If there are multiple receivers in a multicast group, the administrator enables IGM on the switch connecting the receiversP Snooping function, when the receiver changes from When the switch receives the general group query message from the querier, how should multiple receivers respond?

• A.The first receiver whose response time times out is sentReport messages are not sent by other receivers.
• B.All recipients will respondReport message
• C.Only run ICMPv2, all receivers will respond to the Report message.
• D.Only when IGMPvI is running will all receivers respondReport message.

The following is about the PIM-SMRegister message description is correct? ( confirmed)

• A.The Register message is sent by the source DR
• B.The Register message is sent by the receiver router
• C.The Register message is sent to the RP via unicast instead of multicast
• D.The Register message enables the RP to learn the multicast source information

As shown in the figure, a company has built an OSPF network. The links in the figure all form an OSPF adjacency relationship, and all OSPF devices announce their own loopback interface addresses. One day, the two links of S1-R2 and S2-R1 suddenly failed. In order to check whether the network is running normally, the engineer checked the equipment status. Which of the following descriptions is correct?

• A.R3 cannot learn the loopback route of R2
• B.R5 can learn the loopback route of R2 normally
• C.R3 can learn the loopback route of R2 normally
• D.R1 can normally learn the loopback route of R2

As shown in the figure, which of the following options can satisfy two routers to establish an ISIS neighbor relationship?

• A.ISIS with two routersProcess IDs must be the same.
• B.Both routers remain the default type.
• C.Both routers are Level-1type.
• D.One of the two routers can be a Level-1-2 type, and the other can be a Leve1-1 type.

RTA is the source DR router and RTB is the RP router. The multicast source sends multicast data to the RIA, but the RIB cannot see the multicast source registered to it through the PIM Register message. What are the possible reasons?

• A.The RP is statically configured on the multicast network, while the RTA router is not statically configured with the RP
• B.The multicast network dynamically elects RP, and RTA fails to check the RPF of BSR.
• C.The RP elected by RTA is not RTB
• D.There is no unicast route from RTB to RTA, which causes RTB to fail the RPF check of the source.
