  Associates a target network with a Client VPN endpoint. A target network is a subnet in a VPC. You can associate
  multiple subnets from the same VPC with a Client VPN endpoint. You can associate only one subnet in each
  Availability Zone. We recommend that you associate at least two subnets to provide Availability Zone redundancy.
