In a heavily regulated industry requiring data sovereignty, what combination of services and configurations should be used to maintain compliance while effectively utilizing BigQuery for analytics?

*In a heavily regulated industry where data sovereignty is a critical requirement, the best approach is to use BigQuery with custom encryption keys that are stored in Cloud Key Management Service (KMS) in the same region. This setup ensures that data is encrypted using keys that are under the organization's control and located within the same geographic region as the data, complying with data sovereignty regulations. BigQuery provides powerful analytics capabilities, and when combined with Cloud KMS for custom encryption keys, it adds an extra layer of security and regulatory compliance. Other options like BigQuery Omni, VPN, or Data Transfer Service do not directly address data sovereignty in the same way. BigQuery Reservations and IAM are important for resource management and access control but do not inherently ensure data sovereignty.*
