer Questions and Answers

For an asynchronous integration architecture, the best design pattern is Event-Driven Architecture (EDA):

Events (notifications) are published by producers and consumed by interested partners asynchronously.

Enables decoupled, scalable, and resilient communication.

Other options:

Serverless design → A runtime execution model, not a messaging pattern.

Request-driven design → Synchronous, not asynchronous.

Hexagonal design → A software architecture pattern, not messaging-driven.

Thus, for exchanging asynchronous notifications between partners, the correct design is Event-driven design.

In XSLT mapping:

→ Matches each node (any element node) in the XML source.

→ Matches only the root node.

→ Matches all attributes of the current element.

→ Matches text nodes only.

Thus, to select each node, the correct statement is .

In SAP Cloud Integration (part of Integration Suite), the Data Store operations allow temporary or persistent storage of messages for asynchronous processing or correlation.

WRITE → Used to save/store data (e.g., Customer ID) in the Data Store.

GET → Retrieves stored data.

SELECT → Reads stored data with filters.

POST → Not a valid Data Store operation in SAP CPI (it’s an HTTP verb).

Hence, to save a customer ID, the correct operation is WRITE.

OData (Open Data Protocol) is a REST-based protocol standardized by OASIS and adopted widely in SAP systems.

It builds on HTTP as the communication protocol.

It uses AtomPub (Atom Publishing Protocol) and JSON as payload representation formats.

SOAP is not used for OData; instead, OData relies on REST principles.

TCP is the underlying transport layer, but OData is explicitly defined over HTTP.

Thus, the correct basis for OData is HTTP, AtomPub, and JSON.

In SAP systems (e.g., S/4HANA, SAP Gateway), OData services follow a standard URL path:

/sap/opu/odata → The valid and official prefix for OData services.

Example: /sap/opu/odata/sap/API_BUSINESS_PARTNER

Other options:

/sap/opo/odata and /sap/odu/odata → Typographical variations, not valid.

/soap/opu/odata → Incorrect, since OData is not SOAP-based.

Thus, the valid prefix is /sap/opu/odata.

SAP Integration Suite, Advanced Event Mesh (formerly SAP Event Mesh) is designed to facilitate asynchronous communication in distributed systems, primarily supporting the Event-Driven Architecture (EDA) pattern. This architectural pattern enables systems to produce, detect, consume, and react to events in real time, allowing loosely coupled, scalable, and resilient integration across applications and services.

Why Option C is Correct:

Event-Driven Architecture (EDA) in SAP Advanced Event Mesh: SAP Integration Suite, Advanced Event Mesh is a cloud-based messaging service that enables event-driven communication by allowing applications to publish and subscribe to events asynchronously. It supports real-time event streaming and processing, which aligns with the core principles of EDA. In EDA, events are generated when something of interest occurs (e.g., a state change in a business process), and other systems or services react to these events without direct coupling.

SAP Reference: According to the SAP Integration Suite Documentation and SAP Advanced Event Mesh Developer Guide, Advanced Event Mesh is explicitly designed to support event-driven architectures. It provides features like event brokers, topic-based routing, and guaranteed message delivery, which are hallmarks of EDA. The service enables scenarios such as real-time data integration, IoT event processing, and cross-application event notifications in SAP and non-SAP environments.

Practical Usage: In SAP Integration Suite, Advanced Event Mesh is used to implement EDA by allowing integration flows (iFlows) to publish events to topics or subscribe to events from other systems. For example, an SAP S/4HANA system can publish an event (e.g., "Order Created") to Advanced Event Mesh, which other systems (e.g., a logistics application) can consume and process asynchronously.

Why Other Options are Incorrect:

A. Publish-Subscribe pattern: While Advanced Event Mesh uses the publish-subscribe mechanism as a messaging pattern (where publishers send messages to topics and subscribers receive them), this is a lower-level messaging pattern, not an architectural pattern. EDA encompasses publish-subscribe as one of its implementation mechanisms, but EDA is the broader architectural pattern that defines the system’s behavior and design. Thus, EDA is the more accurate answer for the architectural context.

B. Microservices Architecture pattern: Microservices Architecture is a design approach where applications are built as independent, loosely coupled services. While Advanced Event Mesh can be used in microservices-based systems to enable asynchronous communication, it is not the primary architectural pattern it supports. Instead, it supports EDA, which can be applied within microservices or other architectures.

D. Message Queue pattern: The Message Queue pattern involves point-to-point messaging where messages are sent to a specific queue and consumed by a single recipient. While Advanced Event Mesh supports queue-based messaging, its primary focus is on event-driven, topic-based communication, which is more aligned with EDA. Message queues are a subset of the capabilities provided by Advanced Event Mesh, but they do not represent the overarching architectural pattern.

SAP Integration Developer Workflow Example:

Configure Event Mesh: In SAP Integration Suite, an Integration Developer configures Advanced Event Mesh by creating an event broker and defining topics or queues (e.g., sap.s4.order.created).

Publish Events: An SAP system or external application publishes events to the topic using protocols like MQTT, AMQP, or REST.

Subscribe to Events: Integration flows or external applications subscribe to the topic to consume events and trigger actions, such as updating a database or notifying another system.

