Refer to the exhibit. Two ISPs have decided to use MSDP and configured routers X and Y (both are PIM RPs) as MSDP peers. In the domain of ISP B, PC A has sent an IGMP membership report for the group 224.1.1.1 and PC B has sent an IGMP membership report for the group 224.5.5.5. Assuming that the MSDP peering relationship between routers X and Y is functional, and given the partial configuration output shown from router X, which two of these statements are true?（）

A.Router X will contain an entry for 224.1.1.1 in its SA cache and will also have an installed （S，G） entry for this in its mroute table.
B.Router X will not contain an entry for 224.1.1.1 in its SA cache but will have an installed （*，G） entry for this in its mroute table.
C.Router X will not contain an entry for 224.5.5.5 in its SA cache but will have an installed （S，G） entry for this in its mroute table.
D.Router X will not contain an entry for 224.5.5.5 in its SA cache but will have an installed （*，G） entry for this in its mroute table.
E.Router X will have no entries for 224.5.5.5 in neither its SA cache nor in its mroute table.
F.Router X will have no entries for 224.1.1.1 in neither its SA cache nor in its mroute table.

单项选择题WhichstatementbestdescribesOSPFexternalLSAs（type5）？（）

A.OSPF external LSAs are automatically flooded into all OSPF areas， unlike type 7 LSAs， which require that redistribution be configured.
B.External LSAs （type 5） are automatically changed to type 1 LSAs at ASBRs.
C.Type 5 LSAs are route summaries describing routes to networks outside the OSPF Autonomous System.
D.External network LSAs （type 5） redistributed from other routing protocols into OSPF are not permitted to flood into a stub area.

A.Each interface has a different OSPF cost.
B.Each interface is configured with secondary addresses as well as primary addresses.
C.Each interface has a different MTU size.
D.Each interface is configured with theip unnumbered loopback 0 command.

单项选择题Refer to the exhibit. Router E learned about the PIM RP （designated as 7.7.7.7） from four different sources. Routers A and D advertised the 7.0.0.0 network via EIGRP. Routers B and C advertised the 7.0.0.0 network via OSPF. Considering that all four Ethernet interfaces on router E could potentially lead back to the PIM-RP， when router E receives the first multicast packet down the shared tree， which incoming interface will be used to successfully pass the RPF check？（）

A.E0
B.E1
C.E2
D.E3
E.None of these interfaces will be used to successfully pass the RPF check
F.All of these interfaces would successfully pass the RPF check

单项选择题On the basis of the network provided in the exhibit， all routers are configured to run EIGRP on all links. If the link between PG-R1 and PG-R2 fails， what is the maximum number of queries PG-R3 will receive for 192.168.1.0 24， assuming that all the packets sent during convergence are transmitted once （there are no dropped or retransmitted packets）？（）

A.PG-R3 will receive up to four queries for 192.168.1.0/24， one each from PG-R2， PG-R4， PGR5，and PG-R6.
B.PG-R3 will receive up eight queries for 192.168.1.0/24， one from PG-R2， two from PG-R4，three from PG-R5， and four from PG-R6.
C.PG-R3 will receive one query for 192.168.1.0/24， since the remote routers， PG-R4， PG-R5， and PG-R6， are natural stubs in EIGRP
D.PG-R3 will not receive any queries from PG-R2， because there are no alternate paths for 192.168.1.0/24.
