Which condition would likely increase the amount of traffic across a network?

The condition that would likely increase the amount of traffic across a network is when many devices are syncing data. This process typically involves a significant exchange of information as each connected device updates itself with the latest data from the cloud or local servers. As multiple devices initiate sync operations simultaneously, the collective data transfer can lead to a considerable increase in network traffic.

Data syncing often involves uploading or downloading files, application updates, emails, and more, which can create substantial load on network bandwidth. The nature of syncing means that it generates continuous traffic as devices constantly communicate to ensure data consistency.

In contrast, while frequent software updates, high-quality video streaming, and regular scheduled backups can also generate traffic, the overall impact of many devices syncing simultaneously tends to create a more sustained and widespread increase in network utilization, particularly in environments with numerous connected devices.
