220-1201 Practice Question: Run a new network cable from a patch panel to a…
A technician is asked to run a new network cable from a patch panel to a cubicle 80 meters away. The cable must support at least 1 Gbps. The technician has Cat6 cable on hand. What is the maximum distance this cable will support for 1 Gbps?
⚠ Common exam trap
In CompTIA A+ 220-1201, candidates often confuse the maximum distance for 1 Gbps (100 meters) with the distance for 10 Gbps over Cat6 (55 meters), mistakenly applying the shorter limit.

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
✓
100 meters
Cat6 cable is rated to support 1 Gbps Ethernet (1000BASE-T) up to a maximum distance of 100 meters per the TIA/EIA-568 standard. Since the required distance is 80 meters, which is within this limit, the cable will support 1 Gbps. The 100-meter limit includes the combined length of the horizontal cable from the patch panel to the cubicle, plus any patch cords at both ends.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
55 meters
Why it's wrong here
55 meters is the limit for 10 Gbps on Cat6, not 1 Gbps.
- ✓
100 meters
Why this is correct
Cat6 supports 1 Gbps up to 100 meters, so 80 meters is within spec.
- ✗
150 meters
Why it's wrong here
No twisted pair Ethernet standard supports 150 meters; the maximum is 100 meters.
- ✗
200 meters
Why it's wrong here
200 meters is beyond the limit for copper Ethernet; fiber would be needed for that distance.
