FC0-U71 Practice Question: Which TWO of the following are primitive data…
Which TWO of the following are primitive data types commonly used in programming?
⚠ Common exam trap
A common pitfall is thinking String is a primitive because it looks simple, but in most languages it is a reference type with methods and internal state.
Answer choices

Correct answer & explanation
✓
Integer
Integer (B) is a primitive data type because it directly represents whole-number values in a single, indivisible unit that the language's compiler or interpreter handles natively, such as int in Java/C# or int/long in C. Boolean (C) is also primitive because it stores a single truth value (true or false) as a fundamental, built-in type with no internal structure, e.g., bool in C++/C# or boolean in Java. By contrast, String (A) is typically a composite/reference type built from characters (or a class such as java.lang.String), Array (D) is a derived/aggregate type that holds multiple elements of another type, and Function (E) is a callable construct (often a reference type or object), not a primitive data type.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
String
Why it's wrong here
String is a composite or reference type in most languages, not primitive; it is built from characters. It is tempting because strings appear alongside ints and booleans in declarations, but primitives are the built-in scalar types such as int, char, boolean and float.
- ✓
Integer
Why this is correct
Integer is a primitive type because the language stores the value directly rather than as a reference to an object. It satisfies the stem's requirement for a basic built-in data type, holding whole numbers without methods or properties.
- ✓
Boolean
Why this is correct
Boolean is primitive because it holds a single true or false value stored directly in memory, not as an object reference. This satisfies the stem's requirement for a fundamental built-in type used in conditional logic.
- ✗
Array
Why it's wrong here
An array is a composite or reference type holding multiple elements, not primitive. It is tempting because arrays are declared with type syntax, but primitives are scalar built-ins like int, char, boolean and float; arrays aggregate them.
- ✗
Function
Why it's wrong here
A function is executable code, not a data type at all, so it cannot be primitive. It is tempting because functions are declared and named like variables, but primitives describe values such as int, char, boolean and float, not callable routines.
