300-410 Part 01 Q15 010

Which of the following statements is TRUE about the given set of commands?

  • IPv4 and IPv6 are running simultaneously on rtrA
  • The IPv4 address is translated to an IPv6 address
  • The IPv6 address is an IPv4-compatible address
  • A tunnel is created for the interoperability of the IPv4 and IPv6 addresses
Explanation:
The correct answer is that IPv4 and IPv6 are running simultaneously on rtrA. The set of commands enables IPv6 on the rtrA router and assigns an IPv4 address and an IPv6 address to the Fa0/0 interface. This indicates that the router is a dual-stack router on which both IPv4 and IPv6 are running simultaneously.The IPv4 address is not translated to the IPv6 address by the given set of commands because NAT-PT is not enabled on the router. To enable NAT-PT on a router, you need to use the ipv6 nat command. In addition, the ipv6 nat prefix command should be used to specify an IPv6 prefix.The IPv6 address is not an IPv4-compatible address. IPv4-compatible IPv6 addresses are used in automatic IPv4-compatible IPv6 tunnels. These addresses refer to those IPv6 unicast addresses that have zeros in the first 96 bits and an IPv4 address in the last 32 bits. For example, 0:0:0:0:0:0:192.156.10.67 is an IPv4-compatible IPv6 address where 192.156.10.67 is an IPv4 address. The IPv6 address (2001:0:1:1:D52::F3C/64), in this case, is not an IPv4-compatible IPv6 address.A tunnel is not created for the interoperability of the IPv4 and IPv6 addresses because the given set of commands configures the router as a dual-stack router. There are no commands for configuring a tunnel on the router.
