第2题：

A client/server application has been configured to use local naming. The client and server run on separate machines. When the client tries to connect， it receives a TNS error. By carefully examining the environment， a tnsnames.ora is found only on the Oracle server machine， among other things. After copying this tnsnames.ora onto the client machine， the client is able to connect to the server.  Which statement is true？（）
