Which QoS level is recommended for guest services?

  • A. gold
  • B. bronze
  • C. platinum
  • D. silver


Answer : B

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?

  • A. Change the WLAN reserved bandwidth for WebEx
  • B. Create an AVC profile for WebEx
  • C. Create an ACL for WebEx
  • D. Change the AVC application WebEx-app-sharing to mark


Answer : B

All APs are receiving multicast traffic, instead of only the APs that need it. What is the cause of this problem?

  • A. The multicast group includes all APs
  • B. The wrong multicast address was used
  • C. The multicast group is assigned the wrong VLAN
  • D. Multicast IGMP snooping is not enabled


Answer : D

What is the difference between PIM sparse mode and PIM dense mode?

  • A. Sparse mode supports only one switch. Dense mode supports multiswitch networks.
  • B. Sparse mode floods. Dense mode uses distribution trees.
  • C. Sparse mode uses distribution trees. Dense mode floods.
  • D. Sparse mode supports multiswitch networks. Dense mode supports only one switch.


Answer : C

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?

  • A. Unicast Direct
  • B. IGMP Direct
  • C. Multicast Direct
  • D. Multicast-to-Unicast Direct


Answer : C

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?

  • A. controller IGMP snooping
  • B. multicast AP multicast mode
  • C. broadcast forwarding
  • D. unicast AP multicast mode


Answer : B

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?

  • A. Protocol Independent Multicast Dense Mode
  • B. Source Specific Multicast
  • C. Multicast Source Discovery Protocol
  • D. Protocol Independent Multicast Sparse Mode


Answer : D

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

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


Answer : B

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?

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


Answer : B

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?

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


Answer : A

A wireless network has been implemented to enable multicast video to be streamed reliably over the wireless link to the wireless users. After a client reports that the video is unable to stream, the administrator determines that the client is connecting at a data rate of 12 Mbps and is trying to stream to a valid multicast address on the network. Which two actions must be applied? (Choose two.)

  • A. Turn off IGMP snooping for all the configured WLANs on the controller.
  • B. Implement video-stream for the multicast video on the controller.
  • C. Allow multicast-direct to work correctly and multicast-direct to be enabled globally.
  • D. Change the WLAN QoS value to Bronze for the WLAN that multicast will be enabled.
  • E. Allow RTSP to stream the video due to wireless multicast not using acknowledgements.


Answer : BC

Which two restrictions are in place with regards to configuring mDNS? (Choose two.)

  • A. mDNS uses only UDP port 5436 as a destination port.
  • B. mDNS cannot use UDP port 5353 as the destination port.
  • C. mDNS is not supported on FlexConnect APs with a locally switched WLAN.
  • D. Controller software must be newer than 7.0.6+.
  • E. mDNS is not supported over IPv6.


Answer : CD

A network engineer needs to configure multicast in the network. The implementation will use multiple multicast groups and PIM routers. Which address provides automatic discovery of the best RP for each multicast group?

  • A. 224.0.0.13
  • B. 224.0.0.14
  • C. 224.0.1.39
  • D. 224.0.1.40


Answer : D

A shopping center uses AireOS controllers with Cisco Wave 2 APs. A separate WLAN named Guest-012345678-WLAN is used for guest wireless clients.
Management needs location analytics to determine popular areas. CMX must track only associated clients. What must be selected on the CMX server settings?

  • A. Exclude probing clients
  • B. Duty Cycle Cutoff
  • C. Enable Locally Administered MAC Filtering
  • D. Enable Location MAC Filtering


Answer : A

A wireless engineer needs to implement client tracking. Which method does the angle of arrival use to determine the location of a wireless device?

  • A. received signal strength
  • B. triangulation
  • C. time distance of arrival
  • D. angle of incidence
