TestOut Network Pro Chapters 1-9 ExamYou have implemented a network where each device provides shared files with all other
devices on the network.
What type of network do you have? - Answer- Peer-to-peer
You have implemented a network where hosts are assigned specific roles, such as for
file sharing and printing. Other hosts access those resources but do not host services of
their own.
What type of network do you have? - Answer- Client-server
Which of the following geographic network types are typically managed by a city as a
public utility? - Answer- Metropolitan Area Network (MAN)
You have a network that uses a logical ring topology. How do messages travel through
the network? - Answer- Messages travel from one device to the next until they reached
the destination device.
You have a network that uses a logical bus topology. How do messages travel through
the network? - Answer- Messages are broadcast to all devices connected to the
network.
Which of the following topologies connects all devices to a trunk cable? - Answer- Bus
Which of the following topologies connects each device to a neighboring device? -
Answer- Ring
In which of the following topologies does each device on the network act as a repeater,
sending the signal to the next device? - Answer- Ring
Which of the following topologies connects each network device to a central hub? -
Answer- Star
You have implemented an ad-hoc wireless network that doesn't employ a wireless
access point. Every wireless network card can communicate directly with any other
wireless network card on the network.
,What type of physical network topology has been implemented in this type of network? -
Answer- Mesh
You have been asked to implement a network infrastructure that will accommodate
failed connections.
Which of the following network topologies provides redundancy for a failed link? -
Answer- Mesh
You want to implement a fault tolerant topology as you interconnect routers on your
wide area network.
Which of the following would meet your needs? - Answer- Mesh
What device is used to create a physical star topology? - Answer- Switch
You have a small network that uses a hub to connect to multiple devices.
What physical topology is used? - Answer- Star
You have been asked to implement a wired network infrastructure that will
accommodate failed connections. You don't have a large budget, so you decide to
provide redundancy for only a handful of critical devices.
Which of the following network topologies should you implement? - Answer- Partial
Mesh
Which two of the following are included as part of the Data Link Layer? - Answer- -
Identifying physical network device
-Controlling how messages are propagated through the network
In the OSI Model, what is the primary function of the Network Layer? - Answer- Routes
messages between networks
In the OSI Model, which of the following functions are performed at the Presentation
Layer? - Answer- -Specify data format
-Encrypt and compress data
In the OSI Model, which of the following functions are performed at the Application
Layer? - Answer- -Integration of network functionality into the host operating system
-Enabling communication between network clients and services
,Which of the following functions are performed at the Physical Layer of the OSI Model?
- Answer- Movement of data across network cables
The Data Link Later of the OSI Model is comprised of two sublayers.
What are they? - Answer- -LLC
-MAC
Which of the following are functions of the MAC sublayer? (Select two) - Answer- -
Defining a unique hardware address for each device on the network
-Letting devices on the network have access to the LAN
Which OSI Model layer is responsible for guaranteeing reliable message delivery? -
Answer- Transport
Match each layer of the TCP/IP model on the left with the corresponding layer of the
OSI model on the right. Each option on the left can be used more then one. - Answer-
Presentation-Application
Data Link-Network Interface
Application-Application
Session-Application
Network-Internet
Transport-Transport
Match the network function or device on the left with the OSI model layer it is associated
with on the right. - Answer- Application-HTTP
Presentation-ASCII
Session-Session ID Number
Transport-Port Numbers
Network-Router
Data Link-Switch
Physical-Wireless Access Point
At what OSI layer does a router operate to forward network messages? - Answer-
Network
Your company purchase a new bridge, which filters packets based on the MAC address
of the destination computer. On which layer of the OSI Model is this device functioning?
- Answer- Data Link
At which layer of the OSI Model do hubs operate? - Answer- Physical
Which of the following devices operate at OSI Model layer 2? (Select two) - Answer- -
Network Interface Card
-Switch
, Which three of the following devices operate at the Data Link Layer of the OSI Model? -
Answer- -Bridges
-Network Interface Cards
-Switches
Match the description on the left with the appropriate network signal line code on the
right. - Answer- Non-Return-to-Zero
Binary 1s are represented by positive voltage while 0s are represented by negative
voltage. There is no zero voltage state between bits.
Manchester
The transition from one voltage level to another is used to represent binary data
Return-to-Zero Inverted
A 0 is represented by sending a light pulse. A 1 is represented by sending no light
pulse.
Return-to-Zero
Binary 0s and 1s are transmitted by sending voltage pulses, with the voltage returning
to zero between pulses.
Match each network signaling method on the left with its corresponding definition on the
right. - Answer- Uses the entire network medium as a single transmission channel-
Baseband
Combines signals from multiple channels into a single channel.-De-multiplexing
Assigns different frequencies to different channels on the same network medium.-
Frequency-division multiplexing
Divides the transmission medium into several channels.-Broadband
Measures the number of times a signal in a communications channel changes state.-
Baud rate
Measures the number of data bits transmitted in one second in a communication
channel.-Bit rate
Network Signaling is a function of which later of the OSI Model? - Answer- Physical
Layer
Based on the diagram, which network line code technique is being used? - Answer-
Non-Return-to-Zero
Which protocol is used on the World Wide Web to transmit Web pages to Web
browsers? - Answer- HTTP
