A wired packet that is marked for QoS priority CS4 arrives on VLAN-4 at Cisco WLC v7.0, with a destination of a WLAN SSID-4. The Cisco WLC is configured for the wired and
wireless QoS level of Silver. The infrastructure routers and switches have incorrect QoS configurations. They have mismarked the CAPWAP outer header to a QoS priority EF.
Which statement is true about how the packet is sent from the AP to the final WMM wireless client?

• A.The AP sends the packet with an 802.11 priority tag of 5 (Gold).
• B.The AP sends the packet with an 802.11 priority tag of 0 (Best Effort).
• C.The AP sends the packet with an 802.11 priority tag of 3 (Silver).
• D.The AP sends the packet with an 802.11 priority tag of 6 (Platinum).

You have recently enabled multicast on your WLAN. When users join the multicast sessions, you see the traffic utilization on all the APs that are controlled by the Cisco WLC v7.0 increase, which includes those APs where there are no multicast clients.
Which configuration parameter needs to be verified to prevent APs with no subscribed multicast clients from receiving traffic?

• A.The Cisco WLC is not configured for IGMP snooping.
• B.Switches between the Cisco WLC and APs are not configured for IGMP snooping.
• C.The router interface that services the multicast needs to be configured for the sparse-dense multicast mode of operation.
• D.APs are not configured for IGMP snooping.
• E.This is normal operation and cannot be changed.

Refer to the exhibit.

What two items of multicast information can be interpreted from the WLC display? (Choose two.)

• A.IGMP snooping is disabled.
• B.VideoStream is allowed for the wireless client.
• C.VideoStream is not allowed for the wireless client.
• D.WLC-to-AP multicast mode is configured for Unicast.
• E.IGMP snooping is enabled.
• F.WLC-to-AP multicast mode is configured for multicast.

What happens to a wireless client when it moves from one controller to another in a different mobility domain?

• A.It is not possible to roam to a different mobility domain.
• B.The client will have to reauthenticate and reassociate, but will be able to keep its IP address information.
• C.The client will have to reauthenticate, reassociate, and get new IP address information.
• D.Nothing happens as long as the client roams within the same mobility group.

Refer to the exhibit.

An engineer notices VoWLAN calls getting dropped and uses Spectrum Expert to analyze the RF utilization. Based on the Spectrum Expert capture, what two options describe the interferer and how to mitigate it? (Choose two.)

• A.DECT 6.0 Cordless phone interference
• B.Radar interference
• C.Disable RRM
• D.Bluetooth interference
• E.Disable DCA
• F.Disable DFS
• G.microwave oven interference
• H.Disable UNII-2 channels
