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?

Question

Options

• AUse DBCA to create a template from the existing database to contain the database structure
• BUse Database Configuration Assistant (DBCA) to create a template from the existing database
• CUse DBCA to create a template from the existing database to contain the database structure
• DCreate the database by using the CREATE DATABASE . . . command and manually import

• A
  89% (33)
• B
  3% (1)
• C
  5% (2)
• D
  3% (1)

Explanation

Option A is correct because DBCA (Database Configuration Assistant) provides a guided, automated way to create a database template from an existing production database that captures both the structure and data - producing a near-identical replica with minimal manual DBA steps. This is exactly the "minimum intervention" the question asks for, since DBCA handles file placement, initialization parameters, and configuration automatically.

Option B is a distractor that describes the same tool but omits the critical qualifier about what the template contains - without specifying that it includes the database structure (and data), it describes an incomplete action that wouldn't guarantee a proper replica. Option C is worded identically to A in this version of the question, but in the original Oracle exam context it typically refers to a structure-only template (no datafiles/data), which wouldn't be a true replica of production. Option D requires the most DBA intervention of all - manually writing a CREATE DATABASE command and importing data is time-consuming and error-prone, the opposite of what the question asks for.

Memory tip: Think DBCA = Database Clone Assistant in your mind. When you need a production replica fast with minimal effort, reach for DBCA and a template that includes both structure and data - anything manual (CREATE DATABASE, imports) = maximum effort, not minimum.
