Question 12: 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.
Correct Answer: E
