• Question 337:

  Refer to exhibit. The dynamic interfaces shown above are bound to an interface group for a specific WLAN profile in the Cisco Wireless LAN Controller. You notice duplicated multicast streams on the wireless medium for the given WLAN profile. Which statement is correct?

  

  A. The controller always uses Layer 3 multicast group ID for all Layer 3 multicast traffic sent to the access point. Internet Group Management Protocol snooping should be disabled to avoid duplicate streams.
  B. The controller creates different multicast group IDs for each multicast address and VLAN, and as a result, the upstream router sends one copy for each VLAN. Enable Multicast VLAN to avoid duplicate streams.
  C. Global multicast mode and Internet Group Management Protocol snooping have not been enabled. To avoid duplicate streams, enable both.
  D. Global multicast mode, global IPv6 config, and multicast listener discovery snooping have not been enabled. Enable these to avoid duplicate streams.
  A. The controller always uses Layer 3 multicast group ID for all Layer 3 multicast traffic sent to the access point. Internet Group Management Protocol snooping should be disabled to avoid duplicate streams.
