An administrator applies an AVC profile to a WLAN that marks video streaming with DSCP AF41. After testing, the client's video traffic is still marked with DSCP 0. The client is using a wired connection to an access point in flexconnect mode. What is the most likely reason?

The client's operating system is overriding the DSCP marking.

AVC policies are not supported for locally switched traffic on flexconnect APs.

The video streaming application is not recognized by NBAR2.

The AVC profile is not applied to the WLAN.

A user reports that a specific application is not being marked with the expected DSCP value even though the AVC policy is configured. The administrator verifies that AVC is enabled globally and on the WLAN. What should the administrator check next?

Verify that the application is correctly classified by NBAR2 using the 'show avc application' command.

Check the AP's radio channel configuration for interference.

Reboot the wireless controller to apply the policy.

Confirm that the client's device has the correct IP address.

A network admin notices that AVC reports show 'unknown' for a well-known application that should be recognized. The controller has the latest signature package. What is the most likely cause?

The access points are not rebooted after signature update.

The WLAN QoS profile is set to Platinum.

The application uses a non-standard port or protocol that NBAR2 cannot match.

A manager wants to see which applications are being used on the wireless network right now, including top talkers. AVC is enabled on all WLANs. What is the quickest way to view this information?

Use the controller's AVC dashboard or 'show wireless client avc statistics' command.

Generate a report from Cisco Prime Infrastructure.

Use the WLAN's QoS profile settings.

Check the access point's local logs.

Where is AVC enabled on a Cisco wireless LAN controller to apply to a specific wireless network?

In the access point configuration under the Advanced tab

In the global wireless settings under the RF tab

In the security settings under the AAA tab

In the WLAN configuration under the QoS tab

Part of the QoS on a Wireless Network domain, which accounts for 10% of the 300-430 exam. Cisco does not publish an official question count, but from its 90-minute exam (~35–60 total, ~4–6 in this domain), expect 1–2 from this objective — we provide 35 practice questions to prepare you well beyond it.
