1Z0-997-25 Question 72
Select 2Your organization has deployed a production Oracle Database on a VM DB System in the Phoenix region. You�ve been asked to set up a disaster recovery environment in the Ashburn region using Data Guard. Which TWO actions are required to properly configure and enable Data Guard for this environment?
- A
Create an empty DB system in the Ashburn region, then configure cross-instance RMAN duplication to establish the standby database.
- B
Use the OCI console to create a standby database from the existing primary DB system, ensuring the database edition supports Data Guard.
- C
Manually copy all Oracle datafiles to an Object Storage bucket in Ashburn, then import them into a new database on the target region.
- D
Confirm that the primary DB System is in an appropriate edition (e.g., Enterprise Edition) that includes Data Guard functionality.
Show answer and explanation
Correct answers: B, D
Explanation
To configure Data Guard for a VM DB System on OCI, you need to ensure your primary database is running a supported edition (Enterprise Edition, Enterprise Edition Extreme Performance, etc.) that includes Data Guard. Then, use the OCI Console to create the standby database, which automatically sets up the DR environment for you. Refer to the Oracle documentation on 'Configuring Data Guard on OCI DB Systems' for the recommended procedure.
- A. Incorrect.
Option 1 is incorrect. You do not need to create an empty DB system and manually replicate data if you are using OCI� built-in Data Guard configuration. The console can automatically create the standby database for you.
- B. Correct.
Option 2 is correct. Using the OCI console to create a standby is the recommended, streamlined approach. You must ensure that the Database Edition supports Data Guard (such as Enterprise Edition).
- C. Incorrect.
Option 3 is incorrect. Manually copying datafiles to Object Storage is not the standard way to establish a Data Guard standby. OCI� integrated Data Guard setup automates the standby creation process without needing a manual datafile copy.
- D. Correct.
Option 4 is correct. Data Guard is only available on certain editions (Enterprise Edition or higher). You must verify that your primary DB system is running a supported edition before configuring Data Guard.
