Vpc Hybrid Cloud Interconnect Global Dynamic Routing

Worked example. The correct answer is already marked and every option is explained below, so there is nothing to select here. To answer questions yourself, start the free trial.

An enterprise is designing a hybrid network architecture to ingest high-throughput batch and streaming data from an on-premises data center into analytics workloads deployed across subnets in multiple Google Cloud regions (us-central1 and us-east4). The organization requires a secure, private, and highly resilient connection that does not traverse the public internet, while minimizing operational complexity.

The network design must ensure that on-premises data sources can reach processing backends in all VPC subnets across both regions through dynamic routing without deploying separate physical connections in every region.

Which network architecture and configuration should the team implement?

Configure custom static routes on the VPC pointing directly to the Cloud Interconnect physical ports as next hops, and disable Cloud Router BGP sessions.

Deploy dedicated physical Cloud Interconnect connections and Cloud Routers in each subnet, and configure the dynamic routing mode to local.

Set the VPC network dynamic routing mode to regional, deploy a single Cloud Router in us-central1, and rely on default dynamic route propagation to advertise subnets located in us-east4.

Set the VPC network dynamic routing mode to global, deploy Cloud Routers and VLAN attachments in the region associated with the Interconnect colocation facility, and establish BGP sessions to advertise all regional subnets.
