You are responsible for designing a new connectivity solution between your organization's on-premises data center and your Google Cloud Virtual Private Cloud (VPC) network.

  • A. Use one Dedicated Interconnect connection in a single metropolitan area. Configure one Cloud Router and enable global routing in the VPC.
  • B. Use a Direct Peering connection between your on-premises data center and Google Cloud. Configure Classic VPN with two tunnels and one Cloud Router.
  • C. Use two Dedicated Interconnect connections in a single metropolitan area. Configure one Cloud Router and enable global routing in the VPC.
  • D. Use HA VPN. Configure one tunnel from each interface of the VPN gateway to connect to the corresponding interfaces on the peer gateway on-premises. Configure one Cloud Router and enable global routing in the VPC.

For Dedicated Interconnects: At least four Dedicated Interconnect connections, two connections in one metropolitan area (metro) and two connections in another metro. Connections that are in the same metro must be placed in different edge availability domains (metro availability zones) to achieve 99.99% availability. For HA VPN: HA VPN to peer VPN gateways Connect an HA VPN gateway to one or two separate peer VPN devices 99.99% HA VPN between two Google Cloud networks Connect two Google Cloud VPC networks in a single region by using an HA VPN gateway in each network 99.99%

"The following resources and settings are required to achieve 99.99% availability: At least four Dedicated Interconnect connections, two connections in one metropolitan area (metro) and two connections in another metro. Connections that are in the same metro must be placed in different edge availability domains (metro availability zones) to achieve 99.99% availability. Placing Dedicated Interconnect connections in two separate edge availability domains within the same metro is important because maintenance windows are coordinated across edge availability domains within a metro, while maintenance windows are not coordinated across metros." https://cloud.google.com/network-connectivity/docs/interconnect/tutorials/dedicated-creating-9999-availability Due to this, I change answer to D
