C) The system must include a user-friendly interface for adding new entries
D) The system must store and retrieve customer data from the database
Which of the following best describes “stakeholder analysis” in the SDLC?
A) A process to identify and evaluate the key individuals or groups affected by the system and their interests
B) A method for testing the system to ensure it performs as expected
C) A technique used to define the system’s hardware and software requirements
D) A method for ensuring that the system meets business objectives and user expectations
Which of the following is the most important factor to consider during the “feasibility study” phase of SDLC?

Which type of testing is primarily concerned with evaluating how the system behaves under stress or heavy load conditions?
A) Functional Testing
B) Regression Testing
C) Load Testing
D) User Acceptance Testing (UAT)
In the context of system development, what does “scalability” refer to?
A) The ability to make changes to the system as requirements evolve
B) The ability of the system to handle increased load or traffic as it grows
C) The ease with which the system can be deployed across different environments
D) The system’s ability to meet user interface and aesthetic preferences
What does “iterative development” mean in the context of agile methodologies?
A) Developing the system in one large release after a long development cycle
B) Creating the system in small, manageable parts and revising them based on user feedback
