How does implementing VLAN configurations impact broadcast traffic?

Implementing VLAN configurations significantly helps to contain broadcast traffic within specific segments. VLANs, or Virtual Local Area Networks, create separate logical networks within the same physical network infrastructure. When devices are grouped into different VLANs, broadcasts sent by a device in one VLAN are confined to that VLAN and do not cross over to other VLANs.

This containment of broadcast traffic reduces unnecessary load on other segments of the network, improving overall network performance and efficiency. Each VLAN acts as an independent broadcast domain, meaning that broadcast messages (like ARP requests) are only sent to devices within the same VLAN, minimizing the impact on other segments and reducing the likelihood of broadcast storms.

The other options relate to different aspects of networking but do not accurately describe the fundamental effect VLANs have on broadcast traffic. For example, while VLANs do not eliminate higher layers of network traffic, they directly influence the scope of broadcast traffic, making option B the correct choice. Additionally, they do not facilitate easier integration of IoT devices specifically, as this depends on various other factors, including network design and device compatibility.
