If another path advertises the 6.6.6.0/24 path and has the default local preference, that path is morepreferred.B. The command neighbor send-community is configured on BGP neighbor 10.10.23.3.C. The route 10.10.23.3 is not being advertised to other BGP neighbors.D. Route 6.6.6.0/24 is learned by an IBGP peer.Answer: B2. If no metric is specified for the routes being redistributed into IS-IS, what metric value is assigned to theroutes?Select the best response.A. 0B. 1C. 10D. 20Answer: A3. Refer to the exhibit. Which three statements accurately describe the result of applying the exhibitedroute map? (Choose three.)Select 3 response(s).A. The map prohibits the redistribution of all type 2 external OSPF routes with tag 6 set.B. The map prohibits the redistribution of all type 2 external OSPF routes.C. The map redistributes into EIGRP all routes that match the pfx prefix list and the five metricvalues40000, 1000, 255, 1, and 1500.D. The map prohibits the redistribution of all external OSPF routes with tag 6 set.E. All routes that do no match clauses 10 and 20 of the route map are redistributed with their tags set to 8.F. The map permits the redistribution of all type 1 external OSPF routes.Answer: AEF4. Refer to the exhibit. EIGRP has been configured on all routers in the network. What additionalconfiguration statement should be included on router R4 to advertise a default route to its neighbors?Select the best response.A. R4(config)# ip default-network 10.0.0.0B. R4(config)# ip route 0.0.0.0 0.0.0.0 10.1.1.1C. R4(config)# ip route 10.0.0.0 255.0.0.0 10.1.1.1D. R4(config-router)# default-information originateAnswer: A5. Into which two types of areas would an area border router (ABR) inject a default route? (Choose two.)Select 2 response(s).A. the autonomous system of a different interior gateway protocol (IGP)B. area 0C. totally stubbyD. NSSAE. stubF. the autonomous system of an exterior gateway protocol (EGP)Answer: CE6. Which three restrictions apply to OSPF stub areas? (Choose three.)Select 3 response(s).A. No virtual links are allowed.B. The area cannot be a backbone area.C. Redistribution is not allowed unless the packet is changed to a type 7 packet.D. The area has no more than 10 routers.E. No autonomous system border routers are allowed.F. Interarea routes are suppressed.Answer: ABE7. Refer to the exhibit. Which two statements are true about the partial configuration that is provided.(Choose two.)Select 2 response(s).A. All the configured neighbors are in autonomous system 100.B. The peer group shortens the IBGP configuration.C. The peer group shortens the EBGP configuration.D. Only the outgoing filters are applied to BGP updates.E. Three AS-path filters are applied to each BGP neighbor.Answer: AB8. Refer to the exhibit. Which two statements are correct? (Choose two.)Select 2 response(s).A. All six routes will be installed in the routing table.B. Two routes will be installed in the routing table.C. Four routes will be installed in the routing table.D. All the routes were redistributed into BGP from an IGP.E. All the routes were originated by BGP with the network command.Answer: CD9. Which three IP multicast related statements are true? (Choose three.)Select 3 response(s).A. Multicast addresses 224.0.1.0 through 238.255.255.255 are called globally scoped addresses. Theyare used to multicast data between organizations and across the Internet.B. The multicast address 224.0.0.1 is a globally scoped address that has been reserved for the NetworkTime Protocol (NTP) by the IANA.C. Multicast addresses 239.0.0.0 through 239.255.255.255 are called limited scope addresses. They areconstrained to a local group or organization.D. Multicast addresses 224.0.0.5 and 224.0.0.6 are limited scoped addresses that have been reserved forOSPF.E. Multicast addresses 224.0.0.0 through 224.0.0.255 are used for network protocols on local LANsegments. Because they are always transmitted with a Time to Live (TTL) of 1, they are never forwardedby a router.Answer: ACE10. Which three IP multicast address related statements are true? (Choose three.)Select 3 response(s).A. Multicast addresses 224.0.0.0 through 224.0.0.255 are always forwarded because they are transmittedwith Time to Live (TTL) greater than 1.B. Multicast addresses 224.0.0.5 and 224.0.0.6 are source multicast addresses for OSPF routers.C. Multicast addresses 224.0.0.13 and 224.0.0.22 are reserved link-local addresses used by PIMv2 andIGMPv3.D. Because they would map to overlapping IP multicast MAC addresses, multicast addresses 224.0.1.1and 238.1.1.1 could not be used together.E. Multicast address 224.0.1.1 has been reserved for the Network Time Protocol (NTP) by the IANA.F. The administratively scoped multicast addresses 239.0.0.0 through 239.255.255.255 are similar inpurpose to RFC 1918 private unicast addresses.Answer: CEF有需要的朋友自己下载(PDF格式)
