Oracle Cloud Infrastructure 2019 Developer Associate — Question 126

What is true about data guard set up with fast-start failover (FSFO) in Oracle Cloud Infrastructure (OCI)?

Answer options

• A. The best practice for high availability and durability is to run the primary, standby, and observer in separate availability domains (ADs).
• B. When you configure data guard using OCI console, the default mode is set to maxprotection.
• C. You cannot create the standby DB system in a different AD from the primary DB system.
• D. You cannot use database command line interface (CLI) to set up data guard with FSFO.

Correct answer: A

Explanation

Option A is correct because running the primary, standby, and observer in separate availability domains enhances high availability and durability. Option B is incorrect as the default mode for data guard setup is not maxprotection but rather maxavailability. Option C is false because it is possible to create a standby DB system in a different AD. Option D is also incorrect since the CLI can be used to set up data guard with FSFO.
