  • 第3题:

    ICMP协议属于TCP/IP网络中的 ( ) 协议,ICMP报文封装在 (请作答此空) 包中传送。

    A.IP
    B.TCP
    C.UDP
    D.PPP

    答案:A
    解析:
    Internet控制报文协议(Internet Control Message Protocol,ICMP)是TCP/IP协议簇的一个重要协议,属于网络层,用于在IP主机、路由器之间传递控制消息。控制消息是指网络通不通、主机是否可达、路由是否可用等网络本身的消息。这些控制消息虽然并不传输用户数据,但是对于用户数据的传递起着重要的作用。该协议属于网络层协议,ICMP报文是封装在IP数据报内传输。
