In which scenario would a switch be preferred over a hub?

A switch is preferred over a hub in scenarios where minimizing network data collisions is crucial due to the fundamental differences in how they operate. A hub functions as a basic networking device that broadcasts data packets to all devices connected to it, regardless of the intended recipient. This can result in a higher likelihood of data collisions as multiple devices attempt to send data simultaneously on the same network segment.

In contrast, a switch intelligently directs incoming data packets to the specific device for which they are intended. It does this by maintaining a MAC address table, which helps it route traffic more efficiently. By doing so, a switch minimizes the chances of collisions because each communication session can occur simultaneously without interfering with others. As a result, network performance improves considerably, and it becomes more efficient for devices to communicate without interruption.

The other scenarios do not inherently require the advantages provided by a switch:

• Advanced routing functions are typically handled by routers, not switches, which primarily manage traffic at a more localized, data link layer level.

• Wireless connections are managed by access points or routers and are not directly tied to whether a hub or switch is used.

• Simplifying network management tasks can involve various types of devices and configurations, and is not exclusively linked to the use of switches over hubs.
