300-360 Question #258: Real Exam Question with Answer & Explanation

You have been contacted by an existing Cisco wireless networking customer. The Big Oil Service Company wants to expand their Wi-Fi network outside their facility to their Pipe and Fittings Yard. The customer is in the oil field services business and provides consumable products to the oil drilling industry. The customer has been using hand-held scanners on their fleet of order- processing vehicles to ensure that the correct parts are collected for each order. The issue that the customer is experiencing is that the processing of customer orders is taking an excessive amount of time. Each time a new order is received, a paper pull-ticket is physically handed to the operator of an order- processing vehicle. If the specific vehicle cannot pull all the components of a customer order, they must physically hand-off the paper pull-ticket to another order-processing vehicle for completion. After the operator scans the parts to complete the order, they must drive back to the warehouse office to download the order information from the hand-held scanners into the order processing terminals. The current hand- held scanner can process only one order at a time. The company is upgrading to new scanners that operate in the 2.4 GHz spectrum and can process multiple orders simultaneously without any paper forms. The company wants you to validate a design that their internal IT staff has created for the Pipe and Fittings Yard. (See the enclosed Conceptual Network Diagram and a Proposed AP Placement Diagram of the Big Oil Services Company facility.) The Pipe and Fitting Yard has lights for operation at night. The lights are attached to the side of the Warehouse and Fabrication building and are on 40 foot concrete poles out in the yard and all the lights have 110V power. The RAP location is on the side of the Warehouse and Fabrication building below the roof line and just below the exterior light on the side of the building. The RAP will draw power from this light and will have a fiber optic connection back to a switch in the MDF in the office building. All the MAPs will be attached to the light poles in various locations around the Pipe and Fittings Yard. (See enclosed Proposed AP Placement Diagram.) MAP 5 has four possible paths to the RAP. The first path is through MAP 7 that has a SNR of 120 dB and an EASE of 212418 and a connection to MAP 6 with an SNR of 120 dB and an EASE of 212418 and a connection to the RAP that has a SNR of 120 dB and an EASE of 212418. The second path is through MAP 4 that has a SNR of 78 dB and an EASE of 477846 and a connection from MAP 4 to the RAP that has a SNR of 78 dB and an EASE of 477846. The third path is through MAP 3 that has a SNR of 78 dB and an EASE of 386212 and a connection to MAP 4 that has a SNR of 78 and an EASE of 477846 and a connection to the RAP with a SNR of 78 dB and an EASE of 386212. The fourth path is through MAP 6 that has a SNR of 120 dB and an EASE of 212418. Which option is the parent MAP and what is the corrected EASE? (Choose two.)
