An enterprise is using a Cisco AireOS controller and Wi-Fi 6 APs. The controller is installed in the head office, and the employees primarily use Apple OS devices. The APs broadcast WLAN ENT-WLAN406558520-1 for the employees and a guest WLAN with similar naming. What needs to be enabled on the controller to optimize roaming?
Aggregated Probe Response Optimization
Fast SSID Changing
Load Balancing Window
Client Timers

A customer has determined that aesthetics is a primary concern for their upcoming guest deployment. Which design consideration can be leveraged to address this concern?
Paint the access point to cover the LED from being noticeable.
Use enclosures to hide the wireless infrastructure in the surrounding environment.
Use AIR-AP-BRACKET-1 to allow for greater mounting locations
Deploy environmentally friendly cabling components to blend into the environment.

Which two considerations must a network engineer have when planning for voice over wireless roaming? (Choose two.)
Full reauthentication introduces gaps in a voice conversation.
Roaming time increases when using 802.1x + Cisco Centralized Key Management.
Roaming occurs when the phone has seen at least four APs.
Roaming occurs when the phone has reached "80 dBs or below.
Roaming with only 802.1x authentication requires full reauthentication.

An engineer is designing a new wireless network. The network needs to meet these requirements:
• support a high wireless client concentration
• support data over wireless
• support voice over wireless
• avoid interference
Which design approach should be taken?
• support a high wireless client concentration
• support data over wireless
• support voice over wireless
• avoid interference
Which design approach should be taken?
5 GHz frequency band with channel bonding, to support 40 MHz channels
5 GHz frequency band without channel bonding, to support 20 MHz channels
2.4 GHz frequency band without channel bonding, to support 20 MHz channels
5 GHz frequency band with channel bonding, to support 80 MHz channels
