You want to create a test database as a replica of your production database with minimum intervention from a DBA.
Which method would you use?
A) Use DBCA to create a template from the existing database to contain the database structure with data files and then use the same template to create the database in the new location.
B) Use Database Configuration Assistant (DBCA) to create a template from the existing database to contain the database structure.
C) Use DBCA to create a template from the existing database to contain the database structure and then manually copy the data by using Oracle Data Pump.
D) Create the database by using the CREATE DATABASE . . . command and manually import data by using Data Pump.
Answer：A
(解析：DBCA可以基于当前的数据库创建一个数据库模版，然后根据这个模版创建一个与当前数据库一样新的数据库。)
