Exhibit:
A VM with IP address 172.20.9.5 resides on a subnet with CIDR 172.20.9.0/24. The VPC is successfully peered via BGP with an external router... External networks outside the VPC are unable to reach the VM.
What configuration change should be made to enable reachability for the VM?

Suggested Answer: A Vote an answer
This item is best solved by thinking like an operator in Prism Central: first identify whether the problem is design, control-plane state, or policy logic, then pick the option tied to that layer. The correct response is A, meaning "Modify the ERP values within the VPC to advertise a CIDR of 172.20.8.0/22". 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.
Externally Routable Prefixes determine which overlay prefixes are advertised beyond the VPC. If the ERP does not cover the workload subnet, upstream devices never learn a valid return path, even when the local VPC appears healthy. 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 is not appropriate because NAT changes addressing behavior and does not solve the routing or policy condition described in the scenario. C is not appropriate because NAT changes addressing behavior and does not solve the routing or policy condition described in the.
