What types of routes exist in a Google Cloud VPC?

In a Google Cloud VPC, routing is crucial for determining how traffic is directed within the network. The main types of routes recognized are static routes, dynamic routes, and default routes.

Static routes are manually configured by network administrators to direct traffic between specific networks or endpoints, providing control over the path that data takes. Dynamic routes, on the other hand, are learned via routing protocols (like BGP) and allow for automatic route adjustments as network topology changes occur. This adaptability is vital in cloud environments where services and connections frequently change. Lastly, default routes serve as a catch-all for any traffic that doesn't match existing route entries, guiding it to a predefined next hop — typically for internet-bound traffic.

The other choices mention routes that either do not exist or use incorrect terminology for Google Cloud networking components, such as VPN routes and Peer routes. Understanding the difference between the recognized types ensures that network engineers can effectively design and manage their VPC configurations.
