Exam NCP-NS-7.5 Topic 1 Question 31 Discussion

This item is best solved by thinking like an operator in Prism Central: first identify whether the problem is design, control-plane state, or policy logic, then pick the option tied to that layer. The correct response is A, meaning "ICMP is not allowed between the Web and App categories.". The winning option is the one tied to the native Nutanix object or control that governs the outcome described in the scenario. This is a Flow policy design question, so categories, secured entities, rule direction, policy mode, and policy precedence matter more than simple IP connectivity assumptions. By contrast, B does not fit because it targets a different layer of the Nutanix networking and security stack than the one causing the outcome here. C does not fit because it targets a different layer of the Nutanix networking and security stack than the one causing the outcome here.
That is the underlying Nutanix principle being validated: solve the issue at the feature that owns the behavior, not by changing unrelated infrastructure settings that happen to sound network-oriented. A strong exam habit is to ask which Nutanix construct would have to change for the symptom or requirement to.
