Best Connection Option for Adding Computers to a Network Segment
Question
A network technician is adding a 10/100 switch with RJ45 connectors to the company network to accommodate new computers being added to a network segment.
There is no auto-MDIX port on the switch that needs to be connected to the existing switch on the segment.
Which of the following should the technician use to make the connection?
A.
An RG-59 cable with BNC connectors B.
A multi-mode fiber cable C.
A straight-through Cat5 UTP cable D.
A cable with TIA/EIA 568a and 568b on each end.
D.

D.
The correct answer is D. A cable with TIA/EIA 568a and 568b on each end.
Explanation:
In a network, devices need to communicate with each other using cables, and the type of cable used can affect the performance of the network. When connecting switches together, it is important to use the correct type of cable to ensure that the devices can communicate effectively.
In this scenario, the technician is adding a 10/100 switch with RJ45 connectors to an existing network segment, which suggests that the existing network is likely using Ethernet technology. The switch does not have auto-MDIX, which means that the technician will need to use a cable with specific pinouts to make the connection.
TIA/EIA 568a and 568b are standards that define the pinout configurations for Ethernet cables. These standards specify how the wires in the cable should be connected to the RJ45 connector on each end of the cable. Using a cable with TIA/EIA 568a and 568b on each end ensures that the pinouts are correct and allows for proper communication between the switches.
Option A, an RG-59 cable with BNC connectors, is a coaxial cable that was commonly used in older networks but is not suitable for connecting Ethernet switches.
Option B, a multi-mode fiber cable, is a high-speed cable that is typically used for long-distance connections or in data centers. It is not necessary or appropriate for connecting switches in a typical office environment.
Option C, a straight-through Cat5 UTP cable, is an Ethernet cable that is commonly used to connect devices to a network, but it is not suitable for connecting switches together because it does not have the correct pinout configuration.
Therefore, option D, a cable with TIA/EIA 568a and 568b on each end, is the correct choice for connecting the switches together in this scenario.
