SAP C_CPE_2409 - SAP Certified Associate - Backend Developer - SAP Cloud Application Programming Model

The Kyma project (used in SAP BTP, Kyma runtime) is an extension framework that provides modular building blocks to extend applications using Kubernetes-native components. The official Kyma module list includes:

Serverless (A): Provides functions-as-a-service capabilities, enabling lightweight event-driven workloads.

Telemetry (C): Offers logging, metrics, and tracing capabilities enhancing observability.

API Gateway (E): Enables secure and managed exposure of APIs, including authentication and routing.

Incorrect options:

B – Data Warehouse: Not a Kyma module.

D – Storage: Storage is a Kubernetes concept, not a Kyma module.

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

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.

Comprehensive and Detailed Explanation

Authorization flow in SAP BTP:

Scopesare defined in XSUAA.

Scopes are grouped intorole templates.

Role templates becomerolesin the subaccount.

Roles are assigned tousers.

Role collections group roles for easier assignment.

If a user cannot access an app:

The most common cause is:

C – Roles aren’t assigned to the user

Without receiving the required role, the user’s JWT tokendoes not contain the required scopes.

Even if:

Scopes exist

Role templates exist

Role collections exist

…the user mustexplicitlyhave the role (or role collection) assigned.

Why the Others Are Incorrect:

A:Client applications don’t require role assignments.

B:Role collections may be assigned, butroleassignment is the critical missing piece in this scenario.

D:Client applications do not need role collections.

C – Define role templates in xs-security.json

xs-security.json is the core XSUAA configuration file. It defines:

Role templates

Scopes

Attributes

Authorization semantics

To secure the app, developers must definerole templates, which determine which scopes a role grants.

B – Use role names in application descriptors (web.xml in Java apps)

For Java web apps running via Tomcat/Servlet containers,web.xmldefines application-level roles and maps them to XSUAA role templates.

Thus, restricting access involves linking:

web.xml roles → XSUAA role templates → scopes → permissions

Why A and D Are Incorrect:

A:In xs-app.json, scopes define access rules forHTML5 apps via approuter, not Java applications.

D:Scopes belong to xs-security.json, but setting them alone does not restrict application access unless roles and mappings are defined. The question focuses onstepsto restrict access, and B + C describe the necessary actions.

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.

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.

To expose a data model in CAP:

You needdata model entities (D)defined in CDS.

You must create aservice definitioncontainingservice entities (A)that expose selected data model entities.

Associations and aspects are optional modeling features and do not by themselves expose a model.
