                                          Question #2

                                          A network engineer draws a schematic diagram of a multicast network (shown in the figure) during troubleshooting. R1 and R2 run IGMP version 2 and use PIM-SM as the multicast routing protocol. The default settings are used for other parameters. Given this, the DR on the multicast network is _____. (Enter the device ID, for example, R1.)

                                          Correct Answer:

                                          R2
                                          Explanation:
                                          PIM Sparse Mode (PIM-SM) elects a Designated Router (DR) on a shared network segment to coordinate multicast source registration and receiver-side multicast forwarding.
                                          The election first compares the DR priorities advertised in PIM Hello messages.
                                          The router with the highest DR priority is selected. When routers have equal priorities, the router with the numerically highest interface IP address wins.
                                          In the topology, R1 uses 10.0.12.1/24 and R2 uses 10.0.12.2/24. Both routers use default DR priority values.
                                          Because 10.0.12.2 is higher than 10.0.12.1, R2 is elected as the PIM-SM Designated Router.
                                          This differs from the IGMPv2 querier election, which selects the router with the lowest IP address. Thus, R1 would be the IGMP querier, but R2 is the PIM-SM DR.

                                          Question #3

                                          R1 forwards a packet with the destination IP address of 4.4.4.4 on an MPLS network.
                                          * Some LSP (Label Switched Path) information of R3 is shown in the figure.
                                          * During packet transmission, which of the following devices perform MPLS label operations?

                                          • A. R3
                                          • B. R4
                                          • C. R2
                                          • D. R1

                                          Question #4

                                          On a PIM-SM multicast network, a network engineer finds that multicast clients cannot receive multicast data. Which of the following is not a possible cause of this problem?

                                          • A. The RP addresses of multicast devices are different.
                                          • B. Downstream interfaces of multicast devices are disabled from forwarding State-Refresh messages.
                                          • C. The downstream interfaces of multicast devices do not receive any (*, G) Join messages.
                                          • D. The unicast routes from multicast devices to the RP are unavailable.

                                          Question #5

                                          RD and RT are introduced to BGP/MPLS IP VPN networks. Which of the following statements are true about RD and RT?

                                          • A. A VPNv4 address is 96 bits long, and an RD is 64 bits long.
                                          • B. A VPNv4 route can contain only one RD and one RT.
                                          • C. An RD is added in front of an IPv4 address to resolve IPv4 address conflicts.
                                          • D. An RD is not used to identify the origin of a route or determine the VPN instance to which the route should be added.
