- A
Standard Tier (replication)
Standard Tier provides a replica in a different zone for automatic failover.
- B
Export functionality to Cloud Storage
Export creates a snapshot that can be stored in Cloud Storage for DR.
- C
Redis Cluster
Why wrong: Redis Cluster provides horizontal scaling, not necessarily automatic failover with backup to Cloud Storage.
- D
AOF persistence
Why wrong: AOF is not supported in Memorystore; it is a Redis feature but not available.
- E
Basic Tier
Why wrong: Basic Tier is a single node without replicas, so no automatic failover.

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 Memorystore for Redis and wants to achieve high availability with automatic failover. They also need to periodically back up the data to Cloud Storage for disaster recovery. Which TWO features should they use? (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
✓
Standard Tier (replication)
Standard Tier (replication) provides a primary-replica architecture with automatic failover, ensuring high availability. The Export functionality allows you to manually or scheduled export Redis data to Cloud Storage, enabling point-in-time recovery for disaster recovery purposes.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown

Why it's wrong here
Basic Tier is a single node without replicas, so no automatic failover.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The Google Cloud exam often tests the distinction between high-availability features (replication/failover) and durability/backup features (export to Cloud Storage), tricking candidates into selecting AOF persistence or Redis Cluster as solutions for disaster recovery.
Detailed technical explanation
How to think about this question
Standard Tier uses synchronous replication to the replica and automatic failover via Sentinel or the managed service's health-check mechanism, typically with a 5-second failover window. The Export feature creates an RDB snapshot that is uploaded to a Cloud Storage bucket, which can be used to restore the Redis instance in a different region or project, supporting RPOs of minutes to hours depending on export frequency.
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.
