Correct Answers
TCP/IP is a data link protocol that is used on the internet. T/F - Answer-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 - Answer-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 - Answer-
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 - Answer-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 -
Answer-True
TCP is the network layer protocol used on the Internet today. T/F - Answer-False - This
is IP
IP is responsible for error-free deliver of packets on a TCP/IP network T/F - Answer-
False
The TCP portion of TCP/IP performs linking to the application layer. - Answer-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. - Answer-
False
TCP includes a sequence number so that the packets can be reassembled at the
destination in the correct order. - Answer-True
The latest version of IP is IPv7, which increases the address space from 128 bits to 256
bits. - Answer-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 - Answer-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. - Answer-True
The standard port number for Telnet is 53 - Answer-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. - Answer-True
Connectionless routing sets up a TCP connection, or virtual circuit between a sender
and receiver. - Answer-False
TCP/IP operates only as connection-oriented. - Answer-False
Quality of Service routing is a special type of connection-oriented routing in which
different connections are assigned different priorities. - Answer-True
An example of an application layer address is www.indiana.edu - Answer-True
The network layer address for IP is ten bytes long when using IPv4. - Answer-False
The data link layer address is generally encoded in a network card by the card's
manufacturer - Answer-True
IPv4 addresses offer unlimited opportunity for expansion and growth on the Internet -
Answer-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 - Answer-True
The most common standard for dynamic addressing for TCP/IP networks is Dynamic
Host Control Protocol. - Answer-True
Translating an application layer address to a network layer address and finally to a data
link layer address is called address resolution. - Answer-True
Part of the function of address resolution is translating the application layer address of
the destination into a network layer address. - Answer-True
Domain Name Servers provide the equivalent of directory assistance for application
layer addresses. - Answer-True
An Address Resolution Protocol message is broadcast to all computers in a subnet to
find the data link layer address. - Answer-True
