What does Auto-MDIX do?

What does Auto-MDIX do?

• A. It automatically adjusts the NIC to accommodate straight-through or cross-over cables.
• B. It enforces data integrity in frames.
• C. It assigns IP addresses automatically.
• D. It negotiates speed automatically.

Answer: (A)

Auto-MDIX automatically detects whether the connected cable is straight-through or crossover and reconfigures the interface so the transmit and receive pairs are correctly matched. This lets devices communicate without you having to choose the cable type, reducing setup mistakes and making plug-and-play connections smoother. It doesn’t handle data integrity, IP address assignment, or speed negotiation—those are separate functions.
