Google Professional Cloud Network Engineer Question 701
Single answerGoogle Cloud PlatformYour organization needs to establish a secure site-to-site data transfer between your on-premises network and a Virtual Private Cloud (VPC) on Google Cloud. The solution must ensure low latency, high security, and the ability to handle large volumes of data. Which of the following options should you implement?
- A
Set up a Cloud VPN with IPsec tunnels between your on-premises network and the VPC
- B
Use Cloud Interconnect with Dedicated Interconnect or Partner Interconnect
- C
Transfer data over the public internet using HTTPS
- D
Use a Cloud CDN to cache and transfer data between the on-premises network and the VPC
Show answer and explanation
Correct answer: B
Explanation
Cloud Interconnect (Dedicated or Partner Interconnect) is the best choice for secure, low-latency, high-throughput site-to-site data transfer between an on-premises network and a VPC. It provides a direct, private connection that can handle large volumes of data efficiently, meeting the organization's requirements. While Cloud VPN is secure, it is not optimized for high performance, and the public internet options lack the reliability and performance needed for this scenario.
- A. Incorrect.
Cloud VPN with IPsec tunnels provides encryption and secure connectivity, but it may not provide the low latency and high throughput required for transferring large volumes of data.
- B. Correct.
Cloud Interconnect (Dedicated Interconnect or Partner Interconnect) establishes a direct, private connection between your on-premises network and Google Cloud, ensuring low latency, high security, and the ability to handle large data transfers.
- C. Incorrect.
Transferring data over the public internet using HTTPS is secure but does not guarantee low latency or high throughput, making it unsuitable for large-scale data transfers.
- D. Incorrect.
Cloud CDN is designed for caching and delivering content to end users. It is not suitable for transferring data between on-premises networks and a VPC.
