C. 1 and 5

D. 4 and 6

What factor does not influence the distance at which an RF signal can be effectively received?

A. Free Space Path Loss

The BSA of an AP covers the area used by the sales and marketing department. Thirty-five stations operate in this space. The user indicate that they need more throughput and all stations are 5 GHz capable 802.11ac clients. The current AP configuration uses 20 MHz channels in both 2.4 GHz and 5 GHz. What is the least expensive solution available for increasing throughput for these users without implementing configuration options that are not recommended?

A. Use a 160 MHz channel on the 5 GHz radio

B. Use a 40 MHz channel on the 5 GHz radio

C. Install a second AP in the coverage area

D. Use a 40 MHz channel on the 2.4 GHz radio.

You are evaluating access points for use in the 5GHz frequency band. What PHY supports this band and supports 80 MHz channels?

A. OFDM

B. HT

C. VHT

D. ERP

A WLAN is implemented using wireless controllers. The APs must locate the controllers when powered on and connected to the network. Which one of the following methods is commonly used to locate the controllers by the APs?

A. DHCP

B. GRE

C. NTP

D. SNMP

You are troubleshooting a problem with interference from a non-802.11 device. Given that the device is not a WLAN device, you cannot use a protocol analyzer and have chosen to use a spectrum analyzer. You want to view the signal from the interfering device over time to see the activity that is generating.

What common spectrum analyzer view should you use for this analysis?

A. Waterfall/Spectrogram

B. Real-time FFT

C. APs

D. Clients

A standard PoE injector is use 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

What statement about the IEEE 802.11-2016 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. 802.11 control frames are assigned to the 802.11 EF priority queue.

D. When the Voice queue has frames awaiting transmission, no data will be transmitted from the Best Effort queue.

When an ACK frame is not received by the transmitting STA, what is assumed?

A. The frame was correctly delivered

B. The frame was not delivered and must be retransmitted

C. The receiver is offline

D. The receiver processed the frame, but did not respond with an ACK frame because 802.11w is enabled

You are attempting to explain RF shadow and how it can cause lack of coverage. What common building item frequently causes RF shadow and must be accounted for in coverage plans?

A. Wooden doors

B. Carpeted floors

C. Elevators
