| Concerning the OSI model, what functions does the transport layer perform?
A. The transport layer ensures that all packets are delivered error-free, in the correct sequence and with no packet loss or packet duplication.
B. The transport layer handles moving the packets between devices that more than one link away from each other.
C. The transport layer allows for separate computers to share a common connection, called a session.
D. The transport layer is responsible for moving the data across the transmissions medium from source computer to destination computer.
E. The transport layer is responsible for translating the data produced by applications in to usable packets for transmission on the network.
F. The transport layer is the man who puts down the railroad tracks for the trains to run on.
Answer on Monday, Have a good weekend folks.

"A" is my answer...and the right one. TCP uses sliding window for flow control (TCP works at transport layer). Also, is responsible for acknowledgment of receipts and sequencing of packets. | |

| I'm going to have to go with A on this one. | |

| A
hmm, and after some reading, E too
or not... not sure | |

So I'll go A C E | |

and the answer is A. The transport layer ensures that all packets are delivered error-free, in the correct sequence and with no packet loss or packet duplication.
From the Windows 2000 Server Administrators Companion (Appendix C), the transport layer is the layer responsible for ensuring that all packets are sent out error-free. The transport layer breaks up larger pieces of data into smaller pieces and assigns each one a sequence number, which ensure that no packet loss or packet duplication occurs during the transmission.
