FC0-U71 Practice Question: A network technician is explaining to a client…
A network technician is explaining to a client why a file transfer over the network is slower than expected. Which factor MOST likely affects transfer speed?
⚠ Common exam trap
CompTIA often tests the misconception that encryption or file format directly controls transfer speed, when in fact bandwidth is the primary bottleneck in most network file transfers.
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
✓
Bandwidth
Bandwidth is the maximum rate at which data can be transferred over a network path, typically measured in bits per second (bps). A lower bandwidth directly limits the throughput of a file transfer, causing it to take longer regardless of other factors. This is the most fundamental constraint on transfer speed, as it defines the pipe size through which all data must flow.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Bandwidth
Why this is correct
Bandwidth is the maximum data transfer rate and directly affects speed.
- ✗
File compression
Why it's wrong here
Compression can speed up transfers but is not the primary factor.
- ✗
File format
Why it's wrong here
File format affects size but not the transfer rate itself.
- ✗
Encryption
Why it's wrong here
Encryption adds overhead but typically not the main cause of slowness.
