解析:
trace命令是一个用来查询网络上数据流向的理想工具,它采用与ping命令相同的技术,用于跟踪测试分组转发路径的每一步。从trace命令跟踪的结果可以了解路径上每一级路由器的工作状况、延迟时间等。如果路径中任何一台路由器是不可达的,则显示三个星号“***”,用星号取代路由器名。此时,trace命令将继续尝试到达下一步,直到使用Ctrl+ Shift+F6退出。

单选题In your test database, you find that a user’s session is executing a lot of SQL statements, resulting in the generation of a large number of trace files.
