SAP C_CPE_2409 SAP Certified Associate - Backend Developer - SAP Cloud Application Programming Model Exam Practice Test

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.

To build a Java (Spring Boot) application with the SAP Cloud SDK:

Java SE Development Kit 8 (A): Minimum required Java runtime.

Apache Maven 3.5+ (B): Required build tool for Java-based SDK modules.

Incorrect options:

C: MDK is for mobile app development, unrelated to Cloud SDK Java backend.

D: Spring Initializr can be used optionally but is not required; it is a development aid, not a requirement.

In SAP CI/CD service, low-code project pipelines (e.g., SAP Build Apps or SAP Build Work Zone content) can release artifacts by:

Deploying to Cloud Foundry (B):The pipeline packages and deploys artifacts to the Cloud Foundry runtime.

Deploying to Cloud Transport Management Service (C):Used for landscape-aware transport of application modules.

Incorrect options:

A:Private server deployment is not supported by SAP CI/CD predefined pipelines.

D:FTP uploads are not part of SAP CI/CD Release stage capabilities.

Comprehensive and Detailed Explanation

SAP BTP Cloud Foundry runtime is aPlatform-as-a-Service (PaaS)that provides:

Fully managed multi-language runtimes (Node.js, Java, Python, Go)

Buildpacks to build container images

Autoscaling and health management

Route-based load balancing

Secure isolation of application environments

Service binding for XSUAA, Destinations, HANA Cloud, etc.

Its primary purpose is to runcloud-native, 12-factor applications.

Why the Other Options Are Incorrect:

A:S/4 configuration is done via SAP GUI/Fiori, not Cloud Foundry.

C:HANA databases are managed through SAP HANA Cloud administration tools, not Cloud Foundry.

D:Integrations use SAP Integration Suite or API Management, not Cloud Foundry runtime.

Kubernetes command usage:

kubectl create -f <filename>explicitly creates resources defined in the YAML file, including Pods.

While kubectl apply can also create resources, the question asks specifically for the commandused to createa Pod, which aligns withcreate -f.

Incorrect options:

A:kubectl run is used to create pods from images, not YAML files.

B:kubectl get pod is only for listing.

C:apply is for declarative management but not the direct answer for explicit creation.

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.

@cap-js/telemetry enhances CAP observability and automatically publishesruntimeanddatabasemetrics.

B – Memory Usage Metrics

Telemetry captures Node.js process metrics such as:

Heap usage

Resident Set Size (RSS)

Garbage collection metrics

Memory allocations and consumption patterns

These help diagnose memory leaks or heavy load conditions.

C – Database Pool Statistics

Telemetry gathers database-layer metrics such as:

Active/idle database connections

Pool usage and saturation

Connection acquisition time

Query execution statistics

These metrics are critical for diagnosing bottlenecks in SAP HANA Cloud or SQLite adapters.

Why the Others Are Incorrect:

A – Network latency and jitter:

Telemetry does not measure network latency at the protocol layer.

This requires external APM or monitoring tools.

D – CPU allocation / thread management:

CAP telemetry exposes basic CPU metrics only through Node.js process stats but does not provide deep OS-level CPU or thread-management metrics.

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.

In SAP Continuous Integration and Delivery, each CI/CD job is linked to a remote Git repository.

DefiningSCM credentialsenables the job to:

Authenticate against Git (for example, GitHub, GitLab, SAP Git).

Retrieve theproject source codeduring pipeline execution.

Clone the repository and run build, test, and deploy steps.

This aligns precisely withA.

Incorrect options:

B:Credentials are not “managed” by the job; they are only used for authentication.

C:The CI/CD service never modifies source code automatically.

In CAP, external services are typically defined using:

service.cds or additional CDS files that declare:

using { API as ExternalService } from './external-service.edmx';

This integrates the external OData metadata into the CAP model layer.

CAP convention loads external models annotated in CDS files, making service.cds the default place for such declarations.

