Which one of the following is a TRUE statement about the bottom three layers of the Open Systems
Interconnection (OSI) Reference Model?
A.
They generally pertain to the characteristics of the communicating end systems.
“The Session layer (layer 5) is responsible for establish, maintaining, and terminating
communication sessions between two computers.” Pg 79 Tittel: CISSP Study Guide. Not
Datagram
B.
They cover synchronization and error control of network data transmissions.
“The Transport layer (layer 4) ….This layer includes mechanisms for segmentation, sequencing,
error checking, controlling the flow of data, error correction and network service optimization.” Pg
79 Tittel: CISSP Study Guide. Not
Network
C.
They support and manage file transfer and distribute process resources.
“The Application itself it is not located within this layer [Application]; rather the protocols and
services required to transmit files, exchange messages, connect to remote terminals, and so on are
here.” Pg. 80 Tittel: CISSP Study Guide.

Explanation:
By exclusion: NotThe Network layer (layer 3) is responsible for adding routing information to the data. The Network
layer accepts the segment from the Transport layer and adds information to it to create a packet.
The packet includes the source and destination IP addresses. T The routing protocols are located at
this layer and include the following: Internet Control Message Protocol (ICMP) Routing Information
Protocol (RIP) Open Shortest Path First (OSPF) Border Gateway Protocol (BGP) Internet Group
Management Protocol (IGMP) Internet Protocol (IP) Internet Packet Exchange (IPX) Pg. 78 Tittel:
