Given: A WLAN controller is connected to ABC Company's core layer 3 Ethernet switch with an IEEE 802.1Q trunk connection. The WLAN controller's native VLAN is VLAN 6 and its IP address is 10.0.14.2 /24. Lightweight APs supporting centralized forwarding are connected to the network on VLANs 7, 8, and 9, and they each build a layer 3 tunnel back to the WLAN controller's IP address. The dynamically assigned IP addresses received by each AP from a DHCP server will be ________________.

• A.Associated with the VLAN on which they are connected.
• B.Associated with the native VLAN of the WLAN controller.
• C.Associated with VLAN 1, the default VLAN for new APs
• D.Associated with a non-routable VLAN until the MAC address of the AP is removed from the controller's MAC filter

What is a radome?

• A.A weatherproof piece of plastic covering an antenna or antenna system.
• B.The unwanted signal coverage provided by either side or back lobes in directional antennas.
• C.A piece of metal positioned behind APs mounted on outdoor poles, designed to limit the butterfly effect.
• D.A type of semi-circular ceiling found in atriums and that is a heavy cause of RF reflection.
• E.The unit used to measure the signal reflected backward by the end of a cable.

When preparing a floor plan graphic for use in predictive and manual site surveying, what calibration method will lead to the most accurate and reliable RF data?

• A.Calibrate the ceiling height of the floor plan first, then the survey software should be able to auto-calibrate the X and Y planes of the graphic.
• B.Measure the width of an actual office doorway with a tape measure and use this value to calibrate against a doorway graphic.
• C.With properly formatted .bmp and .png graphics, the site survey software should be able to extract the scale directly from the graphic data during import.
• D.Use the longest available measurement (like a straight exterior wall) to calibrate the graphic's scale.
• E.Use the known size of a small object, such as a ceiling tile, and use a single instance of this object (e.g. a single ceiling tile) to scale the floor plan.

The exhibit illustrates the azimuth and elevation for what type of antenna?

• A.10 degree vertical grid
• B.Omni-directional
• C.60 degree horizontal patch
• D.120 degree horizontal sector
• E.20 degree vertical yagi

During a post-deployment verification, you are requested to troubleshoot an area where users are experiencing poor throughput. They are using data communication only, mainly from laptops. You captured the frame displayed in the exhibit from the location where problems are reported. This frame is typical of those that were captured by the analyzer.

What does this frame reveal about the RF network in this area?

• A.Contention Free is in place in this network, which may starve some non-QoS stations from access
• B.The station that sent this frame is causing a DoS attack by using extended Duration values
• C.The AP seems to be too far to provide enough coverage to this area
• D.Stations are using null data frames as protection mechanisms to reserve the medium
• E.Multipath or excessive collisions seem to be an issue in this area
• F.One station seems to be streaming video, thus may have reserved significant bandwidth via admission control
