- A
Enable automated backups with a suitable retention period.
Backups are essential for recovery.
- B
Create a read replica in the same region.
Why wrong: Does not survive a regional outage.
- C
Increase the storage size to accommodate future growth.
Why wrong: Not a DR measure.
- D
Create a cross-region read replica and configure it for failover.
Cross-region replica provides DR and can be promoted.
- E
Enable binary logging (log_bin) for point-in-time recovery.
PITR reduces data loss.

PCDOE Manage Database Solutions Practice Question
This PCDOE practice question tests your understanding of manage database solutions. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A Cloud SQL for MySQL instance is being used for a production application. The team wants to implement a disaster recovery plan that can recover from a regional outage with minimal data loss and automatic failover. Which three steps should they take? (Choose THREE.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable automated backups with a suitable retention period.
Option A is correct because automated backups in Cloud SQL for MySQL provide a baseline for disaster recovery by creating daily backups that can be restored to a new instance. With a suitable retention period, you can recover from data corruption or accidental deletion, though backups alone do not provide automatic failover or minimal data loss during a regional outage.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse read replicas in the same region as providing disaster recovery for regional outages, but they only offer read scaling and high availability within the same region, not cross-region failover.
Detailed technical explanation
How to think about this question
Cross-region read replicas in Cloud SQL for MySQL use asynchronous replication based on MySQL's binary log (binlog). When configured for failover, you can promote the replica to a standalone primary instance, but due to asynchronous replication, there may be some data loss (typically seconds to minutes) depending on replication lag. Enabling binary logging (log_bin) is essential for point-in-time recovery (PITR), allowing you to restore to any specific timestamp within the backup retention period, which is critical for minimizing data loss beyond the last automated backup.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
