A financial transaction processing company is connecting its on-premises core infrastructure to a Google Cloud Virtual Private Cloud (VPC) network. The architecture requires a high-bandwidth connection capable of supporting a 99.99% Availability Service Level Agreement (SLA) for Dedicated Interconnect, operating entirely over private infrastructure without traversing the public internet. Which TWO deployment steps are required to meet the 99.99% SLA availability requirements?
- Provision at least four Dedicated Interconnect connections across two distinct metropolitan areas (metros) and two Edge Availability Domains per metro.Cevap
- Configure Cloud Routers in two distinct Google Cloud regions and enable Global Dynamic Routing on the target VPC network.Cevap
- CDeploy a pair of High Availability (HA) Cloud VPN gateways operating over public IP addresses to serve as the secondary failover path.
- DEstablish VPC Network Peering directly between the on-premises edge routers and the Google Cloud VPC network.
- EConfigure VPC Service Controls perimeters to function as the primary layer 3 routing mechanism for hybrid traffic transit.
Cevap
To achieve a 99.99% availability SLA for Dedicated Interconnect, you must provision four connections total across two distinct metropolitan areas (using two Edge Availability Domains per metro) and deploy Cloud Routers in two distinct GCP regions with Global Dynamic Routing enabled on the VPC.
Achieving a 99.99% SLA for Dedicated Interconnect requires physical and logical redundancy across multiple facilities and regions. Specifically, you must order four Dedicated Interconnect connections divided across two distinct metros and two Edge Availability Domains per metro. At the network level, Cloud Routers must be deployed in two separate GCP regions inside the VPC, and Global Dynamic Routing must be enabled so that BGP routes are advertised and managed globally across the VPC.
