TRUE / FALSE

1. A key problem when designing data communications networks is how to adapt to new technologies while organizations change

2. Today, many organizations design networks using the building-block approach.

3. Needs analysis is the final step in the building block approach to network design.

4. The goals in the needs analysis step of network design are exactly the same when designing LANs vs. when designing WANs.

5. The step of understanding current traffic on a network provides a baseline against which future network requirements can be compared.

6. The turnpike effect results when a network is used at a much lower rate than was anticipated when it was designed.

7. Simulation is a tool that can be used in designing networks.

8. Policy-based management allows the network manager to utilize special software to set priority policies for network traffic that take effect when the network becomes busy.

9. A SLA specifies the exact type of performance that the common carrier will provide and the penalties if this performance is not provided.

10. The future of network management lies in the management of LANs, BNs, and Internet resources instead of concentrating on mainframe resources.

11. Due to changing communication technologies, most companies have combined voice and data communications functions.

12. One of the least common configuration activities is adding and deleting user accounts.

13. User profiles should enable the network manager to identify the access rights (to particular files and directories) for each user.

14. Trouble tickets are reports produced by a software package that records fault information.

15. Problem statistics are not helpful in determining whether vendors are meeting contractual maintenance commitments.

16. To ensure that critical problems get priority over less important ones, problem prioritizing is needed in a network.

17. Mean Time Between Failures is a statistic that is used to track device reliability.

18. Service level agreements specify the exact type of performance and fault conditions that an organization will accept from a common carrier or Internet service provider.

MULTIPLE CHOICE

19. The traditional network design approach does not work well for _________ networks.

a. slowly evolvingb. rapidly growingc. staticd. modestly growinge. not growing

20. Which of the following is false about staff costs for a network? a. The most expensive part of the network today is the staff who design,

operate, and maintain itb. The emphasis is on network designs that reduce staff time needed to

operate themc. Network staff are often required to learn to operate a variety of devicesd. Network staff are often required to maintain a variety of devicese. When a variety of devices are used in a network, it takes less time to

perform network management activities

a. technology designb. needs analysisc. narrow and deep analysisd. cost assessmente. distribution layering

23. In __________, the network designer examines the available technologies and assesses which options will meet the users’ needs.

a. technology designb. needs analysisc. narrow and deep analysisd. cost assessmente. distribution layering

24. In needs analysis: a. a great deal of the work has probably never been doneb. the goal is to understand what users and applications the network will

supportc. the geographic scope is not an important considerationd. a baseline of current operations is not important e. the rate of growth of network traffic is not an issue

a. Implementationb. Post-implementation reviewc. Documentationd. Simulation e. Training users

28. One reason that there are technical network integration management issues is the fact that:

a. The more different types of network technology used, the more complex network management becomes.

b. Internet protocols are very similar to traditional mainframe protocols.c. Each LAN was developed by a centralized group.d. All LANs used in an organization all use the same architecture. e. All LANs used in an organization use the same type of technology.
