An engineer uses two routers to test Pv6 services, and runs OSPFV3 to implement the interconnection of IPv6 networks. R1 is required to be able to access the loopback interface address of R2. The engineer checked the OSPFv3 routing table entry of R1 and found that there was no route to the loopback interface address of R2. Which of the following reasons could not be the cause? A. R2 does not have OSPFv3 enabled on the loopback interface B. R2 does not use network to advertise the loopback address in area 0 C. R2 advertises the loopback interface into different OSPFv3 processes D. R2 is not configured with the Router ID used in the OSPFv3 process Answer: B Download valid H12-261_V3.0 Practice Exam From PassQuestion 6. Configure filter-policy 2000 export in the IS-IS process. Which statement is wrong about the function of this command? A. It needs to be used in conjunction with route import to advertise only part of the imported external routes to neighbors B. If this command is not configured, the device will advertise all routes imported from the external routing protocol to IS-IS by default. C. It will restrict the routing entries generated by the device itself from publishing to the outside world D. This command will filter the link status information published externally Answer: D Download valid H12-261_V3.0 Practice Exam From PassQuestion 7. Which of the following description is correct about the functional of SSM? A. Using SSM, the receiver can use INCLUDE in IGMPv3 to indicate the source he wishes to join B. SSM is an extension to the DVMP protocol to efficiently transmit one- to-many communication traffic C. SSM requires MSDP to discover active sources in other PIM domains D. Routing multicast traffic in SSM relies on the number of sources, and RP is used for the receiver to reach the corresponding source number Answer: A Download valid H12-261_V3.0 Practice Exam From PassQuestion 8. Which of the following options is correct? (Multiple choice) A. Unicast and broadcast cannot effectively realize data transmission between one source and multiple destinations on P2MP, but multicast technology can achieve B. Multicast technology can reduce redundant traffic, so it can save network bandwidth C. Multicast technology for "one-to-many" applications D. Since multicast establishes connections based on TCP, multicast technology can ensure reliable data transmission Answer: BC Download valid H12-261_V3.0 Practice Exam From PassQuestion 9. Why is BGP an enhanced distance vector routing protocol? A. According to the route selection rules of BGP routes, the route with the lower MED is preferred B. BGP uses the AS PATH attribute to record all the autonomous system numbers experienced by the route into an AS list, and selects routes according to this attribute, preferring the route with a shorter AS-PATH C. NEXT_HOP is a recognized mandatory attribute D. BGP cannot accept routes with local AS numbers in AS_PATH Answer: B Download valid H12-261_V3.0 Practice Exam From PassQuestion 10.
