Answer: Switches prevent the broadcast of packets to all network segments.
2. What are some basic questions you should ask a customer before visiting the customer's facility to perform a site survey?
Answer: The anticipated number of users, security requirements, data throughput requirements, and budget.
3. What information should you gather during the wireless local area network (WLAN) site survey in a convention center for an upcoming trade show?
Answer: Identify who will be installing access points (AP) in ceilings that could be 40 feet high.
4. What test should you perform during the site survey to enable the design engineer to understand and control what the user's experience will be on the wireless local area network (WLAN)?
Answer: A data throughput test.
5. Why is it suggested that all data collected as part of a site survey for a wireless local area network (WLAN) be included in the survey report as an attachment, appendix, or separate set of documentation?
Answer: The data could be needed in the future.
6. What are some of the access points (AP) facts that should be detailed in a wireless local area network (WLAN) site survey?
Answer: Location within facility, antenna type to be used, power output settings, how power will be provided to unit, and the expected data throughput per unit
7. Ideally, what should your next step be after you complete the wireless local area network (WLAN) site survey and provide the survey results in a report to the customer?
Answer: A wireless consulting firm should be given the site survey report so that it will then be able to provide effective information on equipment purchasing and security solutions.
8. What should you note in the wireless local area network (WLAN) site survey if a semidirectional antenna is required for adequate coverage?
Answer: The antenna orientation along with the antenna's side and back lobes for coverage and security reasons.
9. What are some desired features of an access point (AP) used to perform wireless local area network (WLAN) site surveys?
Answer: Variable output power and external antenna connectors.

Answer: By checking for signal strength and coverage areas while roaming around the facility.
11. What are some requirements of a wireless local area network (WLAN) in a hospital that make it an effective training ground for individuals who want to immerse themselves in WLAN technology?
Answer: Roaming across large distances, a limited number of users on an access point (AP) due to mandated security, and medical applications that are often connection-oriented between the client and server.
12. What uses the 2.4-GHz band and runs at 54 Mbps?
Answer: 802.11g
13. What is one reason why broadband cable operators install fiber-optic cable in stages instead of changing the infrastructure all at once?
Answer: Changing the infrastructure all at once would cause too many service disruptions.
14. What is the difference between the fiber-to-the-node (FTTN) and fiber-to-the-curb (FTTC) topologies?
Answer: An FTTC is allowed a smaller number of RF amplifiers between the optical fiber and the customer premises.
15. Which of these components is used in a passive optical network (PON)? [Show Less]
