With respect to address summarization, which of the following statements concerning IPv4 and IPv6 is true?
The correct answer is B. Role based addressing using wildcard masks to match multiple subnets is suitable for IPv4, but. For IPv6 access lists, the wildcard masks are not usually used. All source and destination addresses are notated in the form of prefixes. Therefore, it is important that subnets that are to be grouped in an access list falling within a summarized address range.
Question
With respect to address summarization, which of the following statements concerning IPv4 and IPv6 is true?
Options
- AThe potential size of the IPv6 address blocks suggests that address summarization favors IPv6
- BRole based addressing using wildcard masks to match multiple subnets is suitable for IPv4, but
- CIn order to summarize, the number of subnets in the IPv4 address block should be a power of 2
- DWAN link addressing best supports summarization with a /126 subnet for IPv4 and a /31 for IPv6.
