An engineer has been tasked with optimizing roaming for all the wireless networks used by shops located in a shopping center. A unique WLAN is assigned to each individual shop named ret470632970B55XX, where the last two digits indicate the shop's location. The wireless network consists of 9800 controllers and Cisco 9100 APs. What should the engineer configure on the controllers to optimize roaming?

A network has two Cisco WLCs and two Layer 3 gigabit Ethernet switches. The customer requires two gigabit connections from each Cisco WLC to each of the switches that have copper RJ-45 gigabit ports. What two additional hardware are needed to connect the Cisco WLCs to the network? (Choose two.)

A wireless engineer must optimize RF performance for multiple buildings with multiple types of construction and user density. Which two actions must be taken? (Choose two.)

An engineer is performing an active survey of a network that must support different types of mobile devices. The devices must be able to run an application that requires a minimum RF of 73 dBm. Which mobile device must be used for the survey?

An engineer configured the optimized client roaming on Cisco WLC with an RSSI threshold of
72dBm. Clients report frequent disconnections. What must be configured for the AP to guide the client to a better AP?
