Exhibit A -
Exhibit B -
A customer wants to deploy 12 FortiAP 431F devices on high density conference center, but they do not currently have any PoE switches to connect them to. They want to be able to run them at full power while having network redundancy.
From the FortiSwitch models and sample retail prices shown in the exhibit, which build of materials would have the lowest cost, while fulfilling the customer’s requirements?
To run the FortiAP 431F devices at full power, each AP requires a Power over Ethernet (PoE) power budget of 24.5 W (as indicated by the maximum power consumption spec). Therefore, for 12 APs, the total power requirement is 12 x 24.5 W = 294 W. The FortiSwitch 124E-FPOE provides a PoE power budget of 370 W, which is sufficient to support all 12 APs without exceeding its capacity. Additionally, using two FortiSwitch 124E-FPOE units will provide network redundancy. The combined cost for two FortiSwitch 124E-FPOE units ($1,250 each) is lower than the cost of alternative configurations that also meet the power requirements. This makes option D the lowest-cost solution that fulfills the customer's requirements.
124E is cheaper compare to 224E
224E power budget is 180 W and requirement of 12 AP is around 250 watts
D is correct the access point will require about 24.5 W of power and the 124E-FPOE has a Capacity of about 370 meaning 25x12 = 300 so you left with about 70 W on the switch meaning you can still add two more access point on that switch.
B is correct, since you can power the FAP with 2x802.3af (15w) ports at full power. If you connect one port to each switch from each AP you get redundancy and full power with 180w for 12 ports with the cheaper 224E poe. The cost is in the input diagram and it says 224E poe is cheaper than 124F FPOE
B. Split the APs to two FortiSwitch 224E-POE and this also provides network redundancy at cheaper cost.
