An engineer must create data link redundancy for the company's Cisco Wireless LAN controller.
The engineer has decided to configure LAG-based redundancy instead of port-based redundancy.
Which three features of LAG-based redundancy influenced this decision? (Choose three.)

An engineer must deploy a wireless network in an open-plan environment that has three SSIDs using the 5 GHz band and the channel width is set to 40 MHz. Co-channel interference must be reduced. Which two actions must be taken? (Choose two.)

An engineer is performing an AP-on-a-stick survey and finds that the 5 GHz channel overlap is too high when an appropriate number of APs are used for the density requirements. Which two actions during the survey reduce channel overlap? (Choose two.)

An engineer is setting up the WLC to support a high-density design for a lecture hall. The engineer must modify the existing high-density RF profile to obtain a smaller cell size. Also, the clients must connect to the nearest AP using the highest possible data rates. Which setting allows this design?

An engineer designed a new wireless network for an enterprise customer. The customer is concerned that some wireless features may not be available because the bill of materials has only Base and no WPlus licenses for the Cisco WLC version 8. What is the reason for the engineer to take this approach regarding the licenses?
