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
✓
AND
AND and XOR are standard binary operations; NOT is unary; OR is included but only TWO must be selected. The correct ones are AND and XOR.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
NOT
Why it's wrong here
NOT is a unary operation, not binary (operates on single input).
- ✓
AND
Why this is correct
AND is a valid binary operation.
- ✗
SUBTRACT
Why it's wrong here
Subtraction is an arithmetic operation, but not typically considered a 'binary operation' in the context of bitwise logic.
- ✗
DIVIDE
Why it's wrong here
Division is arithmetic, not a binary logic operation.
- ✓
XOR
Why this is correct
XOR is a valid binary operation.

Same concept, more angles
1 more way this is tested on FC0-U71
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. An IT instructor is teaching about binary arithmetic operations. Which TWO of the following are correct results of a logical XOR operation on the binary inputs 1 and 0? (Select TWO.)
medium- A.1 XOR 0 = 0
- ✓ B.0 XOR 1 = 1
- C.1 XOR 1 = 1
- ✓ D.1 XOR 0 = 1
- E.0 XOR 1 = 0
Why B: XOR outputs 1 when inputs differ. 1 XOR 0 = 1. Also, 0 XOR 1 = 1. So both pairs produce 1.
