在一台Cisco路由器上执行show access-lists命令显示如下一组限制远程登录的访问控制列表信息
Standard IP access list 40
permit 167.112.75.89 (54 matches)
permit 202.113.65.56 (12 matches)
deny any (1581 matches)
根据上述信息，正确的access-list的配置是（）。
A．Router (config) #access-list 40 permit 167.112.75.89
Router (config) #access-list 40 permit 202.113.65.56
Router (config) #access-list 40 deny any
Router (config) #line vty 0 5
Router (config-line) #access-class 40 in
B．Router (config) #access-list 40 permit 167.112.75.89 log
Router (config) #access-list 40 permit 202.113.65.56 log
Router (config) #access-list 40 deny any log
Router (config) #line vty 0 5
Router (config-line) #access-class 40 in
C．Router (config) #access-list 40 permit 167.112.75.89 log
Router (config) #access-list 40 permit 202.113.65.56 log
Router (config) #access-list 40 deny any log
Router (config) #line vty 0 5
Router (config-line) #access-class 40 out
D．Router (config) #access-list 40 permit 167.112.75.89
Router (config) #access-list 40 permit 202.113.65.56
Router (config) #access-list 40 deny any log
Router (config) #line vty 0 5
Router (config-line) #access-class 40 out
参考答案：A
解析：
根据配置标准访问控制列表的命令格式“access-list access-list-number {permit | deny}source wildeard-mask”可知，B、C明显错误，D选项“access-list 40 deny any”后面不用加log。
