Which medium is the most common choice for a 10G uplink between wiring closets on different floors of the same building?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
Distractor review
Rollover cable
A rollover cable is for console access, not uplinks.
Best answer
Fiber optic cable
Correct. Fiber is the standard uplink choice here.
Distractor review
Coaxial cable
Coax is not the normal modern enterprise uplink medium in this scenario.
Distractor review
Console cable
A console cable is for management access, not switching uplinks.
Common exam trap
Common exam trap: answer the scenario, not the keyword
{"title":"Cat6 vs. Fiber Backbones","description":"While Cat6a can support 10G, Cisco's 'Best Practice' answer for floor-to-floor vertical runs is almost always fiber."}
Technical deep dive
How to think about this question
Treat this as a scenario question. Identify the problem, the constraint, and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Fiber optic cables use light signals to transmit data, enabling high bandwidth and long-distance connections ideal for 10G Ethernet uplinks between building floors.
- Copper cables like Cat6a can support 10G speeds but only up to 100 meters, making them less suitable than fiber for inter-floor uplinks in enterprise networks.
- Console and rollover cables are designed for device management and configuration access, not for carrying network traffic between switches or routers.
- Coaxial cables are largely obsolete for modern Ethernet networks and do not support 10G speeds or typical enterprise uplink requirements.
- Cisco networking best practices recommend fiber optic cables for uplinks between wiring closets to ensure reliable, high-speed connectivity with minimal interference.
- Choosing the correct uplink medium requires understanding physical layer characteristics such as bandwidth, distance limitations, and electromagnetic interference resistance.
- Fiber optic cables future-proof network infrastructure by supporting higher speeds and longer distances, aligning with scalable enterprise campus designs.
- Exam questions often test knowledge of cable purposes; distinguishing management cables from data transport cables is critical to avoid common mistakes.
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.

FAQ
Questions learners often ask
What does this 200-301 question test?
Fiber optic cables use light signals to transmit data, enabling high bandwidth and long-distance connections ideal for 10G Ethernet uplinks between building floors.
What is the correct answer to this question?
The correct answer is: Fiber optic cable — Fiber is commonly used for building uplinks because it supports higher bandwidth and longer distances than typical copper for this use case.
