To configure a point-to-site connection from an on-premises computer to VNet1, a route-based virtual network gateway is required because point-to-site connections are not supported by policy-based gateways. Thus, you need to delete the existing policy-based virtual network gateway (GW1) and create a new route-based virtual network gateway. Therefore, the correct actions are: C. Create a route-based virtual network gateway and E. Delete GW1.
