 4A new network is to be configured on a router. Which of the following tasks must be completed to configure this interface and implement dynamic IP routing for the new network? (Choose three.)  
Select the routing protocol to be configured.

Assign an IP address and subnet mask to the interface
 Update the ip host configuration information with the device name and new interface IP address.

 4A new network is to be configured on a router. Which of the following tasks must be completed to configure this interface and implement dynamic IP routing for the new network? (Choose three.)

.  The TCP Protocol Interpreter process verifies the transmitted data at source and destination.
