Which statement is true about the auto-MDIX feature on a switch?

• A. It requires manual configuration of the cable type.
• B. It operates only with crossover cables.
• C. It automatically configures the interface for straight-through or crossover connections.
• D. It disables the switch's ability to negotiate speeds.

Answer: (C)

The statement that auto-MDIX automatically configures the interface for straight-through or crossover connections is accurate because the auto-MDIX feature on a switch enables it to detect the type of cable (whether it's straight-through or crossover) being used to connect to another device. When a device is connected, the switch can automatically adjust its configuration to ensure proper communication without the need for manual configuration. This capability is particularly useful because it simplifies the setup process and reduces potential errors related to cable type selection, allowing for greater flexibility in installation and reducing the complexity of network management. In contrast, the other statements do not reflect the functionality of auto-MDIX accurately. The feature is designed precisely to eliminate the need for manual configuration of the cable type and operates automatically, adapting to the connection type as required. It does not solely work with crossover cables since it supports both cable types transparently. Furthermore, it maintains negotiation capabilities for speeds, so the assertion that it disables speed negotiation is also incorrect.
