DCOM 101 Final Exam ACTUAL UPDATED QUESTIONS AND CORRECT ANSWERS
The Physical layer has been divided into two sublayers, False
called the LLC sublayer and the MAC sublayer
Which layer has been subdivided into the Logical Link Data Link
Control sublayer and the Media Access Control
sublayer?
Which layer is responsible for establishing Session
communication setup between the source and
destination computers?
Switches operate at this layer Data Link Layer
Hubs operate at this layer Physical Layer
Sublayer manages access to the physical medium. Media Access Control sublayer
Computers operate at this layer. Application Layer
This sublayer is responsible for some error recovery. Logical Link Control sublayer
This is the general framework for how networking systems OSI reference model
should operate.
Routers operate at this layer Network layer
This layer handles data formatting and translation Presentation layer
This uses port numbers as source and destination Transport layer
identifiers
This handles communication setup and teardown Session layer
Which of the following is the correct order of the layers Physical, Data Link, Network, Transport, Session, Presentation, Application
of the OSI model from layer 1 to layer 7?
The process of stripping the header and trailer from a deencapsulation
PDU is called ______ _.
, You are working at the help desk and you get a message Network layer device
that a user cannot access the Internet. You open a
command prompt, ping the workstation's IP address, and
get a response. You ask the user to try the Internet again.
He does so with the same result— no connection. Which
type of device is most likely to be the problem?
At what layer do NICs operate? Data Link
Which layer of the OSI model is responsible for Presentation
encryption and decryption?
at each layer of the OSI model, data is appended to the encapsulation
original message and then sent on to the next lower
layer. What is this process called?
The Transport layer segments data into smaller chunks, MTU
the size of which is determined by which of the
following?
What does the Transport layer use to make sure that a sequence number
message is reassembled correctly on the receiving
device?
What layer is responsible for making sure that the data 6
that it sends and receives is in a format that the receiving
and sending computers can understand
