Your company recently migrated to Google Cloud in a single region. You configured separate Virtual Private Cloud (VPC) networks for two departments: Department A and Department B. Department A has requested access to resources that are part of Department B’s VPC. You need to configure the traffic from private IP addresses to flow between the VPCs using multi-NIC virtual machines (VMs) to meet security requirements. Your configuration also must:
• Support both TCP and UDP protocols
• Provide fully automated failover
• Include health-checks
• Require minimal manual intervention in the client VMs
Which approach should you take?
A. Create the VMs in the same zone, and configure static routes with IP addresses as next hops.
B. Create the VMs in different zones, and configure static routes with instance names as next hops.
C. Create an instance template and a managed instance group. Configure a single internal load balancer, and define a custom static route with the internal TCP/UDP load balancer as the next hop.
D. Create an instance template and a managed instance group. Configure two separate internal TCP/UDP load balancers for each protocol (TCP/UDP), and configure the client VMs to use the internal load balancers’ virtual IP addresses.
Answer
C
