A network technician is terminating a custom twisted-pair Ethernet cable to connect two legacy network switches that do not support Auto-MDIX. The technician wires one RJ45 connector using the T568A standard and the other connector using the T568B standard. Which of the following best describes the cable type created and its function in this scenario?
- It creates a crossover cable, which allows direct communication between the two switches.Cevap
- BIt creates a straight-through cable, which is required for connecting similar networking devices.
- CIt creates a rollover cable, which is used exclusively to establish a serial console session.
- DIt creates an invalid cable wiring, which causes short circuits and damages the physical switch interfaces.
Cevap
Wiring T568A on one end and T568B on the opposite end produces an Ethernet crossover cable, which allows direct communication between similar network devices like switches when Auto-MDIX is unavailable.
Terminating one end of a UTP cable using T568A and the opposite end using T568B swaps the transmit and receive conductor pairs (pins 1/2 and pins 3/6). This creates an Ethernet crossover cable, which is designed to connect like devices (such as switch-to-switch or host-to-host) when automatic medium-dependent interface crossover (Auto-MDIX) is not supported by the network ports.
