Which VLAN number is typically associated with voice traffic?

VLANs are used to segment network traffic for various purposes, including isolating voice traffic from data traffic to improve performance and security. The commonly accepted VLAN number designated for voice traffic is VLAN 100. This specific number is often utilized in networking environments to ensure that voice packets receive the appropriate Quality of Service (QoS) treatment, thereby minimizing latency and ensuring clearer voice communications.

When VLAN 100 is configured for voice traffic, network devices are able to prioritize this traffic, which is crucial in environments where voice over IP (VoIP) is implemented. By isolating voice traffic, it ensures that it does not become negatively impacted by data traffic spikes, leading to better call quality and reliability.

The other choices do not traditionally correspond to voice traffic and may not be recognized by default configurations in many networking setups. Therefore, VLAN 100 is recognized as a standard choice for this specific application in voice networks.
