Refer to the exhibit．Switch-1 needs to send data to a host with a MAC address of 00b0．d056．efa4．What will Switch-1 do with this data?
【正确答案】
B
【答案解析】没有mac地址会泛红。
根据下图，Switch-1需要往一台MAC地址为00b0．d056．efa4的主机发数据，Switch-1会如何处理这些数据?
A． Switch-1 will drop the data because it does not have an entry for that MAC address．(Switch-1会丢弃该数据，因为它没有该MAC地址条目)
B． Switch-1 will flood the data out all of its ports except the port from which the data originated．(Switch-1会泛洪该数据到所有的接口，除了该数据的源接口)
C． Switch-1 will send an ARP request out all its ports except the port from which the data originated．(Switch-1会发送ARP请求到所有的接口，除了该数据的源接口)
D． Switch-1 will forward the data to its default gateway．(Switch-1会往默认网关发送该数据)
