Oracle Cloud Infrastructure 2019 Cloud Operations Associate — Question 21

How do you enable a default connection between Database as a Service (DBaaS) instances?

Answer options

• A. by creating network groups and adding the instances that you want to communicate to that group
• B. by creating dedicated communication keys and setting them to be used only for your DBaaS instance-to-instance communication
• C. by creating nothing for communication between the DBaaS instances because all instances are interconnected by default
• D. by installing and configuring the NETMGR utility for your DBaaS environment, and then using it to set up the required communication channels

Correct answer: B

Explanation

The correct answer is B because creating dedicated communication keys ensures secure and controlled interaction between DBaaS instances. Option A is incorrect as it describes a method that does not apply to DBaaS's default behavior. Option C is misleading because while DBaaS instances might be interconnected, secure communication often requires specific configurations. Option D is not applicable as NETMGR is not a required tool for establishing default connections in DBaaS.
