1Z0-1072-25 Question 187
Single answerYou are operating a production OLTP application on an OCI compute instance that has a Block Volume attached. The business requires near real-time data protection with minimal recovery point objective (RPO) to handle any unexpected data corruption or accidental loss. Which solution best addresses these requirements in Oracle Cloud Infrastructure?
- A
Schedule full block volume backups once every 24 hours
- B
Take manual on-demand block volume backups during maintenance windows
- C
Use Block Volume Replication to asynchronously replicate data to a target volume in another region or availability domain
- D
Create a cloned volume every time the application writes data to the original volume
Show answer and explanation
Correct answer: C
Explanation
Block Volume Replication is designed for asynchronous, near real-time replication of block volumes to another region or availability domain, helping organizations minimize data loss in the event of failures. Unlike manual or scheduled backups, which can leave considerable data gaps, replication continuously updates the target volume as changes occur. Refer to the official Oracle Cloud Infrastructure Block Volume Replication documentation for detailed setup instructions and best practices: https://docs.oracle.com/en-us/iaas/Content/Block/Concepts/blockvolumereplication.htm
- A. Incorrect.
Option 1: Incorrect. Scheduling full backups once every 24 hours does not protect data in near real-time. The RPO in this approach would be the time between backups, which could be up to 24 hours.
- B. Incorrect.
Option 2: Incorrect. Manually taking on-demand backups only during maintenance windows leaves gaps in coverage and does not meet near real-time data protection requirements. Operators may forget or not have time to perform backups regularly.
- C. Correct.
Option 3: Correct. Block Volume Replication allows you to asynchronously replicate a Block Volume to another region or a different availability domain. It provides near real-time replication and ensures that you have an up-to-date copy of your data to reduce RPO significantly.
- D. Incorrect.
Option 4: Incorrect. Though cloning a volume is relatively fast, it is typically done as needed rather than continually. Creating clones each time data changes would be cumbersome and not practical for near real-time protection.
