Case Study a Customer Needs a Wireless Network Upgrade for 802.11ac

Case study A customer needs a wireless network upgrade for 802.11ac and possibly an upgrade to the wired network. The customer requires dual-radio 802.11ac APs, each radio of which can support 4x4 MIMO at full feature set. The customer has given architects this information about their wireless devices: 2700 IoT devices which will have only wireless connections; they support WPA2 with 802.1X 300 on each floor in 3 buildings with 3 floors each 5,400 users, who use devices such as laptops and smartphones 600 users on each floor in 3 buildings with 3 floors each 24 security cameras which will have only wireless connections; they support WPA2 with 802.1X and have a local power source 4 on floor 1 of each of the 3 buildings 2 on the other 6 floors T he architect also has collected information about the existing wired network. The existing access layer switches support these features: 10/100/1000 edge ports PoE (802.3af) 1GbE fiber uplinks The existing aggregation switches support these features: 1/10GbE fiber ports ARP tables up to 62,000 The customer has provided this figure that shows the existing cabling between floors and between buildings: Each floor is about 100 feet (30 m) by 140 feet (43 m) with a 10 foot (3 m) ceiling. Interior walls are drywall. The layout for each floor is similar to that shown below. CAT5e cable is extended to all areas. What is one piece of additional information architects should obtain from the customer before they design the wireless solution?

A) whether the users sometimes connect their laptops with Ethernet
B) whether the IoT devices support MAC-Auth
C) the number of concurrently used wireless devices per user
D) the power requirements for the security cameras
