The International Standards Organization/Open Systems Interconnection (ISO/OSI) Layers does NOT
have which of the following characteristics?
A.
Standard model for network communications
“The Open System Interconnect (OSI) is a worldwide federation that works to provide
international standards. “ Not
Physical
B.
Used to gain information from network devices such as count of packets received and routing
tables
Session
C.
Allows dissimilar networks to communicate
“A protocol is a standard set of rules that determine how systems will communicate across
networks. Two different systems can communicate and understand each other because they use the
same protocols in spite of their differences.” Pg. 343-344 Shon Harris: CISSP All-In-One Certification

QUESTION 844
Which of the following layers supervises the control rate of packet transfers in an Open Systems
Interconnections (OSI) implementation?
Transport
D.
Defines 7 protocol layers (a.k.a. protocol stacks)
Network

Transport
D.
Defines 7 protocol layers (a.k.a. protocol stacks)
Network
Explanation:
NotThe transport layer defines how to address the physical locations and /or devices on the network,
how to make connections between nodes, and how to handle the networking of messages. It is
responsible for maintaining the end-to-end integrity and control of the session. Services located in
the transport layer both segment and reassemble the data from upper-layer applications and unite it
onto the same data stream, which provides end-to-end data transport services and establishes a
logical connection between the sending host and destination host on a network. The transport layer
is also responsible for providing mechanisms for multiplexing upperlayer applications, session
establishment, and the teardown of virtual circuits. -Ronald Krutz The CISSP PREP Guide (gold
edition) pg 275-276 “Transport Layer The agreement on these issues before transferring data helps
provide more reliable data transfer, error detection and correction, and flow control and it optimizes
network services needed to perform these tasks.” Pg. 318 – 319 Shon Harris: All-In-One CISSP
