An engineer is reducing the subnet size of the corporate WLAN by segmenting the VLAN into smaller subnets. Clients will be assigned a subnet by location. Which type of groups should the engineer use to map the smaller subnets to the corporate WLAN?
WLC port groups
RF groups
AP groups
interface groups
WLAN Deployment
WLAN Location Services
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.)
Configure FlexConnect groups for each building.
Configure WMM profiles for each building.
Configure AP groups for each area type.
Configure RF profiles for each area type.
Enable DTPC on the network.

An enterprise is using two wireless controllers to support the wireless network. The data center is located in the head office. Each controller has a corporate WLAN configured with the name Copr-NET392267230WLC-1 and Corp-NET68371638WLC-2. The APs are installed using a round-robin approach to load balance the traffic. What should be changed on the cofiguration to optimize roaming?
Use the same WLAN name for the corporate network on both controllers.
Move all access points to one controller and use the other as N+1 HA.
Move the controllers to an external data center with higher internet speeds.
Place the access points per floor on the same controller.

WLC SSO is set up between two WLCs in a service provider network serving public spaces. On WLC failover, it is noticed that only about half of the original client count is now showing on the secondary WLC, although it is currently showing the role as active. Which design side case explains the issue?
The secondary WLC platform does not support the required client count.
The WLCs had not completed database sync before the primary failure.
SSO is not configured correctly.
Some client sessions were in WebAuth-Req state before failover.

APs in a remote office recently have been converted from local mode to FlexConnect to take advantage of the local switching. After the change, remote wireless users report voice quality issues and bad quality on wireless IP phones while roaming. A debug is performed, and it is noticed that the 802.11r Fast Transition is not working as expected, like on local mode AP, though the same WLAN configuration is in place. What is the cause of the issue regarding the FlexConnect APs?
They do not support 802.11r FT.
They must be added into AP groups along with a common RF profile.
They must be in a FlexConnect group to support 802.11r FT.
They must be added to AP groups to support fast roaming methods.

An engineer must decide the cell overlap for a wireless voice deployment. Which Cisco measurement recommendation should be considered?
The edge of the cell should be "67 dBm.
The edge of the cell should be below 35 RSSI.
The measurement should be done on the 2.4-GHz band.
One AP should be deployed per 3000 square feet.
