Google Professional Cloud Network Engineer Question 116
Single answerGoogle Cloud PlatformYour company operates workloads on both Google Cloud and AWS. You are tasked with establishing a secure, low-latency, and high-bandwidth connection between the two cloud environments to support data replication and hybrid application use cases. Which solution would best meet this requirement?
- A
Use Cloud VPN to establish an IPsec tunnel between Google Cloud and AWS.
- B
Set up a Cross-Cloud Interconnect to directly connect Google Cloud and AWS.
- C
Use a third-party network provider to establish a private connection between the two clouds.
- D
Leverage the public internet to connect workloads between Google Cloud and AWS.
Show answer and explanation
Correct answer: B
Explanation
When connecting Google Cloud and AWS for use cases requiring high bandwidth and low latency, Cross-Cloud Interconnect is the most suitable solution. It provides a direct and reliable connection between the two cloud environments, unlike Cloud VPN or public internet, which have limitations in terms of performance and reliability. While third-party providers can work, they are less efficient and harder to manage compared to Cross-Cloud Interconnect.
- A. Incorrect.
Cloud VPN provides secure IPsec tunnels but is not optimized for low-latency or high-bandwidth use cases. It's better suited for smaller-scale or less latency-sensitive connections.
- B. Correct.
Cross-Cloud Interconnect offers a dedicated high-bandwidth, low-latency connection between Google Cloud and other cloud providers like AWS, making it the ideal solution for this scenario.
- C. Incorrect.
A third-party network provider can provide private connectivity, but it introduces additional complexity, cost, and management overhead compared to Cross-Cloud Interconnect.
- D. Incorrect.
The public internet is not a suitable solution for this scenario due to its lack of security, unpredictable latency, and bandwidth limitations.
