Oracle Cloud Infrastructure 2023 Multicloud Architect Associate — Question 22

How many DB systems must you provision before you can enable Oracle Data Guard for a virtual machine DB system database?

Answer options

• A. It depends on how many standby databases you want for your primary database in the Oracle Data Guard configuration in Oracle Cloud Infrastructure.
• B. Three, first for the primary database, second for the standby database, and a third for the staging database in the Oracle Data Guard configuration.
• C. Two for both the primary and standby databases, because a DB system with the database that you want to use as the standby must already exist before you enable Oracle Data Guard.
• D. Only one for the primary database, because a new DB system is provisioned for the standby database when it is created and associated with the primary database while enabling Oracle Data Guard.

Correct answer: D

Explanation

The correct answer is D because only one DB system is required for the primary database, and the standby database DB system is automatically provisioned when Oracle Data Guard is enabled. Options A, B, and C suggest unnecessary additional DB systems or misinterpret the provisioning process for Oracle Data Guard.
