What type of policy would be used to block all traffic between VMs in the...

From a Nutanix exam perspective, this question is really testing whether the administrator understands the control point that actually governs the behavior shown in the scenario. The correct response is C, meaning “Isolation Policy”. An Isolation Policy is built to stop communication between defined groups. Unlike an application policy, it is intended to create a hard boundary, making it the correct choice when the requirement is “no traffic between these entities.” Quarantine is the fastest containment mechanism in Flow Network Security. It is specifically intended for suspected or compromised workloads that must be isolated immediately without redesigning broader application rules. 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, 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 identity mapping..
