You must propose an Oracle Data Guard configuration for a database supporting a DSS workload that meets these permanent requirements:
1. The performance impact on the primary database should be kept to a minimum.
2. Creating and maintaining materialized views should not impact the performance of the primary database.
Additionally, there are these requirements, only the one of which is ever done at any one time:
3. It should be possible to apply designated patches with a minimum amount of downtime.
4. Upgrading to a new database release should be performed with the least possible amount of downtime.
5. New application software releases should be tested against an exact up-to-date replica of the production database.
You propose a configuration operating in Maximum Performance mode with a primary database and one logical standby database.
Which requirements do you meet?
- A. 2 and 5
- B. 1, 2, and 3
- C. 1 and 5
- D. 1, 2, 3, 4, and 5
