This FC0-U61 practice question tests your understanding of it concepts and terminology. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which TWO of the following are input devices? (Select two.)
Printer
Why wrong: A printer produces output on paper.
Mouse
A mouse provides input through movement and clicks.
Monitor
Why wrong: A monitor is an output device.
Speaker
Why wrong: Speakers output sound.
Keyboard
A keyboard sends input to the computer.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Mouse
A mouse is an input device because it captures physical movement and button clicks, converting them into digital signals that the computer interprets to control the cursor or execute commands. It sends data to the system rather than receiving or outputting information, which is the defining characteristic of an input device.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.

Common exam traps
The trap here is that candidates often confuse 'peripheral devices' with 'input devices,' mistakenly selecting output-only peripherals like printers or monitors because they are commonly connected to a computer, but the question specifically tests the direction of data flow.
Trap categories for this question
Command / output trap
A printer produces output on paper.
Detailed technical explanation
Input devices like mice use protocols such as USB HID (Human Interface Device) class to communicate movement and button states to the operating system, which then processes these events via interrupt handlers. In contrast, output devices like monitors rely on display standards (e.g., VGA, DVI, HDMI) to receive pixel data from the GPU. A real-world scenario where this distinction matters is in kiosk systems: a touchscreen combines both input and output functions, but each function uses separate hardware and driver layers.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the FC0-U61 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
