Free Practice Questions for SAP C_CPE_2409 Exam

In Cloud Foundry, when you deploy an application with cf push (without a pre-built container image), the platform runs astaging phase. During staging:

Abuildpackinspects the application, detects the runtime (for example, Node.js, Java, Python), anddownloads required dependencies.

It then produces adroplet, which is the runnable artifact containing the application and its runtime environment. This droplet is conceptually similar to acontainer imagethat is later executed by the platform.

Therefore, the role of the buildpack is best summarized as:

It builds the runtime image for applications during staging.

This matches optionD – It builds a container image for applications during staging.

Why the others are incorrect:

A – Binds services to applications:Service binding is managed by the Cloud Foundry platform (cf bind-service and environment variables), not by buildpacks.

B – User roles and permissions:Roles and permissions are handled by UAA/XSUAA and platform role assignments, not by buildpacks.

C – Database manager:Databases are provisioned as services; buildpacks do not manage database servers.

In CAP:

destinations.json (A):

Used during local development to define destinations mapped to external services. CAP automatically loads these destinations when running locally.

package.json (D):

Contains the requires section where CAP services declare dependencies on external services. This indicates how the destination should be consumed by CAP runtime (e.g., which kind of service is required and where to get credentials).

Incorrect options:

B – manifest.json: Not used in CAP backend runtime.

C – services.xml: Not part of CAP configuration.

Namespaces in CDS:

Group related entities and types (B):Namespaces help organize models into logical domains.

Manage version or ownership separation (C):Different namespaces allow parallel evolution of models or clearer ownership boundaries.

Incorrect options:

A:Namespaces have no impact on performance.

D:No styling semantics exist in CDS namespaces.

OData protocol specifies:

PATCH is used for partial updates, where only changed fields are provided.

PUT performs complete replacement of an entity.

POST is used for create operations or invoking actions.

Thus, partial updates in OData use the PATCH method.

A scope in XSUAA is:

A technical authorization value included in OAuth tokens.

Used to determine whether a user/app has permission to invoke specific CAP service operations.

Incorrect options:

A: Scopes do not store credentials.

C: Subaccounts are BTP landscape units.

D: Roles aggregate scopes, not vice versa.

Comprehensive and Detailed Explanation

SAP Gardeneris an open-source project used by SAP BTP Kyma runtime as thecluster management layer.

Key responsibilities include:

Provisioning Kubernetes clusters on different hyperscalers

Managing lifecycle operations (creation, upgrade, repair)

Standardizing Kubernetes across cloud providers

Ensuring SLA-grade operations and reliability

Monitoring and auto-healing clusters

Kyma runtime runson top of Gardener-managed Kubernetes clusters, enabling SAP to deliver a fully managed Kubernetes experience.

Why the Other Options Are Incorrect:

A:Applications are deployed by the developer or CI/CD pipeline, not Gardener.

B:Subaccounts and instances belong to BTP cockpit—not Gardener.

SAP BTP provides:

Integration (A): A full suite of integration services for apps, data, and processes.

Application Development (B): Tools and runtimes for building new extensions or applications.

Extensibility (C): Allows extending SAP S/4HANA Cloud, SuccessFactors, and on-premise systems side-by-side.

Incorrect option:

D – Build tightly coupled applications:

SAP BTP promotes loose coupling, modularity, and clean extension approaches.

In XSUAA security model:

Roles group multiple scopes.

Role collections group multiple roles, not scopes.

Scopes are the finest-grain authorization units.

Therefore, the entity that holds several scopes is the Role (B).

Incorrect options:

A: Role collections bundle roles, not scopes directly.

C: A scope is a single authorization unit.

D: User groups are not part of XSUAA authorization structures.

Comprehensive and Detailed Explanation

To call on-premise systems (e.g., ECC, on-prem S/4HANA, custom OData services), CAP requires:

D – Cloud Connector

The Cloud Connector creates asecure tunnelbetween SAP BTP and the on-prem network.

It maps internal systems and resources (paths, ports) to virtual on-demand resources that BTP can access.

Without Cloud Connector, BTP services cannot reach the on-prem landscape.

B – Destination Service

CAP applications rely onDestinationsto configure:

Hostnames and URLs

Proxy types (onPremise)

Authentication mechanisms

SAP Cloud Connector location IDs

System routing metadata

Outbound CAP service calls use destination configuration to find the on-premise endpoint.

Why the Other Options Are Incorrect:

A – API Management:

Useful for external API governance but not mandatory for on-premise connectivity.

C – Event Mesh:

Used for event-driven communication, not direct connectivity to legacy/on-prem services.
