Which policy mode records traffic without enforcing rule actions?

The clean way to read this scenario is to separate what is merely present in the environment from the single Nutanix construct that actually satisfies the requirement. The correct response is B, meaning “Monitor”. 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.

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. C does not fit because it targets a different layer of the Nutanix networking and security stack than the one causing the outcome here. In practice, administrators who anchor their decisions to Prism Central constructs—such as VPCs, external networks, ERPs, categories, and policy modes—arrive at the correct answer faster and avoid unnecessary changes.
