1Z0-1067-25 Question 71
Single answerYou manage a mission-critical e-commerce platform hosted in a single region on Oracle Cloud Infrastructure (OCI). The business requires a maximum Recovery Time Objective (RTO) of two hours and a Recovery Point Objective (RPO) of 30 minutes for the database in the event of a regional outage. You must also keep operational costs at a reasonable level. Which disaster recovery strategy best meets these requirements?
- A
Use Oracle Data Guard in synchronous mode to replicate from the primary region to a standby database in a second region, ensuring zero data loss.
- B
Schedule full backups every six hours to Object Storage in the same region and rely on restore operations if the region fails.
- C
Use Oracle Data Guard in asynchronous mode to replicate from the primary region to a standby database in a second region, with monthly failover testing.
- D
Perform weekly manual exports of the database to Object Storage in another region, and restore the environment if the primary region fails.
Show answer and explanation
Correct answer: C
Explanation
Oracle Data Guard is a recommended solution for disaster recovery scenarios on OCI. Asynchronous replication trades off a negligible data loss window for lower performance overhead and cost, aligning well with typical RTO/RPO requirements in many enterprise environments. Monthly failover drills help ensure reliable recovery procedures. Refer to the Oracle Data Guard documentation on the OCI console for best practices in setting up and testing standby environments.
- A. Incorrect.
Option 1: While synchronous replication can ensure zero data loss, it typically increases latency and operational costs. It may exceed the organization� performance requirements without providing a proportional benefit for this RPO/RTO scenario.
- B. Incorrect.
Option 2: Backing up every six hours to the same region does not meet the 30-minute RPO requirement and does not protect against a complete regional outage. Restoring from these backups could exceed the two-hour RTO.
- C. Correct.
Option 3: Using Oracle Data Guard in asynchronous mode to replicate to another region helps maintain near real-time copies of the database at a lower performance overhead than synchronous mode. Monthly failover testing validates the failover process, improving confidence in meeting both the two-hour RTO and 30-minute RPO while keeping costs manageable.
- D. Incorrect.
Option 4: Weekly manual exports provide only a coarse level of protection. Restoring from weekly exports would risk significant data loss, failing the 30-minute RPO requirement, and the manual process could easily exceed the two-hour RTO.
