Exam 2V0-15.25 Topic 3 Question 13 Discussion

In VMware Cloud Foundation 9.0, usingvSAN Express Storage Architecture (ESA)withAuto-Policy Management, the system automatically selects the correct storage policy based on the cluster size and desired failure protection. When the administrator configures tolerance for a single failure (FTT=1 using RAID-1 mirroring), vSAN ESA requiressufficient remaining hosts during a failure eventto reprotect objects.
Aminimum of 3 ESA-capable hostsis required for RAID-1, and re-protection after a failure requires enough hosts with available capacity to place new replica components. In small ESA clusters (e.g., 3 or 4 nodes), if one host fails, the remaining hosts may not meet the placement rules for automatic rebuild to restore compliance. ESA enforces strict placement rules to maintain consistent performance and resilience; if vSAN determines that object layout compliance cannot be restored without violating these rules, it entersReduced availability with no rebuildstate.
This behavior is expected and documented: rebuilds cannot occur if the cluster does not have sufficient hosts or free capacity to recreate absent components. The administrator's ESA configuration behaved correctly given the cluster size limitation, makingBthe correct answer.
