Google PCA Designing for Security and Compliance Practice Question
An organization wants to use VPC Service Controls to protect a Cloud Storage bucket and a BigQuery dataset from data exfiltration. They want to allow access from a specific on-premises network via a Cloud VPN. Which TWO components are required? (Choose 2)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A service perimeter that includes the Cloud Storage bucket and BigQuery dataset
VPC Service Controls use access levels (often based on IP address) to allow or deny access. A service perimeter defines the protected resources. Cloud VPN provides the encrypted connection from on-premises. Cloud Interconnect is an alternative but not required. Private Google Access is for VMs in the VPC, not on-premises. VPC firewall rules do not apply to Google Cloud services.
