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
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Integer
Integer and Boolean are primitive data types because they represent single, indivisible values directly supported by the hardware and language runtime. An Integer stores whole numbers (e.g., 42), while a Boolean stores true/false values. These are fundamental building blocks that are not composed of other data types.
