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 though 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.
