Refer to the exhibit. Based on the exhibit what can be definitively determined about Host DEMO- AHV-2?
The correct answer is A. it has performed more on-disk lookups than the other nodes. In Nutanix's storage architecture, the Unified Cache tracks cache hits (data served from SSD/memory) versus cache misses, which result in on-disk lookups against spinning HDD storage. An exhibit showing elevated cache miss or on-disk read metrics for DEMO-AHV-2 compared to…

Explanation
In Nutanix's storage architecture, the Unified Cache tracks cache hits (data served from SSD/memory) versus cache misses, which result in on-disk lookups against spinning HDD storage. An exhibit showing elevated cache miss or on-disk read metrics for DEMO-AHV-2 compared to other nodes definitively indicates it has performed more on-disk lookups. This is an observable, measurable statistic. The other choices-undersized cache, undersized system memory, or hosting more VMs-cannot be definitively concluded from disk lookup statistics alone without additional comparative baselines or thresholds.
