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 C, meaning “Assign Floating IP assignments to Web tier only.”. A Floating IP is the normal mechanism for exposing a workload in an overlay-backed VPC to external clients. It preserves internal VM addressing while publishing a reachable external address through the VPC’s north-south path. In practice, this falls into virtual network design: VPC structure, subnet type, external network behavior, routing intent, and address exposure are what determine the result. 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. 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.

A reliable method here is to translate the scenario into Nutanix terms—VPC routing, external connectivity, policy scope, identity mapping, or upgrade readiness—and then choose the answer that directly addresses that domain. The correct response is B, meaning “Configure a routing policy in the VPC to deny external traffic to and from the database subnet.”. The winning option is the one tied to the native Nutanix object or control that governs the outcome described in the scenario. In practice, this falls into virtual network design: VPC structure, subnet type, external network behavior, routing intent, and address exposure are what determine the result. By contrast, A is not appropriate because NAT changes addressing behavior and does not solve the routing or policy condition described in the scenario. 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. A strong exam habit is to ask which Nutanix construct would have to change for the symptom.

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 D, meaning “Static routes for remote subnets on the VPC”. A VPN showing an “Up” state confirms tunnel establishment, but it does not guarantee end-to-end reachability. Actual traffic flow still depends on route advertisement or static routing, proper prefixes, and correct MTU considerations. MTU planning matters because encapsulation adds overhead. When overlay, Geneve, VXLAN, or IPSec is present, a path that looks healthy at 1500 bytes can still fragment or drop larger frames unless the underlay and endpoints are sized correctly. 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. A strong exam habit is to ask which Nutanix construct would have to change for the symptom or requirement to change. That mental shortcut usually separates the real answer from distractors that mention generic networking steps, disruptive resets, or unrelated configuration objects. Notice that A is not appropriate because NAT changes addressing.
