An enterprise requires on-premises workloads to privately access Google Cloud APIs and services without routing traffic over the public internet. The on-premises data center is connected to a Google Cloud Virtual Private Cloud (VPC) network via Cloud Interconnect. To comply with security policies, the API communication must be restricted to services supported by VPC Service Controls. Which combination of DNS and routing configurations should the enterprise implement?

Configure on-premises DNS to resolve `*.googleapis.com` CNAME records to `restricted.googleapis.com` (`199.36.153.4/30`), and configure custom BGP route advertisements on the VPC's Cloud Router to announce `199.36.153.4/30` to on-premises routers.: ### What Private Google Access for On-Premises Hosts Is **Private Google Access for on-premises hosts** provides private connectivity from hybrid environments (such as on-premises data centers or colocation facilities connected via **Cloud Interconnect** or **Cloud VPN**) directly to Google APIs and services using internal Google network paths rather than the public internet. ### How It Meets the Requirements - **No public internet traversal**: By establishing **Cloud Interconnect** or **Cloud VPN** and advertising the destination IP address range via **Border Gateway Protocol (BGP)**, on-premises hosts route outbound API packets across the private interconnect into the VPC network. - **VPC Service Controls compatibility**: Mapping `*.googleapis.com` domains to `restricted.googleapis.com` directs traffic to the dedicated IP range `199.36.153.4/30`. This special virtual IP (VIP) block allows access exclusively to Google services that support **VPC Service Controls**, blocking unverified or unsupported services. - **Custom BGP route advertisement**: Configuring the VPC's **Cloud Router** to advertise `199.36.153.4/30` ensures on-premises routers have an explicit route pointing to the Cloud Interconnect / Cloud VPN gateway for all Google API destinations. ### Key Advantages and Capabilities - **Explicit perimeter enforcement**: Guarantees that only VPC Service Controls-compatible Google APIs can be reached, mitigating data exfiltration risks. - **Deterministic routing**: Eliminates default internet routes for API endpoints by leveraging explicit host and subnet routes over private physical connections. - **Hybrid DNS flexibility**: Compatible with on-premises DNS forwarding zones, **Cloud DNS inbound server policies**, or response policy zones (RPZs). - **Centralized network governance**: Managed at the Cloud Router and BGP session level without modifying host-level network interfaces. ### Why This Is Optimal Using `restricted.googleapis.com` (`199.36.153.4/30`) combined with custom BGP route advertisements natively aligns hybrid routing topology with perimeter security controls, satisfying all security and zero-internet transit requirements.

A financial enterprise is securing communications between its Google Cloud VPC network and Google APIs to prevent data exfiltration. The security architect has established the following requirements: Global VPC workloads must be restricted so that they can only access Google APIs and services that are supported by VPC Service Controls (VPC-SC), automatically blocking calls to unsupported Google services. A dedicated analytics tier must consume Google APIs using an internal IP address allocated directly from the VPC subnet's private RFC 1918 range, allowing fine-grained VPC firewall rule enforcement and monitoring without routing to shared public VIP ranges. Which combination of private connectivity architectures should the architect implement?

Establishing private connectivity between VPC and Google APIs (Private Google Access, Private Google Access for on-premises hosts, restricted Google access, Private Service Connect).

An enterprise is deploying Compute Engine virtual machines without external IP addresses in a custom subnet (10.10.1.0/24). The workloads need to securely communicate with Cloud Storage and Artifact Registry while preventing data exfiltration to non-supported external services by leveraging an active VPC Service Controls security perimeter. The VPC network enforces a strict baseline egress policy with an explicit low-priority deny rule for 0.0.0.0/0. Which set of actions should the security engineer take to establish connectivity while maintaining network isolation and security perimeter enforcement?

A financial enterprise processes sensitive market data across Compute Engine instances, BigQuery datasets, and Cloud Storage buckets within Google Cloud. A security review identifies two primary data exfiltration threats: A compromised internal workload or malicious insider using valid credentials to copy proprietary BigQuery analytical data to an external, unauthorized Google Cloud storage destination. An administrator inadvertently misconfiguring IAM policies on a Cloud Storage bucket, granting read access to external or public entities. Which perimeter security architecture should the cloud security engineer implement to mitigate both exfiltration vectors?

A security engineer is evaluating IAM access across an organization's resource hierarchy structured as follows: Folder: Finance-Dept Project: fin-analytics-prod (child of Finance-Dept) Cloud Storage Bucket: fin-audit-logs (located inside fin-analytics-prod) The following IAM allow policies are currently configured: At the Finance-Dept Folder level, the principal auditor@example.com is granted the Storage Admin (roles/storage.admin) role. At the fin-analytics-prod Project level, auditor@example.com is granted the Storage Object Viewer (roles/storage.objectViewer) role. At the fin-audit-logs Bucket level, a local administrator attempts to restrict access by granting auditor@example.com only the Storage Object Creator (roles/storage.objectCreator) role. What is the effective permission state of auditor@example.com on the fin-audit-logs bucket, and why?

A security engineer is designing an organization policy rollout across an enterprise Google Cloud resource hierarchy consisting of top-level folders for Production, Development, and Public-Facing Web. The rollout must satisfy two primary requirements: Public access prevention must be enforced across all Cloud Storage buckets across the entire organization by default, while allowing an exception for a single project inside the Public-Facing Web folder hosting a public static website. A newly authored custom organization policy constraint targeting resource updates must be enforced without causing service update deadlocks on existing non-compliant resources. Which strategy should the security engineer implement to achieve these requirements?

A retail company stores several terabytes of structured transaction data in BigQuery tables. The data analytics team needs to train and evaluate a binary classification model to predict customer churn. The team wants to implement this solution using their existing standard SQL skills, without exporting or moving the data outside the data warehouse. Which solution should the team use?
