To address the requirements of data residency, encryption key control, and access governance, the most comprehensive solution is to utilize Google Cloud's features designed for these purposes. Option D suggests using customer-managed encryption keys (CMEK) for controlling where encryption keys are stored, VPC Service Controls to configure where data is stored by restricting access to specific locations, and Identity and Access Management (IAM) policies to govern access to data. This approach directly addresses all three requirements without the need for complex application changes or compromising on data residency requirements by keeping data on-premises. Options A, B, and C either partially address the requirements or introduce unnecessary complexity and limitations.
