C_CPI_2506 SAP Certified Associate - Integration Developer Questions and Answers

When an OData service is created through an API Provider in SAP API Management:

The system can automatically generate an OpenAPI specification from the OData service.

A Swagger UI is automatically created to enable interactive testing and documentation.

Other options:

WSDL specification → Used for SOAP-based services, not OData.

RAML specification → Supported, but not auto-generated by SAP API Management for OData services.

Hence, the correct advantages are:

Swagger UI generation

In API Management (part of SAP Integration Suite), when you create an API Product (which bundles API Proxies for consumption):

Publishing is required before it becomes visible in API Business Hub Enterprise (Developer Portal).

If the product is not yet published, it remains in the design-time environment and is invisible to app developers.

Only published products are available for subscription and discovery.

Other options:

The product will not be shown grayed out or with a “not published” note; it simply won’t be visible at all in the Business Hub Enterprise.

In a microservices architecture, applications are decomposed into multiple smaller services communicating via APIs. This results in:

Increased API traffic due to inter-service communication.

Higher need for governance: enforcing policies, security, throttling, and quotas.

Comprehensive monitoring required to trace calls across multiple distributed services to ensure performance, reliability, and compliance.

SAP Integration Suite’s API Management provides these capabilities:

Traffic management (quotas, rate limiting).

Security policies (OAuth, API keys).

End-to-end monitoring & analytics for distributed calls.

Thus, the correct answer highlights the need for more robust API management and monitoring in high-volume, microservices-driven landscapes.

In Event-Driven Architecture, resilience is ensured by:

Loose coupling → Services do not depend on each other’s runtime availability. A failure in one service does not directly impact others.

This design minimizes cascading failures that can occur in tightly coupled systems.

Asynchronous communication and error handling help further, but loose coupling is the fundamental characteristic that limits failure propagation.

Incorrect options:

A → Robust error handling is important but not the main architectural limiter of cascading failures.

C → Centralized logging helps with troubleshooting, not failure prevention.

D → Asynchronous buffering mitigates impact but loose coupling fundamentally prevents direct propagation.

For a synchronous call to a remote HTTP API in an integration flow:

The OData adapter (or HTTP adapter) is used to perform synchronous request-reply communication with REST-based services.

AMQP → Messaging protocol, not synchronous.

SFTP → File-based transfer, asynchronous.

Mail → For SMTP/IMAP, not synchronous API calls.

Thus, the correct adapter for a synchronous remote API call is OData (or HTTP adapter, depending on configuration).

SAP Integration Suite is the strategic integration platform-as-a-service (iPaaS) from SAP. It provides a comprehensive set of integration capabilities for hybrid and multicloud landscapes.

It connects on-premise SAP systems, cloud SAP solutions (e.g., S/4HANA Cloud, SuccessFactors, Ariba), and third-party applications.

It offers capabilities like Cloud Integration, API Management, Event Mesh, Open Connectors, and Integration Advisor to support various integration patterns.

SAP explicitly positions Integration Suite as the solution to manage end-to-end integrations across heterogeneous and distributed IT landscapes.

Other options:

SAP Cloud Platform Integration was the older name of Cloud Integration (now part of Integration Suite).

SAP Process Orchestration is the legacy on-premise middleware and not designed for multicloud/hybrid environments.

SAP BTP is the overall platform; integration is only one capability within it.

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.

In SAP Cloud Integration, when configuring Exchange Properties in a Content Modifier, supported Java data types include:

java.lang.String → The most common type.

java.lang.Integer → Numeric properties can be stored.

Other options:

java.lang.string and java.lang.integer → Invalid, because Java types are case-sensitive.

Thus, correct types are java.lang.Integer and java.lang.String.

In API Management (SAP Integration Suite), when implementing Basic Authentication policies:

If the AssignMessage policy does not correctly assign credentials to the request message, authentication will fail.

This results in HTTP 401 Unauthorized.

Other tags like preFlow, postFlow, response are policy flow phases, but the credentials must be applied to the request for proper authentication.

Thus, the root cause is when the Assign To = request is missing/misconfigured.

In an event-driven architecture (EDA), several messaging patterns exist:

Point-to-Point → Enables direct communication between exactly two parties (sender and receiver) without intermediaries.

Publish-Subscribe → Multiple consumers subscribe to events; requires a broker/intermediary (like Event Mesh).

Message Queue → Relies on a queue as an intermediary between producer and consumer.

Event Sourcing → Refers to storing state changes as events, not a communication pattern.

Therefore, the only pattern allowing direct communication without an intermediary is Point-to-Point.

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.

In SAP Integration Suite, Event Mesh (EMIS), queue creation and management requires specific role collections assigned to the user in SAP BTP:

EventMeshAdmin → Provides full administration rights (create, delete, configure queues, topics, subscriptions).

EventMeshDeveloper → Allows development tasks, including working with queues and topic subscriptions.

Other options are not correct:

Message client administrators group membership → Not a BTP role collection concept.

Administrator privileges on Event Mesh → Too generic; the system enforces access through role collections.

Sufficient authorization within emis-s4hana system → S/4HANA authorizations do not govern Event Mesh capabilities.

Thus, the minimum permission required is assignment of the Event Mesh role collections in BTP.

In SAP Cloud Integration (part of Integration Suite), error handling within integration flows is implemented using:

Exception Subprocesses → Dedicated subprocesses triggered by an Error Start Event to handle unexpected runtime exceptions.

These allow logging, error notifications, or compensating logic.

Other options:

Try-Catch subprocesses → Not a modeling construct in SAP CPI.

Exception handler integration flow elements → Not a standard artifact; error handling is done with exception subprocesses.

Status code checks → Useful for response validation but not full error handling.

Thus, the correct answer is Exception-handling subprocesses.

In SAP API Management, supported API description languages include:

RAML (RESTful API Modeling Language)

OpenAPI Specification (OAS, formerly Swagger)

Both are industry-standard languages for modeling REST APIs.

Other options:

A. HTML → A markup language for UI, not an API modeling language.

D. CXML (Commerce XML) → A B2B procurement standard, not for API modeling.

In SAP Cloud Integration, during development and testing:

The Content Modifier can be used to insert or simulate payloads, headers, or properties.

This allows developers to test flows without requiring external calls.

Other options:

SOAP Adapter → Used for SOAP communication, not payload simulation.

General Splitter → Splits incoming payloads, doesn’t simulate.

Data Store Operations → Manages stored messages, not simulation.

Thus, the correct component for simulated payloads is Content Modifier.
