Oracle Database 12c: Installation and Administration — Question 154

You plan to create a database by using the Database Configuration Assistant (DBCA), with the following specifications:
Applications will connect to the database via a middle tier.
The number of concurrent user connections will be high.
The database will have mixed workload, with the execution of complex BI queries scheduled at night.
Which DBCA option must you choose to create the database?

Answer options

• A. a General Purpose database template with default memory allocation
• B. a Data Warehouse database template, with the dedicated server mode option and AMM enabled
• C. a General Purpose database template, with the shared server mode option and Automatic Memory Management (AMM) enabled
• D. a default database configuration

Correct answer: C

Explanation

The correct answer is C because a General Purpose database template with shared server mode and AMM is ideal for handling a high number of concurrent connections and mixed workloads. Option A does not support high concurrency effectively, while option B is more suited for data warehouses focused on large-scale analytics, and option D lacks specific configurations necessary for the outlined requirements.
