Software Engineering — DU B.Sc. (Hons) Computer Science Previous Year Question Papers

: B. Tech. CSE 1.(a) 1.(b) A medical startup is developing a high-stakes, robotic surgical assistant. Identify which one of the Waterfall, Spiral, and V&V models is most suitable for this project. Justify your choice by writing one specific advantage of the chosen model and one major limitation of each of the other two models in this specific context. [PO2, PO3] During development, a team working in Scrum model, encounters a major technical roadblock: the DatabaseSync feature is significantly more complex than the initial requirements suggested, making the current Sprint goal unattainable. How does a traditional model and an Agile model differ in their approach to handling such a technical discovery? [PO1] You are designing a Weather Monitoring System where a Sensor Data Component must communicate with a User Dashboard Component via an API. To ensure the system is maintainable and scalable, you must apply standard interface design principles. Identify whether Synchronous or Asynchronous communication is better suited for a scenario where the sensor sends updates every second. Justify your choice based on system performance. [PO1] A Smart Cafeteria system allows Students to order meals. The system must also interface with an external Bank API to process payments and allow a Kitchen Staff member to update the menu. For the "Order Meal" use case, write a single User Story in the format “As a …., I want… so that…”. [PO4] You are tasked with testing a new AI-driven Recommendation Engine. Between Black-box and White-box testing, which strategy is more appropriate for validating the final recommendations of this engine? Justify, in under two lines, your choice. [PO12] During the development of a high-performance database engine, your engineering team identifies a critical technical risk: the third-party compression library you planned to use may not meet the required data throughput speeds under heavy load. How the team would go about if it implements Risk Mitigation strategy. [PO1] An aerospace company is commissioned to develop a Flight Control System for a new commercial aircraft. The project is characterized by extremely high complexity, zero tolerance for failure, and requirements that are 100% fixed by international aviation authorities before development begins. However, the related hardware is being developed simultaneously with the software and may experience slight delays. I. How does the Waterfall model's lack of overlapping phases complicate the problem due to simultaneous development of hardware and software? II. How can the team adapt the pure Waterfall approach such that the stringent requirements, integration of hardware and software, and the development restrictions are met? [PO2] (3+6=9) You are the Lead Architect for a startup developing an Autonomous Drone Delivery
