Refer to the exhibit. All routers on this network have been configured with PIM-SM, and R1 is the rendezvous point. However, when asymmetric routing is implemented to modify link usage, the network begins to drop certain multicast traffic. Which action corrects the problem?

  1. Place the routes affected by asymmetric routing in a VRF
  2. Remove the asymmetric routing and use spanning tree to manage link usage
  3. Add a static mroute for routes that are failing
  4. Configure the routers to use PIM-DM instead of PIM-SM

Answer(s): C



An engineer is troubleshooting slow performance issues on a customer’s network after the last multicast configuration change was applied on it. While checking the running configuration on the router, the engineer notices there are many ipigmp join-group commands applied on several interfaces of the router which caused the high CPU utilization usage. What action must the engineer take to solve this issue?

  1. Configure all router interfaces to be process-switched by increasing the query interval
  2. Remove ipigmp join-group command on all unnecessary interfaces
  3. Remove unnecessary members from the IGMP group
  4. Configure ipigmp static-group command on all interfaces

Answer(s): B



Refer to the exhibit. A customer reports that Host-1 is failing to receive streaming traffic from the IPTV source. The engineer has confirmed that hosts on router R2 are receiving traffic normally and that Host-1 is correctly sending subscription messages to join the IPTV stream. Which action must the engineer take to correct the problem?

  1. Remove IP PIM SSM and IGMP from interface GigabitEthernet 1/0/1 on R3 and configure under global configuration
  2. Configure IGMP version 3 under interface GigabitEthernet 1/0/1 on R3
  3. Configure IP PIM SSM and IGMP version 2 under interface GigabitEthernet 1/0/1 on R3
  4. Remove IP PIM SSM from the global configuration on R3 and configure it under the GigabitEthernet 1/0/1 interface

Answer(s): B



Refer to the exhibit.


Router R1 is configured to advertise outgoing SA messages to routers R2 and R3, but to receive incoming SA messages only from R2. Which additional configuration must an engineer apply to router R1 so it filters all MSDP SA messages from Domain-C?

  1. R1# ipmsdpsa-filter in 192.168.3.1
  2. R3# ipmsdpsa-filter out 192.168.3.1
  3. R3# ipmsdp password peer 192.168.1.1
  4. R1# ipmsdp password peer 192.168.3.1

Answer(s): A



What is the difference between a source tree and a shared tree in a multicast environment?

  1. To route traffic from source to receiver a source tree uses a link-state routing protocol and a shared tree uses a distance-vector routing protocol.
  2. A source tree has its root at the source, and a shared tree has its root at a designated rendezvous point.
  3. To stream multicast from source to receiver, a source tree uses PIM-SM and a shared tree uses PIM-DM.
  4. Source trees are the default type for bidirectional PIM, and PIM-DM uses shared trees by default.

Answer(s): B
