FC0-U71 Tech Concepts and Terminology Practice Question
A help desk technician is setting up a new laptop for a remote employee. The employee needs to copy a 6 GB video file onto the laptop, which has a 256 GB solid-state drive. Which of the following storage interfaces would provide the fastest transfer speed for an external drive connected to this laptop?
⚠ Common exam trap
The trap here is assuming that any USB connection is equally fast, but USB 2.0 is much slower than USB 3.2 Gen 2.
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
✓
USB 3.2 Gen 2
USB 3.2 Gen 2 delivers up to 10 Gbps, making it the fastest among the listed interfaces. For transferring a large 6 GB video file, speed is critical. USB 2.0, eSATA, and FireWire 800 are all slower and less practical for modern laptops. Therefore, USB 3.2 Gen 2 is the best choice.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
FireWire 800
Why it's wrong here
FireWire 800 provides up to 800 Mbps, which is slower than USB 3.2 Gen 2 and even USB 2.0 in some cases. It is an older interface rarely found on current laptops. Thus, it would not offer the fastest transfer speed for the video file.
- ✗
USB 2.0
Why it's wrong here
USB 2.0 has a maximum transfer rate of 480 Mbps, which is significantly slower than USB 3.2 Gen 2. Copying a 6 GB file over USB 2.0 would take several minutes, while USB 3.2 Gen 2 would complete it much faster. Therefore, USB 2.0 is not the fastest option for this task.
- ✓
USB 3.2 Gen 2
Why this is correct
USB 3.2 Gen 2 supports up to 10 Gbps, making it the fastest option listed for an external drive. It is commonly available on modern laptops and is ideal for transferring large files like a 6 GB video. The other interfaces are slower, so USB 3.2 Gen 2 provides the best performance for this scenario.
- ✗
eSATA
Why it's wrong here
eSATA offers up to 3 Gbps, which is faster than USB 2.0 but slower than USB 3.2 Gen 2. It is also less common on modern laptops, often requiring an adapter. For a 6 GB file transfer, USB 3.2 Gen 2 would still be faster and more convenient.
