C_ABAPD_2507 Exam Dumps - SAP Certified Associate - Back-End Developer - ABAP Cloud

Comprehensive and Detailed Explanation From Exact Extract:

Modern ABAP encourages well-structured OO patterns under ABAP for Cloud Development, with static checks and typed APIs. A singleton is realized by:

Preventing external instantiation (CREATE PRIVATE).

Holding a static reference attribute to the single instance.

Providing a public static factory (get_instance) that returns the single instance.This aligns with the ABAP Cloud guidance on architecture-driven, upgrade-stable design (strict language, typed APIs, static checks).

(C) is wrong: the factory method must be public so callers can get the instance.

Comprehensive and Detailed Explanation from Exact Extract:

dats_add_days → ✅ Returns the number of days added/subtracted to a given date → INT4.

dats_days_between → ✅ Returns the number of days between two dates → INT4.

dats_add_months → ❌ Returns a DATE, not INT4.

dats_is_valid → ❌ Returns a BOOLEAN (flag), not INT4.

In CDS, these date functions are used for calculations in queries, supporting business logic pushdown.

Comprehensive and Detailed Explanation From Exact Extract:

To redefine a component in a subclass:

The component (method) in the superclass must be defined with the FOR REDEFINITION addition.

In the subclass, you use the REDEFINITION clause in the method declaration and implement the method in the subclass to override the superclass behavior.

Thus:

Option A is correct because the method declaration in sub1 must include the REDEFINITION addition.

Option D is correct because the actual redefined method implementation must be provided in the subclass sub1.

Option B is incorrect because the component is not re-implemented in the superclass.

Option C is incorrect because REDEFINITION is not added in the superclass, but FOR REDEFINITION is.

RAP defines the architecture for OData services based on CDS semantic data models and ABAP behavior—this is the current model.

The predecessor is the ABAP Programming Model for SAP Fiori (BOPF/CDS-based), which can be migrated into RAP; it also exposes ABAP backend logic via CDS semantics.

ABAP Cloud Development Model (B) is the rule set/contract (release contracts, checks), not the service-building model. CAP (C) targets Node.js/Java on BTP, not ABAP-based backend services.

Extensions in SAP S/4HANA Cloud must follow the ABAP Cloud Extensibility Model.

Use released APIs (D) → Only released and whitelisted APIs are permitted.

Use predefined extension points (B) → Extensions can only be made where SAP has defined extension includes or APIs.

Build at UX layer (A) and Use CI/CD pipelines (C) are good practices but not mandatory extension rules.

Comprehensive and Detailed Explanation from Exact Extract:

SAP S/4HANA Cloud Extensibility Framework defines personas for extension activities:

Business Experts → implement extensions with business knowledge (using in-app extensibility).

Citizen Developers → build extensions with low-code/no-code tools.

Report Writer and Workflow Administrator are roles, but not part of extensibility personas.

Comprehensive and Detailed Explanation From Exact Extract:

In RAP/ABAP Cloud, authorization objects define authorizations for roles and are invoked from CDS (read) and behavior (modify). This ties app operations to authorization objects and roles administered in IAM.

RAP services are exposed for Fiori apps via service bindings; the resulting Fiori app uses the service and its enforcement (which includes the authorization objects configured for roles). Putting it together for S/4HANA Cloud IAM: Apps carry/trigger checks based on authorization objects; Business Catalogs collect apps; Business Roles collect catalogs; Business Users are assigned roles. This aligns with the ABAP Cloud guidance that authorizations are grouped into roles and checked against authorization objects during access.

Comprehensive and Detailed Explanation From Exact Extract:

ABAP for Cloud Development emphasizes expression-oriented, typed programming with strong static checks (e.g., constructor/operators, REDUCE, COND, etc.), which is the modern ABAP style used in RAP.

ABAP integrates built-in database access tightly via CDS and Open SQL; CDS entities are the building blocks and govern data access that the runtime executes via the SQL view.

(A) is false (ABAP is statically typed). (B) is false (ABAP keywords are not case-sensitive).
