Difficulty: MediumConfiguring Hybrid Connectivity and VPN Interconnects

A university research institute needs to establish hybrid network connectivity between its primary on-premises facility and a Google Cloud Virtual Private Cloud (VPC) network. The institute is not located in a Google Cloud Interconnect colocation facility and requires a private network connection providing 4 Gbps of bandwidth that does not traverse the public internet. Additionally, the hybrid connectivity architecture must strictly satisfy Google Cloud's 99.99% availability SLA. Which network deployment strategy should the Cloud Architect implement to meet these requirements?

  1. Provision a Partner Interconnect connection with redundant VLAN attachments deployed across two distinct service provider edge availability domains, using Cloud Router to establish dynamic BGP routing.Answer
  2. B
    Provision a single 10 Gbps Dedicated Interconnect circuit connected directly to a Cloud Router within the target GCP region.
  3. C
    Provision an HA Cloud VPN gateway with two active IPsec tunnels configured with Cloud Router for dynamic routing over public internet links.
  4. D
    Configure VPC Network Peering directly between the on-premises edge router and the Google Cloud VPC network.

Answer

Provisioning a Partner Interconnect connection with redundant VLAN attachments across two distinct edge availability domains, routed dynamically using Cloud Router, fulfills all requirements for private non-internet bandwidth, missing colocation presence, and 99.99% SLA availability.
The correct choice utilizes Partner Interconnect, which is explicitly designed for enterprise hybrid connections when the on-premises facility is not co-located at a Google Cloud Interconnect location. By ordering capacities from a supported service provider, selecting a total bandwidth of 4 Gbps, and deploying redundant VLAN attachments in two separate Edge Availability Domains with Cloud Router, the organization achieves private network isolation and satisfies Google Cloud's 99.99% SLA guidelines.

Step-by-Step Solution

1
Analyze facility constraints and connectivity medium requirements.
Since the institute is not co-located at a Google Cloud peering facility and cannot use the public internet, Dedicated Interconnect and HA Cloud VPN are ruled out.
Dedicated Interconnect requires a co-location presence in a Google facility, whereas HA Cloud VPN operates over public internet circuits.
2
Evaluate throughput and SLA topology requirements.
A 4 Gbps requirement exceeds standard VPN limits and demands Partner Interconnect. To achieve a 99.99% SLA, redundant VLAN attachments must be provisioned across two edge availability domains (EADs) with Cloud Router dynamic BGP routing.
Google Cloud's 99.99% SLA for Partner Interconnect specifically requires dual VLAN attachments across two distinct EADs connected to dual Cloud Routers.

Key Concept

Selecting and configuring Google Cloud Partner Interconnect for 99.99% HA topology without direct facility co-location.
