Why would you use Isolated Subnets specifically for VPN clients?

Using isolated subnets for VPN clients is particularly important due to the nature of WAN connections, which can introduce greater latency compared to local area network (LAN) connections. When VPN clients connect through a WAN, they are often accessing resources that might be far away from their physical locations, resulting in delays that can affect performance. Isolating these subnets can help to optimize network management and enhance the performance of connections, as it simplifies the routing of traffic and allows for specific policies to be applied more effectively.

This configuration also allows for improved security measures to be implemented, as VPN clients might require distinct access controls and monitoring compared to local devices. By placing VPN clients in isolated subnets, it helps in managing the traffic more efficiently, especially under conditions where bandwidth may be a concern due to increased latency on WAN links.

The other choices do not accurately reflect the primary reasons or technical considerations behind using isolated subnets for VPN clients, which is why they are less relevant in this context.
