FC0-U71 Infrastructure Practice Question
A technician is configuring a new workstation for video editing. Which of the following expansion cards would be MOST beneficial for improving video rendering performance?
⚠ Common exam trap
FC0-U71 often tests the function of expansion cards — candidates may confuse a TV tuner card with a video capture or rendering card, but only a GPU accelerates video rendering performance.
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
✓
Graphics processing unit (GPU)
A Graphics Processing Unit (GPU) is specifically designed for parallel processing of graphics and video rendering tasks, making it the most beneficial expansion card for improving video rendering performance. Video editing and rendering workloads rely heavily on GPU acceleration for effects, encoding, and real-time preview. Adding a dedicated GPU offloads these tasks from the CPU and dramatically reduces render times.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
TV tuner card
Why it's wrong here
A TV tuner card receives and decodes broadcast television signals; it provides no rendering pipeline or GPU compute. It is tempting because video work involves video signals, but the correct choice is a dedicated graphics card, which offloads encoding and rendering from the CPU.
- ✗
Network Interface Card (NIC)
Why it's wrong here
A NIC provides network connectivity for transferring footage or uploading finished projects, but performs no rendering computation. It is tempting because editors often move large media files across networks, yet the correct choice is a graphics card, which supplies the GPU acceleration rendering depends on.
- ✓
Graphics processing unit (GPU)
Why this is correct
A discrete GPU offloads parallel rendering workloads from the CPU, dramatically accelerating video encoding and effects processing. Video editing software exploits GPU compute APIs such as CUDA, OpenCL or hardware encoders for this. This directly satisfies the stem's requirement for improved rendering performance, unlike sound, network or storage cards.
- ✗
Sound card
Why it's wrong here
A sound card handles audio input and output processing only, contributing nothing to video rendering or encoding workloads. It is tempting because video editing involves audio tracks, but the correct choice is a graphics card, whose GPU accelerates render and encode operations.

Variation 1. A technician is choosing expansion cards for a new workstation. The workstation will be used for high-end gaming and video editing. Which TWO cards are most essential for these tasks?
medium- A.Network interface card (NIC)
- B.TV tuner card
- ✓ C.Graphics card (GPU)
- ✓ D.Sound card
- E.USB expansion card
Why C: A dedicated GPU is essential for gaming and video editing, and a sound card provides high-quality audio.
