Which two statements are true about 6to4 tunnels? (Choose two.)

• A.In a 6to4 tunnel, the IPv4 address 192.168.99.1 would be converted to the 2002:c0a8:6301::/16 IPv6 address.
• B.In a 6to4 tunnel, the IPv4 address 192.168.99.1 would be converted to the 2002:1315:4463:1::/64 IPv6 address.
• C.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.
• D.In a 6to4 tunnel, the IPv4 address 192.168.99.1 would be converted to the 2002:c0a8:6301::/48 IPv6 address.
• E.In a 6to4 tunnel, the first two bytes of the IPv6 address will be 0x2002 and the next four bytes will be the hexadecimal equivalent of the IPv4 address.

The company and the company network have both been growing rapidly. Multiple adds, moves and changes have been applied to the network. Your boss has asked you to troubleshoot a recent OSPF synchronization problem that has arisen. There have been synchronization problems at separate locations in the OSPF area 0. There have been reported link failures during the rapid growth of the company network. You are required to resolve the OSPF problem. OSPF must be able to converge when the network changes.
Refer to the information above to answer the following question.

Refer to the exhibit. On the basis of the output from the show ipv6 interface command, what two statements must be true? (Choose two.)

• A.The IP address of the designated router (DR) is FE80::A8BB:CCFF:FE00:6E00.
• B.This is the designated router (DR) on the Ethernet 0/0 link.
• C.Interface Ethernet 0/0 was configured with the ipv6 ospf 1 area 1 command.
• D.OSPF version 3 is enabled to support IPv6.
• E.Interface Ethernet 0/0 has been configured with the ipv6 ospf authentication ipsec spi 500 md5 command.

Refer to the exhibit. A new TAC engineer comes to you for advice. The engineer wants to configure RIPv2- OSPF two-way redistribution while avoiding routing loops.
Which two additions to the router B1 configuration should the engineer make? (Choose two.)

During the redistribution process configured on RTA, some of the EIGRP routes, such as 10.1.1.0/24 and 10.2.2.0/24, are not being redistributed into the OSPF routing domain.

Which two items could be a solution to this problem? (Choose two.)

• A.Change the EIGRP AS number from 100 to 1 in the redistribute command.
• B.Add the subnets option to the redistribute command.
• C.Configure the redistribute command under router eigrp 1 instead.
• D.Change the metric to an EIGRP compatible metric value (bandwidth, delay, reliability, load, MTUs) in the redistribute command.
• E.Change the metric-type to 2 in the redistribute command.
