Which of the following cable type would be used when directly connecting two servers?

A crossover cable is specifically designed to directly connect two devices of the same type, such as two computers, two servers, or two network switches, without the need for an intervening hub or switch. It achieves this by swapping the transmit and receive wire pairs at one end, allowing the transmit pins of one device to connect to the receive pins of the other.

A coaxial cable is used for different types of networking (e.g., older Ethernet, cable TV) and cannot be directly used to connect two servers with RJ45 Ethernet ports.

A rollover cable (or console cable) is used to connect a computer's serial port to a network device's console port for management and configuration purposes, not for direct data transfer between two servers.

A straight-through cable is used to connect dissimilar devices, such as a computer to a switch or a router to a switch, where the transmit and receive pins are already correctly aligned by the intervening network device.
