A network administrator notices that a new video conferencing application is being reported as 'unknown' in AVC reports. The application is not in the current NBAR2 database. What should the administrator do to ensure the application is correctly classified?

Reboot the wireless controller to refresh the application database.

Enable AVC on the WLAN and wait for the controller to learn the application automatically.

Update the NBAR2 application database on the controller to the latest version.

Manually create a custom ACL to match the application's IP addresses.

A retail company wants to ensure that point-of-sale (POS) traffic receives priority over video streaming on their guest WLAN. They are considering enabling AVC to achieve this. What is the primary benefit of using AVC in this scenario?

AVC increases the wireless throughput for all clients on the WLAN.

AVC allows the controller to identify applications and apply QoS policies based on that identification.

AVC automatically blocks all video streaming traffic to free bandwidth.

AVC eliminates the need for QoS configuration on the WLAN.

A network engineer is troubleshooting why a custom application is not being classified by AVC on a Cisco 9800 controller. The application uses a well-known port but with a proprietary protocol. The engineer has already created a custom NBAR2 application definition. What is the next step to verify the classification?

Disable and re-enable AVC on the WLAN.

Change the WLAN QoS profile to Platinum.

Check the AVC statistics for the client to see if the custom application appears.

Reboot the controller to load the custom definition.

A Cisco Catalyst 9800 controller has AVC enabled globally and on a WLAN. An AVC profile that polices video streaming to 1 Mbps is applied to the WLAN. Users report that video streaming is not being limited. Which two checks should you perform first?

Change the WLAN QoS profile to Platinum and verify the client's IP address.

Verify that the AVC profile is applied to the WLAN and that the video traffic is being classified correctly.

Reboot the access points and check the controller logs.

Disable and re-enable AVC globally and on the WLAN.

Which two configuration steps are required to enable AVC on a Cisco wireless network?

Enable AVC globally on the controller and then enable AVC on each WLAN

Configure AVC on the switch and then apply it to the WLAN

Enable AVC on the access points and then configure the application database

Enable AVC on the WLAN and then reboot the controller
