In order to properly manage the network traffic in your organization, you need a complete
understanding of protocols and networking models. In regards to the 7-layer OSI model, what is
the function of the
Transport Layer?

A.
The Transport layer allows two applications on different computers to establish, use, and end a
session. This layer establishes dialog control between the two computers in a session, regulating
which side transmits, plus when and how long it transmits.

B.
The Transport layer manages logical addresses. It also determines the route from the source to
the destination computer and manages traffic problems, such as routing, and controlling the
congestion of data packets.

C.
The Transport layer packages raw bits from the Physical (Layer 1) layer into frames (structured
packets for data). Physical addressing (as opposed to network or logical addressing) defines how
devices are addressed at the data link layer. This layer is responsible for transferring frames from
one computer to another, without errors. After sending a frame, it waits for an acknowledgment
from the receiving computer.

D.
The Transport layer transmits bits from one computer to another and regulates the transmission
of a stream of bits over a physical medium. For example, this layer defines how the cable is
attached to the network adapter and what transmission technique is used to send data over the
cable.

E.
The Transport layer handles error recognition and recovery. It also repackages long messages,
when necessary, into small packets for transmission and, at the receiving end, rebuilds packets
into the original message. The corresponding Transport layer at the receiving end also sends
receipt acknowledgments.
