Zorluk: ZorConfiguring Hybrid Connectivity and VPN Interconnects

A healthcare organization is migrating its electronic health record (EHR) system to Google Cloud. The architecture team requires a hybrid network solution connecting their on-premises data centers to a Virtual Private Cloud (VPC) network. To support continuous data replication, the architecture must deliver at least 20 Gbps of bandwidth and satisfy Google Cloud's 99.99% uptime Service Level Agreement (SLA) for Dedicated Interconnect. Which two architectural configurations must be implemented to achieve this SLA requirement? (Select TWO.)

  1. Provision at least four Dedicated Interconnect connections distributed across two distinct edge availability domains (metropolitan areas).Cevap
  2. Configure redundant Cloud Routers in the VPC network and attach VLAN attachments from separate edge locations to different Cloud Routers.Cevap
  3. C
    Set up VPC Network Peering between the hybrid VPC network and secondary workload VPC networks to enable transitive routing across on-premises environments.
  4. D
    Deploy a single pair of HA Cloud VPN tunnels over the public internet as the primary high-throughput transit method for the 20 Gbps workload.
  5. E
    Configure VPC Service Controls perimeters directly on the Cloud Routers to enforce IPsec data encryption across the physical Interconnect circuits.

Cevap

To meet Google Cloud's 99.99% availability SLA for Dedicated Interconnect, the architecture requires provisioning four Dedicated Interconnect connections across two edge availability domains (metropolitan areas) and configuring redundant Cloud Routers with VLAN attachments distributed across them.
Google Cloud defines explicit architecture requirements to achieve a 99.99% SLA for Dedicated Interconnect: organizations must deploy four Dedicated Interconnect connections distributed across two edge availability domains (metropolitan areas) and configure redundant Cloud Routers in the VPC network with VLAN attachments connecting to each edge domain.

Adım Adım Çözüm

1
Analyze high-availability topology requirements for GCP Dedicated Interconnect 99.99% SLA.
GCP topology rules specify that 99.99% availability requires 4 Dedicated Interconnect connections split evenly across 2 distinct edge availability domains.
Redundancy across multiple edge facilities protects against metro-level or facility-level hardware outages.
2
Determine Cloud Router and control plane redundancy requirements.
Two Cloud Routers must be deployed in the VPC network, each hosting VLAN attachments linked to different edge availability domains.
This guarantees that BGP dynamic routing sessions remain active even if one Cloud Router or edge location fails.
3
Evaluate bandwidth and network service boundaries.
Dedicated Interconnect provides 10 Gbps or 100 Gbps physical circuits per connection, easily meeting the 20 Gbps requirement, whereas Cloud VPN is limited to 3 Gbps per tunnel.
HA Cloud VPN cannot handle 20 Gbps throughput as a single primary link.
