A client reports that video is not streaming. The administrator determines the client is connecting at a data rate of 12 Mbps and is trying to stream to a valid multicast address on the network. What three items should the administrator check next to troubleshoot the issue? (Choose three)
- A. IGMP snooping is turned off because the client cannot request to join a group, only access points can.
- B. Video-stream for the multicast video is configured in the controller.
- C. WLAN has been set for a QoS value of Platinum.
- D. WLAN has been configured to allow multicast-direct to work correctly and multicast- direct has been enabled globally.
- E. WLAN has been set for a QoS value of Gold.
- F. RTSP is used to stream the video due to wireless multicast not using acknowledgements.
Answer : B,D,E
Which two methods to discover a controller does a MAP attempt when it boots up?
(Choose two.)
- A. |f Ethernet and wireless are available, it attempts to discover only via Ethernet.
- B. if Ethernet is disconnected, it attempts to connect wirelessly using AWPP.
- C. if only wireless is available and it is configured as a MAP, it does not attempt to connect to a WLC.
- D. If Ethernet and wireless are available, it uses Ethernet first. If it cannot connect via Ethernet, then it chooses wireless.
- E. |f Ethernet is disconnected, it attempts to connect wirelessly using the configured DHCP option.
Answer : A,B

- B. When only WMM is enabled, information element number 3 QBSS Load information element is sent out in the beacons and probe responses.
- C. When the client CAC limit is supported, information element number 2 is sent out in the beacons and probe responses on the bg radios.
- D. When the client CAC limit is supported, information element number 1 is sent out in the beacons and probe responses on the bg radios.
- E. When only WMM is enabled, information element number 2 QBSS Load information element is sent out in the beacons and probe responses.
Answer : D,E

Answer : B,E
A downstream packet containing a DSCP value arrives at the WLC Ethernet interface from the wired source network. The WLC is configured for QoS WLAN 802.1p mapping. How does the WLC treat the CAPWAP QoS marking when leaving the controller interface for the respective AP and final wireless client destination?
- A. No outer CAPWAP or inner QoS tagging is applied.
- B. No outer CAPWAP QoS tag is applied, but the original DSCP is maintained inside CAPWAP.
- C. The outer CAPWAP CoS is marked and capped while the inner DSCP maintains the original marking.
- D. The outer CAPWAP DHCP is marked and capped without any inner DSCP value.
Answer : C

- E. Disable DHCP server override.
Answer : A,E
Refer to Exhibit.
A wireless client is connecting to FlexAPI which is currently working standalone mode. The
AAA authentication process is returning the following AVPs:

VLAN(13)
Which three behaviors will the client experience? (Choose three.)
- A. While the AP is in standalone mode, the client will be placed in VLAN 15.
- B. While the AP is in standalone mode, the client will be placed in VLAN 10.
- C. When the AP transitions to connected mode, the client will be de-authenticated.
- D. While the AP is in standalone mode, the client will be placed in VLAN 13.
- E. When the AP is in connected mode, the client will be placed in VLAN 13.
- F. When the AP transitions to connected mode the client will remain associated.
- G. When the AP is in connected mode, the client will be placed in VLAN 15.
- H. When the AP is in connected mode, the client will be placed in VLAN 10.
Answer : A,D,E
A customer recently implemented WLC wireless multicast. Clients and connecting at the highest mandatory wireless rate of 24 Mbps and are receiving multicast traffic, but WLC cpu utilization and wired side network load has increased substantially. What three actions should the engineer take next to optimize the configuration? (Choose Three)
- A. verify that Global Multicast mode has been enabled
- B. verify that IGMP snooping is disabled on the wireless controller since the access points are handing IGMP messages from the clients.
- C. make sure the highest mandatory rate is set to 54 Mbps so that the multicast traffic has sufficient bandwidth
- D. verify Multicast Listener Discovery (MLD) v1 snooping has been enabled to keep track of and deliver IPv4 multicast flows
- E. change the wireless controller from Multicast-Unicastmodeto Multicast-Multicast mode and assign a multicast address in the 239.X.X.X/8 subnet
