A remote site's private prefixes are advertised, but only some application regions see them because the VPC uses regional dynamic routing. Which approach best fits?

1. Evaluate Network Connectivity Center with suitable hub and spoke resources.
2. Evaluate Cross-Cloud Interconnect and its supported locations and provider connections.
3. Add the documented redundant connections and attachments for the required availability topology.
4. Review dynamic routing mode and regional applicability of learned routes.
