what are the likely results?
Given: XYZ Corporation is experiencing connectivity problems with their existing building-tobuilding bridge link. A concrete wall on the roof of one building is partially blocking the Fresnel
Zone, and the connection is dropping many frames. The administrator moves the antenna to an
area not obstructed by the concrete wall and then realizes the RF cable cannot reach the new
location.
If an extension cable is added to move the antenna, what are the likely results?
What specifications should be evaluated for an antenna before it is implemented in a WLAN system?
What specifications should be evaluated for an antenna before it is implemented in a WLAN
system? (Choose three)
What WLAN topics should be addressed by a company security policy?
Given:
The network administrator at XYZ Company recently attended a training class on wireless security
and realized that he should update the corporate security policy to address WLAN technology. The
network administrator is listing the items that should be addressed in the security policy update,
and has asked for your input.
What WLAN topics should be addressed by a company security policy? (Choose 4)
What non-standard power save behavior is used by most Wi-Fi devices in actual implementations?
Given: As defined in the 802.11 specification, legacy Power Save requires an inefficient back-andforth frame exchange process. Due to this inefficiency, many WLAN device implementations use a
variation of 802.11 Power Save to accomplish the same function.
What non-standard power save behavior is used by most Wi-Fi devices in actual
implementations?
you need to include in the RF site survey report? (Choose 2)
Given: ABC Company has hired you to perform an initial site survey of their facility. During an
interview, the network manager informs you that the new wireless network must use 5 GHz bands
and OFDM, and VoWiFi handsets will be used extensively over the wireless network.
What items do you need to include in the RF site survey report? (Choose 2)
what other antenna characteristic will also change?
ABC Company has just purchased a 6 dBi patch antenna. After performing some tests with the 6
dBi antenna, they have concluded that more antenna gain is needed to cover their outdoor
courtyard. When choosing an antenna with higher gain, what other antenna characteristic will also
change?
when multiple clients are actively exchanging data with the AP?
In an 802.11n 2.4 GHz BSS, what prevents each station from using the full network bandwidth
(e.g. 130 Mbps) when multiple clients are actively exchanging data with the AP? (Choose two)
What is the center frequency of channel 2?
Given:
The center frequency of channel 1 in the 2.4 GHz ISM band is 2.412 GHz (2412 MHz).
What is the center frequency of channel 2?
