CAP natively supports consumption of external services using:

C – OData

CAP provides:

OData service proxies

EDMX import

Automatic CDS generation

OData V2/V4 support

Query transformation & protocol handling

OData is the primary protocol for SAP S/4HANA APIs.

D – REST

CAP supports:

OpenAPI import

REST clients via CAP service proxies

Typed request/response handling

Destination-based outbound REST calls

Why the Others Are Incorrect:

A – WebSockets:

CAP does not provide native WebSocket consumption APIs.

B – SOAP:

SOAP is not supported directly; integrations require external libraries or wrappers.

When connecting from a CAP application to thesandboxof SAP API Business Hub (now SAP Business Accelerator Hub) for APIs such as theBusiness PartnerOData service, the learning content and examples describe that:

The sandbox environment is protected by anAPI keythat must be sent in a specific HTTP header (for example, APIKey or similar) with each request.

Tutorials for CAP/Cloud SDK and S/4HANA integration in a training context show configuration steps where developers obtain anAPI keyfrom the hub and configure it in a destination or in custom code for outbound calls.

This matches optionC – API key.

Why the other options are incorrect:

A – Client certificate:Client certificates are common for productive mutual TLS connections, not for the public sandbox.

B – Service principal:“Service principal” is an Azure-specific concept and not how the sandbox on SAP API Business Hub is accessed.

D – OAuth token:Many productive APIs use OAuth 2.0, but thesandboxin the official exercises is specifically accessed using an API key.

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.

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.

SAP guarantees thatpublic APIs, CDS views, business events, and OData servicesexposed as “whitelisted” or “released” remainstable and backward compatibleacross quarterly upgrades.

Therefore:

Extensions built on these APIs continue functioning regardless of SAP internal changes.

SAP ensures upgrade compatibility through semantic versioning and API lifecycle policies.

Side-by-side and in-app extensibility both rely on stable released interfaces.

Thusoption C is the fundamental reasonwhy extensions remain unaffected.

Why the Others Are Incorrect:

A:The VDM may evolve, but stability is guaranteed only forreleased interfaces, not the whole VDM.

B:Running on BTP alone does not guarantee stability—stability comes from SAP’s API contract guarantee.

D:There is no mechanism that “freezes” APIs; SAP maintains them as stable by contract.

Pods in Kubernetes:

Are the smallest deployable unit (A).

Encapsulate one or more containers (C) that share network and storage namespaces.

Incorrect options:

B: Persistent storage is handled via volumes and claims, not pods.

D: Pods can wrap one or multiple containers; not limited to one.

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.

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.

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.

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.
