High SSD utilization in a hybrid cluster can lead to increased I/O latency as new writes may spill over to HDDs, reducing overall performance.
Option D (Average I/O latency in the cluster may increase) is correct:
If SSD usage isabove 75%,data tiering shifts to slower HDDs,increasing latency.
Option A is incorrect:
SSD failures are managed via redundancy policies (RF2/RF3), and high utilizationdoes not impact failure handling.
Option B is incorrect:
Metadata is stored separately, and high SSD usage does not mean metadata is at risk.
Option C is incorrect:
Clusters do not go into read-only mode due to high SSD utilization—they simply experienceperformance degradation.
