You are evaluating access points for use in the 5 GHZ frequency band. What PHY supports this band and supports 80 MHz channels?
A. OFDM
B. HT
C. VHT
D. ERP
You are using a site survey tool for post-implementation validation. You have installed the appropriate adapter driver and imported a floor plan. Now, you want to take the next step in proper tool use. What must you do before gathering survey data after the floor plan is imported?
A. Install iPerf
B. Install WinPCAP
C. Calibrate the floor plan
D. Nothing, you can simply start capturing signal readings
What security solution is deprecated in the 802.11 standard and should never be used in any modern WLAN deployment?
A. AES
B. Shared Key Authentication
C. CCMP
D. Open System Authentication
When performing a validation survey for a Multiple Channel Architecture (MCA) system in a multi-tenant building with five floors, what aspect should you, as the surveyor, keep in mind?
A. The RF interference caused by passing airplanes supporting on-board Wi-Fi should be a prime consideration
B. The channel reuse pattern should be three dimensional with the RF cell extending coverage of each access point to other floors
C. The omni-directional antennas of the access points should be oriented parallel to the floor to maximize the coverage pattern across as many floors as possible
D. The Fresnel Zone is completely blocked between floors so each floor is considered a separate site survey
An 802.11-based network uses an AP and has several connecting clients. The clients include iPhones, iPads, laptops and one desktop. What WLAN use case is represented?
A. WPAN
B. Ad-hoc
C. BSS
D. IBSS
A standard PoE injector is used to power an access point requiring 802.3at. CAT6 cabling is in use. What is the maximum distance supported between the access point and the Ethernet switch with the use of a midspan power injector?
A. 100 meters
B. 300 meters
C. 328 meters
D. 200 meters
Which one of the following is not a factor considered when calculating the Link Budget for an outdoor point-to-point WLAN bridge link?
A. MU-MIMO capabilities of the bridges
B. Receive antenna gain
C. Transmit power
D. Operating frequency
A WLAN transmitter that emits a 50 mW signal is connected to a cable with 3 dB loss. If the cable is connected to an antenna with 9dBi gain, what is the EIRP at the antenna element?
A. 23 dBm
B. 26 dBm
C. 13 dBm
D. 10 dBm
You are evaluating a connection that states the data rate is 150 Mbps. What is the expected throughput of this connection?
A. Less than 150 Mbps because of 802.11 overhead and contention
B. 54 Mbps because that is the actual maximum throughput of an 802.11 connection
C. More than 150 Mbps because of compression
D. 150 Mbps because the data rate is equal to the throughput
You manage a WLAN with 100 802.11ac access points. All access points are configured to use 80 MHz channels. In a particular BSS, only 40 MHz communications are seen. What is the likely cause of this behavior?
A. The short guard interval is also enabled.
B. The clients are all 802.11n STAs or lower
C. The AP is improperly configured to use only 40 MHz of the 80 MHz allocated bandwidth
D. All clients implement single spatial stream radios
