Telecom Exam 2 Complete Questions
and Verified Detailed Answers
TCP/IP is a data link protocol that is used on the internet. T/F - ✔✔False - it is a
network layer protocol
The network layer sits directly between the application layer and the data link
layer in the Internet five-layer model. T/F - ✔✔False - it is between the data link
and transport layers
The network layer is responsible for end-to-end delivery of the message. T/F -
✔✔False - the transport layer does this
The transport layer routes messages through the network selecting the best
path from the source to the destination station. T/F - ✔✔False - this is the
networking layer
The transport layer process running on the destination computer, reassembles
the fragmented application message before passing it up to the application
layer. T/F - ✔✔True
TCP is the network layer protocol used on the Internet today. T/F - ✔✔False -
This is IP

,IP is responsible for error-free deliver of packets on a TCP/IP network T/F -
✔✔False
The TCP portion of TCP/IP performs linking to the application layer. - ✔✔True
The source port identifier in the TCP header tells the TCP software on the
destination computer, which application on the destination it should pass the
packet to. - ✔✔False
TCP includes a sequence number so that the packets can be reassembled at the
destination in the correct order. - ✔✔True
The latest version of IP is IPv7, which increases the address space from 128 bits
to 256 bits. - ✔✔False
To help determine to which application a transmission should be delivered on a
particular computer, TCP uses the application layer port addresses to distinguish
among many open applications on a computer - ✔✔True
Source port address is the logical address generated by the application layer on
the source computer to identify the application, which is sending the data. -
✔✔True
The standard port number for Telnet is 53 - ✔✔False

, Because there is a limit on the length of a frame that the data link layer can
transmit from node to node, the transport layer breaks up the message from
the application layer into several smaller packets. - ✔✔True
Connectionless routing sets up a TCP connection, or virtual circuit between a
sender and receiver. - ✔✔False
TCP/IP operates only as connection-oriented. - ✔✔False
Quality of Service routing is a special type of connection-oriented routing in
which different connections are assigned different priorities. - ✔✔True
An example of an application layer address is www.indiana.edu - ✔✔True
The network layer address for IP is ten bytes long when using IPv4. - ✔✔False
The data link layer address is generally encoded in a network card by the card's
manufacturer - ✔✔True
IPv4 addresses offer unlimited opportunity for expansion and growth on the
Internet - ✔✔False
Subnet masks tell computers what part of an IP address is to be used to
determine whether a destination is in the same subnet or in a different subnet -
✔✔True
