Which three approaches can be used while migrating from an IPv4 addressing scheme to an IPv6 scheme (choose three)
A.
static mapping of IPv4 address to IPv6 addresses
B.
configuring IPv4 tunnels between IPv6 islands
C.
use DHCPv6 to map IPv4 addresses to IPv6 addresses
D.
use proxying and translation (NAT-PT) to translate IPv6 packets into IPv4 packets
E.
configure IPv6 directly
F.
enable dual-stack routing
B, D and F are correct
Thanks.
Correct answers are A, B, D, F. Answer A is also correct. Static IPv6 mappings to IPv4 addresses can configured with a NAT64 approach. See more here: http://www.cisco.com/en/US/prod/collateral/iosswrel/ps6537/ps6553/white_paper_c11-676278.html
While A is correct it is not the preferred method as it is highly time consuming and does not scale.
A, B, D, F is correct but in a large network, static mapping between ipv4 and ipv6 consume much more time, and in case of any minor mistake, you will be stuck in troubleshooting.
that’s why B,D,F is the recommended way to of migration.
Thanks for reading this post.
