- A
Increase the backup retention period to 30 days.
Why wrong: Retention period only affects how long backups are kept, not their geographic redundancy.
- B
Create a cross-region read replica.
A cross-region read replica can be promoted to a standalone instance in the event of a regional outage.
- C
Enable cross-region backup replicas.
Cross-region backup replicas store backups in a different region, ensuring availability during regional outages.
- D
Enable point-in-time recovery with a 7-day retention.
Why wrong: PITR does not provide cross-region protection by itself; it relies on binary logs stored in the same region.
- E
Schedule more frequent on-demand backups.
Why wrong: On-demand backups are stored in the same region unless cross-region location is set.

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 company uses Cloud SQL for MySQL with automated backups enabled. They want to ensure they can recover their database in the event of a regional outage. Which TWO actions should they take? (Choose two.)
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
✓
Create a cross-region read replica.
Option B is correct because a cross-region read replica in Cloud SQL for MySQL provides a standby copy of the database in a different region, which can be promoted to a primary instance during a regional outage, enabling recovery with minimal data loss. Option C is correct because cross-region backup replicas (also known as cross-region backup copies) allow backups to be stored in a separate region, ensuring that backup data survives a regional disaster and can be used to restore the database in another region.
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
Cisco often tests the distinction between high-availability features (like read replicas) and disaster recovery features (like cross-region backups), and the trap here is that candidates confuse point-in-time recovery or increased retention within a single region as sufficient for regional disaster recovery, when they only protect against local failures or accidental data loss.
Detailed technical explanation
How to think about this question
Cross-region read replicas use asynchronous replication based on MySQL's binary log (binlog) to maintain a consistent copy in another region; when promoted, the replica becomes a new primary with its own write endpoint, and the original primary's data may be lost if the outage is catastrophic. Cross-region backup replicas automatically copy automated backups and transaction logs to a user-specified destination region, enabling restore operations from that region even if the source region is completely unavailable.
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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
