  1. Which software testing approach validates that the system meets specified business requirements from the end user's perspective?

    Answer: Black-box testing

    Black-box testing evaluates system behavior based solely on inputs and outputs without knowledge of the internal implementation.

  2. What does 'DRY' stand for in software development best practices?

    Answer: Don't Repeat Yourself

    DRY (Don't Repeat Yourself) is a principle that promotes reducing repetition by abstracting common logic into reusable components.

  3. Which of the following is a characteristic of a 'stateless' protocol like HTTP?

    Answer: Each request is independent and contains all information needed to process it

    In a stateless protocol, each request is self-contained and the server does not retain information between requests.

  4. In software development, what is 'technical debt'?

    Answer: The implied cost of rework caused by choosing a quick solution over a better long-term approach

    Technical debt represents the future cost of rework accumulated when developers choose expedient shortcuts over cleaner, more maintainable solutions.

  5. What is the key difference between a 'compiled' language and an 'interpreted' language?

    Answer: Compiled code is translated to machine code before execution; interpreted code is translated line-by-line at runtime

    Compiled languages translate the entire source code to machine code before execution, while interpreted languages translate and execute code line-by-line at runtime.

  6. Which design principle states that software entities should be open for extension but closed for modification?

    Answer: Open/Closed Principle

    The Open/Closed Principle states that you should be able to add new functionality by extending a class without modifying its existing code.

  7. What does 'exception handling' allow a program to do?

    Answer: Respond to error conditions gracefully without crashing

    Exception handling allows a program to detect, respond to, and recover from runtime errors in a controlled manner.
