What VPN setting would increase bandwidth utilization during remote meetings on a multicast teleconference system?

1. Split tunneling is disabled

2. Low bandwidth mode enabled

3. Traffic compression enabled

4. Quality of Service enabled

The correct answer is: Split tunneling is disabled

The correct answer relates to the impact of split tunneling on bandwidth utilization during remote meetings using a multicast teleconference system. When split tunneling is disabled, all traffic from the user's device is routed through the VPN. This means that data packets related to the teleconference – which could be substantial in size – utilize the entire bandwidth available through the VPN connection. By routing all traffic through the VPN, it can potentially lessen the chance of packet loss and improve the overall quality of the multicast by ensuring that enough bandwidth is allocated for the meeting traffic. In a multicast environment, this is particularly important as video and audio streams can benefit from the stable connection that comes from having all traffic tunneled through the VPN. The other options do not directly address increasing bandwidth utilization effectively during remote meetings. Low bandwidth mode typically aims to reduce the amount of data being transmitted, which could affect quality. Traffic compression reduces the size of the data packets, which may not appropriately address the needs of high-quality video and audio streams in real-time communication. Quality of Service (QoS) can prioritize teleconference data over other types of traffic, but it does not inherently increase the overall bandwidth available; it simply manages how that bandwidth is utilized among different applications.
