Exam NCP-MCI-7.5 Topic 1 Question 30 Discussion

Nutanix documentation for Updating Capacity Configurations explains that the Reserve Capacity For Failure option determines whether runway analysis should account for the impact of a node failure, and when Auto Detect is selected, Prism Central automatically uses the cluster's failure assumptions rather than the full unconstrained cluster total. In practical runway terms, that means the calculation reflects the loss of the node whose failure would have the greatest effect on usable capacity. Among the provided options, the best match for that documented logic is D: the runway analysis excludes the resources of the largest node so estimates account for a node failure. ( Nutanix Portal ) This behavior is important because runway is intended to answer "how long until I run out of safe usable capacity," not just "how long until all raw resources are consumed." Nutanix therefore lets administrators model capacity while preserving headroom for failure scenarios. The fixed 10% answer is too generic and not how Nutanix documents the option. Storage-only reservation also misses the fact that runway tracks CPU, memory, and storage dimensions. So, based on Nutanix's Auto Detect wording and the resilience-oriented design of runway planning, D is the most authentic answer. ( Nutanix Portal )
