FC0-U71 Practice Question: Which TWO of the following are examples of input…
Which TWO of the following are examples of input devices? (Select TWO).
⚠ Common exam trap
Test-takers frequently confuse the direction of data flow, mistakenly thinking that devices like printers or monitors can also accept user input (e.g., via touchscreens or control panels), but in their standard definition as peripherals, they are classified strictly as output devices unless specified otherwise.

Correct answer & explanation
✓
Mouse
The mouse and keyboard are classic examples of input devices because they allow users to send data and commands to a computer. A mouse translates physical movement and button clicks into cursor control signals, while a keyboard converts key presses into electrical signals that the system interprets as characters or commands. Both operate by sending input to the computer for processing, not by receiving or outputting data.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Printer
Why it's wrong here
A printer receives data from the computer and produces hard copy, so the signal direction is outward, not inward. It is tempting because printers are standard peripherals listed with scanners, which are genuine input devices; a printer would be correct only when classifying output devices.
- ✗
Speaker
Why it's wrong here
A speaker outputs audio, so data flows away from the computer rather than into it, failing the input-device requirement. It is tempting because speakers are common peripherals and appear in the same hardware lists as microphones, which are genuine input devices; speakers would be correct only when classifying output devices.
- ✗
Monitor
Why it's wrong here
A monitor renders visual output from the system, so it cannot supply data to the computer as an input device requires. It is tempting because monitors sit alongside keyboards and mice at every workstation, and touchscreen monitors do accept input; a plain monitor would be correct only when classifying output devices.
- ✓
Mouse
Why this is correct
A mouse translates physical hand movement into digital cursor coordinates and click events, feeding data into the computer for processing. This satisfies the stem's requirement for an input device, since input hardware sends commands or data to the system rather than receiving output from it.
- ✓
Keyboard
Why this is correct
A keyboard satisfies the input-device requirement because it converts physical keystrokes into digital signals that the computer processes as data. Unlike output devices, which present processed results to the user, the keyboard only sends data inward. This matches the stem's constraint of identifying hardware that feeds information into a system.

Same concept, more angles
2 more ways 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. Which of the following is an example of an input device?
easy- A.Printer
- B.Monitor
- ✓ C.Keyboard
- D.Speaker
Why C: A keyboard is an input device because it allows users to send data and commands to a computer by pressing keys, which are converted into electrical signals that the system processes. Input devices are defined as hardware components that provide data and control signals to a computer, and the keyboard is a classic example of this category.
Variation 2. Which of the following is an input device?
easy- A.Monitor
- ✓ B.Keyboard
- C.Printer
- D.Speaker
Why B: A keyboard is an input device because it sends data (keystrokes) into the computer for processing. Input devices convert human actions into signals the system can interpret, and the keyboard is the canonical example. Monitors, printers, and speakers all receive output from the computer rather than sending data in.
