Which cable type must be used when connecting two like devices together using these criteria? - Pins 1 to 3 and 2 to 6 are required. - Auto detection MDI-X is unavailable.

A straight-through cable connects devices with different pinout assignments (e.g., switch to router, host to switch) by maintaining the same pin configuration on both ends, which would lead to incorrect transmit/receive connections for like devices without MDI-X.

A console cable (rollover cable) is used to connect a computer's serial port to a network device's console port for management purposes, not for sending network traffic between network devices.

A crossover cable is specifically designed to connect like devices (e.g., switch to switch, host to host) by swapping the transmit (Tx) pins (1 and 2) on one end with the receive (Rx) pins (3 and 6) on the other end, which aligns with the 'Pins 1 to 3 and 2 to 6 are required' criteria. This is essential when Auto MDI-X is absent, as it prevents devices from automatically detecting and adjusting for cable type.

A rollover cable is another name for a console cable, used for out-of-band management of network devices, not for Ethernet data transmission between two network devices.
