Oracle Cloud Infrastructure 2019 Developer Associate — Question 159

Which two statements are true about data guard service on DB Systems in Oracle Cloud Infrastructure (OCI)? (Choose two.)

Answer options

• A. Data guard implementation requires two DB Systems, one running the primary database on a virtual machine and the standby database running on bare metal
• B. Data guard configuration on the OCI is limited to one standby database per primary database
• C. Data guard configuration on the OCI is limited to a virtual machine only
• D. Data guard implementation requires two DB Systems, one containing the primary database and one containing the standby database

Correct answer: B, D

Explanation

Option B is correct because the data guard configuration in OCI allows only one standby database for each primary database. Option D is also correct as it accurately states that two DB Systems are needed, one for the primary database and one for the standby. Options A and C are incorrect as they impose unnecessary restrictions that do not align with OCI's capabilities.
