- A
Switch from HDD to SSD storage.
Why wrong: Memorystore uses memory, not disk storage types.
- B
Enable Redis Cluster to shard data across multiple nodes.
Redis Cluster allows horizontal scaling.
- C
Add a cross-region replica to increase read capacity.
Why wrong: Cross-region replicas are not supported; replicas are within same region.
- D
Increase the maxmemory setting beyond the tier limit.
Why wrong: maxmemory cannot exceed the tier's memory allocation.
- E
Upgrade to a larger tier (e.g., from M5 to M10).
Vertical scaling increases capacity.

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 runs Memorystore for Redis with a Standard tier instance. They want to scale to higher throughput and memory capacity beyond the current tier limits. Which TWO actions should they take?
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 Redis Cluster to shard data across multiple nodes.
Redis Cluster shards data across multiple nodes, allowing horizontal scaling beyond the limits of a single Standard tier instance. This enables higher throughput and memory capacity by distributing the dataset across multiple primary nodes, each handling a subset of the keyspace.
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
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Switch from HDD to SSD storage.
Why it's wrong here
Memorystore uses memory, not disk storage types.
- ✓
Enable Redis Cluster to shard data across multiple nodes.
Why this is correct
Redis Cluster allows horizontal scaling.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between vertical scaling (upgrading tier) and horizontal scaling (sharding), and candidates may mistakenly think that increasing maxmemory or adding replicas can overcome tier limits, when in fact replicas do not increase total memory capacity and maxmemory is bounded by the instance's physical RAM.
Detailed technical explanation
How to think about this question
Redis Cluster uses a hash slot mechanism (16,384 slots) to distribute keys across nodes, with each node responsible for a subset of slots. When scaling, you can add nodes and reshard slots using the CLUSTER ADDSLOTS command or automated tools like redis-cli --cluster rebalance. In Memorystore, enabling Redis Cluster automatically partitions data and provides built-in failover for high availability, but requires client-side support for cluster mode (e.g., Redis Cluster client libraries).
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.
