 * <p>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.</p>
 *          <p>If you specified a VPC when you created the Client VPN endpoint or if you have previous subnet associations, the specified subnet must be in the same VPC. To specify a subnet that's in a different VPC, you must first modify the Client VPN endpoint (<a>ModifyClientVpnEndpoint</a>) and change the VPC that's associated with it.</p>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { EC2Client, AssociateClientVpnTargetNetworkCommand } from "@aws-sdk/client-ec2"; // ES Modules import
 * // const { EC2Client, AssociateClientVpnTargetNetworkCommand } = require("@aws-sdk/client-ec2"); // CommonJS import
 * const client = new EC2Client(config);
 * const input = { // AssociateClientVpnTargetNetworkRequest
 *   ClientVpnEndpointId: "STRING_VALUE", // required
 *   SubnetId: "STRING_VALUE", // required
 *   ClientToken: "STRING_VALUE",
 *   DryRun: true || false,
 * };
 * const command = new AssociateClientVpnTargetNetworkCommand(input);
 * const response = await client.send(command);
 * ```
