Actual exam question from Google's Professional Cloud Network Engineer
Question #: 150
Topic #: 1
[All Professional Cloud Network Engineer Questions]

You have several microservices running in a private subnet in an existing Virtual Private Cloud (VPC). You need to create additional serverless services that use Cloud Run and Cloud Functions to access the microservices. The network traffic volume between your serverless services and private microservices is low. However, each serverless service must be able to communicate with any of your microservices. You want to implement a solution that minimizes cost. What should you do?

  • A. Deploy your serverless services to the serverless VPC. Peer the serverless service VPC to the existing VPC. Configure firewall rules to allow traffic between the serverless services and your existing microservices.
  • B. Create a serverless VPC access connector for each serverless service. Configure the connectors to allow traffic between the serverless services and your existing microservices.
  • C. Deploy your serverless services to the existing VPConfigure firewall rules to allow traffic between the serverless services and your existing microservices.
  • D. Create a serverless VPC access connector. Configure the serverless service to use the connector for communication to the microservices.

Selected Answer: B
Serverless VPC Access makes it possible for you to connect directly to your Virtual Private Cloud (VPC) network from serverless environments such as Cloud Run, App Engine, or Cloud Functions. Configuring Serverless VPC Access allows your serverless environment to send requests to your VPC network by using internal DNS and internal IP addresses (as defined by RFC 1918 and RFC 6598). The responses to these requests also use your internal network.

Serverless VPC Access is based on a resource called a connector. A connector handles traffic between your serverless environment and your VPC network. When you create a connector in your Google Cloud project, you attach it to a specific VPC network and region. You can then configure your serverless services to use the connector for outbound network traffic.
