- A
Create a cross-region replica for failover
Why wrong: Cross-region replica provides disaster recovery but not PITR capability.
- B
Enable automated backups only
Why wrong: Automated backups provide daily snapshots but not point-in-time granularity.
- C
Configure binary logging and set a PITR retention period
Binary logging is required for PITR, and the retention period determines how far back you can recover.
- D
Set up an on-demand backup every hour
Why wrong: On-demand backups are snapshots at a point in time, but they don't enable PITR to an arbitrary time.

PCDOE Manage Database Solutions Practice Question
This PCDOE practice question tests your understanding of manage database solutions. 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 runs an e-commerce application on Cloud SQL for MySQL. They need to recover the database to a specific point in time 15 minutes ago after an accidental data deletion. What must be configured beforehand?

Correct answer & explanation
✓
Configure binary logging and set a PITR retention period
Point-in-time recovery (PITR) in Cloud SQL for MySQL relies on binary logging (binlog) to capture all write operations. To recover to a specific moment (e.g., 15 minutes ago), you must enable automated backups (which provide the base restore point) and configure binary logging with a retention period that covers the desired recovery window. Option C correctly specifies both requirements: binary logging must be enabled, and a PITR retention period (e.g., 1–7 days) must be set to retain the necessary binlog files for replay.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why it's wrong here
On-demand backups are snapshots at a point in time, but they don't enable PITR to an arbitrary time.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the misconception that automated backups alone are sufficient for point-in-time recovery, but candidates must recognize that binary logging and a PITR retention period are required to replay transactions beyond the last snapshot.
Detailed technical explanation
How to think about this question
Cloud SQL for MySQL uses the mysql-bin.* files (binary logs) to record every data-changing statement. During PITR, the service restores the most recent automated backup before the target time, then replays the binary logs up to the exact timestamp or position. The PITR retention period determines how long these binlogs are kept; if the retention is set to 1 day, you can recover to any point within the last 24 hours. A common subtlety is that binary logging must be enabled before the incident occurs—it cannot be turned on retroactively to recover lost data.
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.
