An enterprise h as plans to start adding IPv6 support. For the first year, the IPv6 will be in small pockets spread around the existing large IPv4 network, with occasional IPv6 traffic while applications teams test IPv6 - enabled servers and applications.
Which of the fol lowing tools would be most appropriate?（）
A. Native IPv6
B. Point - to -point tunnels
C. Multipoint tunnels
D. NAT - PT
A. Metric
B. Administrative distance
C. Timeout (seconds)
D. Prefix length
E. Interface ID
The following output occurs on Router R1 , which runs both EIGRP for IPv6 and OSPFv3, with redistribution from EIGRP into OSPF configured with the redistribute eigrp 1 metric 25 command. Interface S0/0/1 has been enabled for EIGRP ASN 1. Which of the following should be true of redistribution in this case?（）

C 2000:0:0:1::/64 [0/0]

A. Route 2000::/64 will be redistributed.
B. Route 2 000:0:0:1::/64 will be redistributed.
C. Route 2000:1:213:19FF:FE7B:5004/128 will be redistributed.
D. No routes will be redistributed because of the omission of the subnets parameter of the redistribute command.
Router R1 currently has no configuration related to IPv6 or IPv4. The following configuration exists in a planning document, intended to be used to copy/paste into Router R1 to enable OSPFv3 on interfaces F0/0 and S0/0/0. No other related configuration exists. Assuming F0/0 and S0/0/0 reach an up/up state, which of the following is true about OSPFv3 on R1 after this configuration has been pasted into R1?（）

ipv6 ospf 1 area 1
interface s0/0/0

A. OSPF works on F0/0 and S0/0/0 without further configuration
B. OSPF works with the addition of one command: a no shutdown command in OSPF router configur ation modE
C. OSPF works with the addition of one command: an router - id command in OSPF router configuration modE
D. OSPFv3 needs at least two more configuration commands before it works on R1
A. The method of choosing an OSPF router ID
B. Verification checks that must be validated before two routers can become OSPF neighbors
