CLEAN CERTIFICATION 2025
EXAM QUESTIONS AND 100%
VERIFIED CORRECT
ANSWERS!!!
What model enforces separation between SAP and custom code?
SAP S/4HANA Cloud Extensibility Model.
What are the two types of extensions within SAP S/4HANA Cloud?
On-stack extensions (key user/developer) and side-by-side extensions (SAP BTP).
What are the three extension types by location?
Type 1: Key-user on-stack; Type 2: Developer on-stack; Type 3: Side-by-side via SAP BTP.
What type of coupling do side-by-side extensions provide?
Loosely coupled to SAP S/4HANA Cloud.
What must extensions use to remain clean core compliant?
Only released local or remote public APIs and extension points (BAdIs, BOs).
What does the use of released APIs and technologies enable?
Upgrade stability and clean separation between SAP and custom logic.
What model defines cloud-compliant ABAP development?
ABAP Cloud Development Model.
What language check ensures compliance in ABAP Cloud?
Syntax checks for only approved language features and released APIs.
What tools are used to build ABAP Cloud objects?
, ABAP development tools for Eclipse.
What model allows different extension options for varying customer cloud journeys?
Three Tier Extensibility Model.
What is Tier 1 in the extensibility model?
Cloud-compliant development using ABAP Cloud and SAP extensibility model (mandatory
for public edition).
What is Tier 2 in the extensibility model?
Wrapper-based approach using released objects to call unreleased objects (used in private/on-
premise).
What is Tier 3 in the extensibility model?
Classical extensions (discouraged, used only when Tier 1/2 are not feasible).
What risk is associated with Tier 3 extensions?
High disruption during upgrades or cloud migration.
What methodology helps define extension strategy and target architecture?
SAP Application Extension Methodology.
What tools support cloud-compliant side-by-side extensions?
SAP Business Technology Platform (SAP BTP).
Why must the need for extensions be precisely understood?
To select the proper extensibility type (on-stack vs. side-by-side) and avoid future disruption.
What should never be duplicated in a custom extension?
Standard functionality provided by SAP S/4HANA Cloud.
What is the mantra of clean core for data?
Keep the data clean.
