- A
Take periodic snapshots and store them in Cloud Storage
Snapshots to GCS are the recommended method for persistence.
- B
Enable AOF persistence in Memorystore settings
Why wrong: Memorystore does not support AOF or RDB persistence.
- C
Use a standard tier instance with persistence enabled
Why wrong: Standard tier offers replication but not persistence.
- D
Enable auto-backup in Memorystore
Why wrong: Memorystore does not have auto-backup.

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 is using Memorystore for Redis and needs to persist data across restarts. Which option should they use?
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
✓
Take periodic snapshots and store them in Cloud Storage
Memorystore for Redis does not natively support AOF persistence; it relies on periodic RDB snapshots to persist data. By taking these snapshots and storing them in Cloud Storage, you can restore the Redis instance after a restart or failure, ensuring data durability across restarts.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Enable AOF persistence in Memorystore settings
Why it's wrong here
Memorystore does not support AOF or RDB persistence.
- ✗

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the misconception that Memorystore supports AOF persistence like self-managed Redis, but in reality, it only supports RDB snapshots for data persistence.
Detailed technical explanation
How to think about this question
Memorystore for Redis uses RDB (Redis Database) snapshots, which are point-in-time binary dumps of the dataset. These snapshots are stored in Cloud Storage and can be used to restore the instance. Under the hood, the snapshot frequency is configurable (e.g., every 1 hour or after 1,000 writes), and the restore process involves loading the RDB file into a new or existing instance. A real-world scenario is when an instance crashes due to a zone outage; the snapshot in Cloud Storage allows you to spin up a new instance with minimal data loss.
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.
