Refer to the exhibit． A junior network administrator was given the task of configuring port security on SwitchA to allow only PC_A to access the switched network through port fa0/1． If any other device is detected, the port is to drop frames from this device． The administrator configured the interface and tested it with successful pings from PC_A to RouterA, and then observes the output from these two show commands．
Which two of these changes are necessary for SwitchA to meet the requirements?

【正确答案】
1、B,D
【答案解析】题目大意是说在交换机A上端口f0/1上配置端口安全，目的是只允许 PC_A连接网络,其他设备连接上将被丢弃,并且PCA可以ping通RA,问在swa上必须改变的哪两个配置？
考点分析：一般端口安全是在接口下配置的。如题，只允许PC_A连接交换机的Fa0/1口，所以应该限制接口所允许的最大MAC地址数为1，即答案为BD。
