You can find the answers to the review questions in Appendix B.

1. You need a network that provides centralized authentication for your users. Which of the following logical topologies should you use?

A. VLANs

B. Peer-to-peer

C. Client-server

D. Mesh

2. You need a topology that is scalable to use in your network. Which of the following will you install?

A. Bus

B. Ring

C. Star

D. Mesh

3. Which of the following physical topologies has the most connections and is the least popular for LANs?

A. Bus

B. Start

C. Ring

D. Mesh

4. In a physical star topology, what happens when a workstation loses its physical connection to another device?

A. The ring is broken, so no devices can communicate.

B. Only that workstation loses its ability to communicate.

C. That workstation and the device it's connected to lose communication with the rest of the network.

D. No devices can communicate because there are now two unterminated network segments.

5. Which type of WAN technology uses labels, which enables priority of voice though the network?

A. VPN

D. LAN

E. Bus

6. What is a logical grouping of network users and resources called?

A. WAN

B. LAN

C. MPLS

D. Host

7. Which of the following is a concern when using peer-to-peer networks?

A. Where to place the server

B. Whose computer is least busy and can act as the server

C. The security associated with such a network

D. Having enough peers to support creating such a network

8. Which of the following is an example of when a point-to-multipoint network is called for?

A. When a centralized office needs to communicate with many branch offices

B. When a full mesh of WAN links is in place

C. When multiple offices are daisy-chained to one another in a line

D. When there are only two nodes in the network to be connected

9. Which of the following is an example of a LAN?

A. Ten buildings interconnected by Ethernet connections over fiber-optic cabling

B. Ten routers interconnected by Frame Relay circuits

C. Two routers interconnected with a T1 circuit

10. Which of the following is a disadvantage of the star topology?

A. When a single port on the central concentrating device fails, the entire network loses connectivity.

B. When the central concentrating device experiences a complete failure, all attached devices lose connectivity to the rest of the network.

C. In a star topology, a more expensive type of host must be used compared to the host used when implementing a physical bus.

D. It is more difficult to add stations and troubleshoot than with other topologies.
