FC0-U71 Practice Question: Which TWO of the following are characteristics of…
Which TWO of the following are characteristics of object-oriented programming (OOP)?
⚠ Common exam trap
CompTIA often tests the distinction between OOP characteristics and general programming concepts, so candidates may mistakenly select 'Use of functions and procedures' (E) because they associate it with methods, but OOP's defining traits are encapsulation, inheritance, and polymorphism, not mere function usage.
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
✓
Inheritance
Inheritance (B) is a core characteristic of OOP because it allows a class to derive properties and behaviors from a parent class, promoting code reuse and establishing a hierarchical relationship. This is fundamental to OOP as defined in languages like Java, C++, and Python.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Polymorphism
Why it's wrong here
Polymorphism is also an OOP concept, but only two correct answers are required; we already have two.
- ✓
Inheritance
Why this is correct
Inheritance allows a class to derive from another class.
- ✗
Top-down design
Why it's wrong here
Top-down design is a structured programming approach, not an OOP characteristic.
- ✓
Encapsulation
Why this is correct
Encapsulation bundles data and methods together and hides internal state.
- ✗
Use of functions and procedures
Why it's wrong here
This is typical of procedural programming, not exclusive to OOP.
