What type of site survey helps determine if roaming is functioning as intended?
- A . Passive
- B . Predictive
- C . Active
- D . Spectrum analysis walkthrough
A North American business traveler connects to a hotel’s 2.4 GHz SSID in Europe and notices low RSSI from an AP in the room, but experiences no issues with RSSI in the lobby.
What is the most likely reason for the low RSSI in the room?
- A . The AP in the room is using ZigBee instead of Wi-Fi
- B . The AP in the room is transmitting on channel 13 and the traveler associated to an AP on channels 1 through 11 in the lobby
- C . The switchport that the AP is connected to is only capable of transmitting at 10 Mbps
- D . The AP in the room is using Bluetooth instead of Wi-Fi
Why does a frame transmitted at 1 Mbps have a greater usable range than the same frame transmitted at 54 Mbps?
- A . Free space path loss causes greater signal dispersion for higher rate transmissions.
- B . Receiver sensitivity requirements are lower for frames transmitted with less complex modulation and coding.
- C . To improve reliability, 802.11 STAs increase transmit power as the signaling rate decreases.
- D . Lower data rate RF transmissions travel at higher speeds and are less likely to experience collisions.
What service must be implemented on your customers’ network to authenticate users against an LDAP database prior to access to the WLAN infrastructure being granted?
- A . NTP
- B . RADIUS
- C . SFTP
- D . TLS
You are on site, planning a network at a freight shipping company on a busy harbor. Since the preliminary WLAN design specifies support for the 5 GHz spectrum, you would like to test for radar pulses to determine if DFS channels should be supported at this facility. As a part of your spectral survey with a laptop-based analyzer, you include DFS testing to identify the presence of radar. This is done by manually observing Real-time FFT, Duty Cycle, and Active Devices charts of the spectrum analyzer software.
What potential drawback is present with this DFS test method?
- A . Many WLAN products that support DFS channels report several false positives. Ideally, the actual
WLAN equipment used in the deployment
should be used to test for DFS. - B . Some sources of 5 GHz radar, such as military ships, are mobile in nature. A longer, automated test
setup should be used to identify the
presence or absence of radar. - C . Manual identification of radar pulses using spectrum analysis charts can be very difficult due to radar’s low amplitude at the Wi-Fi receiver.
- D . Modern spectrum analyzer adapters do not provide the necessary bandwidth resolution required to detect and measure radar signatures.
When deploying long-distance 802.11 bridge links (10 miles / 16 km), what parameter may be critical for improving data flow by reducing retries caused by the long distances?
- A . The sequence control field value
- B . The acknowledgement timeout threshold
- C . The minimum transmit data rate value
- D . The CTS-to-self threshold
What is the purpose of Friis transmission equation [ (LdB) = 20 log(d) + 20 log (f) – 27.55 ]?
- A . Calculate earth bulge to determine minimum antenna height
- B . Calculate receive sensitivity for an 802.11 radio/antenna pair
- C . Calculate RF path loss in free space
- D . Calculate the loss experienced between the intentional radiator and antenna
What is the most suitable antenna option to be used when designing a WLAN infrastructure with Aps mounted on a ceiling with a height of more than 20 feet and having all of the client stations used from the floor?
- A . Patch
- B . Dish
- C . Low-gain dipole
- D . Grid
Even when a full pre-design site survey is not performed, what is always recommended to be performed within the deployment areas?
- A . A spectrum analysis walkthrough
- B . An AP-on-a-stick survey of 37% of the facility as this amount provides all of the statistical information required for good design
- C . A scan m the 5 GHz band looking for common loT interferes
- D . A scan in the Sub-i GHz bands to determine If sideband interference will impact 2 4 GHz operations
A
30 1. Given A project parameter defines a requirement or constraint (or a project that can be defined before any file imports or design actions.
What is an example of a project parameter commonly available in WLAN design software?
