Given: The 802.11ac APs you have selected for your public access deployment support many of the PHY and MAC enhancements offered by the 802.11n and

802.11ac amendments. The AP is configured for a single-band (2.4 GHz) and only allows 20 MHz channels. The WLAN radio in the AP is a 3x3 802.11n chip that supports two spatial streams.

What is the maximum MCS rate that could be supported by this AP?

A. 54 Mbps

B. 65 Mbps

C. 108 Mbps

D. 144 Mbps

You are site surveying a network for VoWiFi. You have positioned an AP for a manual survey and are moving away from the AP with a phone in Survey Mode in your hand and you are reading the RSSI value of the signal received from the AP. You have previously determined that the noise floor was approximately -94 dBm on this floor of the building. The phones documentation does not specify a recommended RSSI or SNR value for best performance.

Based on the information provided and the type of device (VoWiFi phone) you are deploying, what minimum RSSI should you plan for in all areas you are monitoring and where VoWiFi service is desired?

A. - 75 dBm

B. - 72 dBm

C. - 67 dBm

D. - 62 dBm

In 802.11, clients are required to be calibrated for RSSI and SNR reporting to:

A. Within +/5 dB

B. Within +/3 dB

C. Within +/1 dB

D. Within +/0.5 dB

E. Within +/0.25 dB

F. No specific value

If radar has reportedly been detected on your WLAN deployment, what bands would you consider avoiding? Response:

A. 5 GHz UNII-2 and 2e

B. 5 GHz UNII-2 and 3

C. 5 GHz UNII-2, 2e, and 3

D. 5 GHz UNII-1 and 2

E. 5 GHz UNII-1, 2, and 3
