It selects the path and forwards it toward the destination host.

107. Refer to the exhibit. Router R1 has two interfaces that were configured with correct IP addresses and subnet masks. Why does the show ip route command output not display any information about the directly connected networks??

"Gateway of last resort is not set"

The directly connected networks have to be created manually to be displayed in the routing table.

The no shutdown command was not issued on these interfaces.

The gateway of last resort was not configured.

109. Which three statements characterize the transport layer protocols? (Choose three.)

TCP and UDP port numbers are used by application layer protocols.
