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 A, meaning “The system applies the principle of "most privilege," granting the highest level of access from any assigned role.”. The winning option is the one tied to the native Nutanix object or control that governs the outcome described in the scenario. Operationally, Flow Virtual Networking should be checked from the control plane outward: gateway health, peering state, route advertisement, ERP coverage, external path, and MTU when encapsulation is involved.

Notice that 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. Seen operationally, the correct response is the least disruptive and most deterministic one. It changes the exact Nutanix setting that governs the outcome instead of introducing workarounds elsewhere in the stack.
