Difficulty: MediumConfiguring Hybrid Connectivity and VPN Interconnects

A biomedical research enterprise needs to migrate genomic sequence datasets from its primary on-premises facility to a Google Cloud Virtual Private Cloud (VPC). The workload requires a sustained private bandwidth of 15 Gbps. The enterprise facility is not located in a Google Cloud colocation site, but a supported service provider is available nearby. Which TWO actions must the network architect perform to configure this hybrid connection in accordance with Google Cloud best practices?

  1. Provision Partner Interconnect VLAN attachments through the supported service provider to establish connection to the Google Cloud VPC.Answer
  2. B
    Deploy an HA Cloud VPN gateway with four active IPsec tunnels operating over the public internet.
  3. Configure Cloud Routers in the Google Cloud VPC to establish dynamic BGP sessions with the service provider routers.Answer
  4. D
    Establish a VPC Network Peering connection directly between the on-premises router interface and the GCP VPC network.
  5. E
    Configure VPC Service Controls perimeter bridges to encapsulate and route physical layer traffic directly into target Cloud Storage buckets.

Answer

The network architect must provision Partner Interconnect VLAN attachments through a supported service provider and configure Cloud Routers in the VPC network to establish dynamic BGP sessions.
Partner Interconnect is the required solution when high bandwidth (>10 Gbps) is needed and the customer facility is not located in a Google Cloud direct colocation site. Configuring Cloud Routers in the target VPC allows BGP sessions to exchange dynamic routes across the Partner Interconnect VLAN attachments.

Step-by-Step Solution

1
Assess hybrid connectivity bandwidth and location requirements.
Since 15 Gbps bandwidth is required and the company is not in a Google colocation facility, Partner Interconnect is the appropriate choice over Dedicated Interconnect or HA VPN.
Dedicated Interconnect requires colocation at a Google edge location, while Cloud VPN cannot meet 15 Gbps throughput requirements.
2
Provision VLAN attachments with the service provider.
Connects the on-premises router infrastructure to the Google Cloud VPC network via the service provider's network.
Partner Interconnect uses VLAN attachments to bridge the customer premise through the provider to GCP.
3
Configure Cloud Router for dynamic routing.
BGP sessions are configured on the Cloud Router to dynamically announce and learn routes between the VPC and on-premises environment.
Dynamic BGP routing via Cloud Router is mandatory for Cloud Interconnect connections.
