Which feature of a switch enhances network performance by reducing collisions?

• A. Full-duplex mode
• B. Half-duplex mode
• C. Broadcast domains
• D. Static routing

Answer: (A)

The feature that enhances network performance by reducing collisions is full-duplex mode. In full-duplex mode, a switch can send and receive data simultaneously on the same interface. This capability eliminates the possibility of collisions that occur in half-duplex mode, where data transmission can only occur in one direction at a time. By allowing two-way communication, full-duplex mode significantly improves the efficiency of data transmission and overall network performance. In contrast, the other options do not contribute to reducing collisions in the same way. Half-duplex mode inherently allows only one direction of communication at a time, which can lead to collisions when devices attempt to send data simultaneously. Broadcast domains refer to logical segmentation of a network, which helps manage traffic but does not directly influence collision reduction. Static routing concerns the management of network paths rather than the operation of individual switch interfaces, thus not directly affecting collision outcomes.
