GCP Professional Data Engineer Practice Question

Your company processes regulated healthcare data in a Dataflow batch pipeline that reads from Cloud Storage and writes to BigQuery. The security team mandates that no Dataflow worker VM may have an external IP address, yet the job must still reach Google APIs without manual proxy management. Which networking configuration best satisfies these requirements?

  • Start the Dataflow job with the no-public-IPs option and enable Cloud NAT or Private Google Access on the worker subnet so workers use only private addresses while accessing Google APIs.

  • Keep the default Dataflow network and place the project in a VPC Service Controls perimeter, accepting that each worker retains a public IP.

  • Run the job in a shared VPC subnet that assigns external IPs by default, but block all 0.0.0.0/0 ingress with firewall rules.

  • Migrate the pipeline to a private Dataproc cluster and expose the master node through TCP forwarding for API access.
