A software feature has already been released. Developers observe that users are struggling with the interface on a specific browser and release a patch to fix it. This activity belongs to which phase?

Two developers are working on different modules of an e-commerce system. One developer modifies a function’s parameters, causing the other developer’s code to break. Which concept would have helped prevent this issue?

Before releasing a banking application, the development team tests individual functions such as “check balance” and “transfer money” in complete isolation. What type of testing is being performed?

A student team begins coding a project immediately after an informal discussion with users. After completion, they repeatedly modify the code to fix mismatches with user expectations. This approach is best described as:

A software team wants to collect answers to specific, well-defined questions from thousands of geographically distributed sellers. Which requirement-gathering technique is most appropriate?

Which of the following is a correct user story template as per BDD?

An e-commerce website allows returning customers to purchase items quickly by saving delivery addresses and payment details. This design primarily improves:

Multiple screens of a mobile application are drawn on paper, and switching between screens is simulated manually during discussions with users. Which prototyping technique is being used?

An e-commerce website allows users to browse products and check prices without requiring them to log in. Which heuristic for action does this design decision support?

A project has an initial COCOMO effort estimate of 20 person-months. After considering cost drivers, the Effort Adjustment Factor (EAF) is 1.5. What is the final estimated effort?

A person ensures that the development team delivers maximum value to the client and prioritizes work considering business needs and technical constraints. Which Scrum role is being described?

A team completes 4 story points in one sprint. This value is used to predict future progress. What is this value called?

Several developers with critical expertise leave the organization midway through a project, causing delays. Which mitigation strategy BEST addresses this risk?

A module performs a sequence of operations where each step depends on the previous one, but all steps contribute to one main goal. This is an example of:

If class Book inherits from class Product, which statement is true?

Which UML diagram is used to model message exchanges over time among objects?

A developer designs a [[IMAGE:6ac2f983e81be909_7_2]] class with private data like [[IMAGE:6ac2f983e81be909_7_3]] and [[IMAGE:6ac2f983e81be909_7_4]] , and allows access only through methods such as [[IMAGE:6ac2f983e81be909_7_5]] and [[IMAGE:6ac2f983e81be909_7_6]] . This describes which of the following object-oriented programming concepts?

A team of 20 developers is working on a large web application. One developer commits faulty code to the main branch that crashes the system. Other developers are unable to test their own changes. The team wants to quickly revert to a stable version and identify who made the faulty change. Which feature of a Version Control System directly addresses this situation?

A banking application calculates interest. Due to a wrong formula in the code, the system produces an incorrect interest amount for customers. In the same banking application, the developer finds that the line [[IMAGE:6ac2f983e81be909_8_7]] was written instead of [[IMAGE:6ac2f983e81be909_8_8]] This incorrect line is an example of:

A video-streaming application is functionally correct, but users complain that it is very slow when playing high-resolution videos. The development team wants to find out: • Which functions consume the most CPU time • Where memory usage is highest • Which parts of the program are performance bottlenecks Which debugging tool or technique should the team use?

A photo-editing application applies a series of transformations to an image: first resizing, then filtering, then compression, and finally saving it to disk. Each stage takes input from the previous stage and passes output to the next. Which architecture best represents this system?

An e-commerce system performs the following steps when a customer places an order: 1. Create an Order 2. Notify the Seller 3. Call Packaging 4. Call Delivery Originally, every client had to call all these classes in the correct sequence. To simplify this, a new class [[IMAGE:6ac2f983e81be909_9_9]] was created with a method: [[IMAGE:6ac2f983e81be909_9_10]] This method internally creates all required objects and executes all steps in order. Which design pattern is being used?

A software company builds a system to process both physical books and e-books. The interface [[IMAGE:6ac2f983e81be909_9_11]] contains the following methods: • [[IMAGE:6ac2f983e81be909_9_12]] • [[IMAGE:6ac2f983e81be909_9_13]] • [[IMAGE:6ac2f983e81be909_9_14]] • [[IMAGE:6ac2f983e81be909_9_15]] The e-book module must implement [[IMAGE:6ac2f983e81be909_10_16]] and [[IMAGE:6ac2f983e81be909_10_17]] even though they do nothing. Which principle is violated?

Which of the following are non-functional requirements? (Select all that apply)

Which of the following are characteristics of heuristic (model-based) estimation techniques? (Select all that apply)