Incorrect options:

A – index.js: Holds custom logic, not service definitions.

B – package.json: Lists dependencies and scripts.

C – manifest.json: Not used in CAP backend projects.

Kyma is a Kubernetes extension framework that provides:

Eventing

Serverless functions

API Gateway

Observability modules

Application connectivity

It extends Kubernetes with enterprise-ready features, not replace it.

Incorrect options:

B: Kyma hosts applications but its purpose is extension, not pure development.

C: Kyma relies on Kubernetes; it does not replace it.

D: VM management is unrelated to Kyma.

TheSAP Cloud SDKis designed to simplify and standardize buildingside-by-side extensions(primarily in Java and JavaScript/TypeScript) for SAP S/4HANA and other SAP solutions.

Typical use cases described in the SDK documentation and training are:

Advanced features such as resilience and caching (B):The SDK providesresilience libraries(circuit breakers, retries, timeouts) andcaching mechanismsaround outbound calls to SAP S/4HANA. This allows backend developers to implement robustness and performance patterns without building them from scratch.

Add new features to an existing Java application (C):There are project templates and libraries forJava (Spring Boot). You can integrate the SDK into an existing Java application to call SAP S/4HANA APIs using the VDM and benefit from resilience, logging, and multitenancy support.

Why the other options are incorrect:

A – Allow key users to create fields:This relates toin-app extensibility (key-user extensibility)within SAP S/4HANA (for example, Custom Fields and Logic), not SAP Cloud SDK.

D – Build extensions using .NET:Officially supported runtimes for SAP Cloud SDK areJavaandJavaScript/TypeScript, not .NET.

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.

In observability:

Prometheus (A):

Used for metrics scraping and monitoring, and commonly integrated with BTP systems (especially Kyma).

Logstash (C):

Part of the Elastic Stack, used for log forwarding and transformation, can be integrated with BTP for centralized logging pipelines.

Incorrect options:

B – Terraform: An IaC tool, not an observability tool.

D – Jenkins: A CI/CD tool, not for observability.

CAP’s security architecture relies on:

XSUAA service (C):Provides OAuth 2.0 authorization, JWT tokens, scopes, and role templates for CAP services.

SAP Cloud Identity Services (D):Handles identity provisioning, authentication, and trust relationships, used along with XSUAA.

Side-by-side extensibility is the recommended extensibility model for SAP S/4HANA Cloud when building advanced, decoupled, and scalable extensions. It allows developers to build and run applicationsoutsidethe S/4HANA core using SAP BTP services.

Correct Options Explained:

B – Integration with cloud and non-cloud solutions

Side-by-side extensions run on SAP BTP, which includesIntegration Suite,API Management,Event Mesh, and connectivity services.

This enables:

Integration withSAP SaaS systems(SuccessFactors, Ariba, SAP S/4HANA Cloud).

Integration withon-premise systemsvia Cloud Connector.

Communication withthird-party and non-SAP systems.

Thus, B is correct.

C – Uses a complete development platform

SAP BTP provides:

Multiple runtimes (Cloud Foundry, Kyma/Kubernetes, ABAP environment).

Database and storage options (SAP HANA Cloud, document stores).

Security, authorization, and multi-tenancy capabilities.

DevOps support (CI/CD, transport management).

Language runtimes (Java, Node.js, CAP, Python, etc.)

This makes SAP BTP afull development and operations platform, supporting the building and hosting of side-by-side extensions.

D – Support for hybrid scenarios

Side-by-side extensibility supports hybrid architectures by enabling:

Connectivity betweencloud and on-premise systems.

Event-driven integration between systems deployed across different landscapes.

APIs and events from both cloud and on-prem to be consumed and extended.

Thus, D is correct.

Why A is Incorrect:

Side-by-side extensionsdo not run in the same software stackas SAP S/4HANA.

They runoutsidethe S/4HANA core on SAP BTP, ensuring:

Loose coupling

Upgrade stability

Clean core compliance
