Answer: Google Cloud Dedicated Interconnect
The correct answer is A: Google Cloud Dedicated Interconnect. This option provides direct physical connections and RFC 1918 communication between your on-premises network and Google's network. Dedicated Interconnect supports transferring large amounts of data efficiently, which is essential given the 4TB database and the frequent large updates. It also ensures that traffic does not traverse the public Internet, providing a secure and private connection, meeting the requirement for private address space communication. The other options either do not provide sufficient bandwidth and security (e.g., Google Cloud VPN) or are not scalable and efficient for frequent large updates (e.g., a NAT and TLS translation gateway or a VPN server on a Google Compute Engine instance).
