- A
Enable automated backups with a retention of 30 days and enable binary logging (write-ahead logs) for point-in-time recovery.
Automated backups provide daily backups; binary logs allow recovery to any point within the retention period.
- B
Manually take a full backup every day and store it in Cloud Storage with object lifecycle management set to 30 days.
Why wrong: Full backups only capture a single point in time.
- C
Take daily snapshots of the Compute Engine instance running Cloud SQL.
Why wrong: Cloud SQL is not on Compute Engine; snapshots not applicable.
- D
Use Cloud Scheduler to run a script that exports the database to Cloud Storage every hour, and keep the exports for 30 days.
Why wrong: This does not provide point-in-time recovery.

Cloud SQL Backup and Point-in-Time Recovery Configuration
This PCSE practice question tests your understanding of pcse exam topics. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 PostgreSQL and needs to ensure that database backups are retained for 30 days for compliance. They also want to be able to perform point-in-time recovery for the last 24 hours. What configuration should they use?
Quick Answer
The correct configuration is to enable automated backups with a 30-day retention and enable binary logging (write-ahead logs) for point-in-time recovery. This works because Cloud SQL’s automated backups provide the full database snapshots needed for long-term retention, while binary logs (WAL in PostgreSQL) capture every transaction, allowing you to replay changes and restore to any specific second within the last 24 hours. On the Google Professional Cloud Security Engineer exam, this question tests your understanding of Cloud SQL’s backup architecture and the distinction between retention policies and recovery granularity. A common trap is confusing manual exports or snapshots with point-in-time recovery—exports are static, and Cloud SQL does not support snapshot-based recovery. Remember the pairing: automated backups handle retention duration, and binary logs handle recovery window. A useful memory tip is “30 days of full, 24 hours of fine”—the full backup covers compliance, the logs cover granular recovery.
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 retention of 30 days and enable binary logging (write-ahead logs) for point-in-time recovery.
Option A is correct because Cloud SQL automated backups and binary log (WAL) archiving enable point-in-time recovery. Option B is incorrect because export to Cloud Storage is a manual process. Option C is incorrect because snapshots are not supported for Cloud SQL. Option D is incorrect because manual backups do not provide point-in-time recovery.
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
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.
