QUESTION 284

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

A.       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.

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.

Answer: AC

QUESTION 285

A network administrator is managing a hub-and-spoke network with EIGRP routing that has been enabled. The hub router is trying to query a remote router.

A.       Configure the hub router with a scope limit of 1.

B.       Configure the remote router with a scope limit of 1.

C.       Configure the hub to indicate that the remote router is a stub router.

D.      Configure the hub and remote router as stub routers.

E.       Configure the remote router as a stub router.

F.        Disable the SIA feature of EIGRP on the remote router.

Answer: E
