CompTIA ITF+ ITF Software Development 3 — Questions and Answers
Question 1: Which type of software testing is performed without knowledge of the internal code structure?
- White-box testing
- Unit testing
- Black-box testing (Correct answer)
- Regression testing
Correct answer: Black-box testing
Black-box testing evaluates software functionality without knowledge of the internal code, focusing only on inputs and outputs.
Question 2: What is the role of an Integrated Development Environment (IDE)?
- To deploy applications to servers
- To provide tools for writing, testing, and debugging code in one place (Correct answer)
- To manage network connections
- To design database schemas
Correct answer: To provide tools for writing, testing, and debugging code in one place
An IDE combines a code editor, debugger, and build tools into a single application to streamline software development.
Question 3: In object-oriented programming, what is a 'class'?
- A running instance of a program
- A blueprint for creating objects (Correct answer)
- A type of conditional statement
- A network protocol
Correct answer: A blueprint for creating objects
A class is a blueprint or template that defines the properties and behaviors shared by objects created from it.
Question 4: Which of the following describes an interpreted programming language?
- Code is converted entirely to machine code before execution
- Code is executed line-by-line at runtime by an interpreter (Correct answer)
- Code compiles directly to assembly language
- Code requires a virtual machine to compile
Correct answer: Code is executed line-by-line at runtime by an interpreter
Interpreted languages execute code line-by-line at runtime, which allows for easier testing but can be slower than compiled languages.
Question 5: What does the acronym 'API' stand for?
- Application Programming Interface (Correct answer)
- Automated Process Integration
- Applied Program Instruction
- Active Protocol Interface
Correct answer: Application Programming Interface
API stands for Application Programming Interface, which defines how software components communicate with each other.
Question 6: Which loop type in programming always executes its body at least once?
- for loop
- while loop
- do-while loop (Correct answer)
- foreach loop
Correct answer: do-while loop
A do-while loop executes its body first and then checks the condition, guaranteeing at least one execution.
Question 7: What is the main purpose of commenting code?
- To make the program run faster
- To encrypt sensitive logic
- To explain the purpose of code for human readers (Correct answer)
- To create executable documentation
Correct answer: To explain the purpose of code for human readers
Code comments are annotations that explain the purpose or logic of code sections, making it easier for developers to understand and maintain.
