问题 下列哪一个IP地址是不可能存在的?
选项 A.192.163.0.2 B.256.134.7.8 C.201.202.34.9 D.136.64.17.5
答案 B
解析 IP地址范围要在因是要在0.0.0.0到255.255.255.255之间,B选项256超过了255的范围,所以该选项说法错误。

Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.
