FC0-U71 Infrastructure Practice Question
A home user has a laptop with an integrated webcam that no longer works after a recent driver update. The user needs a quick, low-cost replacement for video calls. Which of the following should the technician recommend?
⚠ Common exam trap
Many candidates confuse video capture or docking hardware with a camera, when only a device with an integrated image sensor can replace a broken webcam.
Answer choices

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A USB webcam
An external USB webcam is the simplest and least expensive way to restore video calling when an integrated camera fails. It connects to an available USB port, is recognized by common operating systems, and does not require disassembly or specialized drivers. The other options either do not provide a camera or are intended for different purposes entirely.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
A KVM switch
Why it's wrong here
A KVM switch lets one keyboard, monitor, and mouse control multiple computers. It has no camera or video capture capability, so it cannot replace a broken webcam. Using it would not address the user's need to participate in video calls, and it introduces extra cabling without solving the underlying hardware failure.
- ✓
A USB webcam
Why this is correct
A USB webcam is an external peripheral that connects through the USB port and provides immediate video capture without opening the laptop, which is ideal for a quick, low-cost replacement. It bypasses the failed integrated webcam entirely and usually works with built-in operating system drivers, so the user can resume video calls with minimal setup.
- ✗
A PCIe video capture card
Why it's wrong here
A PCIe video capture card is an internal expansion card installed in a desktop motherboard slot, not in a typical laptop. It captures video from external sources rather than acting as a camera, so it would not restore webcam functionality. Installing it would also require opening the system, which contradicts the need for a quick, low-cost fix.
- ✗
A Thunderbolt docking station
Why it's wrong here
A Thunderbolt docking station expands ports and may support displays and peripherals, but it does not contain a camera. It would not replace the failed integrated webcam or provide video capture for calls. It is also more expensive than a simple external camera and adds unnecessary complexity for this specific problem.
