1. Can you explain what exactly DevOps is?
DevOps refers to the practises used by software development teams to increase an organisation’s agility and ability to deliver applications and services at a swifter pace than conventional software development processes allow.
2. What is the purpose of DevOps tools?
DevOps software is computer software that aims to help streamline communication and collaboration between a company’s product managers, software developers, and IT operations professionals.
3. Can you explain the term continuous delivery?
Continuous delivery is a software development practice that automates the delivery of working software in small batches to external sites and to customers as notified. It allows for continuous testing so developers can verify application updates across multiple dimensions before deploying to customers.
4. How is continuous delivery different from DevOps?
The basic difference between DevOps and continuous delivery is that DevOps work like an assembly line, whereas continuous delivery is like a conveyor belt that quickly and seamlessly gets services from the factory floor to the customer.
5. How many types of extensibility are available in SAP?
There are mainly three types of software extensibility –
- white-box extensibility
- grey-box extensibility
- black-box extensibility
6. Can you explain the key user extensibility in SAP?
Key User Extensibility enables you to include additional fields in object definitions and add those fields to the object’s respective Fiori UI without requiring changes to the underlying code or integration between multiple systems. This allows the users to make minor changes in the interfaces.
7. How would you define extensibility in S 4HANA?
Extensibility covers a broad spectrum of topics that allow customers and partners to adopt standard business software to their business needs. This includes the ability to customize standard business software, such as adding new fields or logic to forms or reports, altering how information on a form is presented to the user, integrating with another application by sharing data between applications, and changing the navigation and layout of a user interface.
8. Can you name the key advantages of SAP’s 4HANA extensibility?
The advantages of SAP S/4HANA extensibility are –
- Lower efforts in software upgrades.
- More upgrades, that leads to faster innovation cycles.
- Enables very agile implementation, that results in shorter implementation cycles.
9. Can you explain the term in-app extensibility?
In-App Extensibility allows the generation of SAP S/4HANA extensions. It enables key users to generate fields, business logic, CBOs, etc.
10. How would you define side-by-side extensibility in SAP?
With side-by-side extensibility, you can integrate external content such as services, applications, or events into a SAP Customer Experience system by deploying it through APIs and development platforms. Users with in-depth knowledge of technicalities usually prefer this extensibility.
11. Can you name a few advantages of side-by-side extensions?
With Side-by-Side Extensibility, you can build external apps in the SAP Cloud Platform that read and write data to your S/4HANA Cloud. Applications can use both standard communication scenarios, and custom ones based on your Custom Business Objects.
12. What are the elements of SAP Cloud Platform that support the creation of extensions?
SAP Cloud Platform provides these components and concepts for the making of extensions :
- SAP Cloud Platform Extension Factory.
- SAP Cloud Application Programming Model (CAP)
- ABAP RESTful Programming Model (RAP)
13. What are the three main pillars of SAP Extension Suite?
Following are the three main pillars of the SAP Extension Suite –
- developing apps faster, by implementing low-code and no-code application development and automation.
- Provide agile process automation to enhance processes and tasks.
- Linking people, data, and processes together, with indulging experiences.
14. Can you explain what the SAP Cloud SDK (C_S4CDK_2021) is?
The SAP Cloud SDK (C_S4CDK_2021) is a comprehensive toolset for developing cloud-native extension applications for SAP. Based on Java and JavaScript libraries, it offers developers the flexibility to work with the programming language most appropriate for their use case and reduces the boilerplate code typically included in an application when interfacing with SAP solutions.
15. What is SAP Security?
SAP security is a complex process of guarding the SAP data and applications against unwanted use and access. SAP provides various tools, operations, and measures for security checks to guard this information. SAP security ensures that only the authorized users can use the functionality of SAP.
16. What is meant by Web application security?
Security for web applications includes a collection of techniques, technologies, and measures applied to web servers, web applications, and web services such as APIs to protect them from attack.
17. What types of testing are there in SAP?
- Unit Testing
- Integration Testing
- Functional Testing
18. What are the steps to perform a performance test in SAP?
These are the steps of SAP performance testing –
- Test creation.
- Test editing.
- Test validation.
- Workload emulation with schedules.
- Schedule execution.
- Evaluation of results.
19. What are the extensibility tasks that can be done on SAP S/4HANA (C_S4CDK_2021) cloud?
The following extensibility tasks can be done SAP’s 4HANA cloud –
- Create new fields in the UI from the field repository.
- Add new field groups, move fields into groups, combine or split fields from one line, etc.
- Show or hide fields or field groups.
20. How would you define SAP methodology?
The accelerated SAP (ASAP) methodology is the standard procedure that project managers use to implement a SAP system, which takes maximum advantage of available resources.
21. Can you name the characteristics of the SAP Activate methodology for SAP S/4HANA cloud?
Here are some of the key characteristic of the SAP Activate methodology –
- Fit-to-Standard System Preparation.
- Verify Fit-to-Standard System.
- Fit-to-Standard Analysis Preparation.
- Prepare for Fit-to-Standard Workshops.

Following are the phases of SAP’s Activate methodology –
- prepare
- explore
- realize
- deploy
23. Which of these does the SAP Activate employ – agile or waterfall?
SAP Activate combines the best elements of Waterfall and Agile methods, as well as being prescriptive, literal and much more specific than either of its predecessors. Unlike other approaches to software development, Activate is also applicable to On-Premise, Cloud or Hybrid implementations.
24. Can you name the 3 pillars of SAP Activate?
The 3 pillars of SAP Activate are –
- Methodology,
- Best Practices,
- Guided Configuration.
25. How is SAP’s 4HANA different from SAP’s 4HANA cloud?
The On-premise and Cloud versions of SAP S/4HANA differ in how they are hosted and maintained. The Cloud edition is Software as a Service (SaaS), meaning it is hosted on SAP’s servers and maintained entirely by SAP. However, in case of cloud versions, software upgrades occur automatically, without the need for on-premises infrastructure
26. Which are the main components of SAP Activate?
Components of the SAP Activate –
- project management
- customer team enablement
- technical architecture and infrastructure
- application design and configuration
- extensibility, integration, testing
- data management and operations
27. How would you define SAP multi-tenancy?
Multitenancy is a software architecture in which multiple tenants share the same hardware or infrastructure, but keep the data separate, have separate access rights, and have access to their own identity management system.
28. What are the advantages of Multi Tenancy?
- It’s cost-effective.
- It’s easily scalable.
- It’s secure and offers more privacy.
- It’s a better use of resources.
- It’s maintenance-free for the customer.
29. In what ways can multi-tenancy be implemented?
Following are the two approaches that we can use to implement multi-tenancy –
- Database per Tenant: Every Tenant has its respective database and is isolated from other tenants.
- Shared Database, Shared Schema: A common database is shared by all the tenants. Columns in the tables tell who is the owner of the row.
30. Can you tell about the characteristic feature of multi-tenancy?
Multitenancy is a technique used to provide services to multiple customers from a single instance of an application and hardware platform. The applications are designed to segregate the data belonging to the various customers so that they do not see or share each other’s data.
