During the deployment of a WLAN, the use of specialized helper applications is indispensible. These hardware components and computer programs allow the deployment engineer to visualize the invisible energy patterns that compose the RF channels. Which of the following best describes a specialized application that allows the deployment engineer to gather OSI Model Layer 1 and Layer 2 activity, in real time, and model the combined effects, superimposed on a representative background image?

• A.Spectrum Analyzer
• B.WLAN Discovery tool
• C.Manual Site Survey tool
• D.Predictive Site Survey tool
• E.Protocol Analyzer

Which of the following frame types are used during 802.11 associations?

• A.Encrypted frames
• B.Management frames
• C.Protection frames
• D.Control frames
• E.Data frames

Which of the following is the single biggest security vulnerability evident in the image below?

• A.Use of Netgear and Motorola APs on the same RF bands
• B.Use of Pre-Shared Key on several WLANs
• C.Use of Temporal Key Integrity Protocol on WLAN1a
• D.Use of no security on Visitor VLAN
• E.Use of Counter Mode with Cipher Block Chaining Message Authentication Code Protocol on several WLANs
• F.Use of Wired Equivalent Privacy on WLAN1g

You are positioning an AP on the 4th floor of a multi floor building. The site survey indicated that there are concrete floors, a concrete block wall on one side of the room, and a sheetrock wall on the other end of that room. Which of these obstacles will attenuate the signal the most?

• A.Depends on how close the AP is to each item
• B.Concrete cinder block wall
• C.The sheetrock wall
• D.Concrete floors at each level

You have upgraded an existing WLAN by replacing the existing autonomous dual-band APs with RFS controllers and thin dual-band 802.11n APs, You have created two Local VLANs and configured the next-hop Ethernet ports to use the same VLAN configurations. During testing you are able to connect successfully to either VLAN but you are not able to PING from the first VLAN to the second VLAN. Which of the following is one possible reason for this condition?

• A.No default gateway has been assigned to the client device associated with the Local VLAN
• B.The Local VLAN has not been configured on every access point
• C.There is no Layer 2 switch connecting the two VLANs
• D.DHCP services have been configured for both Local VLANs
