Difficulty: EasyConfiguring Hybrid Connectivity and VPN Interconnects

An organization plans to establish a Dedicated Interconnect connection between its on-premises network and a Google Cloud Virtual Private Cloud (VPC) network. Which TWO configuration steps are required to set up this hybrid connectivity solution? (Select two.)

  1. Provision physical cross-connects between the on-premises router and Google edge router at a supported colocation facility.Answer
  2. Configure a Cloud Router and create VLAN attachments (interconnect attachments) in the target GCP VPC network.Answer
  3. C
    Establish Classic VPN IPsec tunnels over the public internet to carry the underlying Interconnect traffic.
  4. D
    Configure VPC Network Peering directly between the on-premises router and the Google Cloud VPC network.
  5. E
    Deploy VPC Service Controls perimeters to configure the underlying BGP dynamic routing protocol.

Answer

The two required steps are provisioning physical cross-connects at a supported colocation facility and configuring a Cloud Router with VLAN attachments in the GCP VPC network.
Establishing a Dedicated Interconnect requires physical cross-connects between the on-premises router and Google edge routers at a colocation facility. Additionally, logically connecting the VPC requires establishing VLAN attachments and configuring a Cloud Router to manage BGP sessions for dynamic route exchanges.

Step-by-Step Solution

1
Identify the physical connection requirements for Dedicated Interconnect.
Determine that physical cross-connect cables must be ordered and provisioned at a supported Google colocation facility.
Dedicated Interconnect requires direct physical fiber connectivity to Google edge infrastructure.
2
Identify the logical routing requirements in Google Cloud.
Create a Cloud Router and construct VLAN attachments within the target VPC network.
VLAN attachments allocate private VLANs on the connection, and Cloud Router manages BGP dynamic routing sessions to exchange routes.
