Google Professional Cloud Network Engineer Question 94
Single answerGoogle Cloud PlatformYour organization is planning to build a global application that will serve users across multiple continents. The application requires low latency, high availability, and scalable interconnectivity between regions. As the network engineer, which Google Cloud networking solution should you implement to meet these requirements?
- A
Use Cloud VPN to establish secure tunnels between regions.
- B
Deploy a Shared VPC and use custom routes for interconnectivity between regions.
- C
Leverage Google Cloud's global Virtual Private Cloud (VPC) with subnets spanning multiple regions.
- D
Configure multiple regional VPCs and use VPC peering to connect them.
Show answer and explanation
Correct answer: C
Explanation
Google Cloud's global Virtual Private Cloud (VPC) is the best solution for global applications requiring low latency, high availability, and scalable interconnectivity. Unlike regional VPCs or VPC peering, the global VPC allows seamless interconnection across multiple regions without additional complexity. This makes it the most suitable choice for building a global application that spans multiple continents.
- A. Incorrect.
Cloud VPN is primarily used for securely connecting on-premises networks to Google Cloud or other cloud networks. While it provides secure connectivity, it is not optimized for low latency or global scalability for inter-region traffic.
- B. Incorrect.
Shared VPC allows projects to share a single VPC across multiple Google Cloud projects but does not inherently solve the problem of low latency and scalable global interconnectivity between regions.
- C. Correct.
Google Cloud's global VPC is designed to span multiple regions, providing low-latency, highly available, and scalable interconnectivity between regions. This solution meets the requirements for a global application.
- D. Incorrect.
While VPC peering can connect regional VPCs, it is not global in nature and has limitations in terms of scalability and managing traffic across multiple regions compared to Google Cloud's global VPC.
