Google Cloud Professional Cloud Security Engineer Practice Exam

To ensure secure connectivity between on-premises and Google Cloud applications, which method is recommended for transferring data at high bandwidth?

1. VPN Connection

2. Dedicated Interconnect

3. Cloud VPN

4. Standard Interconnect

The correct answer is: Dedicated Interconnect

The recommended method for transferring data at high bandwidth between on-premises and Google Cloud applications is Dedicated Interconnect. This option is specifically designed to provide private, high-speed, and low-latency connections. Dedicated Interconnect allows organizations to establish a direct physical connection from their on-premises network to Google Cloud, which can handle massive data transfer volumes and provides a consistent performance that is essential for demanding workloads. Dedicated Interconnect is particularly advantageous for large enterprises that require secure and efficient data transfer without the variability associated with internet-based connections. It bypasses the public internet, which significantly enhances security and reduces potential latency issues. In contrast, the other options may not provide the same level of performance. VPN Connection and Cloud VPN rely on the public internet, which can lead to slower speeds and potential bottlenecks. Standard Interconnect, while also a viable option, is typically geared toward interconnecting with lower bandwidth requirements compared to Dedicated Interconnect. Therefore, for organizations with substantial data transfer needs seeking secure, high-bandwidth connectivity, Dedicated Interconnect stands out as the ideal choice.
