350-601 Compute Practice Question
An organization is deploying a HyperFlex cluster for a database workload requiring low latency and high IOPS. Which node type should be selected?
⚠ Common exam trap
Cisco often tests the misconception that hybrid nodes are sufficient for 'high performance' workloads, but the specific requirement for 'low latency and high IOPS' explicitly demands all-flash nodes to avoid HDD bottlenecks.
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
✓
All-flash nodes
All-flash nodes use only SSDs for both caching and persistent storage, delivering the lowest latency and highest IOPS required for demanding database workloads. In a HyperFlex cluster, all-flash configurations eliminate the rotational latency of HDDs, ensuring consistent sub-millisecond response times critical for OLTP databases.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Hybrid HDD/SSD nodes
Why it's wrong here
Hybrid nodes combine HDD and SSD; suitable for general workloads but not optimal for highest IOPS.
- ✓
All-flash nodes
Why this is correct
All-flash nodes deliver the best performance for high IOPS and low latency.
- ✗
Compute-only nodes
Why it's wrong here
Compute-only nodes have no local storage; they rely on remote storage, which may increase latency.
- ✗
Witness VM nodes
Why it's wrong here
Witness VMs are for cluster quorum, not for data storage.
