350-001/CCIE Training 11

11. Refer to the exhibit. In this network, R1 is configured not to perform autosummarization within EIGRP. What routes will R3 learn from R2 through EIGRP?(350-001 Q&A)

A. 172.30.1.0/24 and 10.1.2.0/24; EIGRP only performs autosummarization at the edge between two major networks.
B. 172.30.0.0/16 and 10.1.2.0/24; R2 will perform autosummarization, although R1 will not.
C. Since R2 is configured without autosummarization, it will not propagate the 172.30.1.0/24 route.
D. 172.30.0.0/8 and 10.0.0.0/8.
Answer: A

12. Refer to the exhibit. In this network, what will be the impact at R4 if the link between R1 and R2 fails?(350-001 Q&A)

A. R3 will generate a new summary (type 3) LSA when the link between R1 and R2 fails. When R4 receives this new summary LSA, it will run SPF, recalculating its shortest path tree.
B. R4 will not receive any new LSAs of any type, nor will it run SPF.
C. R4 will receive a router (type 1) LSA from R2, since it has lost its connection to R2. When R4 receives this LSA, it will run SPF to recalculate the shortest path tree.
D. R2 will generate a new network (type 2) LSA, since it has lost its connection to 10.1.1.4/30. When R4 receives this LSA, it will run SPF to recalculate the shortest path three.
Answer: B

13. Refer to the exhibit. R7 (in Area 1) is redistributing routes that it learned from EIGRP into the OSPF process. R12 (in Area 4) receives a packet destined for a network in the EIGRP domain. What routing table entry will R12 have that will enable it to forward the packet?(350-001 Q&A)

A. the specific network entry redistributed by R7 and propagated through the OSPF domain
B. a summary route generated by R7 and propagated through the OSPF domain
C. a default route generated by R7 and propagated through the OSPF domain
D. a summary route generated by R4 and propagated to R12
E. a default route generated by R4 and propagated to R12
Answer: E

14. The Border Gateway Protocol tries to install the best path for a prefix into the Routing Information Base and fails. Which three of these are possible reasons for this failure? (350-001 Q&A)
A. memory failure
B. a route with a worse administrative distance is already present in the IGP routing table
C. a route with a better administrative distance is already present in the IGP routing table
D. the best path for the prefix is already installed in the RIB
E. the number of routes in VRF exceeds the route limit configured for the VRF instance
Answer: ACE

15. You are designing your network to be able to use trunks. As part of this process you are comparing the ISL and 802.1Q encapsulation options. All of these statements about the two encapsulation options are correct except which one?(350-001 Q&A)
A. Both support normal and extended VLAN ranges.
B. ISL is a Cisco proprietary encapsulation method and 802.1Q is an IEEE standard.
C. ISL encapsulates the original frame.
D. Both support native VLANs.
E. 802.1Q does not encapsulate the original frame.
Answer: D

16. On what type of ports would STP PortFast BPDU guard be most appropriate?(350-001 Q&A)
A. root ports
B. designated ports
C. host ports
D. alternate ports
Answer: C

17. Refer to the exhibit. This exhibit shows the NAT configuration for Router A and the output for a ping issued from device 171.68.200.48 and destined to 172.16.47.142. Based on this information, what change must be made to Router A in order for the ping to work?(350-001 Q&A)

A. reload the router
B. clear the route cache
C. add a static route
D. configure IP as classless
E. load a newer IOS image
Answer: D

18. Which of these statements about anycast RPs is correct?(350-001 Q&A)
A. Anycast RPs cannot be used in conjunction with AutoRPs.
B. After a failure of one of the anycast RPs, the PIM network will reconverge on the remaining anycast RP or RPs in less than one second.
C. After a failure of one of the anycast RPs, the PIM network will reconverge on the remaining anycast RP or RPs in roughly the same time that it takes unicast routing to reconverge.
D. The anycast RPs must reside within the same IGP domain.
Answer: C

19. Refer to the exhibit. R2 does not have any 10.100.x.x routes in either its routing table or its BGP table. What is the most likely cause of the problem?(350-001 Q&A)

A. The advertised BGP next hop is not in R2’s routing table.
B. BGP will not advertise a route that is not in the IP routing table.
C. BGP will not advertise a route unless it is synchronized with the IGP.
D. The serial link between the routers in not participating in the BGP process.
Answer: B

20. Frame Relay traffic shaping is enabled on a WAN interface with the following settings: CIR = 768 kb/s, Bc = 2000 , Be = 7680. What is the time interval Tc?(350-001 Q&A)
A. 2.6 ms
B. 10 ms
C. 7.4 ms
D. 12.6 ms
