Question 36

A network engineer observes a spike in controller CPU overhead and overall network utilization after multicast is enabled on a controller with 500 APs. Which feature corrects the issue?

  1. controller IGMP snooping
  2. multicast AP multicast mode
  3. broadcast forwarding
  4. unicast AP multicast mode

Question 37

An engineer is configuring multicast for wireless for an all-company video meeting on a network using EIGRP and BGP within a single domain from a single source. Which type of multicast routing should be implemented?

  1. Protocol Independent Multicast Dense Mode
  2. Source Specific Multicast
  3. Multicast Source Discovery Protocol
  4. Protocol Independent Multicast Sparse Mode

Question 38

Which statement about the VideoStream/Multicast Direct feature is true?

  1. IP multicast traffic is reliable over WLAN by default as defined by the IEEE 802.11 wireless multicast delivery mechanism.
  2. Each VideoStream client acknowledges receiving a video IP multicast stream.
  3. It converts the unicast frame to a multicast frame over the air.
  4. It makes the delivery of the IP multicast stream less reliable over the air, but reliable over Ethernet.

Question 39

Which configuration is applied to prevent the network from a Layer 2 flooding of multicast frames with a seamless transfer of multicast data to the client when roaming from one controller to another?

  1. Enable IGMPv3 on the central Layer 3 switch.
  2. Enable IGMP snooping on the WLC.
  3. Enable multicast mode on the WLC.
  4. Create multicast groups on the central Layer 3 switch.

Question 40

An engineer is configuring multicast for two WLCs. The controllers are in different physical locations and each handles around 500 wireless clients. How should the CAPWAP multicast group address be assigned during configuration?

  1. Each WLC must be assigned a unique multicast group address.
  2. Each WLC management address must be in the same multicast group.
  3. Both WLCs must be assigned the same multicast group address.
  4. Each WLC management address must be in a different multicast group.
