Practice Free C_CPE_2409 SAP Certified Associate - Backend Developer - SAP Cloud Application Programming Model Exam Questions Answers With Explanation

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.

Cloud Foundry CLI uses:

cf api to set or view the target Cloud Foundry API endpoint before logging in.

Other commands:

cf login: authenticate against the already-set endpoint.

cf target: view/set org and space.

cf endpoint: not a valid command.

SAP’s CI/CD service includes aTest stagethat allows automated deployment into aCloud Foundry environment(usually a dedicated test or dev space). This enables:

Running automated integration tests

Validating Cloud Foundry-bound services (XSUAA, Destinations, HANA Cloud, etc.)

Ensuring deployability before production transport

The Test step does not deploy into local or private servers; it uses Cloud Foundry runtime as the standardized environment.

Comprehensive and Detailed Explanation

AMultitarget Application (MTA)is the SAP-recommended packaging format for complex applications that involve multiple modules (for example, CAP service, UI, XSUAA, destination service). MTAs are deployed as .mtar archives using theCloud MTA Build Tool (mbt)anddeploy service.

Correct Options:

C – Using SAP Business Application Studio

SAP Business Application Studio includes:

A graphical MTA builder

Built-in Cloud MTA Build Tool

Deployment integration with SAP BTP

Wizards for generating mta.yaml

Developers can simply right-click the project ?Build MTA?Deploy MTA Archive.

D – Manually creating and deploying the mta.yaml file

Developers can:

Write or update the mta.yaml (the deployment descriptor).

Use the Cloud MTA Build Tool to build the .mtar.

Deploy using the Cloud Foundry deploy service (cf deploy .mtar).

This is a fully supported and widely used approach.

Why the Other Options Are Incorrect:

A – SAP HANA Cloud tools:

These tools manage HANA databases, not MTAs.

B – cf push:

cf push deploys asingle module.

MTAs must be deployed viadeploy service, not cf push.

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.

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.

CAP development guidelines recommendSQLiteas the default database for local development because:

It requires no installation.

It supports CDS features needed for rapid prototyping.

It enables quick testing without deploying to SAP HANA.

For productive deployments, SAP HANA or SAP HANA Cloud is used, but SQLite remains the recommended local option.

Incorrect choices:

A – NoSQL:CAP does not support NoSQL databases as primary stores.

C – PostgreSQL:Supported via adapters, butnotthe recommended development default.

D – HANA Cloud:Used for production, not recommended for local development.

OData plays a central role in CAP service exposure:

CRUD operations using HTTP verbs (A):CAP services expose entities over OData, supporting GET, POST, PATCH, PUT, and DELETE.

Define request/response behavior (C):OData standardizes request/response structures, headers, status codes, payload formats (JSON/XML), and protocol-level semantics.

Incorrect options:

B:UI generation is achieved by SAP Fiori Elements, not OData itself.

D:OData is not an analytics engine.

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.

Comprehensive and Detailed Explanation

CAP supportsreal-time, event-driven architecturesusing:

D – Message Queues and Event Brokers

This includes:

SAP Event Mesh

Message brokers (AMQP, Kafka via integration adapters)

CAP domain events (emit, on)

Outbox pattern for guaranteed delivery

Event-driven communication between microservices

These features allow:

Loose coupling

Real-time synchronization

Trigger-based data propagation

Integration with SAP S/4HANA event channels

Handling asynchronous workloads

Why the Others Are Incorrect:

A:Database connectivity is synchronous and not event-based.

B:Service connectivity is request/response, not event-driven.

C:Service extensibility allows custom handlers, not messaging.

CAP supports integration with external services using multiple API definition formats.

D – EDMX for OData V2 and V4

CAP can import OData services using:

EDMX files (OData V2/V4)

Metadata downloaded from SAP Business Accelerator Hub

cds import

This generates CDS definitions for entities, actions, and functions.

B – OpenAPI (Swagger)

For REST services, CAP supports:

Importing OpenAPI specifications

Generating CDS service proxies

Creating typed service clients

OpenAPI is the standard way to describe REST endpoints in CAP.

Why the Others Are Incorrect:

A – GraphQL schema

CAP does not directly import GraphQL schemas.

C – WSDL

WSDL (SOAP) is not directly consumed by CAP modeling tools.

In CAP Node.js projects, the .env file is used to store environment variables that influence application behavior at runtime, such as credentials, service endpoints, or configuration flags. It is automatically loaded by CAP during application startup.

CAP guidelines recommend using .env for environment-specific configuration that should not be hard-coded or committed directly into source files.

Incorrect options:

A: Version control settings are handled by Git configuration files.

B: UI settings belong to UI frameworks, not .env.
