What type of VPN is likely being used if web pages and video streaming are slow for a remote team member?

1. A split VPN tunnel

2. A full VPN tunnel

3. A mobile VPN

4. A client-to-site VPN

The correct answer is: A full VPN tunnel

A full VPN tunnel is likely being used if web pages and video streaming are slow for a remote team member. In a full VPN tunnel, all traffic from the user's device is routed through the VPN server, which can lead to slower performance due to several factors such as increased latency from the additional routing, potential bandwidth limitations of the VPN server, and encryption overhead. When all internet traffic, including standard web browsing and streaming, is encrypted and sent through the VPN, it results in a bottleneck effect, particularly if the VPN server has limited resources or if there are many users connected simultaneously. In contrast, a split VPN tunnel allows certain traffic to bypass the VPN, maintaining performance for regular internet browsing and streaming by allowing them to connect directly to the internet. Mobile VPNs typically focus on providing secure connectivity while on the move, and client-to-site VPNs describe a specific architecture for secure connections from individual clients to a corporate network, which may not necessarily affect performance in the same way. Thus, slow performance in web browsing and video streaming suggests that the remote user is experiencing the effects of a full VPN tunnel.
