- A
Use the Standard tier with replication and take regular snapshots to Cloud Storage using a scheduled script.
Standard tier provides replication; snapshots to Cloud Storage provide persistency.
- B
Migrate to Cloud SQL for MySQL and use its backup feature.
Why wrong: Not a cache solution.
- C
Enable AOF persistence in Memorystore.
Why wrong: Memorystore does not support persistence.
- D
Increase the maxmemory setting and rely on the allkeys-lru eviction policy.
Why wrong: Eviction does not provide persistence.

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 Memorystore for Redis instance needs to ensure data is not lost during a maintenance event. The team decides to enable persistence. However, Memorystore does not support Redis persistence. What is the recommended alternative?
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
✓
Use the Standard tier with replication and take regular snapshots to Cloud Storage using a scheduled script.
Cloud Memorystore for Redis does not support native Redis persistence (RDB or AOF). To prevent data loss during maintenance events, the recommended alternative is to use the Standard tier (which provides replication and automatic failover) and supplement it with scheduled snapshots exported to Cloud Storage. This approach ensures a durable backup outside the Redis instance that can be restored if needed.
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 misconception that Memorystore supports all native Redis features, including persistence commands like BGSAVE or CONFIG SET appendonly yes, when in fact these are explicitly disabled in the managed service.
Detailed technical explanation
How to think about this question
Cloud Memorystore for Redis uses a fork of Redis that omits the BGSAVE and AOF rewrite commands to simplify management. The Standard tier provides a replica that can take over during maintenance, but both primary and replica are ephemeral; scheduled snapshots to Cloud Storage (using a script that calls SAVE on a replica or uses the EXPORTOPTIONS API) create point-in-time RDB files that can be imported into a new instance. In a real-world scenario, if a zone-level outage occurs and both nodes are lost, only the Cloud Storage snapshot can recover the 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 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.
