A Cloud Router is designed to facilitate dynamic routing using Google's Cloud Network infrastructure. The correct interface type that can connect to a Cloud Router using dynamic routing is the Classic VPN tunnel. This type of connection utilizes Border Gateway Protocol (BGP) to support dynamic routing between the Virtual Private Cloud (VPC) network in Google Cloud and an on-premises network or another cloud network.

Dynamic routing offers several advantages over static routing, including the automated exchange of routing information. In the case of a Classic VPN tunnel, when the network topology changes, the routes are automatically updated without requiring manual intervention, which enhances network resilience and flexibility.

When considering the other interface types, a static route does not support dynamic routing as it requires manual configuration of routes, which does not adjust automatically to changes in the network. Direct peering and Private interconnect can also utilize dynamic routing with BGP, but when it specifically comes to the traditional connectivity methods like VPN using a Cloud Router, the Classic VPN tunnel is the prominent interface recognized for dynamic routing within Google Cloud's service offerings.
