- A
Cat6a copper cable
Why wrong: Copper Ethernet is limited to 100 meters for 10 Gbps, so 200 meters would require a repeater or switch.
- B
Fiber optic cable
Fiber supports distances over 200 meters easily, often up to kilometers, and is immune to EMI.
- C
Coaxial cable
Why wrong: Coaxial can go longer distances than copper but is typically used for cable TV/internet, not standard Ethernet.
- D
Wireless bridge
Why wrong: Wireless can work, but it may be less reliable and slower than fiber, and requires line of sight.

220-1201 Cabling Practice Question
This 220-1201 practice question tests your understanding of cabling. Compare every option against the stated constraints before choosing — the best answer satisfies all requirements, not just the most obvious one. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A customer wants to connect two buildings that are 200 meters apart with a high-speed network link. Which cabling solution is most appropriate?
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
✓
Fiber optic cable
Fiber optic cable is the most appropriate solution for connecting two buildings 200 meters apart because it supports high-speed data transmission over long distances without signal degradation. Unlike copper cables, fiber is immune to electromagnetic interference (EMI) and can easily exceed the 100-meter distance limit of twisted-pair cabling, making it ideal for inter-building links.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Cat6a copper cable
Why it's wrong here
Copper Ethernet is limited to 100 meters for 10 Gbps, so 200 meters would require a repeater or switch.
- ✓
Fiber optic cable

Wireless bridge
Why it's wrong here
Wireless can work, but it may be less reliable and slower than fiber, and requires line of sight.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often choose Cat6a copper cable (Option A) because they overlook the 100-meter distance limitation for twisted-pair Ethernet, assuming higher category cables can magically extend the range.
Detailed technical explanation
How to think about this question
Fiber optic cabling uses light pulses transmitted through glass or plastic cores, allowing distances up to several kilometers with single-mode fiber (SMF) or up to 550 meters with multimode fiber (OM4) at 10 Gbps. In real-world scenarios, fiber is often chosen for campus networks to avoid grounding issues between buildings and to provide future-proofing for higher speeds like 40 Gbps or 100 Gbps using wavelength-division multiplexing (WDM).
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 220-1201 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
