A network technician is connecting legacy network devices in a lab environment where Auto-MDIX is explicitly disabled on all switch interfaces. Which two statements correctly describe the cable pinout requirements and cabling types for these connections? (Choose two.)
- Connecting two network switches directly via FastEthernet interfaces requires a crossover cable when Auto-MDIX is disabled.Answer
- An Ethernet crossover cable connects transmit pins 1 and 2 on one RJ-45 connector to receive pins 3 and 6 on the opposite connector.Answer
- CConnecting a switch port directly to a router Ethernet interface requires a crossover cable when Auto-MDIX is disabled.
- DA standard straight-through Ethernet cable maps pins 1 and 2 on one end to pins 3 and 6 on the opposite end.
- EA rollover cable must be used to connect two Ethernet switches together for standard data transmission.
Answer
Connecting two network switches directly via FastEthernet interfaces requires a crossover cable when Auto-MDIX is disabled, and an Ethernet crossover cable connects transmit pins 1 and 2 on one RJ-45 connector to receive pins 3 and 6 on the opposite connector.
When connecting identical network device types (such as switch-to-switch or router-to-router) without Auto-MDIX feature active, a crossover cable must be used so that the transmit pins (1 and 2) on one end link to the receive pins (3 and 6) on the opposite end.
