What issue does a broadcast storm typically cause in a network?

A broadcast storm occurs when there is an excessive level of broadcast traffic on a network, which can significantly disrupt the normal functioning of network operations. In a broadcast storm, devices on the network continuously send broadcast packets, leading to an overwhelming amount of traffic that can saturate the network. When this happens, legitimate network communications are hindered, creating severe congestion.

The severe network congestion caused by a broadcast storm can lead to a number of issues, including slowed network speeds, dropped packets, and difficulties for devices in communicating with one another. This congestion impacts all users on the network and can severely degrade performance, making it difficult for even basic tasks to function properly. Solutions to mitigate broadcast storms include configuring switch port settings to limit broadcast traffic and using protocols that help manage and minimize unnecessary broadcasts.

The other options reflect positive outcomes or concepts that are not relevant to the impact of a broadcast storm. Improved routing efficiency, enhanced network security, and increased data integrity are not issues associated with broadcast storms; rather, those may be goals or benefits in typical network design and maintenance practices.
