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?
The thermal noise is at −174 dBm/Hz. A spectrum analyzer has a resolution bandwidth of 1 kHz and a 5 dB noise figure. What is the level of the noise floor?
Response:
What is the most cost-effective way to accurately measure the height of a ceiling when ladder use is not allowed?
You are conducting a physical site survey where heavy machinery is repaired. What is a common item required specifically for this type of survey?
During a customer walkthrough you notice an area of the CAD drawing where it is not accurate. What next step should you take?
Response:
In a large enterprise (5000+ wireless users), by what would NOT be a recommended method by which IP addresses and VLANs are assigned to
different clients associated to the same AP?
As an implementation engineer, you have just received initial design specs from a network designer for your dual-band 802.11n deployment. The
network design documents prescribe the following data rate configuration for the 2.4 GHz radio:
Basic Rates 5.5, 6, 11, 12 Mbps
Supported Rates 9, 18, 24, 36, 48, and 54 Mbps as well as MCS 0-15
What will result from this design strategy?
In an RSN requiring low-latency reassociations and no fast secure roaming protocols, what security solutions are ideal for protecting VoWiFi communication?(Choose all that apply.)
Response:
What might limit the ability to locate 802.11 clients using a WLAN infrastructure without an 802.11 tag?
