  • 第3题：

    Anytime a host or a router has an IP datagram to send to another host or router, it has the（　）address of the receiver. This address is obtained from the DNS if the sender is the host or it is found in a routing table if the sender is a router. But the IP data gram must be（　） in a frame to be able to pass through the physical network. This means that the sender needs the （　）address of the receiver. The host or the router sends an ARP query packet. The packet includes the physical and IP addresses of the sender and the IP address of the receiver. Because the sender does not know the physical address of the receiver, the query is（　） over the network.Every host or router on the network receives and processes the ARP query packet, but only the intended recipient recognizes its IP address and sends back an ARP response packet.The response packet contains the recipient's IP and physical addresses. The packet is（请作答此空） directly to the inquirer by using the physical address received in the query packet.

    A. multicast
    B. unicast
    C. broadcast
    D. multiple unicast

    答案：B
    解析：
    任何时候主机或路由器要发送 IP 数据报发送给另一主机或路由器时，都需要知道接收方的逻辑地址。发送主机从 DNS 获得该地址，发送路由器则在路由表中找到该地址。但 IP 数据报必须封装在帧中才能通过物理网络。这意味着发送者需要知道接收者的物理地址。主机或路由器需发送 ARP 查询报文，该报文分组包含发送者的物理地址和 IP 地址及接收者的 IP 地址。这是因为送者不知道接收者的物理地址，所以需在全网广播报文。网络上的每个主机或路由器都能接收并处理该 ARP 查询报文，但只有预期的接收者识别其 IP 地址并响应该 ARP 报文。响应报文包含接收者的 IP 地址和物理地址。包含了接收者物理地址的响应报文分组通过单播的方式直接发送给发送者。