EDA Implementation: This setup enables decoupled, scalable communication, where multiple consumers can react to the same event without direct dependencies, embodying the EDA pattern.

When generating a Service Key for an SAP Integration Suite Event Mesh message client, the credentials contain details required for authentication and connection.

Event Mesh uses OAuth 2.0 client credential flow for secure access.

The Service Key includes:

Client ID

Client Secret

OAuth Token URL

These values are used by applications to authenticate and obtain tokens before accessing Event Mesh queues or topics.

Other methods (Basic Authentication, API Keys, X.509 certificates) are not used by default for Event Mesh service keys.

REST (Representational State Transfer) is:

An architectural style for designing networked applications.

Based on principles such as statelessness, resource orientation, uniform interface (HTTP methods: GET, POST, PUT, DELETE).

Used widely in SAP (OData is REST-based).

Other options:

Not a protocol (like HTTP), not a description language (like OpenAPI), and not limited to messaging.

Correct definition → Architectural style.

SAP Integration Suite, Advanced Event Mesh (AEM) is the SAP offering that provides a highly scalable, distributed event streaming platform. It is specifically designed for large-scale, hybrid, and multi-cloud landscapes where event-driven communication is required across diverse applications and systems.

Key points from SAP documentation:

Protocol Support: Advanced Event Mesh supports MQTT, AMQP, JMS, REST, and WebSocket protocols, ensuring secure and efficient event transmission across heterogeneous IT landscapes.

Scalability and Distribution: Unlike standard SAP Event Mesh, which is intended for simpler messaging scenarios, AEM provides global-scale event streaming with distributed brokers that can span multiple geographies and cloud regions.

Hybrid Integration: AEM enables real-time, event-driven integration across on-premise systems, SAP cloud applications, and third-party solutions, making it suitable for hybrid IT environments.

Enterprise Features: It includes advanced capabilities such as high availability, disaster recovery, dynamic scaling, and fine-grained security for enterprise-grade messaging.

Why the other options are incorrect:

A. SAP Business Technology Platform (SAP BTP) → This is the overall platform-as-a-service offering from SAP. It provides the foundation but not specifically the event streaming capability.

B. SAP Cloud Platform, Integration → This was the older name for what is now SAP Integration Suite (Cloud Integration capability). It does not directly provide advanced distributed event streaming.

C. SAP Process Orchestration → This is the on-premise middleware suite (PI/PO + BPM), but it is not designed for distributed event streaming or modern event protocols like MQTT.

Therefore, the correct answer is D. SAP Integration Suite, Advanced Event Mesh, as it is the only SAP solution purpose-built to deliver distributed, scalable event streaming with support for MQTT, AMQP, and JMS protocols.

In SAP Event Mesh, topic subscriptions follow a defined hierarchical string structure:

Namespace → Defines the domain or context (e.g., sap/s4/beh/businesspartner).

Topic name → Specifies the exact event (e.g., BusinessPartner/Changed).

Separators (/) → Used to concatenate namespace and event details into a full subscription string.

Other options:

API key, Client ID, and Authentication token → Used for connectivity but not part of the topic string.

Business Partner ID, Change type, Event timestamp → Payload details, not part of the subscription string.

Source/Target system → Not required for constructing the topic name.

Thus, the correct components are Namespace, Topic name, Separator.

API Management in SAP Integration Suite supports HTTP-based protocols.

Supported → SOAP, OData, REST (OpenAPI).

Not supported directly → RFC and IDoc (these are legacy SAP protocols handled via Cloud Integration or On-Premise adapters, not via API Management).

Thus, the correct supported message protocols are SOAP and OData.

The Clean Core Approach emphasizes keeping the SAP digital core free from modifications and isolating custom code:

Separation of Concerns → Custom logic/extensions are isolated from SAP standard functionality, ensuring upgrades and innovations are not disrupted.

Other principles (modular design, coding standards, reusability) are good practices but not specifically tied to Clean Core’s goal of isolating custom code.

Thus, the correct principle is Maintain separation of concerns.

For asynchronous processing in a SOAP adapter (SAP Cloud Integration):

Use Message Exchange Pattern = One-Way → Indicates no response is expected.

Choose Process Settings = Robust → Ensures message reliability and error handling in async flows.

Other combinations:

Request-Reply → Used for synchronous scenarios, not async.

WS Standard → Not the correct configuration for async reliability in CPI SOAP adapter.

Thus, correct async configuration is: One-Way + Robust.

In SAP API Management (Integration Suite):

An API Product is a bundle of one or more API Proxies for consumption.

To publish an API Product to API Business Hub Enterprise (Developer Portal), there must be at least one deployed API Proxy included.

Other options:

API Providers are required for connecting to backends, but publishing requires proxies.

No minimum of two is required — just one deployed API Proxy is enough.

In SAP Cloud Integration, integration flows are manipulated using a web-based graphical editor:

Allows drag-and-drop of adapters, mappings, scripts, and process steps.

Provides visual orchestration of message flows.

Command-line and raw code editors are not supported for iFlow design (though XML behind the iFlow exists, it is not directly edited by developers).

Thus, the editor is the Graphical editor.
