You have been asked to use a convention that allows for auto configuration of interface addresses. You are not allowed to use DHCPv6. What do you do?
Click on the arrows to vote for the correct answer
A. B. C. D.B
The correct answer is D. Use an IPv6 static configuration.
IPv6 supports stateless address autoconfiguration (SLAAC) which allows a host to automatically configure its own address using information advertised by a router on the network. However, this requires the use of DHCPv6 for providing additional configuration parameters such as DNS server addresses and domain names.
Option A, using IPv4 with the autoconfig option under family inet, is not applicable in this case as it is an IPv4-only feature and does not address the requirement for IPv6 autoconfiguration.
Option B, using IPv6 in the network to configure hosts, is also not the best answer as it is not clear what specific method of IPv6 autoconfiguration is being referred to. SLAAC, as mentioned earlier, requires the use of DHCPv6 for additional configuration parameters, while DHCPv6 itself is explicitly disallowed in the question.
Option C, using a program (e.g. Vector-Wiz) to autoconfigure IP addresses, is not a standard solution and may not be compatible with existing network devices and protocols. It is also not clear what this program is and how it works, which makes it difficult to evaluate its suitability.
Option D, using an IPv6 static configuration, is a viable solution that provides predictability and control over the assigned addresses. With static configuration, the administrator manually assigns the addresses to the interfaces, which eliminates the need for DHCPv6 or SLAAC. This method is also more secure than SLAAC as it prevents unauthorized devices from joining the network.
In summary, the best answer to the question is D. Use an IPv6 static configuration.
