FC0-U71 Tech Concepts and Terminology Practice Question
Which of the following is the binary result of the AND operation on 1010 and 1110?
⚠ Common exam trap
FC0-U71 often tests the difference between bitwise AND and OR operations, causing candidates to mistakenly apply OR logic and select 1110.

Correct answer & explanation
✓
1010
The AND operation compares each bit of two binary numbers and returns 1 only if both bits are 1. For 1010 and 1110: 1 AND 1 = 1, 0 AND 1 = 0, 1 AND 1 = 1, 0 AND 0 = 0, resulting in 1010. Thus, option B is correct.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
1011
Why it's wrong here
Bitwise AND yields 1 only where both operands hold 1; 1010 AND 1110 gives 1010, not 1011. It tempts because 1011 resembles the operands and could result from OR (1110) or careless column work, but AND requires matching 1s in every position.
- ✓
1010
Why this is correct
Bitwise AND compares each column: 1 AND 1 gives 1, 0 AND 1 gives 0, 1 AND 1 gives 1, 0 AND 0 gives 0. Reading the results left to right yields 1010, matching the option exactly.
- ✗
0010
Why it's wrong here
AND on 1010 and 1110 produces 1010; 0010 would require the first and third bits to be 0, which they are not. It tempts as a plausible low-value result, but it actually matches neither AND nor OR of these operands.
- ✗
1110
Why it's wrong here
Bitwise AND yields 1010: each column is true only where both operands hold 1, and the second bit of 1010 is 0. 1110 is the OR result, which is tempting because OR returns 1 wherever either operand does.
