Actual exam question from CompTIA's N10-008

Question #: 441
Topic #: 1

A network technician is troubleshooting a network issue for employees who have reported issues with speed when accessing a server in another subnet. The server is in another building that is 410ft (125m) away from the employees' building. The 10GBASE-T connection between the two buildings uses Cat 5e. Which of the following BEST explains the speed issue?

A. The connection type is not rated for that distance.
B. A broadcast storm is occurring on the subnet.
C. The cable run has interference on it.
D. The connection should be made using a Cat 6 cable.

Using compTIA logic (they hint oddly specific 125m) the issue is that this is wrong "connection type". Sounds weird, but cat6 doesn't solve anything & nothing points to interference or broadcast storm.

True. And Cat 6 is 10GBASE-T at 55 meter, while "Cat 6a" is 100 meters. But still 125m for cable length is too long, that's why A. is the answer.

so I guess you would use a fiber optic cable?

"Using Cat 5e cabling for a 10GBASE-T connection over a distance of 410ft (125m) is beyond the recommended distance limit and can result in significant signal degradation and slow network speeds."

It doesn't ask to specify in the question, but could someone elaborate on what would be the best solution for this issue? Would you simply use a signal extender/repeater and 2 cables, neither extending past 328 feet?

I would think to install a repeater? But you can imagine how that would be troublesome, now you have another device in the middle that needs maintaining and maybe cannot be left alone for as long as a cable can be. I don't know if that is the best solution though, I'm also still learning.

Multimode fiber cable. It goes less than 400 m ( 1300 feet )

Using fiber after 100meters(328ft) is standard practice, instead of copper.

A. The connection type is not rated for that distance. 10GBASE-T is a type of Ethernet standard that supports data transfer rates up to 10 Gbps over twisted-pair copper cabling. However, the maximum distance supported by 10GBASE-T over Cat 5e cabling is 328 feet (100 meters). In this scenario, the distance between the two buildings is 410 feet (125 meters), which exceeds the maximum distance limit for 10GBASE-T over Cat 5e cabling.

10GBASE-T is Cat 6 not Cat 5e which is for 1000BASE-T

Even if you use Cat6, it would not resolve the issue. The distance is just too far.
