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.

When acting as a RADIUS server, enterprise quality APs can use what kind of authentication database

when no centralized identity database exists? - ANSWER✔✔-Local




Note: Active Directory and eDirectory are centralized solutions. 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

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
