Ques:- What are runnable entities and how are they scheduled by the RTE
Right Answer:
Runnable entities are the basic units of execution in AUTOSAR that encapsulate the functionality of a software component. They are scheduled by the RTE (Runtime Environment) based on the configured timing and triggering mechanisms, such as periodic or event-driven scheduling, ensuring that they are executed at the appropriate times according to the system's requirements.
Ques:- What is a VFB (Virtual Functional Bus) in AUTOSAR
Right Answer:
A Virtual Functional Bus (VFB) in AUTOSAR is an abstract representation of the communication between software components, allowing them to interact as if they were connected by a physical bus, without being tied to specific hardware or communication protocols.
Ques:- What is the difference between SAP ABAP and other programming languages
Right Answer:
SAP ABAP is a high-level programming language specifically designed for developing applications on the SAP platform, focusing on business processes and data manipulation within SAP systems. Unlike general programming languages, ABAP integrates tightly with SAP's database and application server, supports modularization through function modules and classes, and includes built-in tools for reporting and data processing specific to enterprise resource planning (ERP) environments.
Ques:- What is a BAPI and how does it differ from a BADI in ABAP
Right Answer:
A BAPI (Business Application Programming Interface) is a standardized programming interface that allows external applications to interact with SAP systems, enabling data exchange and business process integration. A BADI (Business Add-In) is a type of enhancement technique that allows developers to add custom functionality to SAP applications without modifying the original code. The key difference is that BAPIs are used for external communication, while BADIs are used for internal enhancements within SAP.
Ques:- What is COM stack and how does it support data communication
Right Answer:
The COM (Communication) stack in AUTOSAR is a set of software components that facilitate communication between different software components (SWCs) in a vehicle's electronic system. It supports data communication by providing services for message transmission, reception, and management of communication protocols, ensuring reliable and efficient data exchange over various communication channels like CAN, LIN, and Ethernet.
Ques:- What is API versioning and why is it important
Right Answer:
API versioning is the practice of managing changes to an API by assigning version numbers to different iterations of the API. It is important because it allows developers to introduce new features or make changes without breaking existing client applications that rely on older versions, ensuring backward compatibility and a smoother transition for users.
Ques:- What is the difference between GET, POST, PUT, and DELETE in HTTP
Right Answer:
GET is used to retrieve data from a server, POST is used to send data to a server to create a resource, PUT is used to update an existing resource on the server, and DELETE is used to remove a resource from the server.
Ques:- What is API documentation and why is it necessary
Right Answer:
API documentation is a technical manual that explains how to use an API, including its endpoints, request and response formats, authentication methods, and examples. It is necessary because it helps developers understand how to integrate and interact with the API effectively, ensuring proper usage and reducing errors.
Ques:- What is the difference between REST and SOAP APIs
Right Answer:
REST (Representational State Transfer) is an architectural style that uses standard HTTP methods and is typically more lightweight and easier to use, while SOAP (Simple Object Access Protocol) is a protocol that relies on XML for message format and has strict standards for security and transactions. REST is generally more flexible and faster, while SOAP is more suited for enterprise-level services requiring high security and reliability.
Ques:- What are the different types of APIs
Right Answer:
The different types of APIs are:

1. **Open APIs (Public APIs)** - Available to developers and third parties.
2. **Internal APIs (Private APIs)** - Used within an organization.
3. **Partner APIs** - Shared with specific business partners.
4. **Composite APIs** - Combine multiple endpoints into a single call.
5. **Web APIs** - Accessible over the internet using HTTP/HTTPS.
Ques:- How do you prioritize features or tasks in an Agile sprint
Right Answer:
We prioritize features or tasks in an Agile sprint using a combination of factors like business value, risk, effort/size, dependencies, and urgency. Product Owner usually leads this, using techniques like MoSCoW (Must have, Should have, Could have, Won't have) or story pointing, to ensure the most valuable items are tackled first.
Ques:- How do you measure success in an Agile project, both in terms of output and team health
Right Answer:
Success in Agile is measured by:

* **Output:** Delivering valuable, working software frequently; achieving the product vision; meeting business goals; customer satisfaction; and predictability (consistent delivery).
* **Team Health:** Team morale; continuous improvement (velocity trends, retrospectives leading to action); collaboration; self-organization; and sustainable pace.
Ques:- What is Agile methodology, and how does it differ from traditional project management approaches
Right Answer:
Agile is an iterative and incremental approach to project management that focuses on collaboration, flexibility, and customer satisfaction. Unlike traditional, sequential (waterfall) methods, Agile embraces change throughout the project lifecycle through short development cycles called sprints.
Ques:- How do you ensure that Agile processes are being followed consistently
Right Answer:
We ensure consistent Agile processes through:

* **Training and coaching:** Ensuring the team understands Agile principles and practices.
* **Regular audits and retrospectives:** Identifying deviations and areas for improvement.
* **Using tools and templates:** Standardizing processes and providing guidelines.
* **Defining clear roles and responsibilities:** Ensuring everyone knows their part in the process.
* **Promoting open communication and feedback:** Encouraging early detection of issues.
Ques:- Can you describe a time when an Agile project didn’t go as planned and how you handled it
Right Answer:
"In one project, we underestimated the complexity of integrating a new third-party API. This caused us to miss our sprint goal. To address this, we immediately re-estimated the remaining work, broke down the integration into smaller, more manageable tasks, and increased communication with the API vendor. We also temporarily shifted team focus to prioritize the integration, delaying a lower-priority feature for the next sprint. Finally, in the sprint retrospective, we implemented a better vetting process for third-party integrations to avoid similar issues in the future."
Ques:- What is the difference between windows authentication and mixed mode authentication in sql server?
Right Answer:
Windows authentication uses Active Directory credentials to verify users, while mixed mode authentication allows both Windows credentials and SQL Server credentials (username and password) for user access.
