A company acquires another network using the same IPv4 CIDR as its production VPC. Only a vendor API needs immediate private access; renumbering will take months. What is the best short-term design?

1. Expose the API through PrivateLink instead of joining the overlapping routed networks.
2. Create VPC peering and use more-specific routes for the identical CIDR.
3. Assign the same private IP to both API endpoints and rely on DNS round robin.
4. Propagate both identical CIDRs into the same Transit Gateway route table.
