Oracle Cloud Infrastructure 2019 Developer Associate — Question 153

Your company is developing a new database application in Oracle Cloud Infrastructure. You need to test application functionality including a hardware failure scenario. Since the application is still in the development phase, you want to minimize infrastructure costs.
Which database service deployment option meets this requirement?

Answer options

• A. two node real application cluster (RAC) system
• B. Autonomous Data Warehouse (ADW) system as it provides auto fail over functionality
• C. two node bare metal system with data guard enabled
• D. single node bare metal system

Correct answer: A

Explanation

The correct answer is A because a two node real application cluster (RAC) system allows for testing high availability and failover scenarios while minimizing costs since it can be run with fewer resources in development. Options B and C involve additional complexity and costs that are not necessary during the application development phase, while option D does not provide the failover capabilities needed for testing hardware failures.
