cisco ccna automation.9. ao does not have the command ip nat outside configured on interface seriall/0±, so no address translation will take place. B, C, and D are not correct answers because the translation is incorrectly configured.10.CoACLs are processed before the other three. A is incorrect because the policy routing is executed after the inbound rate limiting policy; B is incorrect because the internal-to-external NAT rule is executed after the policy routing; and D is incorrect because the inbound rate limiting policy is executed after the inbound ACL.Chapter 23IPv623.01 The Need for IPv6 23.05 Routing and IPv6 23.02 IPv6 Addressing 23.06 Configuring IPv6 23.03 IPv6 Improvements Two-Minute Sprint 23.04 Address Assignment Self-Test QuestionsThis chapter introduces the next generation of TCP/IP: IP version 6 (IPv6). o In light of the numerous shortcomings of IPv4 and its poor scalability for hierarchical addressing, IPv6 was developed to meet the rapidly growing needs of small companies and the explosive expansion of Intemet, especially in emerging markets such as China and India. This chapter explores the need for IPv6, various IPv6 addresses, IPv6 routing, and basic IPv6 configuration. The CCNP certification course discusses IPv6 in much greater depth than this chapter oCertification Objectives 23.023.1 The Need for IPv6IPv4 addresses are 32 bits long, and the actual number of addresses is 232,or 4.3 billion. But not all of these addresses are available-only 3.7 billion are available, because many are reserved, such as addresses used for research (prefixed with 239.254), broadcast addresses (prefixed with 255), multicast addresses (prefixed with 224.239), private addresses (prefixed with 10, 172.16, or 192.168-headed addresses), and loopback addresses (127-headed). Of course, many of the available addresses have already been assigned, and there are very few available for expansion.Unlike IPv4 addresses, which are 32 bits long, and IPv6 addresses, which are 128 bits long, this provides 3.4x1038 addresses, which is a lot of addresses to apportion to each person, even if the population grows several times.
