| A user issues a ping 2001:db8:3040:114::88 command and receives a response that includes a code of 4. What does this code represent? | protocol unreachable |

| What are two roles of the transport layer in data communication on a network? (Choose two.) | tracking the individual communication between applications on the source and destination hosts; identifying the proper application for each communication stream |
| A user executes a traceroute over IPv6. At what point would a router in the path to the destination device drop the packet? | when the value of the Hop Limit field reaches zero |

| Why does HTTP use TCP as the transport layer protocol? | because HTTP requires reliable delivery |

| Which protocol is used by the traceroute command to send and receive echo-requests and echo-replies? | ICMP |
| A PC is downloading a large file from a server. The TCP window is 1000 bytes. The server is sending the file using 100-byte segments. How many segments will the server send before it requires an acknowledgment from the PC? | 10 segments |
| What does a client do when it has UDP datagrams to send? | It just sends the datagrams. |
| Which two characteristics are associated with UDP sessions? (Choose two.) | Received data is unacknowledged; Destination devices receive traffic with minimal delay. |
| What source IP address does a router use by default when the traceroute command is issued? | the IP address of the outbound interface |
| A user issues a ping 2001:db8:1ACE:39::10 command and receives a response that includes a code of 3. What does this code represent? | protocol unreachable |
| In what two situations would UDP be better than TCP as the preferred transport protocol? (Choose two.) | when applications do not need to guarantee delivery of the data; when a faster delivery mechanism is needed |
