• a global routing prefix that is used to identify the portion of the network address provided by a local administrator
• an interface ID that is used to identify the local host on the network
• an interface ID that is used to identify the local network for a particular host
• a subnet ID that is used to identify networks inside of the local enterprise site

12. Which two things can be determined by using the ping command? (Choose two.)

• the IP address of the router nearest the destination device
• whether or not the destination device is reachable through the network
• the average time it takes each router in the path between source and destination to respond
• the number of routers between the source and destination device
• the average time it takes a packet to reach the destination and for the response to return to the source
