Q
Peer to Peer networks have a dedicated, centralized server for clients to connect to.
A.
True
B.
False
A

B. False
Explanation: In Peer
to Peer networks all hosts can act as both a client and a server, so there is
no dedicated or centralized single server for the clients to connect to. Instead, the hosts are all
peers to one another and connect to each other to access services and resources.

Q
Modern networks must be based on either Client/Server or Peer to Peer, but can never be both.
A.
True
B.
False
A

B. False
Explanation: In modern networks both the Client/Server and Peer
to Peer models are used.
Some network services and applications require a dedicated and centralized server, while other
services and resources can be accessed directly from other hosts (peers) on the network.

Q

Remote sharing applications use protocols such as BitTorrent to create a Peer to Peer network
amongst other computers running the same software.
A.
True
B.
False

A

A. True
Explanation: BitTorrent is an example of a Peer
to Peer (P2P) file sharing protocol which allows
any computer with the BitTorrent capable software installed to join the Peer to Peer network
and share files with the other peers (even over the internet). These types of applications are
regarded as highly unsafe for use in corporate networks due to their capacity for transmitting
malware and distributing company data into the public domain without the user’s knowledge.

Q
LANs cover smaller geographic regions than WANs.
A.
TRUE
B.
FALSE
A

A. True
Explanation: Local Area Networks (LANs) are small networks that are local to a house, office, or
small group of buildings. Wide Area Networks (WANs) are the long haul networks that connect
LANs to other LANs. WANs can span across entire cities and countries and therefore cover a
much larger geographic region than LANs do.

Q
This type of device uses IP addresses to determine where to send network traffic.
A.
Router
B.
Hub
C.
WAP
D.
Server
A

A. Router
Explanation: Routers make decisions to send traffic from one network to another network
based on the destination IP address in the IP packet. The IP address of a host determines which
network it belongs to and using this information the Router can determine which local interface
or neighboring router to route the traffic to.

Router
B.
Hub
C.
WAP
D.
Server
A

A. Router
Explanation: The device that a host must send traffic to for leaving the local LAN and talking to
another network is referred to as a gateway or a default gateway. Since routers are the devices
that are capable of sending traffic from one network to another network they are also the
default gateway for a LAN.

Wireless Access Point
B.
Hub
C.
Wired Access Point
D.
Switch
A

A. Wireless Access Point
Explanation: Wireless Access Points, also knowns as WAPs, APs, Access Points, or Wireless APs
are the devices that wireless hosts connect to for access to the network.

17
Q
This type of device can be local to the network or in a remote location and provides services to
clients such as sharing of resources and files.
A.
Router
B.
Client
C.
Server
D.
Switch
A

C. Server
Explanation: Servers are the computers on networks that provide services to Clients. Servers
can reside on the local network (such as local file servers) or on a remote network (such as web
servers that host websites).

18
Q
Hubs should be used instead of switches because hubs provide for better network performance
than switches.
A.
True
B.
False
A

B. False
Explanation: Switches provide much better performance than that of hubs and should always
be used instead of a hubs. Hubs can still be used, but are rarely seen in larger enterprise
networks due to their poor performance in comparison with switches.

19
Q

B. False
Explanation: Switches provide much better performance than that of hubs and should always
be used instead of a hubs. Hubs can still be used, but are rarely seen in larger enterprise
networks due to their poor performance in comparison with switches.

A

A. True
Explanation: The simplest example of a physical Star topology is a centralized hub or switch with
other network nodes all connected to it. In this way, we can visualize that the centralized hub or
switch is the single focal point of the Star topology and if it were to fail none of the devices
connected to it would have access to the network.

20
Q
A physical topology defines how data flows through a network rather than how devices are
physically connected to one another.
A.
True
B.
False
A

B. False
Explanation: Logical topologies represent how data flows, while physical topologies represent
the physical connections between devices.

21
Q
This type of physical topology was used in the early days of Ethernet and if there was a break
anywhere in the cable it would cause the entire Ethernet segment to go down.
A.
Ring
B.
Mesh
C.
Bus
D.
Star
A

C. Bus
Explanation: Early Ethernet (ThickNet and ThinNet) connected workstations to the network via
coaxial cables that vampire tapped into a centralized and larger coaxial cable. In effect this
creates a “one cable” LAN where all workstations are connected in succession. This is a “bus”
arrangement and all transmissions are received by every workstation on the network even if the
transmission was destined for a single machine. An additional drawback is if a break happens in
any part of the cable it causes the entire bus to break and all the hosts lose their connection to
the network.

22
Q

A network topology type such as a star, bus or ring can be used to represent either a logical or
physical topology, but can not be used to represent both.
A.
True
B.
False

A

B. False
Explanation: The types of network topologies can be used to represent the way devices are
physically interconnected and/or how data logically flows through the network. For example,
the Bus topology can be used to represent the way that devices are both physically and logically
connected in the days of early Ethernet. In the same sense the Bus topology can represent how
data logically flows through a modern Ethernet hub which is a physical star topology, but a
logical bus topology. With an Ethernet switch the topology is both a physical and logical star, so
here we can see that the different types of topologies can be used to represent both physical
and logical scenarios.

23
Q
An Ethernet Hub is physical a star, but logically a bus.
A.
True
B.
False
A

A. True
Explanation: A hub provides a central point that other devices physically connect to creating the
focal point of a physical Star topology. However, inside of the hub the connections are wired in
such a way that all the ports on the hub are connected to the same internal wire or cable.
Because of this design the inner workings and logical flow of data through a hub represent a
bus topology while the way that devices physically connect to the hub represent a Star
topology.

24
Q
A single Ethernet Switch creates a topology that is both logically and physically this type…
A.
Ring
B.
Mesh
C.
Bus
D.
Star
A

D. Star
Explanation: The way devices physically connect to an Ethernet switch represents a Star
topology, which is the same as a hub. However, the way data flows through a switch is much
different than a hub which is logically a bus. In a switch each port has it’s own dedicated
connection into the switching circuitry, so the way the data flows through a switch is the same
as the way it is connected physically. In this way an Ethernet switch is both a logical Star and a
physical Star.
