You are managing a wireless access point in autonomous mode using the Web based interface. You capture traffic during this management task and notice that you can see the HTML code of the Web pages for access point management. What error in administration could be the cause of the security concern?

You are deploying a WLAN with the access points configured for 10 mW of output power on the 2.4 GHz radios and 20mW of output power on the 5GHz radios. Some semi-directional antennas are also in use. What kind of deployment is described?

You recently purchased four laptops containing dual-band 802.11ac adapters. The laptops can connect to your 2.4 GHz network, but they cannot connect to the 5 GHz network. The laptops do not show the 5 GHz SSIDs, which are different that the 2.4 GHz SSIDs. Existing devices can connect to the 5 GHz SSIDs with no difficulty. What is the likely problem?

What security solution is deprecated in the 802.11 standard and should never be used in any modern WLAN deployment?

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?

An RF sigma sometimes bends as it passes through some material other than free space. What is the term that describes this behavior?

As an RF wave propagates through space, the wave front experiences natural expansion that reduces its signal strength in an area. What term describes the rate at which this expansion happens?
