Zorluk: ZorConfiguring Network Topology and VPC Infrastructure

A financial enterprise is expanding its cloud presence by establishing private, low-latency network connectivity between its on-premises data center and resources deployed across two Google Cloud regions (`us-east4` and `europe-west3`) within a single Custom Mode Virtual Private Cloud (VPC) network. The on-premises connection requires a guaranteed bandwidth of 10 Gbps, and resources in both regions must dynamically exchange routes with on-premises routers without creating separate regional peering loops. Which TWO architectural actions should be implemented to fulfill these requirements?

  1. Configure the VPC network dynamic routing mode to Global so Cloud Routers can advertise and receive dynamic routes across all regions.Cevap
  2. Provision Dedicated Interconnect circuits between the on-premises facility and Google Cloud colocation facilities.Cevap
  3. C
    Deploy an HA VPN gateway with multiple IPsec tunnels over the public internet to deliver the required 10 Gbps bandwidth and latency SLA.
  4. D
    Establish VPC Network Peering between regional subnets and rely on transit routing through a central spoke to connect regions to on-premises.
  5. E
    Deploy GKE clusters in private mode without setting control plane authorized networks, relying entirely on default firewall rules to block public master endpoints.

Cevap

To meet high-bandwidth requirements and multi-region dynamic routing, configure Global Dynamic Routing on the VPC network and provision Dedicated Interconnect circuits.
Configuring Global Dynamic Routing on the VPC allows BGP dynamic routes learned by a Cloud Router in one region to be distributed to resources in all other regions automatically. Pairing this with Dedicated Interconnect satisfies the strict 10 Gbps bandwidth and low-latency SLA requirements for hybrid connectivity.

Adım Adım Çözüm

1
Determine the physical connectivity option for high throughput (10 Gbps).
Dedicated Interconnect is required because HA VPN tunnels over the public internet cannot guarantee 10 Gbps sustained throughput or strict latency SLAs.
Dedicated Interconnect provides dedicated 10 Gbps or 100 Gbps ports directly connected to Google's edge network.
2
Select the appropriate routing mode for multi-region inter-VPC dynamic route exchange.
Set VPC Dynamic Routing to Global mode.
Regional dynamic routing mode limits Cloud Router dynamic route advertising and learning to the local region. Global dynamic routing allows Cloud Routers in `us-east4` and `europe-west3` to advertise and learn routes across all regions.
