  • 第1题:

    以下哪些协议在IPV6中仍然可用()

    A.ICMP

    B.DHCP

    C.DNS

    D.ARP


    参考答案:A, B, C

  • 第2题:

    在IPv4向IPv6过渡的方案中,当IPv6数据报进入IPv4网络时,将IPv6数据报封装成为IPv4数据报进行传输的方案是______。

    A.双协议栈

    B.多协议栈

    C.协议路由器

    D.隧道技术


    正确答案:D
    解析:从IPv4向IPv6过渡技术主要有3种:兼容IPv4的IPv6地址、双IP协议栈和基于IPv4隧道 技术的IPv6。

  • 第3题:

    在IPv4首部中有一个“协议”字段,但在IPv6的固定首部中却没有。这是为什么?


    正确答案: 设置协议字段的目的是要告诉目的地主机把IP分组交给哪一个协议处理程序。中途的路由器并不需要这一信息,因此不必把它放在主头中。实际上,这个信息存在主头中,但被伪装了。最后一个(扩展)头的下一个头段就用于这一目的。
