第1题：

Interface ge-0/0/2.0 of your device is attached to the Internet and is configured with an IP address and network mask of 71.33.252.17/24. A Web server with IP address 10.20.20.1 is running an HTTP service on TCP port 8080. The Web server is attached to the ge-0/0/0.0 interface of your device. You must use NAT to make the Web server reachable from the Internet using port translation. Which type of NAT must you configure?（）

• A、source NAT with address shifting
• B、pool-based source NAT
• C、static destination NAT
• D、pool-based destination NAT
