第2题:

Which two statements are true about using IPv4 and IPv6 simultaneously on a network segment? ()

  • A、IPv6 allows a host to create its own IPv6 address that will allow it to communicate to other devices on a network configured via DHCP. IPv4 does not provide a similar capability for hosts.
  • B、IPv6 provides for more host IP addresses but IPv4 provides for more network addresses.
  • C、Hosts can be  configured to receive both IPv4 and IPv6 addresses via DHCP.
  • D、Host configuration options for IPv4 can be either statically assigned or assigned via DHCP.Host configuration options for IPv6 can be statically assigned only.
  • E、IPv4 and IPv6 addresses c an be simultaneously assigned to a host but not to a router interface.

正确答案:A,C

第10题:

实现IPv4到IPv6的过渡技术主要有


正确答案: (1)双栈策略:在IPv6结点中加入IPv4协议栈,这些结点既可以收发IPv4分组,也可以收发IPv6分组。
(2)隧道技术:利用穿越现存IPV4因特网的隧道技术将许多个“IPV6孤岛”连接起来,逐步扩大IPV6的实现范围。
(3)TB(隧道代理):简化隧道的配置,提供自动的配置手段。
(4)双栈转换机制:实现新的IPv6网络与现有的IPv4网络之间的互通。
(5)协议转换技术:在V6节点与V4节点的通信时借助于协议转换服务器把网络层协议头进行V6/V4间的转换来解决V4节点与V6节点互通的问题。
