95. You have a large amount of historical data in a flat file. Some analysts in your organization need to query this data in the file. The file is too large to load the data in it into your current database.

Which is the most effective method to access this data in your database?

A.Use the database link.

B.Use the SQL*Loader utility.

C.Use the Oracle Data Pump utility.

D.Create an external table and leave the data in the flat file.

Answer: D

答案解析：

BC不对，题中说文件太大，不能加载到数据库，A也不对，这是一个平面文件，不是数据库文件，不能通过dblink来访问。

所以只能使用外部表来访问。
