You have been hired by the ABC Corporation to conduct an indoor site survey.
What information will be in the final site survey report that is delivered? (Choose two.)
- A . Security analysis
- B . Coverage analysis
- C . Spectrum analysis
- D . Routing analysis
- E . Switching analysis
Which type of 802.11 frame is used during UL-OFDMA by Wi-Fi 6 clients to communicate to the AP about their transmit needs?
- A . BSR
- B . BSRP
- C . MU-RTS
- D . MU-BAR
- E . BQRP
You support a WLAN using dual-band 802.11ac three stream access points. All access points have both the 2.4 GHz and 5 GHz radios enabled and use 40 MHz channels in 5 GHz and 20 MHz channels in 2.4 GHz. A manager is concerned about the fact that each access point is connected using a 1 Gbps Ethernet link. He is concerned that the Ethernet link will not be able to handle the load from the wireless radios.
What do you tell him?
- A . His concern is valid and the company should upgrade all Ethernet links to 10 Gbps immediately.
- B . His concern is valid and the company should immediately plan to run a second 1 Gbps Ethernet link to each AP.
- C . His concern is invalid because the AP will compress all data before transmitting it onto the Ethernet link.
- D . Due to 802.11 network operations and the dynamic rates used by devices on the network, the two radios will likely not exceed the 1 Gpbs Ethernet link.
What two ISM bands are used by microwave ovens, cordless home telephones, baby monitors, and wireless video cameras? (Choose two)
- A . 902 MHz
- B . 2.4 GHz
- C . 5.8 GHz
- D . 7.6 GHz
802.11g has a maximum transmission rate of _____ Mbps when using (ERP) technology.
- A . 12
- B . 24
- C . 120
- D . 54
You are troubleshooting a problem with a new 802.11ax AP. While the AP supports four spatial streams, most clients are only achieving maximum data rates of 150 Mbps.
What is the likely cause?
- A . The clients are 802.11n devices
- B . The clients are only two stream 802.11ax clients
- C . Contention caused by an overlapping BSS
- D . Non-Wi-Fi interference in the channel
What statement about the IEEE 802.11e QoS facility is true?
- A . 802.11 QoS is achieved by giving high priority queues a statistical advantage at winning contention.
- B . Four 802.1p user priorities are mapped to eight 802.11 transmit queues.
- C . When the Voice queue has frames awaiting transmission, no data will be transmitted from the Best Effort queue.
- D . To improve efficiency, Block Acknowledgments are required for Voice and Video WMM queues.
- E . 802.11 control frames are assigned to the 802.11 EF priority queue.
ACK and CTS-to-self frames follow which interframe space?
- A . EIFS
- B . DIFS
- C . PIFS
- D . SIFS
- E . LIFS
What three main components constitute an 802.1X/EAP framework? (Choose all that apply.)
- A . Supplicant
- B . Authorizer
- C . Authentication server
- D . Intentional radiator
- E . Authenticator
You are selecting antennas for a WLAN operating in the 5 GHz frequency band.
What specifications should be evaluated for an antenna before it is implemented in this WLAN system? (Choose 3)
- A . 802.11ad compatibility
- B . TPC support
- C . Impedance in Ohms
- D . Elevation Beamwidth
- E . Return Loss Rating
- F . Operating Frequencies
