Which condition would most likely lead to increased collisions in a network?

Adding more nodes to a network increases the number of devices that can communicate within that network segment. Each device connected to a shared medium has the potential to transmit data at the same time, which can lead to increased collisions, especially in networks that use collision domains, such as those operating on Ethernet technology.

In a scenario where multiple nodes try to transmit data simultaneously over a limited bandwidth, the chances of packets colliding as they traverse the network increase. When a collision occurs, both packets must be resent, which can introduce latency and reduce overall network efficiency. Therefore, as more nodes are added, the likelihood of these collisions occurring rises significantly, resulting in network congestion and reduced performance.

Other options, such as reducing the number of devices, increasing network bandwidth, and using fiber optics, generally aim to decrease the likelihood of collisions or improve the network's capacity to handle traffic instead of increasing it.
