Actual exam question from Google's Professional Cloud Network Engineer
Question #: 101
Topic #: 1
[All Professional Cloud Network Engineer Questions]

Your company has 10 separate Virtual Private Cloud (VPC) networks, with one VPC per project in a single region in Google Cloud. Your security team requires each VPC network to have private connectivity to the main on-premises location via a Partner Interconnect connection in the same region. To optimize cost and operations, the same connectivity must be shared with all projects. You must ensure that all traffic between different projects, on-premises locations, and the internet can be inspected using the same third-party appliances. What should you do?

  • A. Configure the third-party appliances with multiple interfaces and specific Partner Interconnect VLAN attachments per project. Create the relevant routes on the third-party appliances and VPC networks.
  • B. Configure the third-party appliances with multiple interfaces, with each interface connected to a separate VPC network. Create separate VPC networks for on-premises and internet connectivity. Create the relevant routes on the third-party appliances and VPC networks.
  • C. Consolidate all existing projects’ subnetworks into a single VPCreate separate VPC networks for on-premises and internet connectivity. Configure the third-party appliances with multiple interfaces, with each interface connected to a separate VPC network. Create the relevant routes on the third-party appliances and VPC networks.
  • D. Configure the third-party appliances with multiple interfaces. Create a hub VPC network for all projects, and create separate VPC networks for on-premises and internet connectivity. Create the relevant routes on the third-party appliances and VPC networks. Use VPC Network Peering to connect all projects’ VPC networks to the hub VPC. Export custom routes from the hub VPC and import on all projects’ VPC networks.

Vote for D as you cannot have more then 8 NICs on the appliance. Here we have 10 VPCs

Option D is the most efficient, scalable, and cost-effective solution. It leverages a hub-and-spoke model with VPC peering, ensuring centralized routing, simplified management, and seamless traffic inspection via the third-party appliances.

A is wrong because I don't think you can have VLAN attachments from different projects B is wrong because you can't have 10 NICS on a Third Party appliance (max 8) C is wrong because each Third Party appliance interface must belong to a different VPC (so not possible to consolidate all in a single VPC) D is the right answer

Selected Answer: D
Option D is the recommended solution for this scenario. Option D involves creating a hub VPC network for all projects and creating separate VPC networks for on-premises and internet connectivity. This approach allows for the inspection of traffic between different projects, on-premises locations, and the internet using the same third-party appliances. It also allows for the export of custom routes from the hub VPC and their import on all projects’ VPC networks using VPC Network Peering. This solution provides a centralized management approach while ensuring the required level of security and isolation.
