-
Bus
-
Ring
-
Star
-
Mesh
Correct Answer
A. StarExplanation

Which of the following physical topolgies has the least likelihood of having a collision?
-
Bus
-
Start
-
Ring
-
Mesh
Correct Answer
A. MeshExplanation
D. Only a Mesh physical topology has point-to-point connections to every device, so it has the least likelihood of ever having a collision.Rate this question:

In a physical-star topology, what happens when a workstation loses its physical connection
-
The ring is broken, so no devices can communicate.
-
Only that workstation loses its ability to communicate.
-
That workstation and the device it's connected to lose communication with the rest of the network.
-
No devices can communicate because there are now two unterminated network segments.
Correct Answer
A. Only that workstation loses its ability to communicate.Explanation
B. In a star topology, each workstation connects to a hub, switch, or similar central device, but not to other workstations. The benefit is when connectivity to the central device is lost, the rest of the network lives on.Rate this question:

You want to remotely log into an office computer using remote desktop in a secure manner. Which of the following should you use?
-
VPN
-
Tagged packets
-
VLANs
-
Telnet
-
SSH
Correct Answer
A. VPNExplanation
A VPN (Virtual Private Network) provides a secure connection to another network over the internet. It encrypts data, ensuring privacy and security, which is essential for safely accessing an office computer remotely via remote desktop. VPNs protect against eavesdropping and unauthorized access.Rate this question:

What is a logical grouping of network users and resources connected to administratively defined ports on a switch?
-
Host
-
Hub
-
VLAN
-
VTP
Correct Answer

Which of the following is a concern when using peer-to-peer networks?
-
Where to place the server
-
Whose computer is least busy and can act as the server
-
The security associated with such a network
-
Having enough peers to support creating such a network
Correct Answer
A. The security associated with such a networkExplanation
C. Security is easy to relax in a peer-to-peer environment. Because of the trouble it takes to standardize authentication, a piecemeal approach involving users' personal preferences develops. There are no dedicated servers in a peer-to-peer network, and such a network can be created with as few as two computers.. Security is easy to relax in a peer-to-peer environment.

Which of the following is an example of when a point-to-multipoint network is called for?
-
When a centralized office needs to communicate with many branch offices
-
When a full mesh of WAN links is in place
-
When multiple offices are daisy-chained to one another in a line
-
When there are only two nodes in the network to be connected
Correct Answer
A. When a centralized office needs to communicate with many branch officesExplanation
A. When a central office, such as a headquarters, needs to communicate directly with its branch offices, but the branches do not require direct communication with one another, the point-to-multipoint model is applicable. The other scenarios tend to indicate the use of a point-to-point link between sites.Rate this question:

Which of the following is an example of a LAN?
-
Ten buildings interconnected by Ethernet connections over fiber-optic cabling
-
Ten routers interconnected by frame-relay circuits
-
Two routers interconnected with a T1 circuit
-
A computer connected to another computer so they can share resources
Correct Answer
A. A computer connected to another computer so they can share resourcesExplanation
A LAN (Local Area Network) is a network that connects devices within a limited geographical area, such as a home, office, or 1 building. The other options describe networks that span larger distances or use technologies that are not typically associated with LANs.Rate this question:

Which of the following is a disadvantage of the star topology?
-
When a port on the central concentrating device fails, the attached end device loses connectivity to the rest of the network.
-
When the central concentrating device experiences a complete failure, all attached devices lose connectivity to the rest of the network.
-
In a star topology, a more expensive type of host must be used when compared to the host used when implementing a physical bus.
-
It is more difficult to add stations and troubleshoot than with other topologies.
Correct Answer
A. When the central concentrating device experiences a complete failure, all attached devices lose connectivity to the rest of the network.Explanation
B. The only disadvantage mentioned is the fact that there is a single point of failure in the network. However, this topology makes troubleshooting easier; if the entire network fails, you know where to look first. The central device also ensures that the loss of a single port and the addition of a new device to an available port do not disrupt the network for other stations attached to such a device.Rate this question:

What is a difference between a LAN and a WAN?
-
WANs need a special type of router port.
-
WANs cover larger geographical areas.
-
WANs can utilize either private or public data transport.
-
All of the above.
Correct Answer
A. All of the above.Explanation
D. A typical WAN connects two or more remote LANs together using someone else's net¬work (your ISP's) using a router. Your local host and router see these networks as remote networks and not as local networks or local resources.Rate this question:

What does the acronym VPN stand for?
-
Virtual processor network
-
Virtual passive network
-
Virtual private network
-
Variable-length private network
Correct Answer
A. Virtual private networkExplanation
C. Virtual private networks (VPNs) allow for the creation of private networks across the Internet. A VPN makes your local host part of the remote network by using the WAN link that connects you to the remote LAN.Rate this question:

In what type of network are all computers considered equals and do they not share any central authority?
-
Peer-to-peer
-
Client-server
-
Physical topology
-
None of the above
Correct Answer
A. Peer-to-peerExplanation
A. In a peer-to-peer network, all computers are considered equals. It is up to the computer that has the resource being requested to perform a security check for access rights to its resources.Rate this question:
-

What advantage does the client-server architecture have over peer-to-peer?
-
Easier maintenance
-
Greater organization
-
Tighter security
-
All of the above
Correct Answer
A. All of the aboveExplanation
D. In client-server networks, requests for resources go to a main server that responds by handling security and directing the client to the resource it wants, instead of the request going directly to the machine with the desired resource (as in peer-to-peer).Rate this question:

Which type of topology has the greatest number of physical connections?
-
Point-to-multipoint
-
Star
-
Point-to-point
-
Mesh
Correct Answer
A. MeshExplanation
D. In the mesh topology, there is a path from every machine to every other one in the net¬work. A mesh topology is used mainly because of the robust fault tolerance it offers—if one connection goes on the blink, computers and other network devices can simply switch to one of the many redundant connections that are up and running.Rate this question:

Which network topology establishes a single communication path through a direct connection between two routers?
-
Point-to-point
-
Star
-
Bus
-
Straight
Correct Answer
A. Point-to-pointExplanation
A. As its name implies, in a point-to-point topology you have a direct connection between two routers, giving you one communication path. The routers in a point-to-point topology can either be linked by a serial cable, making it a physical network, or be far away and only connected by a circuit within a frame-relay network, making it a logical network.Rate this question:
