You have a server that runs Windows Server 2003 Service Pack 2 (SP2). The server is configured as a network address translation (NAT) router. The server has two network adapters and provides Internet access for the network.You need to prevent traffic on port 21 from being sent to the Internet. All other outbound traffic must be allowed.What should you do?（） A、On the network adapter that is connected to the LAN, enable TCP/IP filtering. B、On the network adapter that is connected to the Internet, enable TCP/IP filtering. C、From the Routing and Remote Access snap-in, open the properties of the interface connected to the Internet, select the Services and Ports tab, and define a new service. D、From the Routing and Remote Access snap-in, open the properties of the interface connected to the Internet, select the NAT/Basic Firewall tab, and define a new static packet filter.
A Windows Communication Foundation (WCF) solution uses two services to manage a shopping cart. Service A processes messages containing line items that total between $0 and $500. Service B processes messages containing line items that total more than $500. All messages are of equal importance to the business logic. You need to route incoming messages to the appropriate services by using WCF routing. Which two message filters should you add to the router? (Each correct answer presents part of the solution. Choose two.)（）A、a message filter with a priority of 100 that will forward messages that total between $0 and $500 to Service AB、a message filter with a priority of 0 that will forward messages that total between $0 and $500 to Service AC、a message filter with a priority of 0 that will forward all messages to Service BD、a message filter with a priority of 100 that will forward all messages to Service B
