CWS-100 Practice Test-1 Practice Questions and Answers 100% Pass In the 2.4GHz range, what distance between the center frequencies (in megahertz) is required for two channels to be considered nonoverlapping for HR/DSSS? - ANSWER-BB?? Why is a 2.4 GHz RF signal able to propagate through a section of drywall and be received at a higher signal strength than a 5 GHz RF signal when they are both transmitted using the same transmit power? - ANSWER-2.4 GHz signals have a longer wavelength. Note: Not only do lower frequencies propagate farther due to their longer wavelength, but they also penetrate obstructions better, resulting in higher signal strengths on the opposite side of the obstruction from the AP than would happen if a higher frequency were used. This is one of the reasons you see 2.4 GHz sill in use in so many places like logistics and warehousing. What is the purpose of a WLAN Management system? - ANSWER-To allow centralized AP administration. Note: WLAN Management systems allow centralized administration of WLAN APs and controllers. The management system may be on premises or hosted in the Cloud so cloud based administration is not always provided. Copyright © KAYLIN 2024/2025 ACADEMIC YEAR.

A local database is used when no centralized solution is available. Increasing the transmit power used by an access point will result in an increase in what characteristic of an RF signal? - ANSWER-Amplitude Note: The term amplitude is used to describe the power of an RF signal. Any change in transmit power of an RF signal will change the amplitude of that signal. What phenomenon of wireless transmissions is deemed to have a negative impact on SISO deployments but is desirable in MIMO deployments? - ANSWER-Multipath Note: All of the reflected signals caused by multipath are something you try to mitigate using antenna diversity in a SISO network. However, in a MIMO network the reflections caused by multipath give the receiver additional instances of the same signal, allowing for better decoding of the special streams. Within what mode is an access point operating when it is collecting information wirelessly for a Wireless Intrusion Prevention System (WIPS) and not supporting clients? - ANSWER-Monitor Mode Copyright © KAYLIN 2024/2025 ACADEMIC YEAR. ALL RIGHTS RESERVED Copyright ©Stuvia International BV Page 3/29 Note: Monitor Mode or Scanner Mode is used to turn an access point into a sensor for a WIPS. When used in this mode, client support is not available on the radios used by the access point to scan. The component used to connect an antenna to a radio that uses a different connector type is most commonly referred to by what name? - ANSWER-A Pigtail Note: The component that is used to connect antennas and radios using different connector types is most commonly referred to as a pigtail. As a station moves closer to an access point it begins to use a higher data rate than it was using before at a greater distance. What is the name used to describe this behavior? - ANSWER-Dynamic Rate Switching (DRS) Note: Client devices and access points negotiate the fastest data rate they both support to improve performance. As a stations moves about, the signal from the access point may be detected as growing weaker or growing stronger. The signal strength with which a station detects an access point is used by the station to determine the data rate it should be using to remain connected to the access point. The stronger the signal strength detected the higher the data rate used. The lower the signal strength the lower the data rate used. This process is called Dynamic Rate Switching (DRS). What should you consider when deploying additional access points in a wireless LAN to increase capacity? - ANSWER-All of these important factors: a. Channels already in use by existing access points b. The number of concurrent connections required in the service set area Copyright © KAYLIN 2024/2025 ACADEMIC YEAR. ALL RIGHTS RESERVED Copyright ©Stuvia International BV Page 4/29 c. Distance of new AP's from the mounting points of existing access points Note: When expanding a wireless LAN there are many factors to take into account with regard to existing access points. APs may need to be moved, power levels adjusted, channels adjusted, or APs may need to be replaced with newer devices. Expanding an existing WLAN can be as large a challenge as deploying a new one. When deploying an access point in an office environment, what is a reason to use an external antenna vs. using an access point with an internal antenna? - ANSWER-To provide the desired coverage Note: Antennas not only amplify signals they also help to shape the coverage. However, most office use access points with internal antennas for looks and to reduce the number of stations that are able to see and connect to any one access point. Users within a company have a need to print wirelessly. The office manager has purchased a wireless printer for their use. What is the best way for printer be configured for use in the office? - ANSWER- Connect the printer to the network via Ethernet cable, disable the wireless card in the printer and treat the printer as any other network asse
