To monitor the process of a domain name to IP address resolution To inform routers about network topology changes UDP uses windowing and acknowledgments for reliable transfer of data.
TCP uses windowing and sequencing to provide reliable transfer of data. TCP and UDP port numbers are used by application layer protocols. TCP uses port numbers to provide reliable transportation of IP packets. When the router prompts for an address or remote host name, what IP address should the administrator enter at the prompt?Ģ Which three statements characterize the transport layer protocols? (Choose three.) The network administrator enters these commands into the R1 router: The command will have no effect on the switch.Īn error stating that VLAN 20 does not exist will be displayed and VLAN 20 is not created.
