71.Based on the output provided in the exhibit, to which address or location will the router forward a packet sent to 192.168.32.1?
A. 10.1.1.1 B. 10.1.1.2 C. 10.1.1.3 D. The default gateway
Answer: A
72.Based on the exhibit presented. PG-R2 does not have any 10.100.x.x routes in either its routing table or its BGP table. What will you do at PG-R5 to solve this problem?
A. Disable BGP synchronization. B. Set the BGP next-hop-self command for neighbor PG-R2 C. Configure a static route for 10.100.0.0/16 to null0 D. Add a BGP network statement to encompass the serial link.
Answer: C
73.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.
Answer: A
74.You are a network engineer at PassGuide.com, study the exhibit carefully. The company's network is running EIGRP and you want to change the path PG-R5 uses to reach 172.30.1.0/24 to PG-R4. How could you achieve this goal? 更改路径，使得 R5 到 172.30.1.0/24 走 R4
A. Change the bandwidth on the link between PG-R2 and PG-R5 to 70, and change the bandwidth on the link between PG-R3 and PG-R5 to 70. B. Change the bandwidth on the link between PG-R4 and PG-R5 to 110. C. Change the bandwidth on the link between PG-R3 and PG-R5 to 70. D. Donothing, the best path to 172.30.1.0/24 from PG-R5 is already through PG-R4.
Answer: A
75.On the basis of the network provided in the exhibit, R3 and R4 are configured to run all connected links in OSPF Area 1. The network administrator is complaining that traffic destined to 192.168.1.0/24 is being routed to R2, even if R2 is not running OSPF. Which would be the cause of this problem? 基于提供的网络图，R3和R4都配置了OSPF在区域1，网络管理员抱怨流量指定到 192.168.1.0/24是走路由器R2，尽管R2没有运行OSPF。什么原因导致这个问题？
A. The next hop towards 192.168.1.0/24 at PG-R4 should be 10.1.1.2, which is PG-R2. B. The next hop towards 192.168.1.0/24 at PG-R4 should be 10.1.1.1, since PG-R1 is redistributing the route from EIGRP into OSPF. PG-R3 is forwarding traffic incorrectly. C. The next hop towards 192.168.1.0/24 at PG-R4 should be 10.1.2.2, which is PG-R3. PGR3 should be load-sharing between PG-R1 and PG-R2 for its next hop. D. PG-R4 does not have a route towards 192.168.1.0/24, so the network administrator is wrong in thinking any traffic is being forwarded there.
Answer: A
