You are deploying a WLAN monitoring solution that utilizes distributed sensor devices. Where should sensors be deployed for best results? Choose the single best answer.

• A.In switching closets
• B.Above the plenum on each floor
• C.In critical areas where WLAN performance must be high
• D.Every 5 meters and alongside each AP

An AP is advertised as a tri-band, 4x4:4, Wi-Fi 6, 802. 11ax AP. Based on this information and assuming it is correctly advertised, what can be determined as certainly true about this AP?

• A.It supports four channels in 2.4 GHz and 4 channels in 5 GHz
• B.It supports UL-MU-MIMO
• C.It uses a modified OpenWRT firmware
• D.It has 4 radio chains

What can cause excessive VSWR in RF cables used to connect a radio to an antenna?

• A.Impedance mismatch
• B.High gain yagi antenna
• C.High gain parabolic dish antenna
• D.Radio output power above 100 mW but below 400 mw

The BSA of an AP covers the area used by the sales and marketing department. Thirty-five stations operate in this space. The users 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.Install a second AP in the coverage area
• B.Use a 40 MHz channel on the 2.4 GHz radio
• C.Use a 160 MHz channel on the 5 GHz radio
• D.Use a 40 MHz channel on the 5 GHz radio

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

• A.The frame was not delivered and must be retransmitted
• B.The frame was correctly delivered
• C.The receiver processed the frame, but did not respond with an ACK frame because 802.11w is enabled
• D.The receiver is offline
