The most professional way to evaluate this question is to map the symptom to the Nutanix feature responsible for that function rather than reacting to secondary details in the prompt. The correct response is C, meaning “Quarantine”. Enforce mode is the stage where Flow stops acting like a discovery tool and starts behaving like a stateful control point. Traffic allowed by the policy continues normally, while traffic that does not match an allowed rule is denied according to policy logic. 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. Seen from a design perspective, the correct answer is the least ambiguous and most supportable implementation path inside Prism Central and AHV. Notice that A does not fit because it targets a different layer of the Nutanix networking and security stack than the one causing the outcome here. B does not fit because it targets a different layer of the Nutanix networking and security stack than the one causing the outcome here. For exam preparation, remember that Nutanix usually separates discovery from enforcement, routing from NAT, and access policy from.
