To restrict traffic to a subnet hosting databases during your migration, which combination of GCP services and features should you use?

*Explanation: For restricting traffic to a subnet hosting databases during a migration, the most suitable combination of GCP services and features is to **Use Shared VPC along with Firewall Rules and Private Google Access** (Option C. . Shared VPC allows for resource isolation, while Firewall Rules control traffic access, and Private Google Access ensures limited access as needed for the database subnet. Option A (Create a VPC with custom firewall rules and monitoring Cloud NAT) is not the optimal choice as Cloud NAT is used for outbound traffic and not relevant in this context. Option B (Implement VPC Peering with custom IAM roles for limited access) focuses on connecting networks and IAM roles but does not control traffic access. Option D (Configure VPC with VPN and apply firewall rules for limited database access) is an overkill solution for this requirement. Option E (Use VPC Service Controls with custom Private Connectivity configurations) is more suitable for data exfiltration prevention use cases, which are not the primary concern here.*
