CS 6250 Exam 1 UPDATED ACTUAL QUESTIONS AND CORRECT ANSWERS
(L1) How did Licklider and his team in the early 1960s Connecting two computers over a dial up telephone line
experiment w/ a precursor to the Internet?
(L1) What is the Domain Name System design to do Translate domain names into IP addresses
primarily?
(L1) What is the architectural design of the Internet Layers
protocol stack based on?
(L1) Both the data link and transport layer protocols may True
provide error correction.
(L1) What allows for communication between application Sockets
layer and transport layer?
(L1) Which of the follow protocols belong to the DNS
application layer?
UDP
DNS
IP
Ethernet
(L1) Which two protocols belong in the transport layer? UDP & TCP
, (L1) When an application sends a packet of information Encapsulation
across the network, this packet ravels down the IP stack
and undergoes what process?
(L1) According to the end-to-end principle, where should At the edges of the network
most of the Internet's functionality/intelligence be
implemented?
(L1) What is the difference between hubs, bridges, and They operate at different layers of the IP stack.
routers?
(L2) The transport layer protocols offer a logical False
connection between processes only if the hosts reside in
the same network
(L2) A sending host receives a message from the True
application and encapsulates it with the transport layer
headers before passing it down to the network layer.
(L2) An application running on a host can bind to multiple True
sockets simultaneously.
(L2) The identifier of a UDP socket is a tuple of destination True
IP address and port.
(L2) The identifier of a TCP socket is a tuple of source IP False
address and port.
(L2) UDP is considered more lightweight than TCP. True
(L2) One of the functionalities that UDP offers is to False
increase or decrease the pace with which the sender
sends data to the receiver.
(L2) UDP offers basic error checking True
(L2) Assume Hosts A,B, and C. Host A has a UDP socket False
with port 123. Hosts B and C each send their own UDP
segment to host A. Hosts B and C cannot use the same
destination port 123 for sending their UDP segment
(L2) TCP offers in-order delivery of the packets, flow True
control, and congestion control.
(L2) TCP detects packet loss using timeouts and triple True
duplicate acknowledgments.
(L2) Flow control is a rate control mechanism to protect True
the receiver's buffer from overflowing
