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
✓
SSD acts as a write cache and read cache to accelerate I/O.
In HyperFlex, the SSD (or flash) in hybrid nodes serves as a cache for frequently accessed data, while the HDDs provide bulk storage. The HXDP uses SSDs for both caching and persistent storage in all-flash nodes.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
SSD is used only for metadata storage.
Why it's wrong here
SSD is used for caching data, not just metadata.
- ✗
SSD is used for long-term persistent storage, while HDD is used for caching.
Why it's wrong here
In hybrid nodes, HDD is for capacity, SSD for cache.
- ✓
SSD acts as a write cache and read cache to accelerate I/O.
Why this is correct
