Q11. Which two statements are true about 6to4 tunnels? (Choose two.)
Select the 2 best responses.
A. In a 6to4 tunnel, the first two bytes of the IPv6 address will be 0×2002 and the next four bytes will be the hexadecimal equivalent of the IPv4 address.
B. In a 6to4 tunnel, the first two bytes of the IPv6 address will be locally derived and the next two bytes will be the hexadecimal equivalent of the IPv4 address.
C. In a 6to4 tunnel, the IPv4 address 192.168.99.1 would be converted to the 2002:c0a8:6301::/48 IPv6 address.
D. In a 6to4 tunnel, the IPv4 address 192.168.99.1 would be converted to the 2002:c0a8:6301::/16 IPv6 address.
E. In a 6to4 tunnel, the IPv4 address 192.168.99.1 would be converted to the 2002:1315:4463:1::/64 IPv6 address.

Q14. You have implemented mutual route redistribution between OSPF and EIGRP on a border router. When checking the routing table on one of the OSPF routers within the OSPF routing domain, you are seeing some, but not all of the expected routes. Which two things should you verify to troubleshoot this problem? (Choose two.) Select 2 response(s).
A. The border router is using a proper seed metric for OSPF.
B. The border router is using a proper seed metric for EIGRP.
C. The administrative distance is set for OSPF and EIGRP.
D. The missing EIGRP routes are present in the routing table of the border router.
E. The subnet keyword on the border router in the redistribute EIGRP command.
Answer: DE

What information can you determine about this network? Select the best response.
B. The network is stable.
C. There is a flapping link or interface, and router C knows an alternate path to the network.
D. There is a flapping link or interface, and router C does not know an alternate path to the network.
E. EIGRP is not working correctly on router C.
F. There is not enough information to make a determination.

Q16. Refer to the exhibit.
It is desired to set up a BGP neighbor relationship between routers R1 and R4. BGP packets between them could travel through R2 or R3. What is the simplest configuration that will allow for failover? Select the best response.
A. Configure BGP neighbor relationships between all interfaces on R1 and R4
B. Install a direct connection between R1 and R4.
C. Configure loopback interfaces on R1 and R4 to provide the update source address for BGP packets.
D. Configure only one neighbor relationship between R1's 192.168.1.2 interface and R4's 172.16.10.2 interface.
Answer: C
Q17. When an OSPF design is planned, which implementation can help a router not have memory resource issues? Select the best response.
A. Have a backbone area (area 0) with 40 routers and use default routes to reach external destinations.
B. Have a backbone area (area 0) with 4 routers and 30,000 external routes injected into OSPF.
C. Have less OSPF areas to reduce the need for interarea route summarizations.
D. Have multiple OSPF processes on each OSPF router. Example, router ospf 1, router ospf 2.
Answer: A
Q18. Refer to the exhibit.
Based on the command output, what is one reason why no routes from the OSPF neighbor 192.168.0.5 are installed in the IP routing table?
Select the best response.
A. R3 will only install routes from the neighbor with the lowest priority (Pri). If routes have the same priority, routes from the neighbor with the lowest IP address are used.
B. R3 did not receive any LSAs from 192.168.0.5.
C. Routes from backup designated routers are never installed in the IP routing table.
D. 192.168.0.5 is a redundant link to 192.168.0.4, and load balancing is not enabled.
Answer: B
Q19. In which state do DR and BDR establish adjacency with each OSPF router in the network?
