  2. B
    bronze
  3. C
    platinum
  4. D
    silver

Correct Answer: D ?️

Question #32
An engineer wants to configure WebEx to adjust the precedence and override the QoS profile on the WLAN. Which configuration is needed to complete this task?
  1. A
    Change the WLAN reserved bandwidth for WebEx
  2. B
    Create an AVC profile for WebEx
  3. C
    Create an ACL for WebEx
  4. D
    Change the AVC application WebEx-app-sharing to mark

Correct Answer:
B

Question #33
All APs are receiving multicast traffic, instead of only the APs that need it. What is the cause of this problem?
  1. A
    The multicast group includes all APs
  2. B
    The wrong multicast address was used
  3. C
    The multicast group is assigned the wrong VLAN
  4. D
    Multicast IGMP snooping is not enabled

Correct Answer:
D

Question #34
What is the difference between PIM sparse mode and PIM dense mode?
  1. A
    Sparse mode supports only one switch. Dense mode supports multiswitch networks.
  2. B
    Sparse mode floods. Dense mode uses distribution trees.
  3. C
    Sparse mode uses distribution trees. Dense mode floods.
  4. D
    Sparse mode supports multiswitch networks. Dense mode supports only one switch.

Correct Answer:
C

Question #35
An engineer has been hired to implement a way for users to stream video content without having issues on the wireless network. To accomplish this goal, the engineer must set up a reliable way for a Media Stream to work between Cisco FlexConnect APs. Which feature must be enabled to guarantee delivery?
  1. A
    Unicast Direct
  2. B
    IGMP Direct
  3. C
    Multicast Direct
  4. D
    Multicast-to-Unicast Direct

Correct Answer:
C

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. A
    controller IGMP snooping
  2. B
    multicast AP multicast mode
  3. C
    broadcast forwarding
  4. D
    unicast AP multicast mode

Correct Answer:
B

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. A
    Protocol Independent Multicast Dense Mode
  2. B
    Source Specific Multicast
  3. C
    Multicast Source Discovery Protocol
  4. D
    Protocol Independent Multicast Sparse Mode

Correct Answer:
D

Question #38
Which statement about the VideoStream/Multicast Direct feature is true?
  1. A
    IP multicast traffic is reliable over WLAN by default as defined by the IEEE 802.11 wireless multicast delivery mechanism.
  2. B
    Each VideoStream client acknowledges receiving a video IP multicast stream.
  3. C
    It converts the unicast frame to a multicast frame over the air.
  4. D
    It makes the delivery of the IP multicast stream less reliable over the air, but reliable over Ethernet.

Correct Answer:
B

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. A
    Enable IGMPv3 on the central Layer 3 switch.
  2. B
    Enable IGMP snooping on the WLC.
  3. C
    Enable multicast mode on the WLC.
  4. D
    Create multicast groups on the central Layer 3 switch.

Correct Answer:
B

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

Correct Answer:
A
