NVCC ITN 100 Exam 2 UPDATED ACTUAL
QUESTIONS AND CORRECT ANSWERS
Which application layer process the packet is from - correct answer the source
destination port identifier tells the destination station _____________.
Connectionless - correct answer ______________ routing is most commonly used
when the application data or message can fit into one single packet.
True - correct answer 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 or false
False - correct answer tcp/ip operates only as connection-oriented
True or false
False - correct answer the standard port number for telnet is 53.
True or false
True - correct answer an address resolution protocol message is broadcast to all
computers in a subnet to find the data link layer address.
True or false
Multicast message - correct answer a special type of message that is used when sending
the same message to a specific group of computers is called a:
,Routing - correct answer ___________ is the process of determining the path that a
message will travel from sending computer to receiving computer.
False - correct answer there are four fundamental approaches to routing: centralized,
static routing, dynamic routing, and monitor routing.
True or false
True - correct answer 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 or false
Ports - correct answer used to identify application
Connection oriented - correct answer using a session to send data is called
Connectionless - correct answer sending messages without establishing a session is
Ip address - correct answer 129.79.78.193
Subnet mask - correct answer 255.255.255.0
Dynamic host configuration protocol - correct answer what does dhcp stand for?
Domain name service - correct answer what does dns stand for?
Address resolution protocol - correct answer what does arp stand for?
, Routing tables - correct answer -used to make routing decisions
-shows which path to send packets on to reach a given destination
-kept by computers making routing decisions
What is this?
Centralized routing - correct answer -routing decisions made by one computer
-not common anymore
What is this?
Decentralized routing - correct answer -decisions made by each node independently of
one another
-information needs to be exchanged to prepare routing tables
-used by the internet
What is this?
Static - correct answer -fixed routing tables
-manually configured by network managers
-local adjustments when computers added or removed
