You need a network that provides centralized authentication for your users. Which of the following
logical topologies should you use?
VLANs
Peer-to-
peer
Client-server
Mesh
You need a topology that is scalable to use in your network. Which of the following will you install?
Bus
Ring
Star
Mesh
Which of the following physical topologies has the most connections and is the least popular for LANs?
Bus
Star
Ring
Mesh
In a physical star topology, what happens when a workstation loses its physical connection to another device?
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.
Which type of WAN technology uses labels, which enables priority of voice through the network?
VPN
T1
MPLS
LAN
Bus
What is a logical grouping of network users and resources called?
WAN
LAN
MPLS
Host
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
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
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
Which of the following is a disadvantage of the star topology?
When a single port on the central concentrating device fails, the entire network loses
connectivity.
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 compared to the host
used when implementing a physical bus.
It is more difficult to add stations and troubleshoot than with other topologies.
What is a difference between a LAN and a WAN?
WANs require a router.
WANs cover larger geographical areas.
WANs can utilize either private or public data transport.
All of the above.
